King Sudoku by Ammaneh

Last updated: April 26, 2026

This Privacy Policy describes how Ammaneh ("we", "us", or "our") collects, uses, and shares information about you when you use our King Sudoku mobile application (the "App"). King Sudoku is a paid/subscription app and does not display third-party advertisements inside the App.

Information We Collect

Information You Provide

• Account Information: When you create an account, we collect your email address, display name, and authentication credentials (via Google Sign-In or Sign in with Apple).
• Contact Information: When you contact us for support, we collect your name, email address, and the content of your message.

Information Collected Automatically

• Game Data: We collect your game statistics, including wins, losses, best times, streaks, and saved game progress.
• Device Information: We may collect information about your device, including device type, operating system, app version, language, and unique device identifiers.
• Advertising Identifier (IDFA): On iOS, we only access the Identifier for Advertisers (IDFA) if you grant permission via the Apple App Tracking Transparency prompt. We use this identifier solely to measure the effectiveness of our own marketing campaigns (see "App Tracking Transparency" below). If you decline, no IDFA is collected.
• Usage Data: We collect information about how you use the App, including features accessed, time spent in the App, and in-app events (e.g., levels completed, purchases).
• Crash and Diagnostic Data: We collect crash reports and performance data to identify and fix bugs.

Purchase Information

When you make in-app purchases, payment processing is handled by Apple (App Store), Google (Play Store), or Stripe (web). We receive confirmation of purchases (transaction ID, product ID, price, currency, purchase date) via RevenueCat but do not directly collect or store your payment card information.

App Tracking Transparency (iOS)

On iOS devices, we present the Apple App Tracking Transparency prompt to ask for your permission before linking data collected from this App with data from other companies' apps and websites for marketing measurement purposes.

If you grant permission, your device's advertising identifier (IDFA) is shared with our mobile measurement partner, AppsFlyer, so that we can determine which marketing campaigns brought you to King Sudoku and measure their effectiveness. We do not use this data to show you ads inside the App, and we do not sell this data to advertisers.

If you decline, no IDFA is collected and no cross-app tracking occurs. You can change your choice at any time in iOS Settings → Privacy & Security → Tracking.

How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the App
• Create and manage your account
• Sync your game progress across devices
• Process in-app purchases and manage your coin balance
• Respond to your comments, questions, and support requests
• Send you technical notices and security alerts
• Analyze usage patterns to improve user experience
• Detect, prevent, and address technical issues

Data Storage and Security

We use Firebase, a Google Cloud service, to store and process your data. Your data is stored securely using industry-standard encryption and security practices. We implement appropriate technical and organizational measures to protect your personal information against unauthorized access, alteration, disclosure, or destruction.

Third-Party Service Providers

We share limited data with the following third-party service providers, each acting on our behalf for specific purposes:

• Firebase / Google Cloud (Google LLC): Authentication, cloud database (Firestore), hosting, push notifications, analytics, and crash reporting (Crashlytics). Data shared: account ID, email, game data, device information, usage events, crash logs.
• RevenueCat, Inc.: Subscription and in-app purchase management, entitlement validation, and purchase fraud prevention. Data shared: app user ID, device identifiers, purchase history, subscription status.
• AppsFlyer Ltd.: Mobile measurement partner used solely for marketing campaign attribution (measuring which of our marketing campaigns drove App installs). Data shared: device identifiers (including IDFA on iOS only with your ATT consent), install events, in-app events, and purchase events. AppsFlyer may share aggregated or campaign-level data with the ad networks running our campaigns (e.g., Meta, Google, TikTok).
• Google Sign-In and Sign in with Apple: Authentication providers used when you choose to sign in with these services. Data shared with us is limited to your email address, display name, and authentication token.
• Stripe, Inc.: Payment processing for web-based subscriptions. Stripe receives the information necessary to process the payment.

We do not sell your personal information. We may also disclose information when required by law, in response to valid legal requests, or in connection with a merger, acquisition, or sale of assets.

Tracking and Advertising

King Sudoku does not display third-party advertisements. We use device and user identifiers, with your consent where required, only to:

• Measure which of our own marketing campaigns brought users to the App (via AppsFlyer);
• Understand how the App is used so we can improve it (via Firebase Analytics);
• Authenticate you, sync your progress, and validate purchases (via Firebase and RevenueCat).

Under Apple's App Tracking Transparency definition, our use of identifiers for marketing-campaign measurement constitutes "tracking," which is why we present the ATT prompt on iOS. You may decline this prompt without losing access to any App functionality.

Your Rights and Choices

You have the following rights regarding your personal information:

• Access: You can access your account information through the App's settings.
• Update: You can update your display name and other profile information in the App.
• Delete: You can request deletion of your account and associated data. Visit our account deletion page for instructions.
• Opt-out: You can opt out of promotional communications by following the unsubscribe instructions in those messages.
• Tracking (iOS): You can grant or revoke tracking permission at any time via iOS Settings → Privacy & Security → Tracking, or via Settings → King Sudoku.
• Analytics opt-out: On iOS and Android, you can limit ad tracking and reset your advertising identifier in your device settings.

Children's Privacy

The App is not directed to children under 13 years of age. We do not knowingly collect personal information from children under 13. If we learn that we have collected personal information from a child under 13, we will take steps to delete that information.

Data Retention

We retain your personal information for as long as your account is active or as needed to provide you services. If you request account deletion, we will delete your data within 30 days, except for:

• Purchase transaction records (retained for up to 7 years for financial compliance)
• Anonymized analytics data that cannot be linked back to you

International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence. These countries may have different data protection laws. We take appropriate safeguards to ensure your information remains protected.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date. You are advised to review this Privacy Policy periodically for any changes.
