App Lock: fingerprint, PIN & pattern, photo vault, video vault & intruder alert.
App Lock: Fingerprint & Vault helps protect private apps, photos and videos with fingerprint, PIN or pattern security. Lock social apps, messages, gallery, email, notes and other personal apps while keeping private photos and videos inside a secure photo vault and video vault. Intruder Alert can capture a photo after failed unlock attempts, while App Disguise lets you change the launcher icon. 🔒 APP LOCK FOR PRIVATE APPS Use App Lock to protect apps you do not want other people to open. Choose the apps you want to protect and secure them with fingerprint, PIN or pattern. 👆 FINGERPRINT APP LOCK Unlock protected apps quickly with fingerprint authentication when supported by your device. Fingerprint App Lock provides convenient access to protected apps without entering a PIN every time. You can also use PIN or pattern whenever you prefer another unlock method. 🔢 PIN LOCK & PATTERN LOCK Create a private PIN or draw your own pattern to protect selected apps. PIN lock provides a familiar unlock method, while pattern lock offers a quick visual way to access protected apps. Choose fingerprint, PIN or pattern depending on how you prefer to secure your apps. 🖼️ PHOTO VAULT Keep personal pictures inside a private photo vault. Store photos you do not want easily accessible from your normal gallery and access them through App Lock protection. Photo Vault is useful for private pictures, personal albums and other images you prefer to keep in a protected area. 🎥 VIDEO VAULT Keep personal videos and private clips inside a protected video vault. Access them using fingerprint, PIN or pattern protection. Video Vault gives you a separate protected place for personal media you do not want easily visible in your regular gallery. 📸 INTRUDER ALERT Intruder Alert can record failed unlock attempts and capture an intruder selfie using the front camera when supported and enabled. If someone enters the wrong PIN or pattern, App Lock can help you review attempted access later. Captured photos can be reviewed from inside the app. 🎭 APP DISGUISE Make App Lock less obvious by changing its launcher icon. App Disguise lets you switch the visible app icon to another supported style so your privacy tools are less noticeable. ♿ ACCESSIBILITYSERVICE API USAGE App Lock uses the Android AccessibilityService API for its core app-locking functionality. When you enable this feature, AccessibilityService allows App Lock to detect when an app you personally selected for protection is opened so App Lock can display its lock screen before access to that protected app is allowed. AccessibilityService is used only after you choose to enable it for App Lock. It is used to detect the opening of protected apps and apply the lock screen at the appropriate time. You can disable AccessibilityService at any time from your device's Android Accessibility settings. App Lock: Fingerprint & Vault is a privacy and security app and is not an accessibility tool intended to assist users with disabilities. 🔐 PRIVACY FEATURES IN ONE APP • App Lock for selected private apps • Fingerprint App Lock • PIN lock • Pattern lock • Photo Vault • Video Vault • Intruder Alert • Intruder Selfie • App Disguise • Changeable launcher icon • Protection for selected apps • Private access to protected photos and videos Protect social apps, private conversations, personal photos, videos and other selected apps with flexible privacy tools in one place.
