Question 1

Is it really free?

Accepted Answer

Yes. Taking the 30 questions, getting your estimated IQ and top percentile — all free. Only the detailed PDF report (per-category scores, age-group comparison, all 30 explanations) is paid at $3.70.

Question 2

How accurate is the score?

Accepted Answer

It's an estimate that maps your correct-answer rate onto a normal distribution (mean 100, SD 15) — the same approach used in psychometrics. Not a clinical diagnosis; results can vary ±5–10 with mood and conditions.

Question 3

How do I pay?

Accepted Answer

Via Lemon Squeezy (global payment processor). Card, Apple Pay, KakaoPay, and more. Digital products are non-refundable once delivered.

Question 4

When do I get the report?

Accepted Answer

Immediately after payment — the PDF is auto-emailed to the address you provide. If it hasn't arrived in 5 minutes, check your spam folder.

Question 5

How is my data handled?

Accepted Answer

Your email is used only to deliver the report and is deleted after 90 days. Test responses are stored against anonymous session IDs and aren't linked to your identity.

Question 6

Can I take the test more than once?

Accepted Answer

There's no hard limit, but for accuracy we recommend waiting 24 hours between attempts. Scores tend to cluster within a narrow band when conditions match.

Question 7

Is the paid report a one-time purchase?

Accepted Answer

Yes — once paid, that session's result page stays unlocked forever. Bookmark the URL or save the emailed PDF for permanent access.

Question 8

Do I need to register a business to accept payments?

Accepted Answer

Operator note — Lemon Squeezy is a Merchant of Record, so no business registration is required to launch. Tax/VAT handling is automatic.

Question 9

Can I compare results with a friend?

Accepted Answer

Yes — after unlocking, the result page has a 'Create compare link' card. Paste your friend's session UUID and you'll get a side-by-side compare page.

Question 10

Why can't I go back to previous questions?

Accepted Answer

We measure response time per question; allowing review would dilute the signal. A strict 60s-per-question flow matches the standard IQ assessment conditions.
