Privacy policy
This policy applies to the Krypton app and krypton.today (the “service”), operated by Fantagram, Inc. (“we”). It sets out what we receive, what we don’t, and what we can’t read. The rules for using the service are in our Terms of use.
At a glance
- We don’t take your phone number or email to sign up or sign in. Your account is created and signed in with a key that stays on your device.
- Names, bios and photos, and posts, replies, chats and videos, are sealed on your device before they reach our servers. Neither the servers nor our staff hold the keys to open them.
- Our servers don’t store who is fam with whom, who brought whom in, or who sent what to whom. Your devices keep these. Deliveries go into numbered mailboxes that aren’t tied to accounts, and the sender is sealed inside.
- The servers still see some things as they happen — the IP address and time of each connection, which mailboxes one device asks for together, and live connections such as calls. Section 2 says exactly what remains.
- Our staff see only what is reported and requests sent directly to the Krypton team. A reported item is opened to us by the reporter’s device, together with its author’s signature.
- Krypton+ payments are handled by the app store. Your card number and Apple ID never reach us.
- We don’t run ads, sell personal data or use it for tracking.
1What we don’t receive
- A phone number, email address or any government ID number for signing up or signing in (if you email us, we do receive that email — section 2)
- Your address book, location, or advertising identifier
- Your recovery phrase. The 18 words are shown once on your device for you to write on paper. They aren’t sent to us, and they aren’t kept in the app, in Apple’s or Google’s cloud, or in backups. We keep only values derived from them that can’t be turned back into the phrase (section 2)
- Your PIN itself (we keep only a derived value used to check it — section 2)
- The secret in an invite link, a fam QR code, a fam link or a request link you send to a member to ask to join. It sits after the # in the link, so it never reaches the server. The app derives from it the number of a one-time mailbox and a key; the server sees the mailbox number, not whose link it is
- Which web addresses you preview (your own device fetches the link preview directly — section 3)
- Payment details such as your card number or Apple ID (Krypton+ payments are handled by the app store — section 2)
- The sound of your calls (it travels encrypted between the two devices — section 4)
Permissions the app asks for (all optional)
- Camera
- When you scan a fam QR code or an invite QR code. What the camera sees is read only on your device; it isn’t saved or sent.
- Photos
- When you choose photos or videos for a post or your profile, and when you save a photo or video to your photo library (saving asks only for permission to add). Only what you choose is resized and sealed on your device before upload.
- Microphone
- When you make or answer a call with someone in your fam. The sound isn’t recorded or stored.
- Notifications
- To receive notifications.
- Clipboard
- Only when you tap “Continue with my invite” on the first screen or “Open a link you got” on your QR screen, the app reads the clipboard to find a Krypton link and opens it in the app. Until you tap, the first screen checks only whether the clipboard holds any text, not what it says. What’s on the clipboard isn’t sent to us. On iPhone, the system may ask whether to allow pasting.
If you don’t allow a permission, you can still use everything in Krypton except that feature, and you can turn permissions off at any time in your device settings. The app doesn’t ask for location or contacts access.
2What the servers know
Our servers don’t store relationships between members. Who is fam with whom, who invited or backed whom, and who sent a post, chat, card, note, call or notification to whom are kept on members’ devices; deliveries go through mailboxes. This section lists what the servers do store (they need it for the service to work, and it isn’t sealed), what they no longer store, and what they can see only as it happens. Emails to us, in the last row, come to our mailbox rather than the servers.
What the servers store
- Account number
- A random number created when you join. It isn’t tied to your name.
- Public keys
- Your account’s signing and encryption public keys (the encryption key has two parts, X25519 and ML-KEM-768 — section 15), a second signing public key (ML-DSA-65) kept for later use, and each device’s public key and certificate.Sign-in, checking who sent something, sealing things to you
- Membership
- Pending, active or suspended; your role (founder, Krypton team, member and so on); the order in which you became a member; the 30-day period in which you joined, signed by the server so other members’ apps can tell whether you joined as a new neighbor (section 6); whether you joined with an invitation ticket or through the Krypton team; your Krypton+ periods — the period you bought and any period given by a founder (who gave it is in the staff action log, section 8).Joining, deciding Krypton+ features (number of photos, video length, original quality, scheduled posts, calls)
- Tickets
- How many tickets of each kind your account received in each 30-day period — invitation tickets (5 a period, or 50 with Krypton+) and tickets that count new mailboxes, posts and photo uploads. A ticket is issued blind, so the server can’t later tell whose ticket is being used. When one is used, the server keeps a mark that it has been used, with its kind and period but no account and no date.The 30-day invitation limit, limits on posts and uploads, stopping mass creation
- Mailboxes
- Mailboxes are numbers worked out from a secret that only the two people in a pair (or the people in a chat) share; they aren’t tied to accounts, and the numbers change every 30 days. For each mailbox: the sealed notes in it (padded to set sizes), the hour each note was put in, the week the mailbox was made and last used, and a check value for the key needed to put notes in (only people who share the secret can). To stop abuse, the servers also keep daily counts per network area — the first part of the IP address mixed with a key that changes every day, not the IP address itself — for today and yesterday only.Delivering posts, chats, cards, notes, fam requests, call rings and alerts without the servers storing sender or recipient
- Mailbox wake-ups
- For each mailbox your device asks us to wake it for: a value made from the mailbox number, a random topic name, the kind of wake-up (such as post, chat or call) and the language. No account number and no push token are stored with them, except one iPhone call token per device, kept for the one mailbox that device uses for incoming calls and encrypted with a key the server holds. Google delivers the wake-ups by topic (section 10).Notifications
- Posts and notes
