What we collect
This site doesn't set cookies, doesn't run advertising or analytics scripts, and doesn't ask you to sign up for anything. Pages load the same for everyone.
Like every website, our web host keeps standard server logs: the address that made a request, the page requested, the time, and the browser's user-agent string. Those logs are used to keep the site running and to stop abuse, and the host deletes them on its normal schedule.
If you email us, we keep your message and address only as long as we need them to reply or to make a correction you asked for. We don't add anyone to a mailing list.
Links to other sites
We link to government pages, published research and other organizations. Their privacy practices are their own.
