Master App Lock – Secure Apps

Offline App Lock is the ultimate privacy and security tool designed to protect your sensitive applications. Built with a strict privacy-first approach, our app operates 100% offline, ensuring your personal data never leaves your device. Whether you need to secure social media, banking apps, emails, or business tools, Offline App Lock provides uncompromising security without the need for an internet connection.

🔒 Total Privacy, Zero Tracking Unlike other security apps, Offline App Lock works completely offline. We do not collect, store, or share your personal data, app usage habits, or passwords. Your security remains entirely on your device.

🔑 Robust Security Options • PIN Lock: Create a strong, custom PIN to secure any application on your device. • Biometric Support: Seamlessly unlock your protected apps using your device's fingerprint or face unlock (on supported devices). • Secure Reset Token: Forgot your PIN? Generate and save a secure reset token during initial setup to safely regain access without relying on email or cloud recovery.

🛡️ Advanced Protection Features • Customizable Lock Policies: Set how quickly an app re-locks after you exit it. • Intruder Prevention: Configure maximum failed attempt limits. Automatically apply temporary or permanent lockouts if someone tries to guess your PIN. • Invisible & Lightweight: Designed to be battery-friendly and run silently in the background without draining your device's resources.

⚙️ Business & Enterprise Ready Perfect for business accounts and enterprise devices, Offline App Lock provides a reliable, no-nonsense layer of security to ensure corporate data and communication apps remain strictly confidential.

⚠️ IMPORTANT PERMISSION NOTICE To function correctly, Offline App Lock requires the Accessibility Service API.

Why do we need this? This permission allows the app to detect when a protected application is launched so it can instantly display the lock screen and prevent unauthorized access.

Privacy Guarantee: We use the Accessibility API strictly for detecting app launches. We do not monitor your screen, read your messages, or collect any personal information using this permission. Your privacy is our top priority.
