Connect your calendars, configure how events flow, and let Hetk keep everything in sync.

Google Calendar
Microsoft Outlook
Apple iCloud

Multi-Provider Calendar Sync

Sync events between Google Calendar, Microsoft Outlook, and Apple iCloud. Mix and match providers freely — sync your Google work calendar with your Outlook personal calendar, or keep all three in lockstep.

  • Google and Microsoft sync via real-time webhooks — changes appear in seconds
  • Apple iCloud syncs via CalDAV with automatic polling
  • Cross-provider support — 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 perfect mirror.

  • One-way sync — events flow from source to target only
  • Bi-directional sync — changes in either calendar are reflected 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 replaced with "Busy", description and attendees hidden
  • Show As override — set synced events to Busy, Free, or preserve 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 prevents the same event from being synced 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