- Sealed, with no author field. Stored with each: a check value for a secret only the author’s device holds (it lets the author edit or delete without saying who they are), the kind of item, whether chat is closed, the disappearing time, the scheduled time (to the minute), when it was made, edited and deleted (to the hour), the number of photos, video length and whether original quality is used (to check Krypton+ limits), and the week the author’s device last renewed it (section 7). Who it was sent to, whose page a note is on, and who can open it are not stored.Delivery, editing and deleting, scheduled and disappearing posts, the 180-day renewal
- Chats
- Each chat is a room with a random label. The servers know which post a room belongs to (so, how many rooms a post has), and for each sealed line its size class, the hour it was put in and its order. Who wrote each line and who is in the room are not stored.Delivering replies only to the people in a chat, closing chats, clearing old chats
- Photos, videos and files
- Sealed files with random names, their size and kind, check values for the secrets needed to receive, keep and delete them, the day they were stored and the week they were last renewed. They aren’t tied to an account or to a post.Storing and delivering files
- Your card
- Which of Fam only or Everyone you chose for your card, and when you last changed it. A card set to Everyone is stored under your account number, sealed with the key every member holds (section 3). A card set to Fam only is stored sealed at a random location that isn’t tied to your account, with its size class and the week it last changed; the keys and the location reach your fam through mailboxes.Giving your card only to the range you chose
- Sealed backups
- Your fam list, the keys to posts you received, your blocks and your own posts’ secrets live on your device. So that you don’t lose them with your phone, your device backs them up to us sealed with your own key: monthly parts (the month, a size class and the hour last changed) and a fam-list bundle (a size class and the hour last changed). We can’t open them.Restoring your fam and received posts after recovery
- Recovery
- A backup of your private keys, sealed with a key that can be made only from your recovery phrase together with the server’s half; the server’s half; a check value for a lookup value made from your phrase (so a new phone can find your account from the phrase — the phrase itself and the lookup value aren’t stored); a value derived from your PIN to check it, with the number of wrong tries and any lock; and the status of a recovery in progress (the account, when it started and when the 48-hour wait ends). Recovery alerts go to all your devices.Getting your account back on a new phone. The server alone can’t open the backup; your phrase is needed
- Requests to the Krypton team
- The requesting account, an introduction sealed so only the team account’s key can open it, status and expiry (7 days), and signs used to spot abuse of sign-up — how many accounts were started from the same place on the same day, and how long it took from creating the account to sending the request. The Krypton team runs the service, so when the team lets someone in, the servers know that the team brought that person in.Screening requests to the Krypton team
- Sign-up start records
- When someone starts signing up: a check value made by mixing the first part of their IP address with a key that changes every day (not the IP address itself), and how many sign-ups were started with that check value that day. No account number or time is recorded. Records older than two days are deleted automatically every day.Stopping mass account creation, screening requests to the Krypton team
- Reports and staff actions
- Who reported, which post, chat room or person, for which reason, and the report’s status; the report itself, sealed so only our staff can open it (section 8); once staff confirm from the author’s signature who wrote a reported item, that author’s account; actions taken and notices sent to members.Handling reports and appeals
- Notifications
- Your device’s push token for notifications that go to your account (such as recovery alerts and notices from us), device type, notification language (Korean, English, Japanese), and which kinds you have turned on (chats, screenshots and saved photos, requests). A log of wake-ups sent (the topic mixed with a daily key, the kind and the time — no account), kept for two days. Notifications about a request to recover your account can’t be turned off.
- Devices
- Each device’s last sign-in time and whether it has been removed.
- Krypton+ purchases
- If you buy Krypton+: the store (Apple or Google), transaction number, product, the end of the current period (a lifetime pass has no end), when it was refunded or cancelled, and whether it was a live or test purchase. When you buy, your account number is attached to the transaction so the purchase the store confirms can be linked to your account. Payment details such as your card number or Apple ID are handled by the store; we don’t receive them.Working out your Krypton+ period and reflecting renewals and refunds, stopping one purchase being used by another account, keeping transaction records as the law requires
- Emails to us
- When you email support@krypton.today or privacy@krypton.today: your email address, the message and anything attached (such as proof that you hold rights, or screenshots that identify a post). The same applies to infringement or removal requests from people who aren’t members.Answering questions; handling appeals, infringement, removal, withdrawal and data-rights requests
What the servers don’t store
- Who is fam with whom; fam requests, introductions and their answers; who used whose QR code or fam link; who blocked whom. These are on your device and in your sealed backup.
- Who invited or backed whom. Joining uses anonymous tickets: the server checks that a ticket is valid and unused, not who gave it. The Backers on your card are proven by signatures your devices exchange. The exception is people the Krypton team lets in (see above).
- Who sent a post, reply, card, note, post passed to fam, heart, call ring, screenshot or save alert, or past posts to whom. The sender’s account and signature are sealed inside.
- Who is in a chat, and who invited whom into it.
- Whose page a note is on.
- Your Fam groups. They exist only on your device.
What the servers can see as it happens
“Not stored” isn’t the same as “never seen”. Even though the records above don’t contain relationships, the servers — and anyone who watches requests as they arrive or holds the platform logs (kept for 7 days, section 4) — can see the following at the moment it happens.
- Connections. The IP address and time of every request.
- Timing. If your app signs in and, from the same IP address at about the same time, puts notes into mailboxes or collects them, those mailboxes can be linked to your account. Joining works the same way: the invitation passes through one mailbox, so someone who watches requests or holds the platform logs could link the member who invited you to your joining. A request link you send to a member works the same way: the member who opens it can be linked to you. The stored records don’t show who brought whom in; connection logs and live requests could. Your app waits a few seconds to minutes between these steps, which blurs this but doesn’t prevent it.
