Privacy
What this site collects, and what it does not.
Analytics
Analytics is off right now: no measurement runs and no analytics cookie is set. If Google Analytics is enabled later, it will count visits and pages read under a random identifier, not your name, and this page will say so. To opt out then, block cookies in your browser or install Google's opt-out add-on.
The site chat
The chat answers questions about this design system and its site. When it is live, messages go to Anthropic, whose model writes the replies. For each exchange the site keeps the question, the answer, the page it was asked from, which model answered, timing and token counts, and a thumbs verdict if you leave one. Each entry carries a scrambled, one-way stand-in for your network address so abuse can be spotted; it is not your name, and it cannot be turned back into an address. Everything is deleted after 30 days. Do not type anything private into it.
What this site does not do
No accounts. No advertising. Nothing is sold or shared for marketing. The only data collected is the analytics and chat logs above, and both are used only to run and improve the site. The machine-readable endpoint at /api/mcp stores nothing: it reads published data and answers. An image you drop on the playground never leaves your browser: it is read there to sample its colours, and nothing about it is uploaded or kept.
