How to read this list
Business apps often handle other people's data — clients, colleagues and customers — so what they collect can affect more than you.
Check whether contact upload is optional, whether backups are encrypted too, and whether disappearing messages exist.
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.
