So I'm planning to create an app that licenses and sells original photos in my android app where as users can directly purchase from other user these items and get a direct link from the app after purchase, the users who purchase another user's photo can upload the photo into other apps like IG/FB/Twitter/etc. As per google pay SECTION 2: Permissible Payment Transactions Terms of Service I cannot use Google pay to sell digital goods....however in-app billing is only for digital content limited to the scope of my app...can someone please clarify what the hell is going on with google ?
To answer your question, like what you have mentioned above, In-app billing is only limited to your app, if you allow the user to use the digital photo outside of your app, it is not allow.
