Terms of Service

Service

YZR provides an estimated IQ from 40 puzzles, for entertainment and curiosity. This is an estimate on a standard scale (mean 100, standard deviation 15). It was not measured on a sample of YZR users. The margin is provisional, about ±8 points, and may be wider. It is not a clinical or diagnostic test. The number is calculated from the share of puzzles you answered correctly, using a fixed formula. It has not been checked against other IQ tests. Any summary issued here is issued by the platform. It is for entertainment and curiosity. It has no clinical, professional, or academic validity, and it is not an official IQ certificate. It is not a substitute for professional evaluation.

Account termination

We may close an account that breaks these terms or that we cannot keep secure. You may stop using the account and ask us to delete it, subject to the retention periods on the privacy page.

Changes

If we change these terms, we post the new text on this page. A price you already accepted stays the text stored with that consent. Text version 2026-10-07-terms-v7-closed. This page is subject to legal review.

Liability

To the extent the law allows, liability for this estimate is limited to the amount you paid us in the 12 months before the claim. This does not limit rights that mandatory consumer law does not let us limit. This sentence is subject to legal review.

Governing law and venue

These terms do not name a governing law or a court. Mandatory consumer rights in your country still apply. This section is subject to legal review.
