About SafeNote

SafeNote lets you send passwords, keys and other sensitive information without leaving a readable copy in chat histories, mailboxes or backups.

How it works

1. Write & encrypt. Your note is encrypted with AES-256-GCM in your browser using a random key that never leaves your device.
2. Share the link. The link holds the note ID and, after the “#”, the key. Browsers never send that part to the server.
3. Read once, then gone. The recipient’s browser decrypts the note, and the server deletes it permanently.

Why not just send the secret over chat or email?: Messages in chat apps and mailboxes stay around for years and are copied to backups and other devices. A SafeNote link leaves nothing readable behind once it has been opened.
Can SafeNote read my notes?: No. The decryption key is in the part of the link after “#”, which browsers never send to a server. We only store encrypted data that is useless without it.
What happens if I lose the link?: The note cannot be recovered by anyone, including us. Just create a new one.
What if someone else opens the link first?: The note will be destroyed and the real recipient will see that it no longer exists, so you will know it was intercepted.
