SeKToR ("we", "us", or "our") built the Mind Citadel app (the "App") as a free application with optional in-app purchases. This Privacy Policy explains how we collect, use, and protect information when you use our App.
1. Information We Collect
a) Account Information
When you sign in with Google Sign-In, we receive your Google account display name, email address, and profile photo URL. This information is used to create and identify your in-game profile.
b) Game Data
We store your gameplay progress, including in-game resources, building levels, quiz statistics, achievements, inventory, skill tree, and leaderboard rankings. This data is stored on Firebase Firestore servers and is associated with your account.
c) Device and Usage Information
We may automatically collect certain technical information such as device type, operating system version, and app interaction data for the purpose of improving the App and diagnosing issues.
d) Advertising Data
The App uses Google AdMob to display rewarded advertisements. AdMob may collect device identifiers, IP address, and ad interaction data in accordance with Google's Privacy Policy. You can opt out of personalized ads in your device settings.
