How Google Calendar shares free/busy availability
Google Calendar can share free/busy availability while hiding event details. That helps other people see when time is unavailable without exposing what the event is.
Calendar Sync
Keep work and personal calendars separate without getting double-booked.
Show the time as Busy on your work calendar without sharing what the personal event is. Your availability stays protected without copying private details.

Why free/busy sharing doesn't create protected work-calendar time
Heldrey solves a different problem: a matching personal event creates protected Busy time on the work calendar itself, without copying the title, description, attendees, location, or context.
The Heldrey rule
Mirror personal availability without copying private event details
Heldrey works on top of Google Calendar. The rule lives in Heldrey; the result happens in the calendar you already use.
