Privacy Policy

This Privacy Policy describes how Amsunaris ("we", "us", "our") collects, uses, and protects information when you ("User", "you") use the Matixo mobile application ("App", "Game", "Service"). This policy is designed to comply with applicable privacy laws, including the Children's Online Privacy Protection Act (COPPA), the General Data Protection Regulation (GDPR), and the Google Play Families Program requirements.

Matixo is an educational math game designed for children aged 5 and older. We take children's privacy very seriously and have designed the App with privacy-by-default principles.

By using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If the User is a child, a parent or legal guardian must review this Privacy Policy before allowing the child to use the App.

1. Information We Collect

1.1 Information Stored Locally on the Device

The App stores the following data locally on your device only. This data is never transmitted to our servers or any third party:

This data is stored using a local SQLite database and SharedPreferences on the device. We do not collect, store, or have access to any of this information.

1.2 Information Collected Automatically

Firebase Analytics (by Google)

We use Firebase Analytics to understand how the App is used in aggregate. Firebase Analytics collects anonymous, non-personally-identifiable usage data, including:

• Game events: game starts, game completions, scores, coins earned, and session duration.
• Answer attempts: which math problems were attempted and whether answers were correct (no personal information is included).
• Technical data: device type, operating system version, app version, screen resolution, and general geographic region (country-level, derived from IP address by Google — the IP address itself is not stored by us).

Firebase Analytics does not collect:

• Names, email addresses, phone numbers, or physical addresses.
• Photos, videos, or audio recordings.
• Precise location data (GPS coordinates).
• Persistent personal identifiers linked to individual children.

Firebase Analytics is operated by Google. For information on how Google processes this data, please see:

• Google Privacy Policy
• Firebase Privacy and Security Documentation

Google AdMob (Advertisements)

The App may display advertisements provided by Google AdMob. When advertisements are displayed:

• For child-directed content, we configure AdMob to serve non-personalized, age-appropriate ads only, in compliance with COPPA and GDPR requirements.
• Personalized advertising is disabled for all users of this App.
• AdMob may collect limited technical information as necessary to serve ads, including:
• Device type and operating system version.
• Ad interaction data (e.g., whether an ad was viewed or clicked).
• Non-precise, IP-derived geographic information (country/region level).
