Terms of use
Last updated:
Use these tools for personal practice and basic checks of your own input devices. Do not use them to collect another person’s input or interfere with a service.
Measurements are estimates based on events available to the page. They are not professional hardware certification, a guarantee of device health, or a standardized score across languages and devices.
The service is provided as available, without a promise of uninterrupted operation. To the extent permitted by applicable law, we are not responsible for losses resulting from reliance on these measurements. Nothing here limits rights that cannot legally be excluded.
You may stop using the tools at any time. For questions about these terms, contact [email protected].
