Calendars
Each member may link their own Google Calendar or Outlook, so their appointments appear in their day inside the cockpit. Reading only — the cockpit never asks for permission to write.
An appointment from a personal calendar shows to colleagues as Busy — its time, never its title — unless its owner chooses to share it. See Privacy.
Where it runs
On a private server belonging to the business that installs it. Command Center is private software: it is not a public service, and there is nothing to sign up for here.
