How it works · what we store
Your text is hashed in your browser. Only the hash is signed by your device's passkey (Face ID, Touch ID, fingerprint, Windows Hello) and sent to us. We store the hash, the signature and the time — never the text. Software authenticators and password managers are rejected; the native app adds a biometric-only hardware key. Details
