From the article, emphasis mine: > Out of the blue, one day they said you have to add in-app purchase to stay in the App Store. They stumbled upon something in the app that mentioned there were paid plans, they went to the website and saw there was a subscription you could purchase, and then turned around and demanded we add IAP. It's apparently not just "no notifications". Below is the actual Apple guidelines. Notice that it is not "notifications", but "call to action". In practice, it may be "slightest hint". > Free apps acting as a stand-alone companion to a paid web based tool (eg. VOIP, Cloud Storage, Email Services, Web Hosting) do not need to use in-app purchase, provided there is no purchasing inside the app, or calls to action for purchase outside of the app
