Link Auth is a local authenticator app for storing and generating TOTP/HOTP one-time codes.
The current version does not collect, upload, share, or sell personal data.
Account names, issuers, authenticator secrets, and related settings you add are stored locally on your device and are used to generate one-time codes. Link Auth does not upload this data to a server.
Link Auth may request camera access to scan QR codes when adding authenticators. Camera input is used locally for QR code recognition and is not uploaded.
If you enable App Lock, Link Auth uses system-provided Face ID, Touch ID, or device passcode authentication. Authentication is handled by the operating system. Link Auth does not access or store biometric data.
The current version does not include advertising SDKs, analytics SDKs, or third-party tracking services.
