Data & permissions

What we ask for, and exactly why

Authenticator App - 2FA Auth is built to work without knowing who you are. Here is what stays on your device, what leaves it, and why each permission is requested.

Secrets stay on your device

Secret keys and the codes derived from them are encrypted with AES-256 and stored locally. They are never transmitted in plain text and never reach our servers — unless you deliberately switch on the optional encrypted backup.

Never leaves the device

No account, no personal data

The app needs no sign-up. We do not ask for your name, email address, phone number or contacts, and it never requests access to the accounts you protect with it.

Not collected

Limited technical diagnostics

To keep the app stable we may collect non-identifying information such as device model, OS version, crash reports, general region and the device advertising identifier. We never sell your data.

Anonymous only

Permissions the app requests

Each is asked for in context, used for one purpose, and nothing more.

  • Camera

    Requested only when you add an account, so the app can scan the 2FA QR code a service shows you. No photo or video is recorded, stored or uploaded.

  • Fingerprint & Face unlock

    Handled entirely by your device's biometric system. The app only receives a pass or fail result — your biometric data never reaches us.

  • Storage

    Used only if you enable encrypted backup, so the app can write and restore your encrypted vault file. Nothing else on your device is read.

  • Internet

    Used for crash diagnostics and, in the free version, advertising. Your codes are generated offline and never need a connection.

The full detail — retention, third-party services, children's privacy and your rights — is in our policy. Questions go straight to the publisher, Bocah Pinter.
