Self-destructing note
Send something sensitive without leaving a permanent copy in someone's inbox or chat history. You get a link that works once. After the reader opens it, or after the time you choose, the note is deleted.
How it keeps the note private. Your browser encrypts the note with a random key (AES-256) before it is sent. Our server stores only scrambled data it cannot read, and deletes it when it is opened or expires. The key is in the part of the link after the
#, which browsers never send to any server, including ours. We do not store your address; a scrambled version is kept for one hour only to limit abuse.
What this does not protect against
- Whoever has the link can read it, once. Send the link privately. For more safety, add a passphrase and tell the reader by a different route.
- The reader can copy or screenshot the note. Nothing can stop that.
- Your message can still be seen on your device while you type it, and in your messaging app once you send the link. Delete the link from that chat afterwards.
- If someone else opens the link first, your reader finds the note gone. That is your warning that the link was intercepted.
- Server backups can hold an unopened note (in scrambled form) until it expires. It stays unreadable without the key.
- Text only, up to about 20,000 characters. For files, use the encryption tool.
This is a best-available precaution, not a guarantee. It complements, and does not replace, an end-to-end encrypted messaging app. Learn more in Encryption.
