Sync your Google Calendars. Automatically.
Stop double-booking across multiple Google Workspace accounts. CalSync automatically copies events between your calendars so clients always see your real availability.
How It Works
Get up and running in under 2 minutes.
Connect Your Calendars
Sign in with Google and connect all the Workspace accounts you want to sync.
Set Up a Merge
Pick a source and destination calendar, choose busy-only or full details, and hit publish.
Never Double-Book Again
CalSync syncs every 5 minutes. New meetings, changes, and cancellations all stay in sync.
Everything you need to stay in sync
Unlimited Calendars
Connect as many Google Workspace accounts as you need. No limits on calendar connections.
Auto-Sync Every 5 Min
Events are automatically synced every 5 minutes. Accept a meeting and it appears across all your calendars.
Privacy Controls
Choose to copy full event details or just block time as 'Unavailable'. Your client info stays private.
Why CalSync?
You've probably tried other workarounds. Here's why they fall short.
Overlaying calendars side-by-side
You can see conflicts, but others can't. Clients and coworkers still book over you.
Manually blocking time
Tedious, error-prone, and you'll forget — especially when meetings change or get cancelled.
Scheduling tools like Calendly
Great for external bookings, but they don't sync your internal calendars with each other.
Zapier / Make automations
Complex to set up, fragile, and often cost more per month than CalSync.
CalSync is purpose-built for this one job: keeping your Google Calendars in sync, automatically.

"Setup took me about 90 seconds. Wish I'd found this years ago instead of manually blocking time across calendars."

"The privacy mode is perfect — my clients can see I'm busy without seeing each other's meeting details. Exactly what I needed."

How to Merge Google Calendars Automatically
Freelancers and contractors who work with multiple clients often manage separate Google Workspace accounts for each one. The problem? When you accept a meeting on one calendar, your other calendars have no idea you're busy. This leads to double-bookings, awkward rescheduling, and clients who question your professionalism.
Google doesn't offer a built-in way to merge calendars across different accounts. You can view multiple calendars side by side, but that doesn't block time or sync events between them. And there's no native option to automatically copy events from one Google Calendar to another. That's where CalSync comes in.
CalSync connects all of your Google Calendar accounts and automatically copies events from one calendar to another every five minutes. When a new meeting lands on your client A calendar, it instantly appears as a blocked time slot on your client B calendar — and vice versa. You choose whether to copy full event details or just mark the time as "Unavailable" to keep client information private.
No manual copying. No browser extensions. No forgetting to check your other calendar before accepting a meeting. Just connect your accounts, set up a merge, and CalSync handles the rest.