- Batches. A device collects several mailboxes, posts, photos or cards in one request. While it does, the server sees that they belong to one recipient (not who). Posting to your whole fam sends notes in small batches spread over minutes, and each batch is visible as a batch as it arrives. The order in which rows were written also remains inside the database and its backups, even though stored times are rounded.
- Uploads. When your app gets a pass to upload a post or a photo, it is signed in, so the server sees at that moment that your account is uploading something of a given size — not who it’s for.
- Calls. During a call both devices are signed in to the same live channel, so the server sees which two accounts are on a call at that moment. It doesn’t record calls.
- Push. Apple and Google know which device a push token belongs to, and Google knows which device subscribes to which wake-up topic. Someone holding both our records and Google’s could link a device’s topics to its account.
- Reports. A report links the reporter to what they reported (section 8).
3What we store sealed
These are sealed on your device and then sent to us. Neither the servers nor our staff hold the keys to open them.
- Your card — your name, bio, profile photo and Backers. The Backers come with signatures that prove them: the first is the member who let you in, and the second is the first person other than them you became fam with, shown with a signature from you both that you are fam. If you are a Krypton+ member, your card also shows that (not your period or payments)
- Posts, replies, notes, chat lines, photos, videos and files (files are stored as ciphertext). The sender’s account and signature are sealed inside
- Link previews — made by the writer’s device and sealed with the post
- Fam requests — the shared secret for the pair, signatures, your card and a small profile photo, sealed so only the person you ask can open them
- Your card and small photo attached to your QR code or fam link — sealed with a key made from the secret after the # in the link, so only members who open the link can open them
- A request link you send to a member to ask to join — a note with your name, bio, account number and public keys, signed with your account key and sealed with a key made from the secret after the # in the link, in a one-time mailbox. Only people who have the link can open it. The servers don’t record who asked or who received it
- Invitation bundles — what the member who lets you in gives your new device (their signature on your key, their chain of Backers, the member key and your ticket), passed device to device through a mailbox
- The reason written when passing a post to fam, and the names of the people a post passed to you came through — the person passing it seals them with that post’s key. Only people who receive the post can open them
- Who invited whom to a chat, and the list of people in it — lines sealed inside that chat. Only the people in the chat can open them
- Your sealed backups (section 2) — only your own key opens them
- Your recovery backup — only a key made from your recovery phrase together with the server’s half opens it
- The name, one-line introduction and “who will you use it with” in a request to the Krypton team — only the team account’s key can open them (on the team’s device, or in a staff-console page where that key has been unlocked)
- The line carried in a chat notification — only the recipient’s device can open it
- Reports — sealed by the reporter’s device so only our staff can open them (section 8)
- Device names
What sealing doesn’t mean
- Recipients can read it. A post opens on each recipient’s device and may stay there. Recipients who are Krypton+ members can save photos and videos to their photo library, and saved copies are outside the seal.
- Reports are opened to us. The reporter opens that post, chat line or card to us (section 8).
- The Krypton team reads requests sent to it. The team opens the name, introduction and “who will you use it with” in the request and decides whether to accept (section 8).
- A card set to Everyone is visible to every member. By default your card is set to Fam only: its keys go only to your fam, one by one, through your pair mailboxes. If you choose Everyone on My page, your card is also sealed with a key every member holds (the member key), so anyone who becomes a member can see it. The servers know which you chose (section 2).
- Metadata isn’t sealed. The servers know what’s in section 2. Posts and notes are padded to set sizes to hide their length, but the size of photo and video files is visible.
When a link preview is made, the writer’s device connects to that site directly, so the site sees the writer’s connection. Recipients’ devices don’t contact the site unless they tap the link. For a YouTube video, the writer’s device fetches its title and thumbnail from YouTube, and a recipient’s device connects to YouTube (youtube-nocookie.com) only when they tap ▶ — YouTube then sees that device’s IP address and the video.
4Records created automatically
- IP addresses — we don’t record them in our database or server function logs. The exceptions are the daily counts in section 2 (sign-up starts and mailbox use per network area): the first part of the IP address is mixed with a value used only that day and kept for at most two days. Whoever holds the secret behind that daily value could work out the network area (not the full address) from a count. IP addresses, request times and request addresses do appear in the platform logs of Supabase, our server provider (request addresses can contain account numbers or mailbox numbers), and are deleted after 7 days. Cloudflare processes IP addresses while delivering photos, videos and web pages and while relaying calls; those records follow Cloudflare’s privacy policy and the periods Cloudflare sets. Observability logs for the Cloudflare Worker in front of file storage are turned off.
- Wake-up log, last sign-in per device, sign-up start records, mailbox counts — section 2
The “new message” and “typing” signals in an open chat pass through the server (Supabase Realtime) on a channel named from that chat’s secret, sealed with a key from the same secret. Anyone who has the chat’s secret — the people in the chat — can receive them. When the people in a chat change, the chat gets a new secret. The signals themselves aren’t kept.
Calls are one-to-one voice calls with someone in your fam. The two devices set up the call through a live channel named from their shared secret and seal the setup messages to each other. The sound is encrypted between the two devices and travels directly between them or, when a network needs it, through Cloudflare’s relay (TURN), which sees the two IP addresses but not the sound. We don’t record calls or keep a call history on the servers.
The app contains no analytics, advertising or crash-reporting tools.
5Purposes and legal bases
We use personal data only for the purposes below. For each purpose we list the information used and the legal basis.
- Providing the service

- Safety and operations
- Handling reports, restricting accounts, stopping mass creation of accounts and mailboxes, screening requests to the Krypton team, keeping a log of staff actions, answering questions and handling appealsInformation used — reports and staff actions, sign-up start records, mailbox counts, tickets, screening signs on requests to the Krypton team, staff action log, emails to usLegal basis — legitimate interests (PIPA Art. 15(1)(vi); GDPR Art. 6(1)(f)): protecting members and the service from abuse
- What the law requires
- Keeping purchase records, responding to legal requests, reporting child sexual abuse material, handling removal requests for infringing posts, withdrawals and data-rights requestsInformation used — Krypton+ purchase records, the information in section 2, report copies, emails to usLegal basis — legal obligation (PIPA Art. 15(1)(ii); GDPR Art. 6(1)(c))
We don’t use personal data for any other purpose, such as advertising, sale or profiling.
