Privacy
AI Calendar has no accounts, no sign-in and no database of its own. This page lists everything the app stores or sends, and who processes it.
Stored in your browser
- Your events: saved in localStorage on your device. They are not uploaded anywhere except as part of a chat message (below). Clearing site data deletes them.
- Your AI Gateway key: if you add one, it is saved in localStorage and sent with each chat request as a bearer token. Remove it from the key dialog at any time.
Sent when you use the assistant
Each chat message is sent together with your timezone and your events from 45 days either side of today. The request goes to the agent runtime (eve) running on Vercel, which forwards it through Vercel AI Gateway to the language model provider (OpenAI). The runtime keeps the conversation's session state on Vercel for as long as the session lasts. Nothing is sent if you never open the assistant or send a message.
Analytics and hosting
The site is hosted on Vercel, which processes standard request logs. It uses Vercel Web Analytics for aggregate page-view counts and Vercel Speed Insights for page performance metrics; neither sets cookies. There is no advertising, no third-party tracking, and no data is sold.
