Privacy policy
No account, no uploads. Your results never leave your device.
What we store
Three small values in your browser's own localStorage: your light/dark theme choice, your language choice, and your screen-calibration profile. When you finish a run, the result summary is stored the same way so the stepper can show what you have already covered. None of it is transmitted anywhere.
What we do not do
No account, no sign-in, no advertising, no tracking pixel, no server-side log of your results. We use Cloudflare Web Analytics for basic anonymous traffic metrics. The page loads fonts from Google Fonts, which means Google sees the request for the font files — nothing about your test is attached to it.
Your control
Clearing site data in your browser removes everything. The reported results can also be downloaded as a plain-text file or copied, and you can simply not do that — nothing is kept on our side either way.
Children
The screener is intended for adults preparing for a driver-licence or CDL medical examination. It is not directed at children.
Changes and contact
