🧩 Introduction

Welcome to Sudoku : Offline.

This Privacy Policy explains how our app handles user information. We are committed to protecting your privacy and ensuring that our app remains safe and suitable for all users, including children.

🔒 Information We Collect

We do not collect or store any personal or sensitive information such as names, email addresses, phone numbers, photos, contacts, or precise location.

However, the app collects basic, anonymous usage analytics to help improve gameplay and app experience. These events are categorized as App Interactions in Google Play Console.

Examples of collected interaction events include:

• New game started
• Continue game clicked
• Challenge mode opened
• 6×6 Sudoku opened
• Hint used
• Undo used
• Notes mode toggled
• Cell erased
• Rewarded or interstitial ad watched

These analytics events are:

• Anonymous and aggregated
• Not used for tracking across apps or websites
• Used only to improve the app

📊 Analytics & Device Identifiers

The app uses Firebase Analytics to record the anonymous app interaction events listed above.

• Firebase is configured to avoid collecting personalized analytics or demographic data.
• Firebase may collect a pseudonymous device identifier (e.g., Firebase Installation ID) to differentiate devices.
• Diagnostic data such as crash logs and performance reports may also be collected.

📢 Advertising

Our app displays ads provided by Google AdMob.

While we do not collect any data ourselves, AdMob may collect limited device information (such as advertising IDs) to display non-personalized, contextual ads and measure performance.

👶 Child-Directed Treatment (COPPA Compliance)

We have configured AdMob to display only child-safe, non-personalized ads using:

.setTagForChildDirectedTreatment(RequestConfiguration.TAG_FOR_CHILD_DIRECTED_TREATMENT_TRUE)

• Ads are suitable for children
• No personalized advertising
• Only contextual ads shown

🔗 Third-Party Services

The app may use the following third-party services:

• Google AdMob (for ads)
• Firebase Analytics (for anonymous usage analytics)

🛑 Data Retention & Deletion

Data Retention Policy: The App Interactions and Device Identifiers collected via Firebase Analytics are retained for a maximum period of 2 months from the date of collection, which is the shortest retention option offered by our analytics provider. After this period, the data is deleted.

🛡️ Data Security

No personal data is collected or stored. Anonymous analytics and diagnostic data are protected by Google's security infrastructure.

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated “Last updated” date.
