Hi, I starting to work on an app where we like to have a yearly subscription model. But the main important thing is that we need to get the users mail adres , to send them some email and notifications about the app.
What is the best way, and supported by Google and Apple?
And is it possible to avoid the stores fee with subscriptions? Not a must, just a question.
When we put the app in the stores, is it possible to let the users first do an in-app subscription, or do we need some way to give them some free functionality in the app.
