Privacy Policy
Introduction
Last updated: September 12, 2026
Welcome to Reaction Tester. We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we handle information when you use our free online reaction time test.
Information We Collect
Automatically Collected Information
When you visit our website, we may automatically collect certain information:
- Browser type and version
- Operating system
- IP address (anonymized)
- Pages visited and time spent on pages
- Referring website addresses
Game Scores and Optional Accounts
Your browser stores recent scores and game preferences locally. Completed results from Reaction Time, Sequence Memory, Whack-a-Mole, Number Hunt and Math Sprint are also saved to our database to provide community rankings, share challenges and progress history:
- Best reaction times for each level
- Current level progress
- Game settings and preferences
Feedback Form (Optional)
If you choose to submit feedback through our feedback form, we collect:
- Email address (optional - only if you provide it for updates)
- Your feedback message
How We Use Your Information
We use the automatically collected information to:
- Improve our website and user experience
- Analyze usage patterns and trends
- Monitor and prevent technical issues
- Understand which features are most popular
We use feedback form submissions to:
- Improve our games and services
- Respond to your questions or concerns
- Send updates about new features (only if you opted in)
Cookies and Tracking
We use localStorage for recent game results, and essential cookies for guest identity and optional sign-in. The guest cookie lasts up to 180 days. Clearing it creates a new guest identity; signed-in history remains associated with your account. Local storage allows you to:
- See your best scores across sessions
- Resume from your current level
- Track your improvement over time
You can clear this local data at any time through your browser settings. Note that this will reset your game progress.
Third-Party Services
We may use third-party analytics services (such as Google Analytics) to understand how visitors use our site. These services may use cookies to collect information. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.
Data Security
We take reasonable measures to protect your information:
- All connections use HTTPS encryption
- Scores are stored with a game alias; authentication information is kept separate from public results
- We minimize the amount of personal data we collect
- Feedback submissions are sent through secure forms
Your Rights
You have the right to:
- Access: Request information about data we hold about you
- Deletion: Request deletion of your feedback submissions
- Opt-out: Unsubscribe from any updates (if you opted in)
- Clear local data: Delete your game progress through browser settings
To exercise your rights:
Use the feedback form on our website to request removal of stored scores, messages or account information. Include a challenge link or your public alias so we can locate the records. Clearing browser storage only removes local copies.
Children's Privacy
Our reaction time test is suitable for all ages. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us through our feedback form.
Changes to This Policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
