Privacy Policy

Last updated: May 2025

1. Overview

KeyTester.io (“we”, “our”, or “the Site”) is a free online keyboard diagnostic tool. We are committed to protecting your privacy. This policy explains what information is collected, how it is used, and your rights.

2. Information We Collect

2a. Keyboard Test Data

When you use the keyboard tester, your keystrokes are processed entirely in your browser. Individual key codes are temporarily held in browser memory during testing and are never transmitted to our servers. No keylogger functionality exists.

2b. Anonymous Session Analytics

We may collect anonymised, non-personally identifiable session data (e.g., browser type, country, number of keys tested) to understand how the tool is used and to improve it. This data cannot be used to identify you.

2c. Cookies

We use essential cookies to maintain your session preferences (e.g., dark/light theme). If Google AdSense is enabled, Google may set third-party advertising cookies. See Section 5 for details.

3. How We Use Information

  • To operate and improve the keyboard testing tool
  • To display aggregate usage statistics (no personal data)
  • To serve relevant advertisements (if ads are enabled)
  • To prevent abuse and maintain service security

4. Data Sharing

We do not sell, rent, or trade your personal information to any third parties. Anonymised, aggregated analytics data may be reviewed internally to improve the site.

5. Google AdSense & Third-Party Advertising

KeyTester.io may display advertisements served by Google AdSense. Google, as a third-party vendor, uses cookies (including the DoubleClick cookie) to serve ads based on your prior visits to this website and other sites on the internet.

You may opt out of personalised advertising by visiting Google Ads Settings or by visiting www.aboutads.info.

Google's use of advertising cookies is governed by Google's Advertising Policies.

6. Children's Privacy (COPPA)

KeyTester.io is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has submitted personal information through this site, please contact us so we can delete it.

7. Data Security

We implement industry-standard security measures. Since individual keystroke data never leaves your browser, the risk of keystroke data interception is zero for the testing functionality.

8. Your Rights (GDPR)

If you are a resident of the European Economic Area (EEA), you have the right to access, correct, or delete any personal data we hold about you. Because we collect only anonymised data, there is typically no personal data to act upon. For questions, contact us at the address below.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated “Last updated” date. Continued use of the site after changes constitutes acceptance.
