Private notes

Share a note that disappears

Your note is encrypted in your browser before anything is sent. We store only ciphertext and cannot read it. Share the link; the note is destroyed after it is read or when it expires.

Create a private note

20,000 characters left

Destroyed the first time it is opened. Expires unread after 30 days.

The note is encrypted in your browser. We never receive the text, the password, or the link secret. If you lose the link or password, the note is gone for good.

How private notes work

  • Your note is encrypted in your browser with a key that lives only in the link fragment, so the key never reaches our servers.
  • We store ciphertext and nothing else. Support staff, database backups, and anyone who obtained the stored row still cannot read the note.
  • The note is destroyed the moment it is read, or when its expiry passes, whichever comes first. A second visit to the same link shows nothing.
  • Use it for passwords, API keys, and one-off credentials — the things you should never paste into a public-IP room.

Sending the link safely

The link is the secret. Anyone who has it can open the note once, so send it over a channel you already trust and avoid posting it anywhere it might be logged, indexed, or forwarded — shared tickets, group chats, and public rooms all qualify. If you are sending a credential to a colleague, a short expiry plus a separate channel for the link is far stronger than emailing the credential itself.

If a recipient reports that the note is already gone, assume it was read and treat the contents as exposed: rotate the password or key rather than sending a second note. We cannot tell you who opened it, because we never had the key to begin with.
