I am Ternox – solo developer and publisher. I committed to protecting and respecting your privacy. I don't collect personal data and we don't use cookies to collect personally identifiable information about you.
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.
