calMator syncs events between your calendars as "Busy" blocks — so people know when you're unavailable, without seeing why.
Be the first to know when we launch. No spam, just one email.
Connect any CalDAV-compatible calendar. Real-time sync for Google, polling for the rest.
Nextcloud, Synology, Radicale, Zoho, and any CalDAV-compatible service
From protecting personal time to managing multiple clients — calMator adapts to how you work.
Doctor visits, school pickups, therapy sessions — colleagues see "Busy" without the personal details.
Managing multiple clients? Your availability stays synced across all their calendars automatically.
Share when you're in meetings without exposing confidential work details to your partner.
Subscribe to regional holidays and have them blocked on your work calendar. No more meetings on bank holidays.
Automatically add travel time before in-person events. No more back-to-back meetings with commutes in between.
Event content is never stored. Synced events show as "Busy" by default — or any title you choose.
Link your calendars. We support Google Calendar, Outlook, Fastmail, and any CalDAV-compatible service.
Choose which events to sync, during what hours, and how they should appear. "Busy", "Holiday", or whatever you prefer.
calMator keeps your calendars in sync automatically. When plans change, your calendars update too.
Event titles, descriptions, and locations are processed but never stored. We only keep encrypted credentials and the minimal metadata needed to sync.
We make money from subscriptions, not your data. Your calendar information will never be sold, analyzed, or used for advertising.
Delete your account and all data is gone. For real.
Set it up once, then forget about it. calMator handles the rest.
Changes sync within seconds for Google. Other providers poll every few minutes.
Sync in any direction. Keep multiple calendars in sync with each other, not just one-way.
Sync only during work hours, skip all-day events, or exclude specific calendars.
Automatically block buffer time before events with physical locations.
Show "Busy", "Personal", or any title you choose. Your rules, your labels.
Connect as many calendar accounts as you need. No arbitrary limits.
