How it works
We encrypt in your browser and only store ciphertext. The decryption key is never sent to the server.
Client‑side key
A random 256‑bit key is generated locally and embedded in the URL fragment (#k=...).
Strong crypto
Your note is encrypted with AES‑GCM in the browser before upload.
Ephemeral
Expiry, view limits, and burn‑after‑read keep your data short‑lived.
Private link
Share one link. The server stores ciphertext; the key stays in the link only.
Security
Defense‑in‑depth features for safer sharing.
Zero‑knowledge
Servers never see your plaintext or key.
Extra password
Optional password is combined with the key via PBKDF2 to derive the CEK.
HTTPS
Use HTTPS so keys and ciphertext can’t be intercepted.
Auto‑cleanup
Expired or exhausted notes are purged automatically.
