**TECHNICAL SECURITY**

For the security-conscious:

→ Encryption: TweetNaCl secretbox (XSalsa20-Poly1305)
→ Key Storage: Android Keystore (hardware-backed)
→ Key Protection: BIOMETRY_ANY_OR_DEVICE_PASSCODE
→ Random Generation: Cryptographically secure PRNG

Your encryption key is generated on first launch and stored in your device's secure hardware enclave. It can only be accessed after successful biometric authentication.
