MasterLock - Lock Apps, Guard

MasterLock is a secure app lock for Android. Lock the apps you choose with a PIN, pattern, fingerprint, or supported biometric authentication to protect your private messages, photos, social apps, banking apps, and settings. You can also save your notification history, hide selected notifications from the notification shade, and keep your private information under your control.

LOCK APPS YOUR WAY
Add an extra layer of protection before selected apps open. Choose a PIN, draw a pattern, or unlock with fingerprint and supported biometrics on compatible devices.

SAVE YOUR NOTIFICATION HISTORY
Never lose an important notification again. MasterLock securely saves incoming notifications, allowing you to read them later even after they disappear from the notification shade.

For even more privacy, you can hide notifications from selected apps in the notification bar and read them only inside MasterLock.

CATCH INTRUDERS
Enable Intruder Selfie to capture a photo after failed unlock attempts. Review unauthorized access attempts and know who tried to open your protected apps.

PROTECT YOUR APP LOCK
Turn on uninstall protection to require your passcode before someone can reach common uninstall and permission settings. It helps prevent others from disabling MasterLock without your approval.

DISGUISE MASTERLOCK
Use Icon Camouflage to change the MasterLock launcher icon and name. Keep your app lock less noticeable on your home screen.

PERSONALIZE YOUR LOCK SCREEN
Choose from lock-screen themes, colors, and images. You can also hide pattern lines, set re-lock behavior, and automatically lock newly installed apps.
