No accounts or contact collection
You do not need an account. This site does not ask for your name, email address, school, or test score.
Progress on your device
Your browser stores an unfinished practice session and up to 20 recent completed-session summaries in localStorage. This includes selected answers, question identifiers and local results. That progress is not uploaded as a personal record. Use “Clear saved progress” in the practice setup, or clear this site’s browser data, to remove it. If storage is blocked, you can still practice during the current visit.
Anonymous usage analytics
We use our self-hosted Umami service to understand page visits and whether tools are useful. It collects general page, referral, browser, device and approximate-location information. Practice events include fixed topic and question identifiers, score ranges, rounded skill rates, and broad duration ranges. We do not send selected answers, graph coefficients, raw elapsed times, names or email addresses with these events. We do not use tracking cookies or enable session recording.
Umami analytics is served from umami-analytics-puce.vercel.app. Cloudflare hosts the site and processes connection information, including IP addresses, to deliver and protect it. Blocking analytics does not prevent the practice tools from working.
