Master of Codes

1. Overview & Scope

Welcome to Master of Codes ("we", "our", or "the App"). We are committed to upholding the highest standards of user privacy, digital security, and transparency. This Privacy Policy explains our data handling practices across the application, adhering to Apple App Store Review Guidelines, Google Play Developer Policies, the General Data Protection Regulation (GDPR), the UK GDPR, and the California Consumer Privacy Act (CCPA/CPRA).

By installing, accessing, or playing Master of Codes, you acknowledge and agree to the practices outlined in this Privacy Policy.

2. Information We Do NOT Collect

To protect your privacy by design, Master of Codes does NOT require user registration, account sign-ups, or social logins. Specifically:

• No Personal Identifiers: We do not ask for or store your full name, physical address, email address, or phone number.
• No Financial or Credit Card Data: All financial transactions are processed directly by Apple Inc. or Google LLC. We never receive or store your credit card or bank credentials.
• No Push Notifications or Tracking: The application does not send push notifications, and does not request or collect push notification permissions or device notification tokens.
• No Cloud Account Database: We do not operate a remote user profile database that links gameplay sessions to real-world personal identities.

3. Local Data Storage (SQLite & Secure Storage)

All your gameplay records, code-breaking history, hints used, unlocked trophies, custom theme colors, sound preferences, and offline level stats are stored strictly locally on your device using an embedded SQLite database and encrypted local storage (SharedPreferences / Flutter Secure Storage).

• Your save data never leaves your device and is not uploaded to external servers.
• You retain full ownership of your data. Deleting the application or clearing the application data from your system settings permanently erases all local database records.

4. In-App Purchases ("Remove Ads"), RevenueCat & Store Billing

Master of Codes offers an optional, one-time Non-Consumable In-App Purchase ("Remove Ads") that permanently disables third-party advertising in the app.

5. Advertising (Google AdMob)

To keep the free tier of Master of Codes available to all players, we display advertisements via Google AdMob. Once the "Remove Ads" in-app purchase is completed, all ad calls are permanently disabled.

6. Diagnostics, Analytics & Stability (Firebase Crashlytics & Analytics)

To identify software bugs, prevent crashes, and optimize game performance across various device models, we utilize Firebase Crashlytics and Firebase Analytics (provided by Google LLC).

Information Collected in Diagnostics:

• Anonymous stack traces, crash logs, and timestamps of errors.
• Device hardware specifications, operating system version, and battery / memory state during an incident.
• Aggregated usage metrics (e.g. game session duration, general level completion rates, screen navigation).

Diagnostic data is strictly aggregated and cannot be used to determine your real-world identity.

7. Third-Party Service Providers

Below is a summary of the reputable third-party service providers integrated into Master of Codes, along with links to their privacy policies:

8. Data Retention & Deletion Rights

Because we do not maintain centralized user databases, you have immediate control over your data:

• Local Data: You can completely delete all local game data, trophies, and records by uninstalling the application from your device.
• Advertising Identifiers: You can reset or limit your advertising identifier via iOS Settings (Privacy & Security → Tracking) or Android Settings (Google → Ads).

9. Your Rights (EEA, UK & California Residents)

Depending on your jurisdiction (e.g. GDPR, UK GDPR, California CCPA/CPRA), you have rights regarding your data:

• The right to know what technical information is processed by integrated diagnostic SDKs.
• The right to opt-out of personalized advertising and tracking.
• The right to non-discrimination for exercising your privacy rights.

Since we do not store personal account credentials, you can manage your advertising choices via Google Ad Center or by reaching out to us directly.

10. Children's Privacy (COPPA & Global Standards)

Master of Codes is an all-ages logic puzzle game. We do not knowingly collect, request, or solicit personal information from children under the age of 13 (or 16 where applicable by law). All advertising served in family-directed configurations is served as contextual and non-personalized in compliance with the Children's Online Privacy Protection Act (COPPA).

11. International Data Transfers

Third-party service providers (such as Google, Apple, and RevenueCat) may operate servers and store diagnostic or transaction validation tokens in the United States and other global regions. These providers adhere to recognized data transfer frameworks and standard contractual clauses to safeguard your information.

12. Changes to This Privacy Policy

We may revise this Privacy Policy periodically to reflect app enhancements, regulatory updates, or changes in store requirements. Any revisions will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
