Secure Note / Self-Destructing Message Creator

Create encrypted, self-destructing messages with expiration timers and single-view access links.

Expires After

Notes are encrypted with AES-256-GCM and stored in your browser's localStorage. The decryption key is placed in the URL fragment (after #), which is never sent to any server. Notes are automatically deleted when they expire. Burn-after-read notes are destroyed after a single view.
