About this app

Keep private apps and personal media behind an extra layer of protection with App Lock.

Choose the apps you want to protect and unlock them with your PIN, pattern or fingerprint. App Lock also includes a private vault for photos and videos, plus tools that help you manage access and respond to unwanted attempts.

APP LOCK

Protect selected apps with a PIN, pattern or fingerprint.

Choose when apps lock again: immediately, when the screen turns off, or after a timeout.

Use a shuffled PIN keypad and hide the pattern path for added privacy.

Get alerts when a new app is installed so you can decide whether to protect it.

PRIVATE PHOTO & VIDEO VAULT

Import photos and videos into an encrypted, app-private vault.

Browse images and play videos inside the vault.

Restore items to your gallery when you choose.

Vault access requires your master credential.

EXTRA SECURITY TOOLS

Optional intruder selfie captures a front-camera photo after repeated failed unlock attempts.

Optional uninstall protection makes removal harder while it is enabled.

Optional trusted Wi-Fi rules can keep selected apps unlocked on networks you trust.

Optional home-screen icon disguises include Clock, Calculator, Weather, Voice Recorder and Compass.

PRIVACY BY DESIGN

Your app-lock credentials are stored as salted hashes. Vault media and intruder photos are encrypted on your device. LockNest's own app-protection data is processed and stored locally; advertising services may collect data as described in the Privacy Policy.

IMPORTANT

Usage access and permission to display over other apps are required for app-lock monitoring and the lock screen.

Camera permission is requested only if you enable Intruder selfie.

Location permissions are requested only if you enable Trusted Wi-Fi.

Uninstall protection and Trusted Wi-Fi are optional features.

Removing LockNest or clearing its data permanently deletes items stored in the vault. Export or restore anything you want to keep before uninstalling.

Take control of your app privacy with App Lock.
