Privacy Policy

This Privacy Policy explains how Reaction Time Test ("we", "us", "the site", reactiontest.net) handles information when you use the reaction time test and related pages. Reaction Time Test measures your reflex speed entirely in your browser. You do not need to create an account or enter any personal information to use it. Last updated: July 2, 2026.

Information we collect

We do not ask for or store personal information such as your name, email, or address on our servers to run the test. The only inputs the test needs are your clicks, taps, and key presses, which are used in your browser to calculate timing. We do not sell personal information.

Local score history (your device)

To show your recent results and personal best, the site saves your scores in your browser using local storage. This data stays on your device, is not transmitted to us, and you can clear it at any time with the in-app "Clear" action or by clearing your browser storage for this site.

Cookies and similar technologies

The core reaction time test does not require cookies to function. However, third-party services we may use, such as advertising and analytics, can set cookies or use similar technologies (like device identifiers and local storage) to deliver and measure their services. You can control or delete cookies in your browser settings; disabling some cookies may affect how third-party features work.

Advertising (Google AdSense & third-party vendors)

This site may display ads served by Google AdSense and other partners to keep the tools free.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
• Google's use of advertising cookies (including the DoubleClick cookie) enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can opt out of a third-party vendor's use of cookies for personalized advertising at aboutads.info/choices or, in the EU, at youronlinechoices.eu.

For more information on how Google uses data when you use our site, see How Google uses information from sites that use its services.

Analytics

If analytics are enabled, we may use privacy-respecting tools to understand aggregate, non-identifying usage (such as which pages are visited) so we can improve the site. Review each provider's own privacy policy for details on the data they process.

Children's privacy

This site is a general-audience tool and is not directed to children under 13. We do not knowingly collect personal information from children.

Your choices

You can clear local score history in your browser, block or delete cookies in your browser settings, and use the ad opt-out links above. Because we do not hold personal accounts, there is no server-side profile to delete.

Changes to this policy

We may update this Privacy Policy as the site evolves or as required by advertising and legal standards. The "Last updated" date above reflects the latest revision.
