Creating a throwaway just in case. You don't have to follow Apple/Google terms as long as they don't catch you doing so, would not recommend doing this unless you want to risk being permanently banned by them. I have worked as a mobile dev for few companies which they put some sort of switch API inside the mobile app. When the latest version is sent for review, the server will return a false flag thus not showing any third party payment UI. After it is approved on the App store, the switch will return true then the app will use third party payment to circumvent Apple/Google 30% cut. I have seen more than a dozen app doing the same thing on App Store, I am not surprised that Apple doesn't have time to spot check these app in App store given there are millions of app in the app store.
