Privacy Policy — English
Last updated: July 1, 2026
This Privacy Policy explains how Nexus collects, uses, and protects information when you use the app.
This game uses third-party services including Firebase services and Google AdMob. These services may collect and process data according to their own privacy policies.
1. Information we may collect
The app may collect or process the following types of data:
- Game usage data such as screens visited, level progress, puzzle attempts, rewards, and interactions.
- Device technical information such as model, operating system, language, region, and device identifiers.
- Ad data such as rewarded ad availability, impressions, clicks, rewards earned, and measurement signals.
- Local progress data such as lives, coins, hints, completed levels, settings, and reward history.
- Service request data needed to operate backend features, prevent abuse, and keep gameplay systems reliable.
2. Firebase services
We use Firebase services to initialize app services and support backend features such as progress-related operations, life systems, and server-side checks when those features are configured.
Firebase may process technical identifiers, request metadata, diagnostics, and service interaction data required to provide, secure, and improve those services.
3. Google AdMob
We use Google AdMob to display ads in the app, including rewarded ads that may grant gameplay benefits such as reviving a life or duplicating a reward.
AdMob may use advertising identifiers, device data, approximate location, ad interactions, and other signals to serve, limit, measure, and improve ads. Depending on your region and device settings, ads may be personalized or non-personalized.
4. In-game rewards and purchases
Nexus may include in-game resources such as coins, hints, lives, rewards, and level progression. Some actions may spend or grant in-game currency, and some rewards may be connected to rewarded ads.
The current app does not require us to receive or store full credit card data. If real-money purchases are added in the future, transactions will be handled by the applicable app store or payment provider.
5. How we use information
- To operate and improve the game.
- To save progress, settings, rewards, lives, coins, and hints.
- To show ads and reward ad-based interactions.
- To support backend features and validate gameplay-related operations.
- To analyze performance, retention, errors, and game balance.
- To prevent abuse, fraud, or reward manipulation.
6. Data sharing
We may share data with service providers required for app functionality, including Google Firebase and Google AdMob. We do not sell your personal data directly.
7. Children
The app is not intentionally directed at children under 13 years old. If you believe a child has provided personal data improperly, contact us so we can review and remove the information when appropriate.
8. Security
We use reasonable measures to protect app data. However, no electronic transmission or storage method is 100% secure.
9. Your rights and choices
You may limit ad tracking in your device settings, reset the advertising ID, and manage app permissions. You may also request information or deletion of data by contacting us.
