Send it once.
Then it’s gone.

Share a password or secret in a link that works one time. The note is encrypted in your browser and deleted after it is read or when it expires.

We never see the key or the text. Only ciphertext reaches our server.

How it works

Three steps, no account.

Built for sending credentials to a client, a colleague or a ticket without leaving a copy in an inbox.

Type a password, key or any secret. Add a passphrase if you want a second factor. Your browser encrypts it before anything is sent.

The decryption key lives after the # in the link, which browsers never send to our server. Send the link one way and the passphrase another.

Opening the link deletes the note from our server. Link scanners that only fetch the page do not use it up. Unread notes expire on their own.

Create and read notes through the API. You encrypt with AES-256-GCM on your side; the server only stores ciphertext.
