# Calendar FreeSync

> Calendar FreeSync syncs Google Calendar, Microsoft Outlook, and iCloud Calendar availability and adds Pro tools for viewing calendars together and accepting bookings.

Calendar FreeSync helps freelancers, consultants, and other multi-calendar users prevent double bookings. Google and Microsoft connect through provider authorization; iCloud Calendar connects with an Apple Account email and encrypted, revocable app-specific password. FreeSync never receives the primary Apple Account password.
