Who this is for

This application is operated and used by a single person, Katy Yut. It is not a product offered to other users. No data is collected from anyone other than the operator.

What data is accessed

• Google Calendar — read-only access to the operator's primary calendar events to compose daily digests.
• Google Sheets — read-only access to the operator's personal habit-tracking spreadsheet to compose daily and weekly summaries.

What's done with it

Event data and notes are fed to the Anthropic API (Claude) to compose summary text, which is then emailed to the operator's own inbox via Resend. Summaries and assistant state are stored in the operator's private GitHub repository.

Sharing

No data is sold, shared with advertisers, or made available to third parties beyond the service providers listed above (Anthropic, Resend, GitHub, Vercel, Cloudflare). Each of those processes data only as needed to deliver their respective services.

Retention

Calendar and sheet data is fetched fresh on each cron run and is not persisted by the application itself; only the derived summaries (in markdown files in the operator's GitHub repository) are retained.

Revoking access

Access can be revoked at any time via Google Account permissions.
