Privacy Policy

1. Information We Do Not Collect

Unlike conventional benchmarking sites, Reaction Time Checker does not require registration, user accounts, passwords, or personal identity information. We do not collect:

• Names, email addresses, or phone numbers.
• Payment information or billing details (the tool is 100% free).
• Facial recognition, biometric sensor data, or keystroke logs outside the testing arena.

2. Local Browser Storage (LocalStorage)

To provide features such as your Personal Best score, Attempt History, and audio mute preferences, Reaction Time Checker stores lightweight numerical data directly on your device using your browser's window.localStorage.

This data remains exclusively on your machine and is never transmitted to or stored on our external servers. You can clear this data at any time by clicking "Clear History" or wiping your browser cache.

3. Server Logs and Edge Telemetry

When you request pages from our website, our global edge delivery network (Cloudflare Workers) may temporarily record standard technical headers for security and caching purposes (such as IP address, user-agent, and timestamp). These logs are strictly utilized for DDoS mitigation, edge caching, and server health monitoring.

4. Cookies & Third-Party Analytics

Reaction Time Checker does not deploy third-party advertising cookies, behavioral tracking pixels, or fingerprinting scripts. If third-party services (such as Google Search Console or privacy-friendly performance telemetry) are integrated, they comply with global privacy standards including GDPR and CCPA.

5. Children’s Online Privacy Protection (COPPA)

Our reflex testing platform is safe for audiences of all ages and does not knowingly collect any personally identifiable information from children under the age of 13.

6. Updates to this Policy

We may update this Privacy Policy periodically to reflect technological improvements or regulatory updates. Any changes will be posted on this page with an updated revision date.
