Privacy Policy

This site is a reference tool, not a data-collection platform. Every number, factor, prime-check, and calculator page here performs a mathematical computation using the values you enter or request — none of that input needs to be, or is, stored against your identity. Page views may be measured in aggregate, anonymized form (through standard analytics) to understand which pages are useful and which need improvement, without tracking you personally across sessions.

If a contact form submission includes your email address, that address is used solely to respond to your message and is not sold, shared, or added to a marketing list without your separate, explicit consent. Any future purchase (such as the Math Practice Pack) is processed through a third-party payment provider, which handles payment details directly — this site never stores your card information itself.

Cookies, where used, are limited to what’s functionally necessary (such as remembering a preference) or to standard, privacy-respecting analytics. This policy may be updated as the site’s features change; material changes will be reflected here with an updated date.
