About How The Horsey Moves

What is this?

How The Horsey Moves is a free, open-source chess trainer designed for young students in classroom settings. It teaches how each chess piece moves through interactive puzzles, board setup exercises, checkmate patterns, tactics, endings, openings, model games, blindfold training, and play against the computer.

There are no accounts, no ads, no chat, no memberships, and no data collection. Everything runs in your browser. It will always be free.

Privacy & Student Safety

This site is designed with student privacy as a first principle:

  • No personal information is collected — no names, emails, or accounts
  • No server-side data storage — all progress is saved locally in the student's browser using localStorage
  • No cookies for tracking or analytics
  • No third-party trackers, ads, or analytics
  • No chat or social features
  • No external API calls — the app runs entirely client-side

Because no personal information is collected from children (or anyone else), COPPA (Children's Online Privacy Protection Act) obligations regarding parental consent do not apply. The site does not collect, use, or disclose personal information from users of any age.

The site is hosted on Vercel, which may collect standard web server logs (IP addresses, request timestamps) as part of normal hosting operations. These logs are not accessible to us and are governed by Vercel's Privacy Policy.
