I get that the app store is strict. But its strict for a reason. Apple or the app store isn't out to get your app or you.
moral of the story. spend 3 extra minutes writing something out and save yourself from a headache.
why are we assuming every person that reviews apps knows what ur app does? with submissions like this the explain it like im 5 approach is necessary.
For the permission request, I'd condense your paragraph into a sentence or two.
It's not unusual to download an app, but not launch it immediately. Demanding that the user remember your App Store description is unfair. It's your baby, not theirs.
They might not launch your app for hours or days after downloading. And Apple, reasonably I think, wants developers to try harder to accommodate user's realities.
