Everything runs in your browser
All tests on ClickStorm (CPS tests, the reaction time test, the aim trainer, the spacebar counter and the rest) run entirely client-side in your browser. Your clicks, keypresses and scores are processed on your own device and are never sent to a server.
Your personal bests are stored in your browser's localStorage so you can try to beat them on a later visit. That data stays on your device. You can remove it at any time by clearing your browser's site data for this site.
No accounts, no tracking cookies
The site has no user accounts, no sign-up forms and no advertising or tracking cookies. We do not build profiles of visitors and we do not sell or share any data, because we do not collect any.
Hosting
The site is hosted on Vercel. Like any web host, Vercel processes standard technical request data (such as your IP address) to deliver the pages and keep the service secure. See the Vercel privacy policy for details.
