Terms of use

The ground rules for using the site, in plain language.

Last updated 23 August 2026

By using iq-test.io (“the site”), you agree to these terms. They are short and written in plain language; please read them.

What the site is

IQ Test offers a free online reasoning test and the explanatory pages around it. The result is an educational estimate, provided for self-interest and general insight. It is not a clinical, medical, psychological, or psychiatric assessment, and it is not a diagnosis. We repeat this across the site because it matters: decisions with real consequences should rest on a supervised assessment by a qualified professional, not on an online test. Our methodology explains exactly what the score measures and where its limits lie.

No professional advice

Nothing here is medical, psychological, legal, or career advice, and using the site creates no professional relationship between you and us. If you have concerns about your cognition, learning, or development, consult a licensed practitioner.

Access and acceptable use

The 33-question test and the score it produces are free, and always will be. Some features are paid, and are listed under paid access below. You can use the free part without an account; the paid part needs one, because it has to remember what you bought. We may change, suspend, or discontinue any part of the site at any time without notice. You agree not to misuse it: no attempting to disrupt or overload it, no scraping or automated harvesting of its content, no reverse-engineering it in order to clone it, and no unlawful use of any kind. The reasoning items and explanatory text are ours or our licensors’; the ICAR-derived items are used under their public-domain terms; you may not republish the site’s content as your own.

Your submissions

If you enter an email to unlock a result, you confirm it is a genuine address you are entitled to use. How we handle it is set out in the privacy policy, and the small files the test stores are listed in the cookie policy.

Third-party links and disclaimer

Some pages link to outside sources, such as research papers. We don’t control those sites and aren’t responsible for their content. The site itself is provided “as is,” without warranties of any kind, express or implied, including accuracy or fitness for a particular purpose. Results carry an inherent margin of error and may not reflect your performance on a different day or with a different instrument.

Limitation of liability

To the fullest extent the law allows, IQ Test is not liable for any loss arising from your use of, or reliance on, the site or its results. Where liability cannot be excluded, it is limited to the minimum the law permits.

The test itself and your score stay free. Payment unlocks the certificate carrying your name, the detailed breakdown of your answers with the explanation of each mistake, the three advanced tests, and the training exercises.

Two ways to pay. Monthly: $10 for the first month, then $30 each month until you cancel. One payment: $50, which does not expire and covers features we add later.

Payment is handled by Stripe. We never see or store your card details. Prices are in US dollars; your bank may apply its own conversion or fees, which are outside our control.

Cancelling and refunds

Monthly: cancel at any time and access continues to the end of the period you have already paid for. We do not charge again after a cancellation, and we do not refund a period that has already begun.

One payment: if it is not what you expected, write to us within 60 days of the purchase and we will refund it in full. Refunds withdraw the paid features; anything already issued to you, such as a certificate, remains yours.

If a renewal fails because your card was declined, your access runs to the end of the period you paid for while the payment is retried. We do not cut it off the moment a bank says no.

Nothing here limits rights you have under the consumer law of your own country, including any statutory right to withdraw from a distance purchase.

Changes and governing law

We may update these terms; the current version is dated above, and continued use after a change means you accept the revised version. These terms are governed by the laws applicable to the operator of IQ Test, and any dispute will be handled by the courts holding proper jurisdiction over it.
