The short version
TestMyReaction is a static browser app for testing your cognitive performance. We do not collect, store, or transmit any personal information. Your test scores never leave your device.
Information we collect
None. We do not require sign-up, do not ask for your name or email, and do not run analytics, tracking pixels, or advertising scripts.
Local storage
To remember your personal best and attempt history, we save your scores to your browser's localStorageunder keys prefixed with cerebra:. This data:
- Stays on your device.
- Is never sent to us or any third party.
- Can be deleted at any time from the test page's history panel, or by clearing your browser's site data.
Cookies
We do not set any cookies.
Third parties
The site is served over standard web hosting infrastructure, which may automatically log basic technical request data (such as IP address and user agent) in transient server logs for operational reasons. TestMyReaction itself does not collect, retain, or analyze this information.
Children
TestMyReaction does not knowingly collect information from children or anyone else, because it does not collect information at all.
Changes to this policy
If we change how the app handles data, we will update this page and the "Last updated" date above.
