COS is a private application used by one person (Connor, cstro.net) to manage his own calendar, email and tasks. It has no other users.
With the owner's consent, COS reads and writes the owner's own Google Calendar events and reads the owner's Gmail and creates drafts. This data is used only to plan the owner's schedule and prepare work for his review.
Google user data is stored on a private server controlled by the owner. It is not sold, shared with third parties, or used for advertising. Parts of it may be sent to the Anthropic API for processing on the owner's behalf, and are not used to train models.
COS's 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. Stored data can be deleted on request.
