Privacy Policy

for the mobile game StarFlux (package: com.Starflux.guoguo)

Null Derivative Studio operates the mobile application StarFlux ("App"). This page informs you of our policies regarding the collection, use, and disclosure of personal information when you use our App.

We only integrate Google AdMob as a third-party service provider in the App. No other third-party SDKs are used. By using the App, you agree to the collection and use of information in relation to this policy.

Information Collection and Use

To provide and improve the App, limited information may be collected either by us or by Google AdMob for advertising purposes. We do not directly collect personally identifiable information such as your name, address, or phone number.

Advertising (Google AdMob)

The App uses Google AdMob to display advertisements. AdMob may collect and process data (such as advertising identifiers, device information, IP address, approximate location, and usage data) to provide personalized or non-personalized ads and to measure performance. You can learn how Google uses information from sites or apps that use its services here: Google’s Partner Sites policy, and review AdMob’s privacy information here: Google Privacy Policy and AdMob Help Center.

Depending on your region, you may be shown a consent form (e.g., UMP/consent dialog) to choose whether to receive personalized ads. Your choices can be updated via your device or OS ad-preferences settings.

Log Data

In case of an error in the App, we may access basic technical information made available by the operating system (e.g., error messages, OS version, device model) to diagnose issues. We do not integrate any third-party crash reporting SDKs. Where applicable, aggregate crash/ANR statistics may also be available to us via platform services such as Google Play Console; these are provided by the platform and do not involve additional SDKs in the App.

Cookies

The App itself does not set cookies; however, Google AdMob and related Google services may use cookies or similar technologies for ad delivery and measurement. You can manage or opt out of certain ad cookies in your device settings or via Google Ads Settings (where available).

Children’s Privacy

Our App is not directed to children under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact us so that we can take necessary actions.

Security

We value your trust in providing us your information, thus we strive to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.

Links to Other Sites

The App may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.
