ReactionTestPro

Terms of Use

By using this site you agree to these terms. They are deliberately short and readable — please read the medical section in particular.

Last updated:

Not medical advice

Nothing on ReactionTestPro is medical advice, and no test here can diagnose any condition. The ADHD screening, vision, colour vision and hearing tests are educational self-assessment tools that run on ordinary consumer hardware. They are not calibrated clinical instruments, they are not administered by a clinician, and their results have no diagnostic value.

Only a qualified healthcare professional can diagnose ADHD, a vision or colour vision deficiency, hearing loss, or any other condition. Never disregard professional medical advice, delay seeking it, or start or stop any treatment because of a result you saw here. If you have a health concern, consult a doctor, optometrist or audiologist.

If you think you may be experiencing a medical emergency, contact your local emergency services immediately.

1. Who these terms are with

These terms are an agreement between you and [PLACEHOLDER: your full name or registered business entity], the operator of ReactionTestPro (https://reactiontestpro.com). If you do not accept them, please do not use the site.

2. What the site is

ReactionTestPro offers free, browser-based tests of reaction time and related cognitive and sensory abilities. No account is required and no payment is taken. The tests are provided for personal interest, curiosity and self-comparison.

Results depend heavily on factors we do not control: your screen's refresh rate and input latency, your browser, your device, your headphones or speakers, ambient light and noise, fatigue, caffeine and attention. Two people with identical ability can get different numbers on different hardware. Treat every figure as an approximation, not a measurement.

3. Acceptable use

You agree not to:

  • use the site for any unlawful purpose, or in a way that could damage or overload it;
  • attempt to gain unauthorised access to the site, its server or any connected system;
  • scrape, mirror or systematically extract the site's content for republication;
  • present results from this site as clinical, diagnostic or officially certified;
  • remove, obscure or misrepresent any disclaimer shown alongside a test.

4. Intellectual property

The site's design, code, written content and original graphics belong to the operator and are protected by copyright. You may link to any page freely, and quote short passages with attribution. You may not reproduce substantial portions or republish the tests as your own.

Third-party names, standards and instruments referred to on the site — for example established screening scales, chart designs or motorsport terminology — remain the property of their respective owners. They are named only to describe what a test is based on. Their mention does not imply any affiliation with, endorsement by, or licence from those owners, and this site is not affiliated with or endorsed by any of them.

5. Availability

The site is provided as-is and as-available. We may change, suspend or discontinue any test or the entire site at any time, without notice. We do not guarantee uninterrupted access or that any result you have saved locally will remain available.

6. Disclaimer of warranties and limitation of liability

To the fullest extent permitted by law, the site is provided without warranties of any kind, express or implied, including any warranty of accuracy, fitness for a particular purpose, or non-infringement. We do not warrant that any result is accurate, meaningful, or comparable to any clinical or professional measurement.

To the fullest extent permitted by law, the operator is not liable for any indirect, incidental or consequential loss arising from your use of the site or from any decision you take on the basis of a result. Nothing in these terms limits liability that cannot lawfully be limited, including liability for death or personal injury caused by negligence, or for fraud.

7. Privacy

Your data is covered by our Privacy Policy. In short: tests run in your browser, your answers are never sent to a server, and the site sets no cookies and runs no analytics.

8. Changes and governing law

We may update these terms; the date at the top will change when we do, and continued use after an update means you accept the revised terms.

These terms are governed by the laws of [PLACEHOLDER: country / state whose law governs this site], and any dispute will be subject to the courts of that jurisdiction.
