zero-knowledge · end-to-end encrypted

Notes that outlive your silence.

Write private notes, encrypted in your browser. If you stop checking in for a set number of days, they're released to the people you choose — with a link only they can open, using a passphrase you shared with them. The server only ever holds ciphertext, so it can never read your notes, even when it delivers them.

  1. 1
    Write & encrypt

    Notes are encrypted in your browser with a passphrase. It never touches the server.

  2. 2
    Check in

    Log in or click a reminder link. Each check-in resets the countdown.

  3. 3
    Go dark → release

    Miss the deadline and recipients get a link. They decrypt with your shared passphrase.

The trade-off of true zero-knowledge: because we can't read your notes, we also can't recover them. If you and your recipients lose the vault passphrase, the notes are gone for good. Share it carefully, ahead of time.
