I'm going to be 18 this week and I'm concerned of Google having more power over my personal data et cetera. I've already migrated everything (mail, chat, storage, ...) to a self hosted server at home, but I can't delete my Google account because I paid 25 $ for the Google Play developer account, and I don't want to lose access to that. Is there any way to use the developer account without a Google account?
