Follow up: Can someone help if the below exceptions to in-app purchases in the review guidelines might be applicable to the use case I explained above: 3.1.3 Other Purchase Methods: The following apps may use purchase methods other than in-app purchase. Apps in this section cannot, within the app, encourage users to use a purchasing method other than in-app purchase, except as set forth in 3.1.3(a). Developers can send communications outside of the app to their user base about purchasing methods other than in-app purchase. 3.1.3(a) “Reader” Apps: Apps may allow a user to access previously purchased content or content subscriptions (specifically: magazines, newspapers, books, audio, music, and video). Reader apps may offer account creation for free tiers, and account management functionality for existing customers. Reader app developers may apply for the External Link Account Entitlement to provide an informational link in their app to a web site the developer owns or maintains responsibility for in order to create or manage an account. Learn more about the External Link Account Entitlement. 3.1.3(b) Multiplatform Services: Apps that operate across multiple platforms may allow users to access content, subscriptions, or features they have acquired in your app on other platforms or your web site, including consumable items in multi-platform games, provided those items are also available as in-app purchases within the app. 3.1.3(e) Goods and Services Outside of the App: If your app enables people to purchase physical goods or services that will be consumed outside of the app, you must use purchase methods other than in-app purchase to collect those payments, such as Apple Pay or traditional credit card entry.
