AppLock

AppLock is a privacy-focused app security tool that lets you protect selected apps on your Android device with a PIN, fingerprint, or biometric unlock.

With AppLock, you can lock apps such as messaging, social media, banking, or any other sensitive apps to keep them private and secure. The app helps prevent unauthorized access by requiring authentication before an app can be opened.

Key features:

Lock selected apps with PIN or biometric authentication
Protect your personal apps from unwanted access
Simple and lightweight local device security
Works without creating an account
No ads or analytics
Security-focused design for private app protection
AppLock is built to work locally on your device and does not require external accounts or cloud services. It is designed for users who want better control over app access and personal privacy.

This app uses Android Accessibility Service and foreground service features only to detect when a protected app is opened and keep the lock screen active for security. AppLock does not collect or share personal data.
