Only the OAuth refresh token (encrypted in Supabase Vault), the target calendar ID, and the facility identifier. Event content, third-party PII, and any other data from Google Calendar are not stored.

Customers may disconnect the integration via the UnlockOS administrative panel or by revoking UnlockOS access in their Google Account's third-party app settings. The OAuth refresh token stored by the Company will be deleted within 30 days after disconnection. See the Google Calendar integration page for details.
