The app claims that local data is not stored on the device and highlights encryption, QR-based verification of encryption keys, three PIN codes for account access, and security alerts for hacking attempts. It also uses com.android.vending.BILLING, indicating support for in-app purchases. Overall, the security posture appears solid and aligned with typical secure-messenger expectations, though users should review permissions within the app for precise access controls.
