Permissions:
android.permission.INTERNET
Self explanatory.

android.permission.WAKE_LOCK
The app keeps a wake lock during screen off so it can complete the quit process.

android.permission.ACCESS_COARSE_LOCATION
This is coarse location, not fine. I use this for basic analytics via Flurry. I can only tell general location from this, not where you live. ;)

com.android.vending.CHECK_LICENSE
Self explanatory.

android.permission.READ_PHONE_STATE
This is used by the license check to identify the hardware, nothing more.

android.permission.ACCESS_WIFI_STATE
Self explanatory.
