1. Introduction

JHCapps ("we", "our", or "us") respects your privacy. This Privacy Policy explains our practices regarding the collection, use, and disclosure of your information when you use our mobile applications, including MindBox, MathBox, GridBox, ZenBox, and WordBox (collectively, the "Apps").

2. We Do Not Collect Personal Data

Our philosophy is simple: we build games for you to enjoy, not to harvest your data. We do not collect, store, share, or sell any personal information.

  • No account creation is required to play.
  • We do not track your location.
  • We do not access your contacts, photos, or camera.
  • All gameplay progress and high scores are saved locally on your device.

3. Third-Party Services

Our applications are built using the Expo and React Native frameworks. Apple (via the App Store) may collect anonymous crash reports and aggregate usage data if you have explicitly opted-in to share analytics with developers in your iOS device settings. This data is entirely anonymous and cannot be used to identify you.

4. Children's Privacy

Because our Apps do not collect any personal information, they are completely safe for children of all ages. We fully comply with the requirements of COPPA (Children's Online Privacy Protection Act).
