Frequently asked questions
Is this a clinical test?+
No. It is a reasoning estimate for entertainment and self-discovery. It does not replace an evaluation by a licensed psychologist and cannot be used for diagnosis.
How accurate is the result?+
We show an estimate with a 90% confidence interval. Results vary with sleep, attention, device and environment. Our norms are provisional and are being recalibrated with real data.
How much does it cost?+
The test and the result are free. The Full Report costs $9.90 and the Premium Pack costs $19.90. Both are one-time payments.
Is there a subscription or recurring charge?+
No. No purchase renews automatically. You pay once and that's it.
How do I get a refund?+
Within 7 days, use the “Request refund” link on your result page or email us. Full refund, no questions asked, to the original payment method.
What data do you keep?+
Your answers, your result and your email if you provide it. We don't sell data, and you can ask us to delete everything at any time.
Can I retake the test?+
Yes. Every attempt generates different questions. People usually score a bit higher on a retake just from practice, so for a comparable result we recommend waiting a few months.
Who can take it?+
Anyone aged 16 or older. People under 18 need a parent or guardian's consent to make purchases.
