DAVx⁵ (CalDAV sync app) supports both PRIVATE and CONFIDENTIAL, so implementing this idea would allow users to choose between those options. They have different meaning. For instance, when person A shares a Nextcloud calendar with person B:
* PRIVATE events of person A won't show up to person B
* CONFIDENTIAL events of person A will show up to person B, but only that time is busy, without details of the event
There are already calendar apps supporting this out there. Would be cool if Business Calendar 2 would be capable of PRIVATE and CONFIDENTIAL too.
On Android side, both ACCESS_PRIVATE and ACCESS_CONFIDENTIAL exist, so this should be really easy to implement.
