AppLock is an Android application that lets you put a lock on your apps and files. By doing this, it secures your device in ways that go beyond the regular Android settings. Unlocking something involves entering a password or a pattern, like how it usually works for most Android apps which provide that feature.

The app can lock many sorts of apps and files. AppLock can lock an app, keeping it from being used, uninstalled or altered. If you don’t want your photos and videos accessible to others who may be using your device, there is a feature for locking and hiding files. You can even customize a profile, setting a group of apps that can all be unlocked at once with the same password.

AppLock can be set to automatically lock or unlock something based on a time or location. There is also a quick lock switch which lets you lock something using the notification bar. AppLock doesn’t use much memory and has a power-saving mode to conserve battery usage.

Considering all the security advantages provided by AppLock, it is a good tool if you need to protect your apps, files, or mobile data from unapproved usage. There are free and paid versions available with different features.

Potentially dangerous permissions

  • GET_ACCOUNTS: Allows access to the list of accounts in the Accounts Service.
  • PROCESS_OUTGOING_CALLS: Allows an application to see the number being dialed during an outgoing call with the option to redirect the call to a different number or abort the call altogether.
  • READ_EXTERNAL_STORAGE: Allows an application to read from external storage.
  • READ_PHONE_STATE: Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
  • WRITE_EXTERNAL_STORAGE: Allows an application to write to external storage.

Other permissions

  • ACCESS_NETWORK_STATE: Allows applications to access information about networks.
  • ACCESS_WIFI_STATE: Allows applications to access information about Wi-Fi networks.
  • BLUETOOTH: Allows applications to connect to paired bluetooth devices.
  • BLUETOOTH_ADMIN: Allows applications to discover and pair bluetooth devices.
  • CHANGE_NETWORK_STATE: Allows applications to change network connectivity state.
  • CHANGE_WIFI_STATE: Allows applications to change Wi-Fi connectivity state.
  • DELETE_PACKAGES: Allows an application to delete packages.
  • GET_TASKS: This constant was deprecated in API level 21. No longer enforced.
  • INSTALL_PACKAGES: Allows an application to install packages.
  • INSTALL_SHORTCUT: Allows an application to install a shortcut in Launcher.
  • INTERNET: Allows applications to open network sockets.
  • KILL_BACKGROUND_PROCESSES: Allows an application to call killBackgroundProcesses(String).
  • MOUNT_UNMOUNT_FILESYSTEMS: Allows mounting and unmounting file systems for removable storage.
  • PACKAGE_USAGE_STATS: Allows an application to collect component usage statistics
  • READ_LOGS: Allows an application to read the low-level system log files.
  • READ_SYNC_SETTINGS: Allows applications to read the sync settings.
  • RECEIVE_BOOT_COMPLETED: Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
  • RESTART_PACKAGES: This constant was deprecated in API level 8. The restartPackage(String) API is no longer supported.
  • SYSTEM_ALERT_WINDOW: Allows an app to create windows using the type TYPE_SYSTEM_ALERT, shown on top of all other apps. Very few apps should use this permission; these windows are intended for system-level interaction with the user.
  • UNINSTALL_SHORTCUT: This permission is no longer supported.
  • USE_FINGERPRINT: Allows an app to use fingerprint hardware.
  • VIBRATE: Allows access to the vibrator.
  • WAKE_LOCK: Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.
  • WRITE_SETTINGS: Allows an application to read or write the system settings.
  • WRITE_SYNC_SETTINGS: Allows applications to write the sync settings.
  • android.permission.MANAGE_ACCOUNTS
  • android.permission.USE_CREDENTIALS
  • com.domobile.applock.permission.C2D_MESSAGE
