Mahjong Match Privacy Policy

Last updated: July 18, 2026
Effective date: July 18, 2026

This Privacy Policy explains how Aimage Club ("we", "us", or "our") handles information when you use Mahjong Match (Bundle ID: club.aimage.majiang, the "Game"). The current version is a single-player game and does not provide user accounts, social features, cloud saves, or a proprietary backend service, but it uses third-party SDKs including Umeng Analytics and Google AdMob for usage analytics and advertising.

1. Information We Process

1.1 Local game data

The Game stores level progress, coins, energy, stars, items, task status, sound and vibration settings, and necessary rewarded-ad status locally on your device. We do not upload this local game data to our servers. Uninstalling the Game or clearing its data will normally delete this information and it may not be recoverable.

1.2 Google AdMob data

The Game uses Google AdMob to provide banner ads and optional rewarded advertisements. Depending on your device settings, location, and applicable law, the Google Mobile Ads SDK may process device and app information, IP address and approximate location, advertising interactions, device or advertising identifiers where permitted, crash logs, performance data, and SDK diagnostics.

Google processes this information under its own privacy policy. We do not ask for your name, telephone number, contacts, precise location, photos, microphone recordings, or camera content through the Game.

1.3 Umeng Analytics data

The Game uses Umeng+ U-App Analytics through the UMCommon SDK to understand launches, active use, feature usage, level experience, advertising functions, and app stability. The SDK may process:

• Device model, operating-system and app version, language, time zone, and network type;
• IP address and an approximate region inferred from it;
• Device identifiers such as IDFV and Umeng identifiers including UMID/ZID, where permitted;
• Usage events such as app launches, sessions, level starts or results, item usage, ad views, and button interactions;
• Crash, error, performance, and SDK diagnostic information.

Game events sent to Umeng primarily contain level numbers, feature or item identifiers, and advertising counts. They do not contain a user account, name, telephone number, or precise location. Umeng processes the information under its own policy and provides us with aggregated analytics.

1.4 Permissions and tracking choices

Core gameplay does not require access to contacts, camera, microphone, photos, or precise location. If a future feature requires a new permission, we will explain its purpose before requesting access. Where applicable, iOS may present an App Tracking Transparency prompt. You may decline without losing access to core gameplay, although ads may become non-personalized or limited and availability may vary.

2. Purposes

• Save and restore local game progress;
• Load and display optional rewarded ads;
• Verify ad completion and grant the applicable in-game reward;
• Measure launches, active use, level completion, feature interactions, and advertising usage;
• Analyze level difficulty and feature performance to improve the Game;
• Maintain stability and diagnose crashes or ad-loading issues;
• Comply with applicable law and platform requirements.

3. Third-Party Services

4. Sharing and International Processing

We do not sell personal information. Umeng, Google, Apple, and the other services described above may process information to provide analytics, advertising, distribution, and related functions. Information may also be disclosed when required by law, to protect users or the public, or as part of a lawful business succession. Google and other providers may process information outside your country or region under their own policies and applicable legal safeguards.

5. Retention

Local game data remains until you uninstall the Game, clear app data, or reset your device. Retention periods for Umeng analytics and Google advertising data are determined by those providers under their policies, service settings, and applicable law. We retain aggregated analytics only for a reasonable period needed for product analysis.

6. Your Choices and Rights

• Delete local game data by uninstalling the Game or clearing app data;
• Manage tracking and privacy permissions in iOS Settings;
• Decline rewarded ads without losing access to core gameplay;
• Stop the creation of new analytics events by stopping use of or uninstalling the Game;
• Contact us to request access, correction, deletion, withdrawal of consent, or to submit a complaint.

7. Children

The Game is a general-audience casual game and is not specifically directed to children. Users below the age at which they may independently consent under local law should use the Game only with a parent or guardian's guidance. We do not knowingly ask children to provide names, telephone numbers, or contact details.

8. Security

We use reasonable technical and organizational measures to protect information. No mobile device or network environment is completely secure, and we cannot guarantee against events outside our reasonable control.

9. Changes

We may update this Policy when features, third-party SDKs, or legal requirements change. Material changes may be announced in the Game, release notes, or on this page. The date above shows the latest revision.
