Privacy Policy

Last updated: October 12, 2026

This policy explains what information 800 Math Club ("we") collects on this website, why, and what you can do about it. Contact: hello@800mathclub.com.

What we collect

• Your email address, when you choose to unlock your diagnostic report or join early access.
• Your diagnostic summary, sent with your email: number of correct answers, score estimate, your biggest point leak, and which questions you got right, wrong or left blank. If the signup form asks for your current SAT Math score, we receive that too.
• Anonymous usage statistics, such as page views and button clicks, collected with Plausible Analytics. Plausible does not use cookies and does not collect personal data; visits cannot be tied to you.

Your answers and timer while you take the diagnostic are stored only in your own browser, so you can continue after a reload. They are not sent to us unless you submit your email.

How we use it

• To show your full report and to tell you when the full program opens.
• To understand which parts of the site and diagnostic are useful, and to improve them.

We do not sell your information or share it for advertising.

Services we use

• Tally (tally.so) receives and stores the signup form.
• Plausible (plausible.io) provides cookie-free analytics.
• Our website host serves the pages and keeps standard server logs.
• Google Fonts delivers the typefaces; your browser requests them from Google.

Legal basis and your choices

We process your email based on your consent. You can withdraw it at any time: use the unsubscribe link in any email, or write to us and we will delete your information. You can also ask for a copy of what we hold about you, or ask us to correct it. If you are in the EU or UK, you may complain to your data protection authority.

How long we keep it

We keep your email and diagnostic summary until you unsubscribe or ask us to delete them, and in any case no longer than 24 months after our last email to you.

Students and age

This site is meant for high school students preparing for the SAT and their parents. Do not submit your email if you are under 13. If you are under 16, or under the age of digital consent where you live, ask a parent or guardian before you submit. If you believe a child under 13 has given us their email, write to us and we will delete it.

Changes

If we change this policy, we will update the date above. For significant changes, we will tell people on our email list.
