Privacy policy

Last updated: October 2026

The short version

Our tests run entirely in your browser. We don't have accounts, we don't ask for your name or email to use the site, and your test inputs and results are never sent to us. If we show advertising, our advertising partners may use cookies as described below.

Information that stays on your device

• Test inputs. Clicks, key presses, controller inputs and timing measurements are processed by your browser and are not transmitted to us.
• Microphone and camera. The mic and webcam tests only use your microphone or camera after you press Start and your browser asks for permission. Audio and video are analysed in your browser and never sent to us. Recordings and photos you make stay on your device unless you download or share them yourself.
• Personal bests. Your best scores are saved in your browser's local storage on your device so you can see them next time. You can delete them by clearing this site's data in your browser settings.
• Shared results. When you share a result, the score is placed in the link or image you choose to share. We don't receive it unless someone opens that link, in which case the score is visible in the page address like any other web address.

Information collected automatically

Like nearly every website, our hosting provider (Google Firebase Hosting) processes technical information such as your IP address, browser type and the pages requested in order to deliver the site and keep it secure. This may be stored in server logs for a limited time.

Advertising and cookies

We may use Google AdSense to show ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the internet.

• You can opt out of personalised advertising by visiting Google Ads Settings.
• You can learn more about how Google uses data at How Google uses information from sites or apps that use its services.
• You can also opt out of some third-party vendors' use of cookies for personalised advertising at www.aboutads.info.

Visitors in the European Economic Area, the United Kingdom and Switzerland will be asked for consent before personalised advertising cookies are used, and can change their choice at any time.

Children

Our tests are suitable for a general audience. We don't knowingly collect personal information from children, and the tests themselves collect no personal information from anyone.

Your rights

Depending on where you live, you may have rights to access, correct or delete personal data held about you. Because we don't hold personal data from our tests, most requests will relate to advertising cookies, which you can control as described above. For anything else, see our contact page.

Changes

We may update this policy as the site changes. The date at the top shows when it was last revised.
