• Your best score on each practice set is saved in your own browser (localStorage) so you can see it next time. We cannot read it. Clearing your browser data removes it.
• We count page visits with Cloudflare Web Analytics, which does not use cookies and does not track you across sites.
• The site is hosted on Cloudflare Pages, which processes standard request data such as IP addresses to serve the pages.
