Privacy
This site has no accounts, forms, cookies or adverts. It counts page views and page speed anonymously, with nothing that identifies you.
What is stored
Nothing about you, by this site. The maps and data are static files. Hovering, tapping, sorting and searching all run in your browser and are not sent anywhere.
Analytics and speed
The site uses Vercel Web Analytics and Vercel Speed Insights. Both are cookieless and store nothing on your device. They collect anonymous, aggregated data about page views (which pages are viewed, the referring site, the country, the kind of browser and device) and about how quickly pages load. There are no personal identifiers, and visitors are not tracked across days or across other sites. See Vercel’s analytics privacy notes.
Hosting
The site is hosted on Vercel. Like any web host, Vercel’s servers keep short-lived technical logs of requests, such as IP address, browser and the page requested, to run and protect the service. Those logs are covered by Vercel’s privacy policy.
Fonts and links
The typeface is served from this site, not from a font service. Links to sources, such as UCDP events and news reports, take you to other sites with their own privacy policies.
Changes
If what the site collects ever changes, this page will say so first. Last updated 14 October 2026.
