I'm trying to submit my app to the app store and it seems I have to write a privacy policy. I don't know where to start. My app uses Firebase to store info (profile info) and to run a chat between the users. It's free and I don't have adds... I'm developing it for a company.
Is there any free tool or something? I can't believe that every developer that submit an app knows how to do this, it has to be some guide to make it easier...
Thanks for the help
