Draw over other apps:
Allows the app to draw on top of other applications or parts of the user interface. They may interfere with your use of the interface in any application, or change what you think you are seeing in other applications.
Full network access:
Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.
Run at startup:
Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the device and allow the app to slow down the overall device by always running.
View network connections:
Allows the app to view information about network connections such as which networks exist and are connected.