- We don’t process any information on the basis of consent. The camera, photos, microphone and notifications are used only when you allow them on your device, and you can turn them off at any time in your device settings.
- The information in section 2 is needed for the service (Krypton+ purchases only if you buy, and emails only if you send them). Without it you can’t use Krypton.
- You can object to processing based on legitimate interests (section 13).
We don’t receive or separately collect sensitive information such as health, beliefs or political opinions. The servers don’t store who is linked with whom, and know nothing of people’s professions or the nature of their relationships.
6What other members see
- Fam
- Your card — name, bio, Backers, profile photo and, if you are a Krypton+ member, that you are — and the posts you share with “Fam”.
- All members (card set to Everyone)
- If you choose Everyone with the small button at the top left of your card on My page (Fam only · Everyone), every member sees your card with a blurred (mosaic) profile photo. Your full photo opens only for your fam. The default is Fam only (founders start with Everyone). If you go back to Fam only, your device seals your card again with new keys and the copy sealed with the member key is deleted. What was already seen while it was set to Everyone can’t be undone (section 15).
- People who open your card
- Your Backers, and the signatures that prove them. When their app checks that you’re a real member, it also sees your chain of Backers (your Backers’ Backers, and so on).
- New neighbors
- From the 1,001st member on, someone who joins through a member’s invite link is a new neighbor until their second Backer is filled — that is, until they become fam with someone other than the member who let them in. Members’ apps tell this from the card and the server’s signature on the joining period (section 2), and don’t accept invitations, posts passed to fam, introductions or chat invitations from a new neighbor. People who joined before the 1,001st member, and people let in by the founder or the Krypton team, are full members from the start.
- The page owner’s fam (notes)
- A note you leave on another member’s page is seen by that member and their fam — your name is sealed in with it. Your device seals it only to the page owner and you; the owner’s device then seals it again to their fam. When someone stops being the owner’s fam or is blocked, the owner’s device stops sealing new notes to them; what was already seen can’t be undone. A note the owner hid stays hidden even if the writer deletes it and writes again. It’s fam only, whatever the owner’s card is set to. The owner can hide or delete notes on their page.
- Chosen recipients
- The post and a “Selected” mark showing it was sent to them in particular. They can’t see who else received it. The author sees the list of recipients.
- New fam
- Up to 100 of the posts you shared with “Fam” in the last 30 days. You can turn this off with “Show my past posts” in Settings; the setting stays on your device.
- People in a chat
- A reply to a post is seen only by the people in that chat. At first that’s the author and the person replying; if someone in the chat invites someone in their fam, the invited person sees the post and the replies from when they joined. People in a chat see who’s in it, who invited whom, and who joined or left. Anyone who leaves or is removed keeps the replies they received while they were in it. Only the author knows who sent a heart to the post.
- People a post is passed to
- If a recipient passes your post to someone in their fam, that person sees it too. They also see the names of the people the post came through — names sealed and attached by whoever passed it to them. Posts sent to chosen people and “Only me” posts can’t be passed to fam.
- The owner of a screen
- If you try to capture someone’s chat, page or post, they get a notification and your name appears in their updates.
- Authors (saving)
- If you save a photo or video from a feed post to your photo library, the author gets a notification and your name appears in their updates. Saving chat photos doesn’t notify anyone.
- People you ask to join your fam
- The person you send a fam request to sees your card and a small profile photo, even if your card is set to Fam only. Members who open your QR code or fam link see the same.
- People who get your request link
- Whoever has the request link you send to a member — anyone it’s passed on to — can open your name, bio, account number and public keys. If a member taps “I know them”, they become your first Backer; otherwise nothing is sent back.
- People in a chat, and owners you alert
- The people in a chat with you, and the owner of a post whose photo or video you save or of a screen you capture, see your card even if they’re outside the range you chose.
- Your fam link
- A fam link you send works once, within 24 hours: the first member who opens it becomes your fam without you confirming. Sending the link is your consent. You’re told, and you can remove them.
- Fam who relay a request
- If you ask someone who isn’t your fam to join your fam because you share someone in your fam, the device of that shared fam passes your request on automatically. That person’s device therefore knows that you asked whom (it can’t open the request).
- The Krypton team
- If you ask the Krypton team to join, the team sees the name, introduction and “who will you use it with” in your request (section 8).
By default your card is visible only to your fam, but if you choose Everyone or ask someone outside your fam to join your fam, others see it too. Don’t put sensitive things such as health or beliefs on your card. For posts, you choose who sees them with the audience setting (fam, chosen people, only me).
7Retention and deletion
Each kind of information is kept for the period below and deleted when that period ends. Cleanup runs automatically once a day.
- Notes in mailboxes
- Until the recipient’s device confirms it has them, and at most 90 days. A mailbox that has had nothing put in it for 70 days is removed.
- Mailbox wake-ups
- 100 days unless your device renews them
- Daily counts (sign-up starts, mailbox use per network area)
- Today’s and yesterday’s only (older ones are deleted automatically every day)
- Posts, notes and their photos and videos
- Until the author deletes them or deletes their account. The author’s device renews them in the background; anything no device of the author has renewed for 180 days — for example because the phone was lost and not recovered, or the app hasn’t been opened in that time — is deleted automatically. Your app renews them about once a month while it’s used, so they are deleted between 150 and 180 days after the app was last opened. A deleted post’s empty record (with no content) is removed after 7 days.
