Privacy Policy

This is the privacy policy for Bluraysoftware ("we", "us", or "our"), the operator of the KX Works brand. This policy describes how information is handled on kxworks.dev, in its browser game demos, and in our mobile applications, including Street Corner Mahjong (街角麻雀), Melody 2048 and Mewo 2048. Contact us at admin@bluraysoftware.com.

Data practices differ between products and versions. The mobile services described for Melody 2048 do not automatically apply to Street Corner Mahjong, browser demos or Mewo 2048. Websites and tools linked from our portfolio have their own privacy policies.

1. Website and Browser Games

We use Google Analytics 4 to understand website traffic and usage. It uses cookies and processes information such as pages visited, referring websites, browser and device information, and interactions. This information is sent to Google for analytics. We do not send game saves or payment details through this website analytics code. You can block analytics cookies through your browser settings or use the Google Analytics opt-out browser add-on. Learn more about how Google processes information from sites that use its services.

You can browse this website and play its demos without creating an account. Some games store scores, progress, preferences or tutorial state in your browser's local storage. This storage is used to remember your game experience; clearing site data in your browser removes it and may reset your progress.

The website does not embed the mobile advertising, purchase or Firebase services described below. Our hosting and content-delivery providers receive technical request information, such as your IP address, requested URL, browser information and access time, to deliver pages and resources and maintain service security. These requests are separate from the game data stored in your browser.

2. Mobile Game Data

Our games do not require a separate KX Works account. Game saves and preferences are stored on your device. Device or operating-system backups may retain or restore local data under your own backup settings. Local saves are separate from the service data described below.

Mewo 2048: the initial mobile release stores game progress and settings locally and does not include advertising, analytics, crash-reporting, account-login or cloud-save services. Its product-specific policy is available at Mewo 2048 Privacy Policy.

Street Corner Mahjong (街角麻雀): all currently implemented versions store the current match and its backup, settings, tutorial state, play activity and game statistics in local storage. They do not include account-login, cloud-save, purchase, Firebase Analytics or Crashlytics services. The browser demo and Android builds made with advertising disabled do not load the mobile advertising services described below. The advertising-enabled Android version prepared for Google Play includes Google AdMob and Google's User Messaging Platform as described in Section 3. Android or device backup features may copy and later restore local game data according to your device, account and backup settings.

When you choose the Privacy Policy or Terms of Service link in Street Corner Mahjong, the app asks the operating system to open the corresponding kxworks.dev page in your browser. The website hosting and content-delivery providers then receive ordinary request information such as your IP address, requested URL, browser or device information and access time. The app does not add your game saves, settings or statistics to these links.

Melody 2048: mobile versions with the services below enabled process advertising, usage, diagnostic and purchase information in addition to local game saves. The available services depend on your app version, platform and configuration.

3. Mobile Advertising

The advertising-enabled Android version of Street Corner Mahjong uses the Google Mobile Ads Next-Gen SDK to provide ads. Depending on the version and configuration, these may include interstitial ads between game sessions or a native ad when returning to the game. Developer test builds use Google's official test ad units and are not intended for public distribution, but they can still contact Google's advertising and consent services. Melody 2048 mobile versions use Google AdMob to provide ads, including rewarded ads.

Google's advertising SDK automatically processes and shares the device's IP address, which can be used to estimate approximate location; app and ad interactions such as app launches, taps and video views; diagnostic information about the app and SDK; and device or account identifiers such as the Android advertising ID and app set ID. Google states that it uses these data for advertising, analytics, and fraud prevention, security and compliance. These data are separate from Street Corner Mahjong's local game saves, settings and statistics, which the app does not add to ad requests.

Street Corner Mahjong uses Google's User Messaging Platform to request current consent information when the advertising-enabled Android app starts. Where required for the user's region or message configuration, it displays a consent message before requesting ads and provides an in-app advertising privacy entry point when Google reports that one is required. Ad personalization and the ads that can be requested depend on the user's choices, device settings, region and available controls.

