Use of contacts by iOS apps
In my app privacy report I noticed that apps such as Reminders have accessed my contacts. This is despite my not knowingly set up any reminders that use my contacts. Other apps are Photos, Calendars, Health and Safari. I can probably understand Photos (for sharing) and Calendars (for invites), but not Safari and definitely not Health. Why do these apps access my contacts?
