Calendar Sync
All your calendars, in sync.
A sync that works your way
Sync calendars one way or both ways, or bring several calendars together in one. Exactly the way your setup needs it.
Your data stays where you want it
For every sync you choose how much is shared: just a blocker, title and time, or all the details. Ridian never invites guests.
Every calendar works
Google, Microsoft, iCloud, GMX, WEB.DE, mailbox.org, iCal feeds and many more: you can sync them all with each other.
Contact SyncSoon
Your contacts, the same everywhere.
Your contacts always up to date
Change a contact with one provider and the change shows up in all your other accounts, whether between Google and Outlook or between two Gmail accounts.
No more double upkeep
You add a new number or a new contact just once instead of exporting or retyping lists, and your phone shows the right name on every call.
Alvin and your assistant know them too
Ask Alvin about someone and he finds them in your Google and Microsoft contacts, just like Claude and other assistants through Agent Connect, if you allow it.
How it works

From now on, everything stays in sync by itself. No more double bookings.
Frequently asked questions
What's included in Ridian Sync?
Calendar Sync and Contact Sync. Calendar Sync keeps your calendars in Google, Microsoft 365, iCloud and other CalDAV providers in sync. Contact Sync keeps your contacts in sync between your Google and Microsoft accounts, across providers too.
How fast does a change come across?
With Google and Microsoft, usually within seconds and at most a few minutes. Ridian checks iCloud, GMX and other CalDAV calendars, as well as ICS feeds, about every five minutes.
What does Ridian Sync cost?
One one-way sync is free. More syncs and two-way sync come with Basic and up. You'll find the limits for each plan on the pricing page.
Does Ridian keep a copy of my events?
Yes. To keep calendars in sync, we store the state of your source events. "Busy only" limits what reaches the destination calendar, where only the time slot appears.
Can my company decide what goes outside?
Yes, from the Team Growth plan. Your organization then sets the most detail your work calendars can share outside.
