How to read this list
Productivity apps tend to collect the work you do in them — documents, notes and files — so User Content is common. The question is whether it syncs to the developer's servers and how it is protected there.
Check whether the client connects to your provider directly or stores your mail on its servers.
Exposure follows the label's own structure: an app that declares any tracking is shown as “Tracks you”, even if it collects little else. Open any app for every data type explained and the iPhone settings that limit it.
