I am looking for a calendar that can be completely private. So far I have only found calendars that can have private events. I need a calendar to be in a members’ only section so the whole calendar has to be able to be private.
I realize this may not exist as I have been searching the internet for an hour on this subject.
In any calendar plugin it should really easy allow access only to logged in users: These looks pretty nice:

Then you must to put following code in a suitable hook to force login, ie, totally private access. 8)
