Legal & Data Transparency
Privacy Policy
🔒 100% On-Device Processing
Mahjong Blast processes your active media, text, or geometric calculations locally on your physical hardware.
🚫 Zero Account Tracking
No account registration, login credentials, email scraping, or user profiling is required to use the Application.
🛡️ Safe Third-Party Practices
Diagnostics, app stability, and optional advertising are handled via industry-standard Google Play Services and AdMob.
1. Overview & Introduction
This Privacy Policy applies to the mobile software application Mahjong Blast: 3D Tile Match (the "Application"), developed and published by Corvas ("we," "our," or "Service Provider").
We are dedicated to building privacy-respecting, high-performance creator tools and utilities. We believe that your creative work, device files, and private inputs belong strictly to you. This document provides a declarative, transparent disclosure of how the Application handles device hardware, permissions, and diagnostic data.
2. Architecture & Data Handling Architecture
To avoid ambiguity, we explicitly delineate data handling across four distinct operational boundaries:
A. Personal Information Collected Directly by Developer
None. No personal profiles, passwords, or contact lists are collected.
B. Data Processed Locally On Your Device (Never Uploaded)
Player progression, cleared level milestones, high scores, daily login streaks, unlocked tile sets, and audio settings are saved locally on your device via Android shared preferences.
C. Data Transmitted to Our Backend
None. All board configurations, physics, and tile matching logic execute on-device.
D. Diagnostic & Advertising Data Collected Automatically by Third Parties
When you download and use the Application, standard operating telemetry may be generated by certified third-party SDKs (such as Google Play Services, Firebase Crashlytics, and Google AdMob). This may include anonymous device identifiers, Android OS build, hardware architecture, screen resolution, and crash stack traces.
Device Permissions & Data Access
To provide its core features, Mahjong Blast may request the following device permissions:
Purpose: Required to fetch daily challenge puzzles, verify in-app purchases, and load optional rewarded video ads.
Data Handling: Transmits only anonymous game state verification tokens and ad requests.
Third-Party Service Providers & SDKs
The Application relies on trusted third-party service providers solely for core functionality, advertising (where applicable), and app stability monitoring. These providers collect diagnostic or advertising device tokens according to their respective privacy policies:
| Service | Function / Purpose | Privacy Policy |
|---|---|---|
| Google Play Games / Services | Facilitates optional cloud save backup, leaderboards, and achievements. | View Policy ↗ |
| Google AdMob | Displays banner, interstitial, and voluntary rewarded video ads (for free power-up hints). | View Policy ↗ |
| Google Play In-App Billing | Handles digital purchases of coin packs, power-ups, and permanent ad-free upgrades. | View Policy ↗ |
3. Advertising & Commercialization
Mahjong Blast is supported by non-intrusive advertising (Google AdMob) in its free tier to support ongoing development and maintenance. Ad networks may collect anonymous advertising identifiers (Google Advertising ID) to deliver relevant or non-personalized advertisements based on user settings.
Product-Specific Disclosures & Clarifications
Virtual Goods & Entertainment
Mahjong Blast is a skill-based puzzle game intended for entertainment purposes only. In-game power-ups, coins, and streak badges possess no cash value and do not constitute gambling or wagering.
4. Data Retention, Local Storage & Deletion
Because the Application does not maintain user accounts on remote servers, your files, documents, settings, and outputs reside exclusively on your physical mobile device. You have absolute control over this data at all times:
- Local Deletion: You can delete exported files or documents at any time using your device's file manager or gallery.
- App Cache & Storage Reset: Navigating to Android Settings > Apps > Mahjong Blast > Storage > Clear Storage immediately purges all local cached data.
- Uninstall: Uninstalling the Application permanently removes all sandboxed preferences and internal application files.
5. Children's Privacy
The Application does not knowingly solicit or collect personally identifiable information from children under the age of 13 (or under 16 in applicable jurisdictions). If you are a parent or guardian and believe your child has provided personal information to third-party SDKs through the app, please contact us and we will assist in taking appropriate corrective steps.
6. User Rights (GDPR / CCPA / International Regulations)
Depending on your jurisdiction, you may hold specific legal rights regarding personal data, including rights of access, rectification, objection to processing, and erasure. Because we do not associate your use of the app with your identity, we cannot query or provide records tied to you. However, you can manage diagnostic and ad personalization preferences directly through your Android device settings (Google > Ads > Delete advertising ID).
7. Contact Information & Policy Updates
We may periodically update this Privacy Policy to reflect app updates, new platform guidelines, or legal obligations. Significant revisions will be reflected with a revised "Effective Date" at the top of this document.
