Self-destructing notes

A self-destructing note is a private message that auto-deletes after it is read once. classified is the website that will self-destruct your note for you: it is encrypted in your browser, stored only as ciphertext, and the stored copy is destroyed on the first reveal. Use it as a temp note for anything you do not want left behind in email, chat, or a ticket.

Message autodestruction, the simple version

Most messaging tools keep a permanent, searchable copy of everything you send. A self-destructing note flips that default: the content exists just long enough to be read once, then the stored copy is gone. There is no readable note sitting on the server, and the same link cannot reveal it twice.

When a temp note helps

Private notes

Send a personal or sensitive message you would rather not leave in someone's inbox forever.

Temporary details

Share a short-lived address, code, or instruction that is only relevant for a moment.

Credentials hand-off

Pass along a password or access detail that should disappear after it has been used.

Quick secrets

Drop a one-time secret to a colleague without it landing in chat history or backups.

How the note self-destructs

classified encrypts the note locally and returns a single-use link. On the first deliberate reveal, the stored encrypted copy is consumed, so the message cannot be opened again. If the note is never opened, it still expires automatically on the lifetime you choose at creation.
