I want to publish a simple app that doesn't collect any personal data. It is an offline game (noughts and crosses), that doesn't require any account, and stores only field state on the user's device. I don't have any server and don't transfer the data anywhere, so it's fully offline. But Google Play asks for a Privacy Policy. How can I get it? Is there any standard Privacy Policy for such type of application? Can I just write something like "We don't store and transfer any personal data"?
