Private Notes

Create encrypted, self-destructing notes

How it works — zero-knowledge encryption
  • Your note is encrypted in your browser using AES-256-GCM before anything leaves your device
  • The server only stores the encrypted ciphertext and a random IV — it cannot read your note
  • The decryption key is placed in the URL fragment (#), which is never sent to the server
  • Notes auto-expire after your chosen duration, and "burn after reading" deletes on first view
