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.
