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.
Doctor appointments, kid pickups, personal errands — show as busy without the details.
Subscribe to a holiday calendar and have those days blocked on your work calendar.
Freelancers and contractors can keep availability in sync across clients.
Let your partner see when you're in meetings without exposing work details.
Block time on team calendars based on your personal schedule.
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.
We store calendar metadata and sync state. Event details (titles, descriptions, locations) are never stored unless you enable features that need them.
Privacy-sensitive features require your explicit consent. We don't assume access.
Delete your account and all data is gone. For real.
Events sync within minutes of changes.
Only sync during certain hours, skip all-day events, exclude specific calendars.
Automatically add buffer time before events with locations.
Connect as many calendars as you need.
Works with Google, Outlook, Fastmail, iCloud, Nextcloud, and more.
Any calendar that supports CalDAV — including Google Calendar, Microsoft Outlook, Fastmail, iCloud, Nextcloud, Synology, and more.
Every few minutes. We're also adding webhook support for near-instant sync with supported providers.
Yes. Calendar credentials are encrypted at rest, and event details (if stored) are encrypted. We use industry-standard encryption.
No. We make money from subscriptions, not your data.
