What is Burner Note?

Burner Note is a free, open-source web tool that lets you send private messages that automatically self-destruct after being read. Every note is encrypted in your browser using AES-256 before it ever reaches a server, and the service operates on a zero-knowledge architecture—meaning even the platform itself cannot decrypt your content. No tracking, no ads, and no account required.

Who it's for

• Privacy-conscious individuals who need to share sensitive information like passwords, access keys, or personal details without leaving a permanent digital trail.
• Freelancers and remote workers who want a quick, secure way to send confidential instructions or credentials to clients or teammates without relying on email or chat logs.
• Security-minded teams looking for a lightweight, auditable tool that requires no setup, no accounts, and no third-party trust for one-off secure communications.

Key features

End-to-end AES-256 encryption in your browser

All encryption and decryption happens locally on your device using the AES-256 standard. The plaintext never touches the server, and the encryption key is never stored or transmitted—only you and your recipient can read the message.

Zero-knowledge architecture

Burner Note is built so that the service itself has zero ability to access your note content. Even if the server were compromised, the encrypted data would be useless without the key that exists only in your browser session.

Automatic self-destruction after reading

Once your recipient opens the note, it is permanently deleted from the server. There is no recovery option, no cached copy, and no backup—ensuring the message exists only for the moment it is needed.

Free, open source, and tracker-free

The entire codebase is open source for independent audit, and the service is completely free with no ads, no analytics, and no tracking scripts. Over 59,000 notes have already been securely destroyed.

What stands out

"We can't read your messages, and neither can anyone else."

This one-liner captures the core promise of Burner Note: true zero-knowledge security combined with radical simplicity. Unlike many encrypted messaging tools that require accounts, apps, or trust in a company's backend, Burner Note operates entirely in your browser with no persistent data. The combination of client-side AES-256 encryption, automatic deletion, and a fully open-source codebase means there are no hidden backdoors, no data retention policies to worry about, and no way for the service to ever see what you send.

Worth checking out if…

You need a dead-simple, no-account way to share a secret that must vanish after one read. Whether it's a password, a one-time link, or a confidential note, Burner Note delivers military-grade encryption with zero friction—and zero trust required.
