Calendar FreeSync keeps all your Google Calendars in sync automatically — so every client always sees you as busy when you are, no matter which calendar they check.
Who it's for
Working across Client A's Google Workspace and Client B's? Stay available on all of them without manually updating every calendar.
Keep personal and work calendars separate but perfectly in sync — colleagues won't accidentally book you during personal time.
Events from one calendar appear as busy blocks across all your others. Conflicts become impossible before they can happen.
How it works
Events are copied automatically using Google Calendar webhooks — no manual action needed.
Synced events are tagged so Calendar FreeSync knows not to copy them back again — ever.
Only sync events that match your rules — filter by title, keyword, or other criteria.
