Terms of use

Last updated: 25 October 2026

These terms apply to everyone who uses iQ at lorrank.com ("the site", "we", "us"). By using the site, you agree to them. If you don't agree, please don't use the site.

Using the site

• The courses, lessons and IQ tests are free for personal, educational use.
• You may share links to any page. Please don't copy whole lessons, diagrams or tests to publish elsewhere without our permission.
• Don't misuse the site: no attempts to break it, overload it, collect other users' data, or send spam through the contact form.

Accounts

• You don't need an account to read lessons or take the IQ test. An account lets you track your progress.
• Keep your password private. You're responsible for activity on your account.
• We may suspend accounts that break these terms.

Educational content, not professional advice

• Our lessons are general educational information. We work hard to keep them accurate, but we can't guarantee they are complete or up to date.
• Health lessons are not medical advice. If someone is sick, see a health worker.
• Money and economics lessons are not financial advice. Decisions about your money are your own.
• The iQ test is a self-assessment for practice and interest. It is not a clinically validated IQ test.

Donations

• Donations are voluntary, one-off payments processed by Stripe. They help pay for running the site and don't buy any extra access or services.
• If you donated by mistake, contact us within 14 days and we'll do our best to arrange a refund.

Advertising and links

The site may show advertising, including ads from Google, to help keep it free. We are not responsible for the content of ads or of other websites we link to. How advertising uses cookies is explained in our privacy policy.

Our liability

The site is provided "as is". To the extent allowed by law, we are not liable for any loss arising from using the site or relying on its content. Nothing in these terms limits any rights you have under consumer law that can't be excluded.

Changes

We may update these terms. The date at the top shows when they last changed.
