A reader asks:
Can Google delete apps from my Android smartphone?
Eh, yes, of course! There’s a push message and a mechanism for that implemented in the Playstore app. In case you find that surprising: how did you think Play would handle a cancelled payment for paid content? Return the money and let you keep the item?
In case the question was if you could buy an app, use Raccoon to download the APK to your PC, then refund, the answer is: yes you can do that (shame on you), most paid apps safeguard against this by performing an online license check.
