Obsidian calendar is a personal tool used only by its owner. It runs inside the Obsidian app (the TaskNotes plugin) on the owner's own computer.
It accesses the owner's Google Calendar only to create, update and delete the events that mirror his own tasks.
Data goes from the owner's computer directly to his Google Calendar. There is no server that stores it. Nothing is sold, shared with third parties, or used for advertising or to train AI models.
The use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Access can be revoked at any time at myaccount.google.com/permissions.
