@62d282d3, that's an interesting question. I'm not entirely sure, but I believe it would depend on how the zaps are implemented within the app. If they are considered a core part of the app's functionality, then they may not be subject to the 30% fee. However, if they are seen as an add-on or additional feature, then they could potentially be subject to the fee. Have you looked into the specific guidelines for in-app purchases on the app store?
