This Privacy Policy describes how Sudoku Fun with Friends (“the App”) collects, uses, and shares information when you use it.

1) Information We Collect

1.1 Account & sign-in information

If you use online features (for example, leaderboards, cloud sync, or friend-related features), you may be asked to sign in. Depending on the sign-in method, we may collect and store:

• Account identifiers (for example, a user ID created by our authentication system or provided by Google/Apple).
• Email address:
  • For Email sign-in, we use your email to create and manage your account and to send sign-in or verification messages (OTP/magic link) and/or password reset messages.
  • For Sign in with Apple, you may use an Apple relay email address if you choose “Hide My Email.”
• Display name / nickname (if you set one, or if provided by the sign-in provider).

Passwords: If Email + password sign-in is enabled, passwords are handled securely by the authentication system and are not stored in plain text.

1.2 Gameplay & leaderboard data

We may store game-related data necessary to provide online features such as leaderboards and progress sync:

• Leaderboard entries (scores, completion times, ranks).
• Game progress and settings (e.g., difficulty, preferences).
• Basic gameplay statistics used for leaderboards or feature improvements.

Leaderboards may be provided via Apple Game Center and/or our backend services. If data is stored on our backend, it may be associated with your account identifier.

1.3 Automatically collected technical data (analytics, diagnostics, ads)

The App and/or integrated SDKs may automatically collect limited technical data such as:

• Device information (model, OS version, language, region, app version).
• Diagnostics and performance data (crash logs, error reports, performance metrics).
• Approximate location (derived from IP address; not precise GPS), where required for fraud prevention, analytics segmentation, or ads (depending on providers/settings).
• Identifiers such as device identifiers and/or advertising identifiers (where permitted) to serve and measure ads.
• Ad interaction data (impressions, clicks) and fraud/abuse signals.

2) How We Use Information

We use information to:

• Provide and operate the App (including sign-in, online features, and leaderboards).
• Create and maintain your account and authenticate you.
• Store and display leaderboard results.
• Improve stability and performance (crash/diagnostic analysis).
• Measure usage and improve features (analytics).
• Serve and measure advertisements (where ads are shown).
• Prevent fraud and abuse and maintain security.
• Respond to support requests.

3) Third-Party Services

The App may use third-party services/SDKs that process data under their own policies, including:

• Firebase Authentication (account creation and sign-in)
• Firebase Database / Firestore (storing game/leaderboard-related data where applicable)
• Firebase Analytics (usage analytics)
• Firebase Crashlytics (crash reporting)
• Google AdMob (ads, ad measurement, fraud prevention)
• Apple Game Center (leaderboards/achievements where enabled)

Please review the privacy policies of the relevant providers for details about their practices.

4) Tracking & Personalized Ads (iOS ATT)

On iOS, the App may request permission under Apple’s App Tracking Transparency (ATT) framework if needed for certain advertising functionality. You can choose Allow or Ask App Not to Track.

• If you choose not to allow tracking, ads may be less personalized.
• You can also adjust ad personalization and privacy settings in your device settings where available.

5) Data Sharing

We do not sell your personal information. We may share information with service providers only as needed to:

• Operate authentication and backend services (account, leaderboard, sync).
• Provide analytics and crash diagnostics.
• Serve and measure ads and prevent fraud.
• Comply with legal obligations and protect user safety and security.

6) Data Retention

• Account data is kept while your account is active or as needed to provide services.
• Leaderboard records may be retained to preserve rankings/history, unless deletion is requested where applicable.
• Analytics/diagnostics/ad data are retained according to the relevant provider’s retention policies.

7) Your choices & account deletion

You can request access, correction, or deletion of your account data by contacting us at help@pocemucka.com.

If the App provides account creation, it also provides an option to initiate account deletion from within the App’s settings (or a direct link to the deletion page), as required by platform policies.

We may need to verify account ownership before processing deletion requests to prevent unauthorized deletions.

8) Children’s Privacy

The App is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us at help@pocemucka.com.

9) Security

We use reasonable safeguards to protect information. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

10) International transfers

Providers may process data on servers located outside your country. Where applicable, they apply safeguards required by law and their policies.

11) Changes to this Privacy Policy

We may update this Privacy Policy from time to time. We will update the effective date above. Continued use of the App after changes means you accept the updated policy.
