Your mouse events stay in the browser
Mouse Click Test reads pointer, click and wheel events in the page so the interface can show counters and intervals. Test events are used for the current session and are not uploaded as a device log.
No account or required tracking
All tests work without sign-up, extensions or downloads. We do not request your device name, serial number or files, and the tools do not require an analytics account or advertising profile.
Optional local mouse test history
The CPS test can save recent results in your browser's localStorage so the history page can compare and export them. The site keeps up to the latest 30 runs on that device; this data is not sent to our server. Use Clear history to remove it.
Reset and clear visible results
Use each Reset button to clear the visible event log and counters. Closing the page clears in-memory test state, while optional local history remains until you clear it in the history page or browser settings.
