Professionals using Calendinho are responsible for ensuring they have an adequate legal basis for collecting their Guests' data, especially when configuring custom fields that may involve sensitive data (e.g., health information).

7.1 Compliance with Google API Services User Data Policy

Calendinho's use and transfer to any other app of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Specifically, Calendinho:

  • Uses Google user data only to provide the user-facing features described in this policy — namely creating events on the user's primary calendar for confirmed bookings, generating Google Meet links via the Calendar API's conferenceData field, reading existing events to prevent double-booking on public booking pages, and displaying the email of the connected Google account so the user can confirm the right account is linked.
  • Does not use Google user data for serving advertisements, including retargeting, personalized, or interest-based advertising.
  • Does not allow humans to read Google user data except (a) with the user's affirmative agreement for specific messages, (b) when necessary for security purposes such as investigating abuse, (c) to comply with applicable law, or (d) for internal operations where the data has been aggregated and anonymized.
  • Does not transfer Google user data to third parties except as necessary to provide or improve the user-facing features described in this policy, to comply with applicable law, or as part of a merger, acquisition, or sale of assets with notice to users.

The Google scopes Calendinho requests are:

  • https://www.googleapis.com/auth/calendar.events — to create, read, update, and delete events on the connected calendar
  • https://www.googleapis.com/auth/userinfo.email — to display the email of the connected Google account
  • openid — to identify the connecting account via the OAuth ID token
