This Privacy Policy describes how Paweł Chilczuk ("we", "us", or "our") handles information in connection with the Brain Numbers mobile application (the "App").
Brain Numbers is a puzzle game. The App itself does not directly collect, store, or process personal data, nor does it maintain an external user database. Gameplay states and settings are stored locally on your device's cache.
However, to provide advertisements and stability monitoring, the App utilizes trusted third-party services that may collect device-related information.
We use third-party libraries that may automatically collect certain non-personal or pseudonymized information when you use the App:
Google AdMob (Advertising): Used to display advertisements. AdMob may collect and process data such as your device's Advertising ID, IP address, device identifiers, and information about your interaction with ads to serve tailored or non-personalized advertisements and prevent fraud.
Firebase Crashlytics (Analytics & Crash Reporting): Used to detect, analyze, and fix technical issues and crashes. Firebase Crashlytics collects crash logs, device state information, unique installation identifiers, and performance metrics. This data is purely used for diagnostic purposes to improve app stability.
The information collected by third-party services is used exclusively to:
Serve and manage advertisements within the App.
Monitor app stability, diagnose technical bugs, and improve user experience.
We encourage you to review the privacy policies of our third-party service providers:
Google Play Services / AdMob / Firebase: https://policies.google.com/privacy
Brain Numbers does not knowingly collect personal information from children. If you believe that a child has provided personal information through our third-party services, please contact us so we can take appropriate steps.
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