- Disappearing posts
- 24 hours (from when the post appears if chosen when writing, or from when it’s chosen later). Recipients’ apps hide it at that time; the servers delete it within the following hour. Its photo and video files are deleted by the author’s device, and in any case under the 180-day rule.
- Chats
- While the post exists. A chat with no new line for 365 days is removed, and the chats of a deleted post are removed 30 days after it’s deleted.
- Uploaded files not kept
- A photo or file that the uploading device doesn’t confirm within 7 days is removed
- Fam-only card locations
- An earlier version of your card is removed within 14 days of a new one; a location not refreshed for 90 days is removed
- Sealed backups
- While your account exists (monthly parts older than 24 months are retired). Deleted with your account
- Sign-in challenges
- 1 day after expiry
- Accounts that never finish joining
- A pending account that hasn’t joined within 30 days is deleted (unless it has an open request to the Krypton team)
- Request links
- The note in a request link’s mailbox is deleted after 30 days, and the requester’s device puts it in again every 7 days. The link closes when you join or cancel it, and ends with the pending account if that is deleted after 30 days (any remaining note is deleted within 30 days)
- Requests to the Krypton team
- 30 days after the request ends
- Recovery requests
- 30 days after the request ends; daily counts of recovery lookups, two days
- Wake-up log
- Two days
- Handled reports
- Once handling is finished and 180 days have passed since the report (open reports are kept; reports the law requires us to keep — for example, those reported to the U.S. NCMEC, for 1 year from that report — are kept for that period)
- Actions and notices
- Actions we took on an account and the notices we sent about them — 3 years from the action
- Staff action log
- Kept unalterable for 3 years from the action, then deleted
- Krypton+ purchase records
- 5 years from the transaction (the period Korea’s Act on the Consumer Protection in Electronic Commerce sets for payment records). Records of a pass still in use (a lifetime pass that hasn’t ended) are kept for as long as that account exists.
- Emails to us
- 3 years after we finish handling them (the period Korea’s Act on the Consumer Protection in Electronic Commerce sets for complaint and dispute records)
- Everything else
- While you use your account. What is deleted and what remains after you delete it is set out in section 12.
When a retention period ends or the purpose is fulfilled, we delete the information without delay. We delete the database rows and remove photo and video files from storage so they can’t be restored. Deleted information stays in the production database’s daily backups for up to 7 days before it’s gone (backups are used only to recover from failures). Records kept because the law requires it — purchase records, actions and notices, reports under legal hold — are stored apart from other information, keep the account number only as a number, and are used only for that purpose.
8Reports and what we can open
We can’t see posts as they are shared, and we have built nothing that would let us. Instead, when someone reports, the reporter’s device opens the reported item to us: it seals the item exactly as its author signed it, so that only our staff can open it.
We look at reported items to deal with breaches of our terms and unlawful content, and to take the action the law requires (section 5 — legitimate interests and legal obligation).
- A reported post, reply or chat line
- We see it as it was when reported, with its author’s signature, and the photos and videos referenced inside it (if the files still exist). From the signature we learn which account wrote it; the server checks the signature again before recording that account with the report. For a chat line, the reporter’s app also sends how many people are in the chat; we treat this as a hint, since it isn’t signed. If the post later disappears or is deleted, the sealed copy from the time of the report stays with the report.
- A reported person
- We see that person’s card as the reporter’s device opened it (name, bio, blurred photo) and, for a card set to Fam only, where it’s stored, so we can check the reporter didn’t make it up. The full photo isn’t sent.
- A request to the Krypton team
- The team account’s key (on the team’s device or in the staff console) unseals the name, one-line introduction and “who will you use it with”, and the team also sees how many accounts were started from the same place on the same day and how long it took from creating the account to sending the request. The team uses this to decide whether to accept. When a new request arrives, we email staff only the number of waiting requests and the staff-console address — no names or introductions.
- Metadata we see alongside
- The account numbers of the reporter and the reported person, the reason and the time. For each account: status, role, joining period, member number, Krypton+ period, number of devices and number of reports. No names. We don’t see how many fam or Backers someone has — the servers don’t store it.
- What a report links
- A report records that the reporter reported that post, chat room or person. A report about a chat line also links the reporter — and, once confirmed, the author — to that chat room. If a chat has two people or fewer, the app warns the reporter that the other person may be able to tell who reported.
- Staff action log
- Who took which action (holding or removing a post, holding a chat, suspending, lifting a suspension, handling a report, a founder giving or withdrawing Krypton+), on which account or item, when, and with what note — kept for 3 years from the action so it can’t be changed or deleted (section 7).
- What we don’t see
- Posts that weren’t reported, and that person’s other posts and chats
We can hold or remove a reported post or chat even before its author is confirmed. People who received a held post can tell it’s being held rather than deleted. When we remove photos or videos, we keep an evidence copy with the report for the report’s retention period. When we take action and know the author, we tell them the reason (until in-app notices are ready, they can ask support@krypton.today). We don’t tell them who reported. Appeals follow the process in section 6 of the Terms of use.
Because we can open report copies, they may be provided together with the report record when there is a legal request (section 9).
Handled reports are deleted once handling is finished and 180 days have passed since the report (open reports are kept; reports the law requires us to keep — for example, those reported to the U.S. NCMEC, for 1 year from that report — are kept for that period; section 7). The reporter’s account number stays on the record, so misuse of reporting is visible.
9Disclosure to third parties
We don’t sell personal data or hand it to other companies for advertising or marketing. We disclose it only in these cases.
