Terms
Terms of Service
Effective date: June 10, 2026
These terms apply to the free browser-based keyboard latency tester, chatter test, ghosting tester, and report export features on Keyboard Latency Tester.
Service scope
Keyboard Latency Tester provides browser-based keyboard diagnostics for latency, chatter, double typing, ghosting, key coverage, and local report exports.
No lab-grade guarantee
Browser timing is useful for comparison and troubleshooting, but it is not a certified physical switch-to-screen measurement. Results can vary by browser, operating system, hardware, wireless mode, USB hub, and background load.
Your responsibility
Use the diagnostic results responsibly. Do not rely on this free tool as the only basis for safety-critical, warranty, legal, or high-value purchasing decisions.
Third-party services
Analytics, advertising, hosting, and security providers may have their own terms when enabled. Their terms may also apply to your use of the site.
Changes
We may update the site, these terms, diagnostic logic, advertising placements, and available features over time.
