Your data is yours
Only you see your result. You can download or delete everything whenever you want, and no test data ever goes to an advertising platform.

On this page
01Who sees your result
Only you, unless you choose to share it. The share link carries an opaque code, never the number in the address, and your IQ only appears on it if you choose to show it.
Anyone with the code can verify the certificate, and the verification page shows only the minimum: first name, last initial, date and range.
02What we store
Your test answers, the time spent on each question, your age group, your education and your email. When you buy, the order record. Card details stay with the payment processor, not with us. The name and CPF (Brazilian taxpayer ID) you enter at checkout go straight to the payment processor (Asaas, which requires them) and aren't stored here.
03What never goes to advertisers
No test data, such as your answers, IQ or age, goes to any advertising platform. TikTok and Meta measurement cookies only work if you accept them, and the cookie notice has "Accept" and "Decline" buttons of the same size, with nothing pre-checked. The site works the same if you don't respond.
04Research to improve the test
To recalibrate the questions and the age norms, we use pseudonymized answers: without your email, IP address or payment data. This option is on by default, and you can turn it off in the Account tab whenever you want.
05What you control
- Download everything we store about you, in the Account tab.
- Delete your account and data: this erases your result, history, email and share links, and cancels any active subscription.
- Turn email tips, the use of your answers in research and measurement cookies on or off.
- Request access, correction or portability through Contact, with the subject "Personal data".
06How the system protects you
No password
You log in with a link sent by email, valid for 20 minutes and single-use. There's no password to leak.
Scoring key on the server
The scoring key never reaches the browser during the test, and your IQ doesn't exist on the page until the report is unlocked.
Security headers
Pages are served with a content security policy and over HTTPS only.
Legal records kept separate
Payment records that the law requires us to keep stay for the legal period and are not used for anything else.
