Privacy Policy
Last updated: March 17, 2026
Maastarji ("we," "us," or "our") operates the Maastarji website at maastarji.com and associated mobile applications (the "Services"). This Privacy Policy explains how we collect, use, and protect your information when you use our Services.
We take your privacy seriously, especially because our Services are designed for children and families. Please read this policy carefully.
Children's Privacy (COPPA & GDPR-K)
Our Services are designed for educational use by children under the supervision of parents and educators. We take the following measures to protect children's privacy:
- We do not require account registration or the collection of any personal information to use our games, books, or learning resources.
- We do not knowingly collect personal information from children under 13.
- Game progress and settings are stored locally on your device only (via localStorage/sessionStorage) and are never transmitted to our servers.
- We do not display third-party advertisements.
- We do not include in-app purchases or any monetization within our games.
Information We Collect
Analytics Data
We use Firebase Analytics to understand how our Services are used. This collects aggregated, anonymized data such as which pages are visited and which games are played. This data does not identify individual users. Analytics are only active in our production environment. You can opt out by visiting maastarji.com?notrack=true.
Device Storage (Local Only)
Our apps and games store the following data on your device only, never on our servers:
- •Game preferences and settings (e.g., Kid Mode on/off)
- •Quiz session progress (cleared when the session ends)
- •Analytics opt-out preference
Newsletter (Optional)
If you voluntarily subscribe to our newsletter via Substack, your email address is collected and managed by Substack under their own Privacy Policy. We do not collect or store email addresses directly.
How We Use Information
We use the limited data we collect to:
- •Understand which learning resources are most helpful to families
- •Improve the quality and content of our educational materials
- •Ensure our games and features work correctly
We do not sell, rent, or share your data with third parties for marketing purposes.
Third-Party Services
We use a small number of trusted third-party services to operate our platform:
| Service | Purpose | Data Shared |
|---|---|---|
| Cloudflare Pages | Website hosting and CDN | Standard web request logs (IP, user agent) |
| Firebase Analytics | Anonymous usage analytics | Aggregated, anonymized event data |
| Substack | Optional newsletter | Email address (only if you subscribe) |
Data Security
Our Services are delivered over HTTPS. Since we do not collect or store personal information on our servers, the risk of a data breach affecting your personal information is minimal. Game data stored locally on your device is protected by your device's own security controls.
Your Rights
You have the right to:
- •Opt out of analytics — Visit maastarji.com?notrack=true at any time
- •Clear local data — Clear your browser or app storage at any time through your device settings
- •Contact us — Reach out with any privacy questions or requests
If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately and we will take steps to remove it.
Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Continued use of our Services after changes constitutes acceptance of the updated policy.
