A Privnote Alternative with Zero-Knowledge Encryption

Burn Note is a free, no-sign-up tool for sending self-destructing notes. If you are comparing Privnote alternatives, these are the points worth checking — and how Burn Note handles each one.

How it works in 3 steps

1.Write and create
Encrypted in your browser. The key is kept in the link, not on our server.
2.Send the link to one person
Use any app. Opening the link alone does not reveal or delete the note.
3.They click Open Note
The note is shown once and deleted from the server right away.

Before you paste a secret

No account and no recovery: if the note is lost, it is gone.
Unread notes expire automatically, from read-once (7 days) up to 30 days.
A destroyed page means the note was opened or expired — Burn Note cannot tell which.

Try it now — write a note and get a one-time link in seconds.

What to check in a self-destructing note service

Where encryption happens: in your browser, or on the server.
Whether the server can ever see the decryption key.
Whether the note is deleted on read or merely hidden.
Whether you can add a password as a second factor.
Whether an account, email address, or tracking is required.

How Burn Note answers those questions

Encryption: AES-256-GCM, performed entirely in your browser.
Key handling: the key is in the URL fragment (after #), which is never sent to the server.
Deletion: the note is removed from the server when it is read.
Password option: an extra password protects the key with PBKDF2 (600,000 iterations).
No account, no email address, no sign-up.
