Privacy Policy

Last updated: July 2026

reflexzap.com ("we", "the site") provides a free browser-based reaction time test. This page explains what data is and isn't collected when you use the site.

How the test works

The reaction time test runs entirely in your browser using JavaScript. Your click and tap timing is measured locally on your device and is never transmitted to, or stored on, any server operated by this site. Your personal best and test history are saved only in your browser's local storage on your own device — we never see them. Clearing your browser data or using a different browser/device resets this history.

Cookies and advertising

This site may display advertisements served by third-party ad networks, such as Google AdSense. These networks may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the internet.

You can opt out of personalized advertising by visiting Google Ads Settings, or generally at aboutads.info.

Analytics

We may use privacy-respecting analytics to understand aggregate traffic (e.g. page views, approximate location by country, device type). This data is not linked to your reaction time results.
