Short version: your scores are calculated and stored on your own device. We never receive them, we set no cookies and we run no advertising or tracking code.

Your test results
All timing and scoring happens in your browser. When you finish a round, the result — the score, the mode you chose and the date — is written to your browser’s local storage under the key dr-history-v1, so the page can show your history and personal bests next time. This data stays on your device. It is not sent to us or anyone else, and we have no way to read it.
You can delete it at any time with the “Clear this history” button on each test, or by clearing this site’s data in your browser settings. If your browser blocks storage, the tests still work and results are simply forgotten when you leave.
Share images
The result image is drawn on your device. Downloading it saves a file locally; using “Share…” hands the image to your device’s own share menu. Nothing passes through our servers.
Visit statistics
We use Cloudflare Web Analytics to count page views and measure page speed. Cloudflare states that it “does not use any client-side state, such as cookies or localStorage, to collect usage metrics” and does not fingerprint visitors. We only see aggregate figures such as page views, countries and load times — never who you are.
Hosting and security
The site is served by Cloudflare. Like any web host, Cloudflare processes your IP address and request details to deliver pages and protect the site from abuse; its handling is described in the Cloudflare privacy policy. We do not run our own server logs, and the pages themselves are static files.
What we do not do
- No accounts, sign-ups or forms that collect personal details.
- No cookies, advertising networks, social media widgets or third-party trackers.
- No camera, microphone or location access — the site’s security headers switch these off.
- No selling or sharing of data, because we hold none about you.
