@fxzxmic I think you made clear now, that you want a sync, but not a calendar function (that would get synced then) itself, correct?
There are some other existing feature requests around the topic of contacts/calendar sync, so just for the overview for now (and that probably should get “analyzed further” some time):
- Contact sync with mobile phone?
- BitWarden as a Contacts Manager with WebDAV
- (1/3) Bitwarden as secure Contacts app (recently closed)
- Add option to sync calendars via ICAL (recently closed)
