Privacy
Plain English, because it is short enough not to need anything else.
What stays in your browser
Your lever scores, score history, completed plays, and any API key you paste into the chat live in your browser’s localStorage. They are not sent to our servers, and we cannot see them. Clearing your browser storage deletes them.
What leaves your browser
If you join the list, your email address is delivered to our inbox via FormSubmit. If you use the chat, your messages and current scores are sent to Anthropic’s API to generate the reply; we do not store them. If you paste your own API key, it is used only to relay your own messages and is never stored or logged server-side.
Analytics
We use Vercel Analytics: anonymous, cookie-free page counts. No advertising trackers, no fingerprinting, no data sales, ever.
