Privacy
Short version: the tests run in your browser, we set no cookies, and your results are not sent anywhere.
Your results
Your reaction times and click counts are calculated in your browser. They are not sent to us or to anyone else, and the site has no server that accepts results.
What is saved on your device
Only after you finish a test (5 attempts, or a click-speed round), the page saves your best results (fastest single time, best 5-attempt average, best CPS per test length) in your browser’s localStorage under the name reactiontimetest.v1, so it can show them next time. This stays on your device. You can delete it with the “Clear saved results” button under the test or by clearing the site data in your browser. Nothing is saved if you leave before finishing, and no cookies are used.
Sound
The audio test plays a beep generated in your browser. The site never uses your microphone or camera.
Visitor statistics (Cloudflare Web Analytics)
To see how many people use the site and which pages they visit, we use Cloudflare Web Analytics, including for visitors from the EU and UK. It does not set cookies, does not use your browser storage or fingerprinting, and does not identify or follow individual visitors. We only see aggregated numbers such as page views per page, referring sites, countries and device types. A small script from static.cloudflareinsights.com reports each page view to Cloudflare. Your test results are not included.
Cookies and advertising
The site sets no cookies and currently shows no ads. We may show ads from Google AdSense later to keep the tests free. Before any ads go live we will update this page and, where the law requires it, ask for your consent through a consent message.
Hosting
The site is hosted by Cloudflare. Like any web host, Cloudflare processes technical data such as IP addresses to deliver pages and protect against attacks. See Cloudflare’s privacy policy.
Who is responsible for your data?
The party responsible for this website and its processing of personal data is Takreparation Skåne AB, Sparvgränd 6, 262 41 Ängelholm, Sweden, Org.-Nr 556988-5931.
