GambitWise terms of use

Last updated: 1 November 2026

These terms cover GambitWise: Learn Chess and Go ("the app"). The developer is dav3studios. The publisher is David Lee ("we", "us"). You buy and download the app through the Meta Horizon Store, so the Meta Terms of Service (https://www.meta.com/legal/terms/) and the Meta Horizon Store terms also apply. If these terms and Meta's terms disagree, Meta's terms win.

Using the app

• The app is for personal, family and classroom use on the headsets that the store lists as supported.
• You may not copy, sell or share the app, or take it apart to reuse its code or content, except where the law allows it.
• Meta's headsets are for ages 10 and up. Children aged 10 to 12 need a parent-managed Meta account, and a parent or teacher should set up the headset and stay nearby.

Health and safety

Read Meta's health and safety warnings (https://www.meta.com/legal/quest/health-and-safety-warnings/) before using the headset. Use the app in a clear space with the boundary on. Take regular breaks, and stop at once if anyone feels sick, dizzy or uncomfortable.

What the app teaches

We work hard to make everything in the app accurate. Every fact comes from a named source. If you find a mistake, please tell us at lee_hantae@msn.com and we will fix it in an update.

Updates

We may update the app to fix problems, correct facts or add content. The store installs updates. The app works without an internet connection.

Our responsibility

The app is provided as it is. Nothing in these terms limits any rights you have under consumer law, including the UK Consumer Rights Act 2015. If the app is faulty, contact us, or ask Meta for a refund under the Meta Horizon Store refund policy.
