This Privacy Policy explains how Math Game (the Android / iOS app — Android package com.oojohn.countcard, iOS bundle ID com.mrjc0509.countcard — the "App") collects, uses, and protects your information.

The App is intended for users aged 13 and older. It is not directed at children under 13, and we do not knowingly collect personal information from children under 13. Children under 13 can still play in solo/guest mode, which requires no account and stores game data only on the device. If you are a parent or guardian and believe your child has provided personal information without consent, please contact us at the email below and we will delete it promptly.
