Google Calendar sync for Workspace and Gmail
Connect a company Google Workspace account, a personal Gmail account, or both. Each one blocks time in the others, and in any Microsoft 365 calendar you connect, without showing what the event is.
Accounts you can connect
| Account type | What Caltsu syncs |
|---|---|
| Google Workspace | Company or school accounts on your organization's own domain. Caltsu syncs the account's primary calendar. |
| Gmail | Personal Google accounts. Connect as many as you use. Each primary calendar joins your sync group. |
A Google primary calendar is usually named after its email address, and every block names its source calendar. If the address should stay private, rename the calendar in Google Calendar settings before you connect the account.
Permissions Caltsu requests
| Scope | Why Caltsu needs it |
|---|---|
| openid, email, profile | Identifies which Google account you connected. |
| calendar.readonly | Finds the primary calendar and reads its events. Caltsu uses the start, end and status, and keeps a change fingerprint of the title to notice edits. |
| calendar.events | Creates, moves and deletes the Busy blocks Caltsu places. |
Approval in the Google Workspace Admin console
Workspace administrators can decide which third-party apps users may connect. If your organization restricts unconfigured apps, the Google sign-in shows that Caltsu is blocked, and an admin has to trust it first.
Trusting the app lets users in the chosen organizational unit connect it. Caltsu asks for calendar access only. It does not request Gmail, Drive, Contacts or directory scopes.
