Math Fury ("the App") is a children's educational math game developed by Alexander Klaas ("we," "us," "our"). This Privacy Policy describes our practices regarding the collection, use, and disclosure of information through the App.
Summary. Math Fury does not collect any personal information. The App works entirely offline, contains no advertising, no in-app purchases, and no third-party SDKs. Your child's gameplay data stays on the device.
Math Fury is designed for children ages 5–10. We are committed to complying with the Children's Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR) including Article 8 (children's consent), and Apple's App Store Review Guidelines for the Kids Category (Guideline 1.3 and 5.1.4).
We do not collect, store, transmit, or share any personal information from users, including children. Specifically:
The App stores gameplay data (progress, statistics, achievements) locally on the user's device using Apple's SwiftData framework. This data:
The App does not use any third-party services, SDKs, or APIs. The App uses only Apple's system frameworks (SwiftUI, SpriteKit, AVFoundation, SwiftData).
The App does not contain any advertising — no banner ads, no interstitials, no rewarded ads, no sponsored content, no cross-promotion to other apps.
The App does not contain any in-app purchases. Math Fury is available for a one-time purchase on the App Store; after purchase, all content is unlocked.
The App does not contain any external links that would take a child out of the App (no web links, no social media buttons, no links to other apps or stores). This is in compliance with Apple's Kids Category requirements.

For residents of the European Economic Area, we note that because Math Fury does not collect or process any personal data, most GDPR rights (access, rectification, erasure, portability) do not apply — there is no data to access or erase beyond what is already stored locally on your device and fully under your control. The lawful basis for any local data storage is your device's own operation.
We do not collect, sell, or share personal information of California residents, including children. There is no data to disclose or delete on request.
We may update this Privacy Policy from time to time. We will notify users of any material changes by updating the "Last Updated" date at the top of this document. Continued use of Math Fury after changes are posted constitutes acceptance of the updated Privacy Policy.
