What does "full access" to my calendar actually mean?
I use apps like Meetup that offer to add events to my calendar after I sign up for them. In Settings, Meetup has "add events only" authority. The other options are "none" and "full access." Right now, Events don't get added with "add events only," and Apple tech support told me that's because Meetup wants to add a map, note, and other things to the event (which would be fine with me). Tech support told me that because of this events won't be added unless I give Meetup full access.
I haven't been able to find anything written by Apple that explains what "full access" to my calendar means. To me it suggests that Meetup will have full access to (and can store on its servers) everything on my calendar, not just the events that relate to Meetup.
Does anyone know what "full access" means?
