How Google OAuth works for scheduling apps. What permissions Cal Clear requests, what it can and cannot access, and how to revoke access.
How OAuth Works for Calendar Access
When you connect your Google Calendar to Cal Clear, you go through Google's OAuth flow. Google shows you exactly what permissions Cal Clear is requesting. You authorize Cal Clear to have those specific permissions. Google issues Cal Clear an access token, which Cal Clear uses to make API calls on your behalf.
What Cal Clear Requests
Cal Clear asks Google for three calendar permissions: free/busy (to ask 'Is this time slot free?' for a given account), read-only calendar access (used to list your calendars so you can choose which ones to check), and event editing (to add, move and cancel the booking events it creates). It never reads your other events' titles, attendees or descriptions, and it does not access other Google services.
How to Revoke Access
You can revoke Cal Clear's calendar access at any time through your Google account security settings: go to myaccount.google.com → Security → Third-party apps with account access → Manage access → Cal Clear → Remove access. This immediately revokes Cal Clear's ability to check your calendar.
Security Best Practices
Only connect Google accounts that are relevant to your scheduling. Periodically review your connected calendars in Cal Clear settings and remove any that you no longer use. Treat OAuth tokens like passwords — revoke them for applications you no longer use.
