Unified Privacy Policy

Welcome to illumina Software ("we", "our", or "us"). We design and publish high-quality tabletop, puzzle, and strategic mobile games. Your privacy is paramount to us. This Unified Privacy Policy explains how our titles handle, protect, and process user data across our entire mobile portfolio.

1. Information We Collect and Process

A. Technical, Device, and Telemetry Data

When you access or play our games, third-party analytics and advertising networks may automatically receive technical device telemetry necessary for operating the application:

• Pseudonymous Identifiers: Android Advertising ID (AAID/GAID), IP address, and platform-generated installation identifiers.
• Device and Operating System Specifications: Hardware model, manufacturer, OS version, system language settings, screen density/resolution, and available RAM.
• Stability & Crash Telemetry: Anonymized stack traces, crash dumps, render engine diagnostics, and network latency status used strictly to resolve bugs and optimize framerates.

B. Game State and Local Preferences

• Local Device Storage (PlayerPrefs / SharedPreferences): Audio volume (music & sound effects), table cloth themes, tile face styles, game mode preferences, and offline high scores are stored locally on your device hardware.
• Transient Multiplayer State (Hong Kong Mahjong Game & Mahjong 3D): When playing online multiplayer matches, temporary in-game action packets (such as selected avatar index, temporary nickname, and tile discard/meld actions) are transmitted securely over WebSocket to coordinate realtime board synchronization among table participants. These session packets are ephemeral and discarded once the match concludes.
• Offline Zen Progress (ASMR Mahjong): Board layout configurations, undo/hint states, and puzzle completion stats reside completely on your local device.

2. Third-Party Services & Monetization

To support ongoing server infrastructure, multiplayer synchronization, and continuous updates while keeping our games free to enjoy, we partner with trusted industry-standard SDK providers:

• Google Mobile Ads (AdMob):
  We display advertisements provided by Google AdMob, which may include banner ads, interstitial transition screens, and opt-in rewarded video ads. Google AdMob may collect and process device identifiers, ad interaction data, and network connection info in accordance with Google's Privacy Policies.
  • Google Privacy Policy
  • How Google Uses Information From Sites or Apps That Use Our Services
• Google Play Services:
  Provides essential Android OS bridging, application integrity checks, and distribution updates on Android devices.
  • Google Play Services Privacy Policy
• Firebase (Crashlytics & Core Diagnostics):
  Monitors application stability, fatal exceptions, and performance benchmarks to help our development team quickly pinpoint and resolve technical defects.
  • Firebase Privacy and Security

3. How We Use Collected Information

Information processed by our games is utilized strictly for legitimate operational purposes:

• To provide, operate, and maintain smooth single-player and multiplayer tabletop gameplay.
• To detect, diagnose, and resolve technical bugs, memory anomalies, and connection drops.
• To serve non-intrusive advertisements that support free gameplay without paywalls.
• To protect players against malicious activities, packet manipulation, and unfair gameplay.
• To maintain full compliance with Google Play Developer Program Policies.

4. Advertising ID & User Opt-Out Choices

You have full control over the advertising identifiers utilized by third-party advertising networks on your Android device:

• Reset or Delete Android Advertising ID:
  On your Android device, open Settings > Google > Ads (or Privacy > Ads). From there, you can tap "Reset advertising ID" or choose "Delete advertising ID" to restrict personalized ad tracking across all apps.
• Non-Personalized Ads:
  When personalized ads are turned off or unavailable, Google AdMob serves contextual or non-personalized advertisements that do not target your behavioral profile.

5. Data Retention & Deletion Policy

We retain gameplay and telemetry data only as long as necessary to fulfill the operational purposes described in this policy:

• Local Data Removal: Because game history, theme selections, and preferences are saved locally on your mobile device, you can permanently erase all local game data at any time by navigating to Android Settings > Apps > [Game Name] (Hong Kong Mahjong Game / ASMR Mahjong / Mahjong 3D) > Storage > Clear Data / Clear Cache, or by uninstalling the application.
• Multiplayer Transient Data: Multiplayer room states and discard events are held in volatile server memory only for the duration of the match and are discarded after the room closes.
• Data Deletion Requests: If you have questions regarding any server logs or wish to request data deletion associated with your advertising identifier, please email our support team at illumina.dev.soft@gmail.com.

6. Children's Privacy (COPPA & Families Compliance)

We place utmost importance on protecting the privacy of young players. Our games (Hong Kong Mahjong Game, ASMR Mahjong, and Mahjong 3D) are not directed to children under the age of 13. We do not knowingly collect, request, or solicit personal information from children under 13 years of age. If we learn that we have unintentionally collected personal information from a child under 13 without verifiable parental consent, we will promptly delete that information from our records.

7. Security Measures

We implement reasonable administrative, technical, and physical safeguards to protect information against unauthorized access, loss, or alteration. Multiplayer communications between your device and our backend servers are routed through secure, encrypted communication protocols (TLS/WSS).

8. International Privacy Rights (GDPR & CCPA)

Depending on your geographic jurisdiction, you may have specific privacy rights:

• European Union / UK (GDPR): You have the right to request access to, rectification of, or erasure of any personal data we hold; the right to object to or restrict processing; and the right to lodge a complaint with your local Data Protection Authority.
• California Residents (CCPA/CPRA): You have the right to know what categories of personal information are collected, request deletion, and opt out of the "sale" or "sharing" of personal data for cross-context behavioral advertising. We do not sell your personal data.

9. Changes to This Privacy Policy

We may update our Unified Privacy Policy periodically to reflect changes in our gameplay features, third-party technologies, or legal requirements. Any modifications will be posted directly to this URL with an updated "Effective Date". We encourage you to review this page periodically to stay informed.
