Marble Plunge is a casual game developed by LNTT. This notice describes the current development version of Marble Plunge and its online services. The game is not yet publicly released through the app stores.

Game data and accounts

The game saves progress, settings and pending round rewards on your device. If you connect through Game Center, Play Games or the available Google sign-in fallback, our server uses the verified platform account identifier to keep an app-specific account. It stores round results, stars, unlocked progress, Diamond balances and economy operation records so these features can work across sessions. Sign-in credentials are handled by the relevant platform. The game holds platform-authenticated server session tokens in memory. A random guest identifier and guest access capability may be saved on the device so guest progress can be restored. Platform SDKs manage their own sign-in credentials.

Rankings can display your platform gamer name and game results to other players. Guest rankings use a generated label. Friends rankings are optional and use platform friend identifiers when you grant the platform's friend-list permission. We do not use an email address as a public ranking name.

Diamonds, purchases and rewarded advertisements

Our server records earned, advertising and purchased Diamonds separately, along with item activations and identifiers needed to prevent duplicate grants. Optional rewarded advertisements share a daily claim limit maintained using server time. A failed or unverified ad does not authorize a reward.

Apple processes iOS purchases through the App Store. We do not receive your payment-card information. Our server verifies Apple transaction information and records the product, transaction identifier, quantity, environment, delivery and refund adjustments. A pending or unverified purchase does not authorize purchased Diamonds.

Google AdMob supplies advertisements. Its SDK may process technical connection and device information, including IP addresses, device identifiers and ad-interaction information, to deliver advertisements, prevent fraud and measure ad performance. Google describes its processing in its privacy policy and advertising information. Test advertisements still make SDK requests and do not mean that no information is processed.

The current development build uses conservative child-directed and under-age advertising request settings. Production advertising remains disabled while audience and store configuration are being finalized. When the advertising SDK requires consent or privacy choices, the game uses Google's consent interface and provides an Ad privacy choices entry in the profile when required. Watching a rewarded advertisement is optional; ordinary round rewards do not depend on watching one.

Service providers and purpose

Our app services use Google Cloud and Firestore for hosting and storage. Apple and Google provide their respective account, purchase and advertising services under their own policies. We use game and economy records to provide progress and rankings, deliver and verify rewards and purchases, handle refunds, prevent repeated or fraudulent claims, and respond to support requests.

Optional usage analytics uses Google Firebase Analytics in a dedicated Marble Plunge project. Collection is off until you choose Allow analytics in the first-launch prompt or in Settings. You can choose Not now and still play. When enabled, Google processes an app-instance identifier, technical app/device information and usage events, including screen views, level starts and results, completion duration and power-up usage. We do not send player names, account identifiers, sign-in credentials or payment receipts in these events. Analytics advertising consent remains denied. You can disable usage analytics in Settings; this stops future collection and resets the local analytics identifier. This does not automatically erase events already received by Google. Account deletion also disables analytics on this device. Platform and advertising providers separately process information needed for their services.

Account deletion and retention

You can request deletion of the app account from the profile screen. This removes the app's progress, ranking and wallet records through our account-deletion process. Limited deletion and transaction replay markers may remain to prevent a deleted account or an already-processed purchase from being recreated or credited again. Deleting the game account does not delete your Apple or Google account and does not itself request a store refund.

After deleting the game account, automatic Game Center connection remains disabled until you choose to sign in again from the profile. Existing platform accounts, platform achievements and store purchase records are controlled by their respective providers.

We retain app information while needed to provide these features and support transaction integrity. For access, correction, deletion or other privacy questions, contact us using the address below. We may need to verify that a request relates to your account.
