AppVault: App Lock & Themes

Keep your personal apps behind an extra lock with AppVault. Lock selected messaging, social, gallery and other Android apps with a PIN, pattern or supported fingerprint unlock. Personalize your app lock screen with themes, wallpapers and your own photos.

From lending your phone to a friend to keeping everyday apps more private, choose what to protect and how to unlock it. Free app protection works without creating an account, and your protection settings stay on your device.

APP LOCK WITH PIN, PATTERN & FINGERPRINT
Choose a four- or six-digit PIN, draw a pattern, or use biometric authentication on a supported device. You can also choose Android's phone screen-lock authentication. Set a relock delay and manage your protected apps individually or in groups.

PRIVATE APP VAULT & OPTIONAL LAUNCHER
Organize selected app entries in an owner-protected vault. Use AppVault as your home launcher to keep those entries out of its app list. Hiding applies within AppVault; Android Settings and other launchers may still display installed apps.

LOCK SCREEN THEMES & WALLPAPERS
Browse anime-inspired artwork, nature, ocean, space, cars and abstract themes. Choose separate backgrounds for PIN unlock, pattern unlock and owner authentication. Select photos from your phone, change the accent color and add a personal lock-screen message. Apply a wallpaper to your phone's Android lock screen where supported.

INTRUDER PHOTOS & PROTECTION CONTROLS
Enable optional camera photos after failed AppVault unlock attempts. Check protection permissions, manage app locks and block screenshots inside AppVault. Choose an optional protection-status notification, or change the launcher icon and name using a calculator, notes, weather, gallery or settings disguise.

Premium APP LOCK
Free forever but with aditional premum features. A one-time Premium purchase removes ads, unlocks Premium themes and allows unlimited app locks. Sign in to your AppVault account to link verified purchases and restore access on your devices.

YOUR PROTECTION DATA STAYS ON YOUR PHONE
PIN and pattern hashes, protected-app selections, wallpaper photos and intruder images are stored locally.

ANDROID PERMISSIONS, UNDER YOUR CONTROL
App locking requires Accessibility access to detect selected apps and display-over-apps access to show the unlock screen. Accessibility events are processed locally; the service does not read screen text or share protection data with advertisers. Camera access is used for optional intruder photos. Notifications, biometric unlock, the home-launcher role and device administration are optional.

Make your app lock your own with AppVault.
