Privacy Policy

Last updated: 2026-06-02.

Your data

The reaction test runs entirely in your browser. Your scores and history are stored only in your browser’s localStorage on your own device. We do not have a server that receives, stores, or processes your test results, and we never sell or share them. Clearing your browser data removes this history.

What we collect

We may use privacy-friendly, aggregated analytics (such as Google Analytics or Umami) to understand anonymous, site-wide usage — for example how many people start a test. This data is not tied to your identity. If analytics are disabled, no such data is collected.

Cookies & storage

We use localStorage to remember your best score and recent results on your device. Analytics providers, if enabled, may set their own cookies or identifiers as described in their policies.

Children

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