I went through this question,
which was marked as the original question for these questions, so we ask for clarification here.
A recently downloaded app named namedoreader does not mention that it contains in-app purchases, but does offer an in-app purchase with Paypal.
I want to implement Paypal in an app, but under what conditions does Google allow me to buy apps in an app?
