Hi @marcus3u7 two points here:
This isn’t a case of whether or not you’re using something, it’s whether or not your app is capable of using something. These are Apple’s rules so we don’t have any say over what they require for their store.
Secondly, and more importantly, if you’re designing an app that is just a webviewer then your app won’t be approved by Apple’s review team. If you search the community for 4.2 minimum functionality requirements you’ll find lots of existing examples.
What sort of app are you hoping to publish and who are your intended users? Let us know a little more and we can help you build something that meets Apple’s requirements.
