I have a web app that I provide for free at the moment for my users. I'm building compatible iOS/Android apps, and I'm going to charge $5/month for either.
My question is how should I charge my users? I can charge them through the built-in subscription models in the iTunes/Google App store, but both take a heavy 30% cut from income...
Instead, I can just charge them through Stripe on my web app and then once they authenticate in the mobile apps, figure out that they've already paid.
From your experience, is this even allowed or possible? Would Apple or Google flag me for doing this, or ban my account? The "goods" of my service are purely digital (notifications for an eCommerce store).
Thanks in advance :)