Where available, users can review or change their choices through the app's advertising privacy entry point and can reset or delete the Android advertising ID through device settings. Choosing non-personalized or limited ads, or changing the advertising ID, does not necessarily stop ads or all technical, measurement, analytics, diagnostic or fraud-prevention processing. Removing the app does not automatically erase information already processed by an advertising provider.

See the Google Privacy Policy, how Google uses information from apps that use its services, and the GMA Next-Gen SDK data disclosure.

4. Melody 2048 Analytics and Crash Reports

Melody 2048 uses Google Analytics for Firebase to understand app usage and improve the game, and Firebase Crashlytics to diagnose failures. When these services are enabled, they process app or installation identifiers, device and app-version information, usage events, and crash or error details. Usage events can include gameplay, feature use and advertising interactions; diagnostic reports can include error messages and stack traces. Street Corner Mahjong does not integrate these separate Firebase Analytics or Crashlytics services, but the advertising SDK's own interaction, analytics and diagnostic processing described in Section 3 still applies to its advertising-enabled Android version.

These services transmit information to Google; local game saves do not mean that all app data stays on your device. Ad privacy controls apply to advertising and are not a general switch for analytics or crash reporting. See Firebase privacy and security information and the Google Privacy Policy.

5. Melody 2048 Purchases

In mobile versions offering in-app purchases, the app store processes the payment. RevenueCat manages purchase validation, product access and restoration of eligible purchases. It processes an app user identifier, purchase or transaction records, product identifiers and entitlement status, together with technical information needed to provide the service. You do not need to create a KX Works account for this identifier to exist.

We do not receive your full payment-card details from the app store. Purchase records are separate from local game progress and can remain with the store and purchase service after an app is removed. See RevenueCat's Privacy Policy and the privacy information of the store used for your purchase.

6. Support and Service Providers

If you email us, we receive your email address, message and any attachments you choose to send. We use this information to respond, troubleshoot and handle your request. Please avoid sending passwords, payment-card details or other unnecessary sensitive information.

The hosting, advertising, analytics, diagnostic, purchase and email providers described in this policy process information to perform their respective services. Information may be processed in countries outside your own, according to the applicable service terms and privacy protections. We may also disclose information where required by law or necessary to address security or legal claims.

7. Retention and Security

Browser and device saves remain until removed, replaced or cleared by you, the app, the browser or the operating system. Backups may have separate retention settings. Support correspondence is retained as needed to resolve requests and meet applicable obligations. Advertising, analytics, diagnostic and purchase records are retained according to the service's purpose, applicable settings, provider policies and legal requirements; uninstalling an app does not automatically erase these records.

We use HTTPS for this website. The service providers described above publish their own security practices. No method of transmission or storage can be guaranteed completely secure.

8. Your Choices and Data Deletion

• Browser data: clear stored site data for kxworks.dev in your browser. This may remove scores, preferences and saved progress across its demos.
• Mobile game data: clear the app's storage where supported or remove the app, and review device/cloud backups separately if you want to remove backed-up copies.
• Advertising: use the app's available ad privacy controls and your device's advertising-ID settings. These actions do not erase all previously processed data.
• Requests to us: email admin@bluraysoftware.com with the subject "Data Deletion Request" and the affected product. We may need information to identify the relevant records, and will handle requests within applicable legal deadlines. We cannot identify every installation from an email address alone.
• Provider records: we will handle requests concerning data processed on our behalf and, where appropriate, help direct you to the relevant provider or app store for records they control. Purchase and other records may need to be retained for legal obligations.

There is no separate KX Works account profile to delete. Depending on your location, you may have rights to access, correct or delete personal data, restrict or object to processing, withdraw consent where applicable, or complain to your local data protection authority. Contact us to make a request.

9. Children's Privacy

Our products are not primarily directed to children. We do not knowingly request personal information from children. If you believe a child has provided personal information to us, contact us so we can investigate and take appropriate action. Parents and guardians should review the individual app's store listing and available privacy controls.

10. Changes and Contact

We may update this policy when our products or data practices change. Updates are posted here with a revised date, and additional notice or consent will be provided where required.
