LAKASA, LLC ("we," "us," or "our") developed Prism Stack as a free mobile application. This Privacy Policy explains how we handle information when you use our app.

Information We Collect

We do not directly collect any personal information. Prism Stack does not require account creation, registration, or sign-in to play the game. However, third-party services integrated into the app may collect certain data as described below.

Data Stored on Your Device

Prism Stack stores the following data locally on your device only:

• Your high scores and game statistics
• Achievement progress
• Game preferences (theme, difficulty, sound settings)
• Daily challenge streak data

This data is stored using Android DataStore and never leaves your device. It is not transmitted to us or any third party. If you uninstall the app, this data is automatically deleted.

Google Play Games Services

Prism Stack offers optional integration with Google Play Games Services for leaderboards. If you choose to use this feature, your scores may be shared with Google in accordance with Google's Privacy Policy. Use of Google Play Games Services is entirely optional and the game functions fully without it.

Advertising

Prism Stack displays advertisements through Google AdMob. AdMob may collect and use certain data to serve and personalize ads, including:

• Advertising ID (a resettable device identifier)
• Device information (device model, operating system version)
• Ad interaction data (impressions, clicks)
• General location data (IP-based, not precise GPS)

This data is collected and processed by Google in accordance with Google's Privacy Policy. You can opt out of personalized advertising by adjusting your device settings under Settings > Google > Ads > "Opt out of Ads Personalization," or by resetting your Advertising ID.

We do not have access to any personally identifiable information collected by AdMob. Ad revenue helps keep Prism Stack free for all players.

Third-Party Services

Prism Stack integrates the following third-party services:

• Google AdMob — Used to display advertisements. See the Advertising section above for details.
• Google Play Games Services — Used for optional leaderboard functionality.

We do not integrate any additional third-party analytics or tracking services. We do not use cookies, web beacons, or similar technologies.

Children's Privacy

Prism Stack is not directed at children under the age of 13. While we do not directly collect personal information, third-party advertising services (Google AdMob) may collect device identifiers as described above. If you are a parent or guardian and believe your child has been exposed to inappropriate data collection, please contact us and we will take steps to address the concern.

Permissions

Prism Stack requests the following device permissions:

• Vibrate: Used to provide haptic feedback during gameplay (piece placement, line clears, combos). No data is collected through this permission.
• Internet: Used to serve advertisements via Google AdMob and to connect to Google Play Games Services for leaderboards.
• AD_ID: Used by Google AdMob to serve and measure advertisements.

Data Sharing

We do not sell, trade, or transfer any user data to third parties. Google AdMob and Google Play Games Services may collect and process data as described in their respective privacy policies. We do not have direct access to any personally identifiable data collected by these services.

Data Security

All game data is stored locally on your device using Android's built-in secure storage mechanisms. Data transmitted to third-party services (AdMob, Play Games) is handled according to Google's security standards.
