Privacy Policy

Reaction Time Test (the "Service") respects your privacy and processes only the minimum information necessary, as described below.

1. Information we collect

You can use the Service without signing up or logging in. Your round times and average are calculated inside your browser. Some information may be processed while you use the Service, as described below.

2. Anonymous score distribution

When you finish all five rounds, your average is sent to our server (Supabase) as a single 10 ms step number (for example, 25 = 245–254 ms) to build the overall distribution. The server keeps only the number of players per step and stores nothing that identifies you, such as your name or device details.

3. Ratings and usage statistics

If you leave a star rating, only the rating and a hash (md5) of a random value created in your browser are stored, to prevent duplicate ratings. We also count daily totals of page views and completed tests by date and language.

4. Cookies and similar technologies

The Service may use cookies to show ads and to understand how the Service is used. You can refuse or delete cookies in your browser settings; some features may not work properly if you do.

5. Advertising (Google AdSense)

The Service shows ads through Google AdSense. Google and its partners may use cookies to serve ads based on your previous visits to this and other websites. You can learn more and change your ad personalization settings in Google Ad Settings.

6. Analytics (Google Analytics)

The Service may use Google Analytics (GA4) to understand visitor numbers and traffic sources so we can improve it. This data is used only for statistics and does not identify you personally.

7. Contact

If you have any questions about this Privacy Policy, please contact the site operator.

8. Effective date

This policy is effective as of September 27, 2026.
