I'm interested in unlocking features for a fixed time period in my iphone app via promo code. These same features are also offered for subscription outside of the app store. Is this still legitimate? It's imperative that the app isn't rejected by the app store for violating the terms of service.
Moreover, if we allowed the user to 'spend points' for this subscription (in app), would this be a violation? I suspect so but thought I would ask.
