System Tuner 3.20.8 requires the following permissions:

Allows applications to access information about networks.

Must be required by an AccessibilityService, to ensure that only the system can bind to it.

Allows an application to clear the caches of all installed applications on the device.

Allows applications to open network sockets.

Allows an application to call killBackgroundProcesses(String).

Allows an application to collect component usage statistics

Allows an application to read from external storage.

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

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

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

Allows an application to write to external storage.

Allows an application to read or write the secure system settings.

Allows an application to read or write the system settings.
