App Lock: Fingerprint, Pattern

Restricting access to private software and sensitive data becomes straightforward with App Lock: Fingerprint, Pattern. The app functions as a dedicated protector for individual applications, enabling users to secure items such as messaging platforms, social media, photo galleries, contacts, and system settings behind an authentication barrier. Using fingerprint recognition, drawn patterns, or passwords, it stops unauthorized individuals from browsing personal media, changing configurations, or reading private conversations when handling the device.

Locking Methods and Visual Customization

The tool provides multiple authentication options, allowing users to choose between a standard password, a drawn pattern, or hardware-based fingerprint unlock to access protected items. Beyond setting up the authentication screen, users can modify the appearance of the interface through several color choices and themes built according to Material design.

System Protection and Intruder Monitoring

Beyond safeguarding user-installed software, the app can lock core system settings. This prevents unwanted configuration adjustments, such as accidental data usage or unauthorized purchases, while also stopping other people from uninstalling existing applications. To catch unauthorized attempts, the service includes an intruder detection feature that automatically uses the device’s front camera to take a photo of anyone trying to open protected software without permission.

Required Operational Permissions

To function properly, the app relies on specific device permissions. It requires Usage Stats access to identify the active running application, Display Over Other Apps permission to overlay its lock screen when a protected item opens, and access to the installed app list so users can select which software to guard. Front camera access is strictly utilized for the intruder photograph feature.
