About IQ Test Free Online: Who We Are
We built the IQ test platform we always wished existed — one that is completely free, transparent about its methodology, free of deceptive paywalls, and built with strict on-device privacy.
Fixing the Broken World of Online IQ Tests
Most "free" IQ test sites follow an exploitative pattern: they promise a free assessment, make you spend 30 minutes answering questions, and then hit you with a $19.99 paywall right before showing your results.
- ✕Paywall at the end: Demands credit card info after you invest 25 minutes.
- ✕Deceptive score inflation: Hands everyone 135+ scores to sell premium certificates.
- ✕Aggressive test ads: Popups and banner ads that distract during timed questions.
- ✕Data harvesting: Collects your email and phone number for third-party marketing.
- ✓100% Free results: Complete score, percentile, and 5-domain profile are instantly accessible.
- ✓Transparent scoring: Percentile based on the standard normal distribution (mean 100, SD 15), documented on our methodology page.
- ✓Zero ads during test: A clean, distraction-free environment while you solve questions.
- ✓Zero server tracking: All test responses are stored exclusively in your browser's localStorage.
What We Are Not
We pride ourselves on what we refuse to do. Clear boundaries are the foundation of authentic cognitive tools:
Not a Clinical Diagnostic Service
Our assessment is an online screener for educational practice and baseline estimation. It is not a clinical psychological instrument and cannot replace clinical batteries (WAIS-V, Stanford-Binet).
No Manufactured "Certifications"
We do not claim our results are "Official State Certified" or "IIF Approved." We reject manufactured badges designed to trick users into purchasing worthless PDF diplomas.
No Flattery Score Inflation
We never boost user scores artificially to generate social shares. Your estimate comes straight from the documented scoring model (a normal distribution with mean 100 and SD 15).
No Subscription Traps
Everything on this platform is completely free. We have no recurring monthly billing, hidden recurring fees, or credit card collection.
Not a Data Broker
We never collect, store, package, or sell user cognitive performance. Your data never touches a remote server database.
Our Core Values
The principles that guide every decision we make regarding question design, scoring, and user experience:
Radical Transparency
We publish our complete scoring formulas, standard deviations, domain question breakdowns, and psychometric limitations openly on our Methodology page.
Truly Free Access
No paywalls. Your complete results, including the overall IQ estimate, its percentile on a normal distribution, domain strengths and question explanations, are free to explore.
Privacy by Design
All assessment results live on your device. There are no user accounts and we have no access to your individual answers. We use Google Analytics only for aggregate traffic statistics; see our privacy policy.
Educational Growth
Intelligence is not a static ceiling. Every question features full logical explanations so you can understand pattern structures and improve your analytical thinking.
The Person Behind the Test
IQ Test Free Online is an independent project. It is not affiliated with Mensa, test publishers or any clinical organization.
