Terms of Use

What Chess 4 Math is

Chess 4 Math is a math-practice adventure for children in grades 3–4, currently offered as a free previewwhile we build it. Using the site or the demo means you're okay with the plain-language terms on this page.

Using the demo

The demo is free for personal, family, and classroom-preview use. There are no accounts and no logins. Please use the site as intended — for example, only submit your own email address to the Parent Preview form, and don't attempt to disrupt or misuse the site.

It's a preview — honestly

Chess 4 Math is under active development. Islands and activities may change, be reworked, or occasionally break. Your child's progress is stored only in the browser on your device and can be lost — for example when the browser session ends — so please don't rely on it being kept. The preview is provided as-is, and we can't promise uninterrupted availability or specific learning outcomes.

Our content

The artwork, characters, story, and activities are © 2026 Chess 4 Math, all rights reserved. Enjoy them in the app — please don't copy, redistribute, or resell them.

Email signup

The Parent Preview email list is described in our Privacy Policy, including how to unsubscribe or have your address removed.

Changes & contact

As the product grows we may update these terms; we'll change the date at the top when we do, and continuing to use the site after a change means you accept the updated terms. Questions: chess4math@gmail.com.
