Information We Collect and How It Is Used ### A. Local Device Storage (Non-Personal Gameplay Data) Stackly stores essential gameplay progress and user preferences locally on your physical device storage (via secure LocalStorage): - High scores, active score tallies, and combo multipliers. - Visual custom preferences (e.g., Cyber Neon / Pastel themes, zoom factor, bloom glow, slice physics). - Sound effects and music mute toggles. - Premium ad-free status flags. *Note: This gameplay data remains strictly on your local device and is never uploaded, transferred, or sold to external servers.* ### B. Device Telemetry & Fleet Administration (Supabase) To ensure server uptime, distribute emergency maintenance notices, and safeguard application integrity, Stackly performs an automated, encrypted handshake with our secure cloud infrastructure (**Supabase**): - **Pseudonymous Anonymous Tag:** A generic, non-personal player label (e.g., `Stacker #6611`) generated randomly on initial launch. - **Hardware Profile:** Device manufacturer, hardware model, operating system version, and installed build version (`1.0.0`). - **Session Telemetry:** Total lifetime session count and timestamp of recent activity to ensure minimum required version compliance. - **Device Identifier:** A randomly generated alphanumeric hardware UUID (`dev_...`) used exclusively for administration, such as enforcing maintenance lockouts or account suspensions. ### C. Advertising Networks (Google AdMob) Stackly is supported by advertising delivered through the **Google Mobile Ads SDK (AdMob)** to allow free access to the game for all players: - **App Open Ads:** Full-screen advertisements displayed upon application cold launch or resuming from the background. - **Banner Ads:** Persistent banner advertisements anchored to the bottom of the display. - **Rewarded Video Ads:** Optional, user-initiated video advertisements that reward players with in-game tower revives. Google AdMob may collect and process your device's Google Advertising ID (AAID / GAID), coarse location derived from IP address, and ad interaction metrics (impressions, clicks, completed views). For more information on how Google processes ad data, please review [Google's Privacy & Terms](https://policies.google.com/technologies/ads). --- ## 4.
