I have a game on Google Play and IOS App Store that includes a small IAP to unlock extra levels.
I am considering producing an APK with the IAP completely removed and all levels available immediately after installation.
What is to stop this fully enabled APK being made available elsewhere after I send it to Amazon Underground. Can people get hold of this APK and install it on any Android device? - Is it modified by Amazon so that it will only function under the umbrella of Amazon Underground?
