What this site is

IQ Test Free (this domain) is an independent, free set of self-assessment cognitive quizzes: a standard IQ test, a harder Mensa-style practice test, and an IQ test for kids. It is not affiliated with Mensa International, any national Mensa society, any university, or any clinical testing organization. The scores reported use a standard, publicly documented scoring convention (see our IQ score chart), but none of these results are official credentials or clinical diagnoses.

Your answers and score never leave your browser

Every question, every option you click, and the final score calculation all run entirely as JavaScript in your own browser tab. There is no backend endpoint that receives your answers, no server-side transcript of which questions you got right or wrong, and no logging of your specific responses anywhere. Your estimated IQ, percentile and category breakdown are calculated entirely on your device from your in-browser answers and are shown to you and only you, on that same page.

Closing the tab, refreshing the page, or clicking "Retake the test" clears that in-memory result; nothing about your specific answers is stored anywhere, in your browser or otherwise, once you leave or restart the test.

Local storage: what is saved on your device

This site saves two small things to your browser's local storage (a small amount of data your browser keeps on your device between visits, not automatically sent to any server): a flag used by the feedback widget (described below) to avoid asking for a vote twice on the same device, and your light/dark theme choice, so the site remembers your preferred appearance the next time you visit. Your quiz answers and score are not saved this way; they exist only in the page's memory while you have the results screen open, described in the section above.

Analytics

If enabled, this site uses Cloudflare Web Analytics, a cookie-free analytics service. It does not set any tracking cookie, does not build a cross-site profile of visitors, and does not use any persistent device identifier. It reports aggregate figures only, such as page views and approximate visitor counts, without identifying individual visitors or recording any quiz answers, scores, or other tool-specific data. If analytics is not actively configured for this domain at the time you are reading this, the corresponding script simply does not load at all.

The feedback widget

Below each tool, a small "Was this tool helpful?" prompt lets you send an anonymous thumbs up or thumbs down. Clicking it sends only two pieces of information: which page you voted on, and which button you clicked. No cookie, IP address, device fingerprint, quiz answer, or score is stored alongside that vote. A note is saved in your browser's local storage purely to stop the prompt from asking again on the same device; that note contains no personal data.

The "Give feedback" link next to the vote buttons opens your own email client with a pre-filled address; nothing is sent unless you choose to write and send an email yourself.

Server requests and basic technical logs

Loading any web page necessarily involves your browser making requests to a server, in this case Cloudflare's infrastructure, which hosts this site. Like effectively every website, baseline connection information (such as IP address and request timestamp) passes through that infrastructure as a normal part of serving the page and is subject to Cloudflare's own standard operational logging, used for security and reliability rather than for tracking individual visitors on behalf of this site. This site does not separately collect, store, or review that information itself.

Third parties

This site does not sell, rent, or share visitor data with third parties, because it does not collect meaningful visitor data to begin with. The only third-party service in use is the optional, cookie-free analytics beacon described above, provided by Cloudflare as part of hosting this site. No advertising network, tracking pixel, or third-party script currently runs on this site. If that changes in the future, for example if a paid advertising slot is added, this page will be updated to reflect it and to name the specific network involved.

Children's privacy

Our IQ test for kids page is written for children but does not collect any personal information from any visitor, regardless of age: there is no account system, no name or age field, no email collection, and quiz answers never leave the browser, exactly as described above for every tool on this site.

Your choices

You can clear the small feedback-vote flag and theme choice described above at any time by clearing your browser's site data for this domain through your browser's own settings. Because no account exists, there is no login to delete and no server-side profile to request removal of; your browser's local storage holds only those two small, non-identifying items.

Changes to this policy

If the data practices described on this page change, for example if a new feature starts collecting information that was not previously collected, this page will be updated to describe the change plainly, in the same style as the rest of this policy, rather than moved or hidden behind a version history.
