In 3.1.3(f) - attached below for reference - it defines and deals with the concept of "Free Stand-alone Apps." In the definition, it has the text "(e.g. VoIP, Cloud Storage, Email Services, Web Hosting)". I interpret this parenthetical to mean that these are four EXAMPLES of Free Stand-alone Apps. In other words, there can be other apps that qualify under this clause, but the four mentioned are examples. Is this an appropriate interpretation, or should the interpretation be that ONLY those four types of apps qualify as Free Stand-alone Apps? 3.1.3(f) Free Stand-alone Apps: Free apps acting as a stand-alone companion to a paid web based tool (e.g. 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.
