- The developer does not know anything about the customer except what is given in the Google payment details, and Play store statistics fed back thru the Play Developer Console. That data will not be used by the developer except for accounting and tax purposes, where required by the relevant tax authorities.
- My applications do not, to the best of the developer’s knowledge, send any data, anywhere, unless it is requested by the user.
- My paid applications are not part of any ad or statistics network.
To sum: the developer has no interest in, and is morally opposed to, the selling or otherwise abuse of any customer data. I do my best to not even collect any such data.
