JS Backup 4.2.3 requires the following permissions:

Allows an app to access approximate location. Alternatively, you might want ACCESS_FINE_LOCATION.

Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.

Allows applications to access information about networks.

Allows applications to access information about Wi-Fi networks.

Required to be able to access the camera device.

Allows applications to change network connectivity state.

Allows applications to enter Wi-Fi Multicast mode.

Allows access to the list of accounts in the Accounts Service.

Allows applications to open network sockets.

Allows an application to read the user's calendar data.

Allows an application to read the user's call log.

Allows an application to read the user's contacts data.

Allows an application to read from external storage.

Allows an application to read the low-level system log files.

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 read SMS messages.

Allows applications to read the sync settings.

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 receive SMS messages.

Permission an application must hold in order to use ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS. This is a normal permission: an app requesting it will always be granted the permission, without the user needing to approve or see it.

Allows an application to request installing packages. Apps targeting APIs greater than 22 must hold this permission in order to use ACTION_INSTALL_PACKAGE.

Allows an application to broadcast an Intent to set an alarm for the user.

Allows access to the vibrator.

Allows using PowerManager WakeLocks to keep processor from sleeping or screen from dimming.

Allows an application to write the user's calendar data.

Allows an application to write (but not read) the user's call log data.

Allows an application to write the user's contacts data.

Allows an application to write to external storage.

Allows an application to read or write the system settings.