- Legal requirements — we check that a request follows the procedure the law requires, such as a warrant, and provide only what is needed. All we can provide is what the servers store (section 2), what the platform logs still hold (section 4) and report copies opened to us (section 8). The servers don’t store who is fam with whom, who brought whom in, or who sent what to whom, so we have no such records to hand over, and we can’t open other sealed content. What the servers see only as it happens (section 2) isn’t stored, but it could be recorded if the law required us to. Where the law allows, we tell the member concerned.
- Reporting child sexual abuse material — if we find child sexual abuse material, we report it as the law requires to the U.S. National Center for Missing & Exploited Children (NCMEC) and the relevant authorities, together with the content and related account information.
- Imminent danger — when there is a clear and imminent risk to someone’s life or safety, we give the relevant authorities, such as the police, only what is needed to prevent it.
- Krypton+ payments — when a member buys Krypton+, their account number (a random number) is passed with the transaction to the store that processes the payment (currently Apple; Google Play payments on Android are still being prepared). From the store we receive only the transaction number, product, period and whether it was refunded. The store handles payment details under its own privacy policy.
10Service providers
We use the companies below to run the service. They handle sealed ciphertext, the information in section 2, and connection details while delivering data.
- Supabase, Inc.
- Database, server functions, Realtime (live signals in chats and setting up calls)
- Cloudflare, Inc.
- Storing and delivering photo and video files (ciphertext) — R2 and Workers. Delivering the krypton.today website and the invite, QR and fam link pages — Pages. Relaying call audio when a network needs it, and helping devices find a path to each other — Realtime (TURN and STUN); the audio stays encrypted. Forwarding email sent to support@ and privacy@krypton.today to our mailbox — Email Routing
- Zoho Corporation
- Our mailbox — stores the questions and requests emailed to support@ and privacy@krypton.today
- Apple Inc.
- Delivering iPhone notifications to your account (Apple Push Notification service) and ringing incoming calls (PushKit). We pass the device token and the notification text, which carries no names or content. Chat and call notifications also carry a line sealed so only the recipient’s device can open it; Apple sees only ciphertext. Apple knows which device a token belongs to.
- Google LLC
- Delivering Android notifications to your account, and mailbox wake-ups on iPhone and Android by topic (Firebase Cloud Messaging). We pass the device token or a random topic name and notification text with no names or content; for wake-ups we pass no account number. Google knows which device a token belongs to and which device subscribes to which topic.
We have data processing agreements with these companies so that they don’t use the information outside the work we give them and protect it to a standard equal to or higher than this policy. They pass work on to other companies only as those agreements allow. If the companies we use change, we’ll update this policy and let you know.
Krypton+ payments are processed by the store under its own responsibility, so they are covered in section 9 rather than here.

We can’t provide the service without these transfers. If you don’t want them, you can stop them by deleting your account (section 12).
EU and UK — South Korea is a country the EU and the UK recognize as providing an adequate level of data protection. Transfers to other countries rely on safeguards such as adequacy decisions or the EU Standard Contractual Clauses; you can ask for a copy at privacy@krypton.today.
Japan — our agreements require the receiving companies to take measures to the standard Japanese law requires. On request, we’ll tell you what those measures are and give you information about each country’s regime (for country regimes, see the Japanese Personal Information Protection Commission’s survey, 外国における個人情報の保護に関する制度等の調査).
12Deleting your account
This is how to delete a Krypton account (operated by Fantagram, Inc.). Delete it yourself under Delete account at the bottom of Settings in the app. If you haven’t finished joining (your request or application is pending, or it was declined) or your account is suspended, Delete account is at the bottom of the screen the app shows you instead. It works only on the device that holds your account key. It can’t be undone.
Deleting your account doesn’t cancel an auto-renewing subscription in the app store. Cancel it first in your device’s store subscription settings (Manage subscription in Krypton’s Settings). Krypton+ applies only to the one account that bought it, so when you delete your account any remaining period (including a lifetime pass) can’t be moved to another account or restored.
Your device deletes your content first
The servers don’t know which posts are yours, so your device does this. When you delete your account in the app, before the account itself is deleted, your device deletes from our servers every post, note, chat line, photo, video and file you wrote and your card, and tells the people who received them so that their apps delete them too. Your account is deleted only after the servers confirm this is done. If the connection drops, the screen stays on deleting until it can finish.
What is deleted
- Your posts, replies, notes, chat lines and their photos, videos and files, and your card (as above)
- Your account record itself — account number, public keys, membership and member number, Krypton+ periods (including any given by a founder) and ticket counts
- Devices and push tokens, your recovery setup, recovery requests, your sealed backups, notification settings, and your requests to the Krypton team
What is ended
- Your fam see your account as gone, and their apps remove you from their fam
- Your device closes the mailboxes and wake-ups it can
What remains
- Records kept for legal and operational reasons
- Krypton+ purchase records (5 years from the transaction; once your account is deleted, this applies to lifetime pass records too), actions we took on your account and the notices we sent (3 years), reports (180 days, or longer if the law requires), the staff action log (3 years) and emails to us (3 years after handling). These keep your account number as a number only; the account record they referred to is gone.
- Mailboxes and wake-ups
- They aren’t tied to your account, so we can’t find them to delete them. What your device couldn’t close is removed when its period in section 7 ends (90 and 100 days).
- Chat lines your device couldn’t find
- For example very old lines in a chat where you wrote more than 2,000 — they stay sealed until that chat is cleared (365 days after its last line).
- What went to others
- Recipients’ apps delete your posts when they receive your device’s notice; an app that isn’t opened within 90 days, or an earlier version of the app, may not. Copies recipients saved to their photo library, and screenshots, can’t be recalled. Replies others wrote to you remain theirs.
