The game does not collect any data, I have no idea who is playing, when, how, there are no cookies, no traces, no login, nothing, zip, nada. I have nothing to disclose since I collect nothing.
The only informations I can have are those provided by the store itself (that is, Google) which I can not "uncollect" as they are builtin and come with any app distributed by the store. They are purely statistical.
Google may or may not track you, I can not control what they do.
But I do not collect anything, you can audit the source code if you are curious.
