I have an Iphone application in which i am trying to implement non renewable subscription.I had done it a manner that after the purchase i am adding that details to user account information.so he can get it on all the devices.I have a login at the start of my application.And after associating the reciept data with the user account i was finding out the expiry date in my server from the purchase date in the reciept data, by using that information i was showing the buy button again to my user.But the apple is rejecting it for the reasons
11.6: Content subscriptions using IAP must last a minimum of 7 days and be available to the user from all of their iOS devices
17.2: Apps that require users to share personal information, such as email address and date of birth, in order to function will be rejected
Can anybody know the exact mechanism to implement nonrenewable subscriptions ?
From your description it sounds like your login when they start your app is mandatory. Apple forbids this. They insist that the login be optional, but it must still be available to everyone who wants to use it (when using non-renewing subscriptions).
What I did on my app was, next to where I show the user’s purchased subscription level, I have a button that says
Save your account.... And when they click it it describes to them how, if they create an e-mail and password than they can share their subscription across all their devices and they can restore their account if their iPhone gets lost or stolen. You want to incentivize the user to do this because a better experience for them means a better experience for you. You could even offer them a perk, like 2-weeks free if they create an account. And since you’re using non-renewing subscriptions, you have the power to do this since you’re calculating your own expiration date, instead of letting the app store do it for you.
