Privacy Policy
Last updated: July 2026.
This page explains what happens to your data when you use Reaction Time Test.
Test results
Your reaction time results are calculated and stored entirely in your browser session. Scores, history, and stats reset when you refresh or close the page, and they are never sent to or stored on a server. Nothing about your individual performance is collected, tracked, or shared.
Downloads and sharing
The result card image generated by the "Download result card" and "Share on social media" buttons is created locally in your browser using an HTML canvas. If you choose to share it, that action is handled entirely by your device's own share sheet or the social platform you select; this site does not see or store the image or its contents.
Cookies and tracking
This site does not use tracking cookies, third party advertising scripts, or analytics that build a profile of you. It does not require an account, sign up, or login.
Third party fonts
Fonts are loaded from Google Fonts, which may log standard request data (such as IP address) as part of serving the font files, under Google's own privacy policy. No other third party resources are loaded by this site.
In short
Everything happens on your device. There's no account, no server side storage of your scores, and no advertising trackers.
