I have an Android app in Google Play store.
I've discovered trough various Fabric events that somebody is reverse engeenering my app.
I have a piracy checker which triggers if somebody installs the app not from the Google Play store, and he also made numerous IAPs without the payment being paid.
I know both of these things by Fabric custom events.
I also get false new user alarms from a Xiaomi phone, which is far a typical sympthom when somebody is launching the application many times - like when changing and trying the code again and again.
As far as I know:
Reverse engineering for your own fun is absolutely legal.
But what if the guy decides he re-publish my app with some numbers and paramteres changed with some reskin?
Also he have bought about 100 IAPS that would cost like 270$, but it was free for him because he changed the code.
Is it legal? Could I report it to Google or something?
Thanks in advance
