CasitaCalendar is a private family calendar app, self-hosted for personal household use. It is not a commercial service and is not offered to the public.
When you connect a Google account, the app requests read-only access to your Google Calendar and your account's email address. It uses these only to show your calendar events on the family calendar display and to label which account they came from.
OAuth tokens and calendar data are stored only in the app's own database on a privately hosted server. Nothing is sold, shared with third parties, or used for advertising or analytics.
You can disconnect your account from the app's calendar settings, which deletes its stored tokens. You can also revoke access at any time at myaccount.google.com/permissions.
The app's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
