Free forever · No credit card · 60-second setup
How it works
Synced in 60 seconds
Connect your accounts
Sign in and add your work and personal calendars.
Choose what to sync
Pick calendars, set direction, configure privacy.
Done — it's automatic
Events sync in seconds. You never think about it again.
Who it's for
Built for people who juggle calendars
Remote & hybrid workers
Your work Outlook doesn't see your personal Google Calendar. SYNCDATE makes your full availability visible — without exposing details.
Freelancers & consultants
Keep client calendars aligned without sharing details between them. When Client A books you, Client B sees you're busy.
Couples & families
Coordinate schedules without giving up privacy. See when the other person is busy — not what they're doing.
AI-augmented professionals
Claude, Cursor, or Windsurf can read every calendar you own and find free time across all of them in one call — via the SYNCDATE MCP server.
Anyone with 2+ calendar accounts
Google, Outlook, iCloud, Fastmail, Infomaniak, mailbox.org, Posteo, Nextcloud, or any CalDAV server — if you have two calendars, they should know about each other. SYNCDATE connects them in 60 seconds.

Questions
Is it really free?
Yes. 2 accounts and 2 calendars, free forever. No trial, no credit card. Paid plans start around the price of a coffee per month if you need more.
How many calendars can I sync?
Free plan: 2 calendars across 2 accounts, 1 sync. Plus: 20 calendars across 5 accounts, up to 5 syncs. Pro: 100 calendars across 20 accounts, up to 20 syncs. See pricing for current rates in your region.
What happens if I cancel my subscription?
Your syncs keep running until the end of your billing period. After that, syncs beyond the free tier limits are paused. You can always resume by upgrading again, or stay on the free plan with 2 calendars.
What calendars do you support?
Google Calendar, Microsoft Outlook, CalDAV providers (iCloud, Fastmail, Nextcloud), and iCal feeds. All support two-way sync except iCal, which is read-only.
Does it work with Google Workspace?
Yes. SYNCDATE works with both personal Gmail accounts and Google Workspace (business) accounts. You can sync between them freely.
How is this different from sharing my Google Calendar?
Sharing lets you see another calendar, but it doesn't block time or show up in "Find a Time." SYNCDATE actually syncs events so your availability is accurate to everyone scheduling with you.
What happens to recurring events?
Recurring events sync as full series, not individual instances. When you create a weekly meeting, the entire recurrence rule is copied — so all future instances stay in sync automatically.
How fast does it sync?
Fast enough that you'll never notice a delay — each sync saves you about a minute of manual copying. Under the hood, changes propagate in ~4 seconds via push notifications, with a backup poll every 15 minutes.
Can I undo synced events?
Yes. Delete a sync and optionally remove all events we created. No orphaned "Busy" blocks, no calendar clutter.
Can my employer see my personal event details?
No. By default, personal events appear as "Busy" on your work calendar. Your colleagues see that you're unavailable — they don't see event titles, descriptions, or attendees.
Is my data safe?
We only access calendar data via OAuth. Tokens are encrypted with AES-256-GCM. Events are processed in memory during sync and not stored. Hosted in Germany (EU), GDPR compliant.
