Features
Connect your calendars and pick how events flow. Hetk handles the rest.
Works with
- Google Calendar
- Microsoft Outlook
- Apple iCloud

Multi-Provider Calendar Sync
Sync events between Google Calendar, Microsoft Outlook, and Apple iCloud. Mix and match: sync your Google work calendar with your Outlook personal calendar, or keep all three in step.
- Google and Microsoft sync via real-time webhooks; changes appear in seconds
- Apple iCloud syncs via CalDAV with automatic polling
- Cross-provider: sync Google to Outlook, Outlook to iCloud, or any combination
Flexible Sync Directions
Choose exactly how events flow between each calendar pair. Set up one-way sync to copy events from a source calendar, or bi-directional sync to keep both calendars in step.
- One-way: events flow from source to target only
- Bi-directional: changes in either calendar appear in the other
- Per-pair configuration: each sync relationship has its own direction setting
Privacy Controls
Control what details are visible when events sync to another calendar. Keep sensitive meeting titles private, hide attendee lists, or show only that you're busy.
- Mark synced events as private: title becomes "Busy", description and attendees stripped
- Show As override: set synced events to Busy, Free, or keep the original status
- Identity transform: replace the organizer email with the target calendar's identity
Real-Time Automatic Sync
Events sync automatically as soon as they change. No manual copying, no scheduled batch jobs. Create an event in one calendar and it appears in the other within seconds.
- Google Calendar push notifications with under 10 seconds latency
- Microsoft Graph subscriptions with under 30 seconds latency
- Automatic webhook renewal: Hetk manages expiration and re-registration
- Built-in duplicate detection stops the same event from syncing twice
Simple Setup
Connect your calendar accounts, pick which calendars to sync, choose a direction, and you're done. The guided sync wizard walks you through each step.
- Sign in with Google, Microsoft, or Apple to link your accounts
- Select calendars and configure sync direction in a 5-step wizard
- Pause, resume, or reconfigure any sync relationship at any time
