Analytics in the browser
The site uses PostHog to learn which pages and components are used and to find bugs. Once a page has loaded, it records page views, clicks, errors and a few events of our own, such as copying an install command. It may also record sessions, meaning how the page changes and where the pointer moves, to reproduce interface bugs, with what is typed into fields masked.
PostHog keeps an anonymous identifier in a cookie and in the local storage of this site, so that visits can be counted, and may use your IP address to estimate your country and city. The data goes through this site's own address to PostHog's servers in the United States.
Agents and programs
When the registry, the MCP server, llms.txt or a docs page in markdown is requested, the server records the address, the host and the User-Agent header, with no identifier for a person.
When an agent calls the MCP server, PostHog records the tool it called and its arguments, the name and version of its client, the model it reports and the reason it gives for the call. Email addresses, phone numbers and IP addresses are removed from that reason. Do not put personal data in the arguments of a tool.
Stored in your browser
The theme, the layout and the settings of the design system customizer are kept in the local storage of your browser, so the site looks the same on your next visit. They stay there.
Hosting
Cloudflare hosts the site. It processes each request, including your IP address, to deliver the page and protect the site from abuse. The fonts and scripts are served from this site: there are no third-party fonts, no ads and no trackers other than the analytics above.
Your choices
Clearing the cookies and the local storage of this site removes the identifier. To ask what we hold about you, or to have it deleted, write to contact.ouest.labs@gmail.com. This page changes when what the site records changes, and the date above says when it last did.
