Privacy Policy

Last updated: January 26, 2026

The Core Principle: Your Data is Yours

We believe your data belongs to you. Our service is designed from the ground up with privacy as a priority. We do not collect, store, or process any Personally Identifiable Information (PII) from our users. Your interaction with this game is anonymous.

How the Leaderboard Works (LocalStorage)

Your reaction time scores and the names you enter on the leaderboard are saved directly in your web browser's 'LocalStorage'. This is a standard, secure storage space on your own computer or device. We, the site operators, have no access to this information. It is never transmitted to our servers. You are in full control of this data and can clear it at any time by using the 'Reset Leaderboard' button in the game or by clearing your browser's cache.

Information We Explicitly Do Not Collect

To be perfectly clear, we do not track or store:

Your IP address
Your email address
Your geographic location
Any personal details beyond the optional name you enter for the local leaderboard
Your browsing habits or history

Third-Party Services (Google AdSense & Analytics)

To support the maintenance of this site, we use Google AdSense to display advertisements.

Google AdSense uses cookies to serve ads based on a user's prior visits to this and other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our sites and/or other sites on the Internet.
You may opt out of personalized advertising by visiting Ads Settings.

We also use Google Analytics to understand our website traffic and user behavior in an aggregated, anonymous manner to improve our service. This data is not linked to any personal information.
