What types of app require less privacy concern?

what types of app require less privacy concern? They are easier to get Apple’s approval? Thanks

I suppose any App that does not collect user information be that login details, address, phone number etc.

The kind of App that is a utility I guess.

I am thinking about building an app that introduces Macau. Does this kind of app have privacy concern?

My guess is that as long as the App does not require the user to supply any of his personal information then that will mean that it does not have any privacy issues.

You might still have to have some kind of link on the App by way of a loading screen to a privacy statement to effectively state that the App does not collect any user details.
