I like the part where you get a reward for just playing the game but going to your personal data collection and then selling it, I don't think so. facebook has been previously reported by that kind of idea but maybe they are reported because users didn't know that while working on this project, i think people would agree on it before getting started.
Its not selling perosnal data, its stuff like your purchasing history etc, so for example if you are a user that does alot of in-app purchases than you will recieve more ads regarding purchaes whereas if you are a f2p user you get more ads to like rewarded videos etc.
i think at least.
please correct me if im wrong
