Inputs stay in this tab and are not uploaded or saved automatically. Optional aggregate usage counts and coarse processing diagnostics are sent only after consent, without input content or filenames. Clearing or closing loses inputs; save needed outputs first.
Method and limits
Start a 30-second focused window. You see the buttons held, total clicks and double-clicks, the latest interval, and the wheel delta and mode (0 pixels, 1 lines, 2 pages). Losing focus, hiding the tab or the time running out clears it. Browser and OS settings influence the events; there is no hardware diagnosis and no pointer history. This is a local browser observation only: no hardware diagnosis and no universal accuracy. Nothing is stored, recorded or uploaded, and no private-data telemetry is sent. Stop or reset clears the session. Browser, OS or permissions may leave results UNKNOWN.

How can I check the current result?
Focus the pad, click and scroll on purpose, then reset. Check the held buttons and the total counts. The latest interval is not a measure of hardware latency.
