To determine the rewards policy, we read through Apple’s documents and found a solution.
That is “3.1.3 Other Purchase Methods” in the “App Store Review Guidelines”
In summary, purchase methods other than In-App Purchases are available under certain conditions. One of the conditions is that it is a multi-platform service. In that case, it will be granted access to features and services purchased on other platforms.
However, the same functions and services can be purchased through in-app purchases. Additionally, within the app, users must not be guided to anything other than in-app purchases.
For this reason, we decided to provide the full functionality of the Hepto app through In-App Purchases, and at the same time provide full functionality through the login function.
We will continue to consider the form of multi-platform services.
