I can receive information from you directly or take it from public sources, but only for direct contact with you on a one-time basis.
I don't know who buys my games, and I can only judge from the non-anonymous feedback I receive (e.g. on the Steam or Microsoft Store game page).
I can also email you if you give it in the feedback form. But I don't keep your email adress longer than 30 days and won't write to you again unless you want me to.
