Terms of Service

Neural Mastery is a free educational site, built and maintained by one person. These terms are intentionally simple, matching what this actually is — not a template written for a company with a legal department.

The service

The site is free to use, with or without a Google sign-in. Signing in adds cross-device sync for your progress, points, and streak, and a spot on the leaderboard — it isn't required to read any content or run any practice problem.

No warranty

The site is provided as-is, with no warranty of any kind. Content may contain errors — if you find one, please report it (see the About page). We make no guarantee the site will be available at any given time, or that your data will never be lost, though we have no intention of losing it.

Your conduct

Don't attempt to abuse, disrupt, or gain unauthorized access to the site or its backing services (Firebase Authentication, Firestore, Analytics). Practice-problem code runs entirely in your own browser (via Pyodide), so it can't affect anyone but you.

Changes

These terms, the site's content, and its features may change at any time — this is an actively developed project, not a finished, frozen product. Material changes to what data is collected will be reflected in the Privacy Policy.
