Scope

This policy applies exclusively to the mobile game Drift & Stack and its optional online features (cloud save, leaderboard, in-app purchases, and advertising).

Data we collect

Authentication: If you use online features, we create an anonymous Firebase user ID or, optionally, link a Google account (email address and display name from Google).

Gameplay data: High scores, merge progress, cloud save blobs, and cosmetic unlocks stored in Firebase Firestore when you use cloud features.

Analytics: Firebase Analytics collects app usage events (e.g. session start, game over, ad interactions) and device information (OS version, device model, app version). No personally identifiable content from gameplay is collected.

Crash reports: Firebase Crashlytics collects crash logs and stack traces to fix bugs.

Advertising: Google AdMob may collect advertising identifiers and interaction data to serve banner, rewarded, and interstitial ads. Rewarded ads are shown only when you choose to watch them for an in-game continue.

In-app purchases: Cosmetic skin purchases are processed by Google Play or Apple App Store. We receive confirmation of purchase and product ID; payment details are handled entirely by the store provider.