If you can’t use the app
If you no longer have a device with your account key, recover your account on a new phone with your recovery phrase and PIN, and then delete it — everything above is then deleted in the same way. If you can’t recover it, email privacy@krypton.today. We don’t collect names or emails, so if we can’t confirm you own the account we can’t delete it. Even when we delete an account this way, we can’t delete its posts, notes and photos, because the servers don’t know which are yours; they’re deleted automatically once no device of yours has renewed them for 180 days (section 7). They stay sealed until then — we can’t open them.
13Your rights and how to use them
You have the right to access, correct and delete your personal data and to ask us to stop processing it. In the EU and UK you also have the rights to restrict processing, to data portability, to object to processing based on legitimate interests, and to complain to a supervisory authority.
In the app
- Edit your profile, edit posts (up to 10 minutes after posting) or delete them, make a post disappear, close a chat, leave a chat or remove people from one (authors)
- Remove people from your fam, block someone, turn off “Show my past posts”, make a new recovery phrase
- Turn off notifications by type (chats, screenshots and saved photos, requests), Manage subscription
- Delete your account (section 12)
By contacting us
- Where — privacy@krypton.today. Requests are free.
- Verification — we don’t know your name or email, so we verify requests with a signature made with that account’s key. If you lost your device, recover your account with your recovery phrase first and then make the request. If we can’t verify you, we may be unable to act on the request, to the extent the law allows.
- Representatives — someone may make a request on your behalf. We need your authorization and a signature made with your account’s key to verify you.
- Access and copies — we can’t open sealed content, and the servers don’t know which posts are yours, so we provide what the servers store about your account (section 2). You can see your posts and other sealed content yourself in the app.
How quickly we answer
We answer within 10 days of receiving a request. If we can’t do it in that time, we tell you why and when we will (for EU and UK residents, within the one month the law sets).
We don’t make automated decisions without human involvement that significantly affect members’ rights.
Where to get help
If you don’t get an answer or think we handled a request wrongly, you can ask the bodies below for help.
- Personal Information Dispute Mediation Committee (Korea) 1833-6972 (kopico.go.kr)
- Personal Information Infringement Report Center (Korea) 118 (privacy.kisa.or.kr)
- Supreme Prosecutors’ Office (Korea) 1301 (spo.go.kr)
- Korean National Police Agency 182 (ecrm.police.go.kr)
- EU and UK residents — the supervisory authority where you live
- Residents of Japan — the Personal Information Protection Commission (個人情報保護委員会)
14Children
Krypton is a service for people aged 18 and over. We don’t knowingly collect personal data from anyone under 18, including children under 14, and members who invite others must not bring in anyone under 18. If we learn that someone under 18 has joined, we close the account and delete that information. If you know of such a case, please tell us at privacy@krypton.today.
15Security and its limits
Organizational measures
- We limit the people who handle personal data to a minimum number of staff. Staff access is granted through staff-console accounts kept separate from app accounts, with two exceptions: requests to the Krypton team are opened with the team account’s key (on the team’s device, or in the staff console — the console unlocks the team key, locked with a passphrase staff set, only inside that page; the server holds only the locked key and knows neither the passphrase nor the unlocked key), and Krypton+ is given or withdrawn from the founder’s app.
- Changes our staff make (holding or removing posts, suspending, lifting a suspension, handling reports, giving or withdrawing Krypton+) are kept for 3 years in a log that can’t be changed or deleted (section 7).
Technical measures
- Posts, profiles, chats and files are sealed on your device (end-to-end). Your account’s private keys stay in your device’s secure storage.
- Relationships aren’t stored on the servers (section 2). Deliveries go into mailboxes that only the people who share a secret can put notes into, and collecting them doesn’t require signing in. Stored times are rounded to the hour or week, and notes are sent in small batches spread over seconds to minutes, so stored records can’t easily be lined up by time.
- Protection against future quantum computers. Every outer layer that hands keys to a recipient — fam requests and the notes that set up each pair’s shared secret, sealed backups, recovery, invitation bundles, the member key and reports — is sealed with both X25519 and ML-KEM-768 (FIPS 203). Data collected today would need both to be broken to open. Posts and chats inside pair mailboxes are wrapped with the pair’s 256-bit shared secret, which is itself exchanged this way. The limits are listed below.
- Only server functions can use the database (row-level access control). File names are random, and receiving, keeping or deleting a file needs its own secret.
- All traffic uses encrypted connections (HTTPS).
- The staff key that opens reports stays on staff devices and is never sent to the server.
- Recovery needs both your recovery phrase (18 words, 192 bits) and your PIN. Five wrong PINs lock recovery for 24 hours. A recovery takes effect only after 48 hours, during which all your devices are alerted and you can cancel it from your old device.
- Notifications carry no names or content.
- App screens can’t be captured or recorded by default, including the screen that shows your recovery phrase.
- The production database is backed up daily (kept for 7 days).
- Records that are no longer needed are deleted after set periods (section 7).
Physical measures
Our servers are in Supabase (AWS) and Cloudflare data centers and are covered by those companies’ physical security controls.
The wider environment
We handle personal data in the United States and South Korea (staff, database); in Japan, Singapore, India, Australia, Canada, Brazil, Ireland, the United Kingdom, France, Germany and Switzerland, where server functions may run; and in the data center Cloudflare places in the Asia-Pacific region (Cloudflare doesn’t disclose the country). We take security measures after understanding each country’s data protection regime (section 11).
What we can’t prevent
- Someone photographing the screen with another device
- Recipients saving photos and videos to their own photo library (for feed posts the author is notified; for chat photos no one is)
- A recipient copying what they received elsewhere
- Linking by network and timing — someone who watches requests as they happen or holds the platform logs can link mailboxes, uploads, calls and joining to accounts by IP address and time (section 2). We don’t route requests through a relay that hides IP addresses.
