Military-Grade Encryption

Every note is encrypted with AES-256-GCM before it touches your disk. Your master password is strengthened through PBKDF2-HMAC-SHA256 with 310,000 iterations — the same standard used by security professionals worldwide.

Touch ID Unlock

Skip the password and unlock with your fingerprint. Your encryption key is stored securely in the login keychain and accessed only through biometric authentication. Notes auto-lock when hidden or on quit.
