Locker is an Android app developed by APUS APPS.

Locker first became available on 02 Mar 2015. It is estimated that Locker has been downloaded between 1000000 and 5000000 times from the Play Store.

Locker 1.0.7 requires the following permissions:

Allows applications to open network sockets.

Allows an application to read from external storage.

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.

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.

Allows an application to write to external storage.