- Protections that run on devices — blocking, the limit on how many times a post can be passed to fam, and one note per person on a page are enforced by the receiving members’ apps, not by the servers. A modified app can ignore them on its own side. Someone you blocked can still put notes into a mailbox; your app discards them.
- Someone collecting the cards members can see — we can slow this down, not stop it entirely
- The key every member holds (the member key) is shared by all members, so someone who gets hold of one member’s device together with a copy of the server data could read every card set to Everyone
- Changing who sees your card, or removing someone from your fam, doesn’t undo what they already saw. Someone you removed can still fetch the earlier version of your card until it’s removed (within 14 days), and the photos in posts they already received
- Your recovery phrase — anyone who has your phrase and PIN can take over your account after 48 hours unless you cancel from a device you still have. A photo of the phrase kept in a cloud service, together with a copy of the server data, would open your keys. If you lose both your phrase and every device, neither you nor we can restore your account
- A pair’s shared secret doesn’t change over time — if the shared secret between you and someone in your fam leaks, the sealed notes for that pair still on our servers (up to 90 days) could be opened
- Limits of quantum protection — signatures are still Ed25519, which a future quantum computer could forge (it couldn’t open past sealed content). We already create an ML-DSA-65 signing key for every account and plan to switch on dual signatures before practical quantum computers are expected. The ML-KEM and ML-DSA software we use hasn’t yet been independently audited. The anonymous tickets used for joining could be forged by a quantum computer, though not linked to who received them. The inner key envelopes inside pair mailboxes use X25519 behind the 256-bit shared secret. Transport encryption (TLS) depends on our platforms. None of this changes the metadata in section 2
16Tracking, ads and cookies
The app contains no analytics, advertising or crash-reporting tools. It doesn’t read advertising identifiers, doesn’t combine your data with other companies’ data, and shows no ads. We don’t let other companies collect members’ activity through the app or the website. Because we don’t track you, we don’t respond differently to a browser’s “Do Not Track” signal.
krypton.today uses no cookies. Only your chosen language is kept in browser storage (localStorage), and it isn’t personal data. It’s removed when you clear site data in your browser settings. Fonts are loaded from Google Fonts, so when you open a page your browser sends your IP address, browser information and the requested address to Google LLC (United States) (purpose: loading fonts; Google’s privacy policy applies).
The invite, QR and fam link pages don’t send the secret after the # in the link to the server; the page reads it only in your browser and hands it to the app. When you tap “Get the app” or “Open in the app” on an invite link page, the page puts that invite link on your clipboard so you can continue after installing the app; the app reads it only when you tap (section 1). The website is provided by Cloudflare, which sees access records (section 4). A YouTube video in a post plays from youtube-nocookie.com only when you tap ▶ (section 3).

18Changes to this policy
If we change this policy, we’ll tell you what is changing and when it takes effect, in the app and on this page, 7 days before it takes effect — or 30 days before for changes that are less favorable to you. Earlier versions will remain available on this page.
Until the official launch (public release on the App Store), changes take effect as soon as we publish them. The 7-day and 30-day notice applies from the version we confirm at launch.
This version: v2.0 · announced 2026-10-19 · effective 2026-10-20 (first published 2026-10-03). Until 2026-10-19, v1.3 (effective 2026-10-12) applies; before that, v1.2 (effective 2026-10-10) and v1.0 (effective 2026-10-08) applied. Each earlier version lists what it changed. v1.1, announced on 2026-10-09, never took effect.
Corrected on 2026-10-20: accounts that haven’t finished joining and suspended accounts can also delete themselves in the app (section 12).
What changes from v1.3:
- The servers no longer store relationships — who is fam with whom, fam requests and introductions, who invited or backed whom, who sent what to whom, who is in a chat, whose page a note is on, or blocks. We list what the servers still store, what they see only as it happens, and the exception for people the Krypton team lets in (sections 1, 2, 5 and 9).
- New records, none tied to relationships: mailboxes and their daily counts, mailbox wake-ups, tickets, sealed backups of your fam list and received posts, and authorless post, chat and file records (sections 2, 3 and 7).
- Joining is by a member’s invite link, or a request link you send to a member, with anonymous tickets; new neighbors; your card’s Backers are proven by signatures your devices exchange (sections 2, 3 and 6). Card settings are now Fam only and Everyone (Up to 2nd is gone); cards show a Krypton+ mark; fam requests and links carry a small photo; a fam link works for the first member who opens it; a fam who passes on a request knows who asked whom (sections 3 and 6).
- Recovery now uses a recovery phrase you write on paper and your PIN, with a 48-hour wait. There are no longer people in your fam who hold key pieces (sections 1, 2 and 15).
- Deleting your account: your device deletes everything you wrote from the servers and from recipients’ apps before the account is deleted, and the account record itself is now deleted. Posts no device of yours renews for 180 days are deleted automatically (sections 7 and 12).
- Reports: the reporter’s device sends the item as its author signed it; we confirm the author from the signature; what a report links; recipients can tell a post is held (section 8).
- Retention periods for the new records, and periods for actions and notices (3 years) and reports (180 days); the wake-up log is kept two days (section 7).
- The clipboard: an invite link page puts the invite link on your clipboard when you tap “Get the app” or “Open in the app”, and the app reads it only when you tap (sections 1 and 16).
- Calls and the microphone permission, Cloudflare’s call relay, and Google delivering mailbox wake-ups on iPhone too (sections 1, 4, 10 and 11). YouTube playback (sections 3 and 16).
- Protection against future quantum computers, and its limits (section 15).
- We now say “pass to fam” instead of “pass along” where that is what we mean. The meaning hasn’t changed.
- We now say “Backer” instead of “backer”; the Korean and Japanese versions use “Backer” too. The meaning hasn’t changed.
This policy is available in Korean, English and Japanese. If the versions differ, the English version prevails.
