Privacy & Confidentiality

Cube-16 is a unique and innovative concept for representing the 4x4 cube, created as a 2D cross. This concept was invented by Mr. Claude Gonneville, and his work is protected by copyright. The mobile application was developed in partnership with Groupe informatique Momentum inc. (Quebec, Canada).

This policy explains what data is collected, how it is used, and what rights users have.

2.1 Technical and Diagnostic Data

Cube-16 may process limited technical data to keep the app stable:

• Device model, system version, language, and general region
• App version and technical context at the time of an incident
• Internal state useful for diagnosing a crash or error

Cube-16 does not include advertising and does not collect the Android or Apple advertising identifier for personalized advertising. On Android and iOS, Cube-16 uses Firebase Analytics to obtain general statistics about application use and improvement.

2.2 Crash Data

If the app crashes:

• Error trace
• Application state
• Technical device information

On Android and iOS, crash reports and technical diagnostics may be collected via Firebase Crashlytics. On Windows, crash and error diagnostics may be transmitted to and stored on Sentry servers if enabled.

2.3 Usage Data and Analytics

On Android and iOS, Cube-16 uses Firebase Analytics, a service provided by Google, to understand in general how the application is used and to improve the game.

Firebase Analytics may automatically collect:

• App opens, sessions, screen views, and general engagement measurements
• The platform, application version, and general technical information about the device
• The language configured on the device and an approximate country or region that Firebase may infer from a masked IP address. Cube-16 does not access the device's GPS location.
• An identifier specific to the application instance, which Cube-16 does not associate with a name, email address, or advertising identifier
• Certain automatic technical or transactional events, including events related to the application lifecycle and, depending on the platform, in-app purchases

Cube-16 also sends limited events concerning the configuration and use of the game:

• The continent, country or market, and language selected in the application; the theme; the color-blind accessibility option; whether the timer is enabled; the level; the platform; the application version; and free or Premium access
• Changes made to these settings, in the form of the previous and new values
• The level and sequential index of grids started and completed, the completion time when the timer is enabled, and the number of validations
• Completion of the free content, display of the Premium offer, and its general outcome, such as accepted, declined, pending, failed, or restored

Cube-16 does not send Firebase Analytics the contents of grids, entered numbers or candidates, technical grid file names, custom photos or backgrounds, purchase receipts or tokens, or a GPS location.

This data is used to analyze usage, stability, and improvements to Cube-16. It is not sold, is not used by Cube-16 for personalized advertising, and is not used to track users across applications or websites owned by other companies.

2.4 Local Files and Preferences

Cube-16 stores some data locally on the device:

• Game progress, settings, theme and preferences
• Local JSONL log files, if generated
• Custom photos or backgrounds selected by the user, when applicable
• These items remain on the device and are not automatically transmitted, except for the technical data and usage events described in section 2.3

• Improve app stability
• Diagnose crashes and technical errors
• Fix issues and maintain compatibility
• Provide online help and official store purchase features
• Produce general statistics about application use in order to improve Cube-16

No sale of data, no commercial sharing, and no advertising profile.

Limited sharing only with technical providers when their services are used:

• Firebase Crashlytics (Android/iOS) for crash reports and diagnostics
• Firebase Analytics (Android/iOS) for general usage statistics, automatic events, and the limited events described in section 2.3
• Sentry (Windows) for crash and error diagnostics, if enabled
• Google Play Billing or the App Store for in-app purchases

• Crash reports and technical diagnostics may be stored on Google Firebase or Sentry secure servers, depending on platform
• Analytics data may be processed and stored by Google Firebase in accordance with the terms and privacy policies applicable to Firebase Analytics
• Local progress, preferences, JSONL logs and custom images remain on the device
• No Android Advertising ID collected and no personally identifying data intentionally collected
• Encrypted communication (HTTPS/TLS)

• Uninstall the app
• Delete local files, progress and preferences by resetting app data or uninstalling the app
• Request information
• Request deletion of device-associated diagnostics where technically possible
