Connect Google Calendar
You connect Google Calendar via account sign-in (OAuth) — no passwords stored with us. Available on all plans; after connecting, sync runs almost instantly (Google pushes changes to us directly).
Step by step
Section titled “Step by step”- In the dashboard, open “Connect calendar” and choose “Google Calendar”.
- Pick the right account in the Google window and sign in.
- Confirm access — leave all checkboxes ticked. If you remove one, sync will fail later and you’ll have to reconnect.
- Back in Kalender Sync: in the “Select Calendars” dialog, tick the calendars you want to use. You can change the selection any time in the settings.
Which permissions are requested — and why?
Section titled “Which permissions are requested — and why?”| Permission | What for |
|---|---|
| Read calendars & events | Detect your source events and pick up changes |
| Write calendars & events | Create, update and clean up blocker events in the target calendar |
| Basic profile (email) | Match the account to your Kalender Sync account |
Write access is required even though your original events are never modified — Kalender Sync only manages its own blockers. The full breakdown for IT and privacy teams: Permissions in detail.
Known pitfalls
Section titled “Known pitfalls”- Wrong account preselected — if you’re signed into several Google accounts, double-check the account picker. When in doubt, use a private browser window.
- Google Workspace: “App blocked” — your Workspace admin restricts third-party apps. The ways out: My organisation blocks the connection.
- “Please reconnect” after a few days — access expired or was revoked: Connection expired.
Disconnecting
Section titled “Disconnecting”How to remove calendars and revoke access (and what happens to dependent syncs): Remove calendars & revoke access. You can additionally revoke access at Google any time: myaccount.google.com/connections.
