The app uses Google Firebase Analytics to record events generated by the game. Examples include:
Firebase may also automatically process technical information such as your device model, operating system, app version, language, app-instance and installation identifiers, IP address, and an approximate location derived from your IP address. Purchase events may include the product identifier, price, and currency. In the iOS app, Analytics advertising storage, advertising user-data sharing, and ad personalization are disabled by default; gameplay measurement continues separately from optional advertising.
The app uses the Google Mobile Ads SDK (AdMob) for rewarded ads and interstitial ads between stages. When the SDK initializes or an ad is requested, displayed, or watched, Google may automatically collect or process:
This data is used to deliver and measure ads, provide analytics, prevent fraud and abuse, and maintain service security. Data sent to Google is encrypted in transit. The app does not request precise or GPS location.
The Supporter Pack is processed by Google Play Billing on Android or Apple StoreKit on iOS. The app receives product, transaction, purchase-status, and entitlement information to provide benefits and restore purchases. Purchase events can also be measured by Firebase Analytics. We do not receive your payment-card number or bank details. The platform store processes payment and retains transaction records under its own privacy policy.
On Android, the game uses Google Play Games Services; on iOS, it uses Apple Game Center. These features are optional for core gameplay. The platform may sign you in automatically according to your account settings.
When signed in, the app receives your platform gamer ID, display name, and avatar when available. It reports achievement progress and leaderboard scores, including run details such as stage, node, and gold earned. Your gamer profile, scores, and achievements may be visible to other players according to the platform's profile and privacy settings.
The game can back up and restore your save through Google Saved Games on Android or Apple iCloud on iOS. This includes progress, unlocks, crystals, run records, and game settings. These backups are associated with your Google Play Games account on Android or iCloud account on iOS. Apple cloud saves require iCloud and iCloud Drive. Google and Apple use separate save services; they do not provide an Android-to-iOS save transfer through this game.
We use gameplay and technical information to understand how the game performs, find bugs, improve balance, and decide which features need attention. Ad-related information is used to request, display and measure ads, deliver optional ad rewards, and detect invalid or fraudulent activity. Platform gamer information connects your progress to your platform account, displays your profile and rankings, and supports achievements and save backup or restoration.
Rewarded ads are optional. The game identifies the reward before you choose to watch, and an ad starts only after you select the relevant watch-ad button. Declining an ad does not remove the normal rewards earned through gameplay. Ad availability depends on your connection, region, device settings, and Google's ability to provide an eligible ad.
For players without the Supporter Pack, an interstitial ad may appear after a boss battle, before the next stage map. It does not grant a reward. Closing the ad returns you to the game. The Supporter Pack removes both rewarded and interstitial in-game ads; its benefits do not require watching an ad.
Where required, Google displays a privacy message before the app requests ads. If Google requires an ongoing privacy-options entry point in your region, you can reopen that form from Settings → Privacy & Ads.
On iOS, the app asks for App Tracking Transparency permission before allowing advertising-identifier access. Allowing tracking lets Google AdMob personalize and measure ads across apps and websites. Declining tracking does not block gameplay; eligible ads can still be served without IDFA, subject to your consent choices and availability.
On Android, AdMob may request ads from Meta Audience Network through mediation. Meta may process device and advertising identifiers, IP-derived approximate location, ad interactions, and diagnostics to deliver and measure ads and prevent fraud, subject to applicable consent and device settings. This advertising integration is separate from the optional Meta app measurement below and is not included in the iOS app. See the Meta Privacy Policy.
Version 0.6.0 adds optional Meta App Events to measure which Facebook and Instagram ads lead to installs and app activity. It starts only after you choose Allow and confirm that you are at least 18. Declining does not affect gameplay, rewards, or your scores. This choice is separate from Google's advertising choices.
If enabled, Meta may receive install and session events, device and operating-system information, an app-instance identifier, IP address, advertising identifier (where available), and install-referrer attribution. Meta uses this information for ad measurement and optimization under its Privacy Policy. We do not provide Meta with your platform gamer ID, save files, inventory, or detailed scoring ledger.
You can change this choice in Settings → Privacy & Ads. Withdrawing stops further automatic event delivery; requests already in transit cannot be recalled. You can also manage your advertising identifier in Android settings and your activity information in Meta's privacy controls. Meta measurement is not included on iOS and is disabled in development and test builds.
We use Google Firebase Analytics for gameplay and purchase analytics, Google AdMob and the Google Mobile Ads SDK for rewarded and interstitial ads, and Meta Audience Network for mediated ads on Android. Advertising providers process information for ad delivery, measurement, and fraud prevention.
Google may process data as described in the Google Privacy Policy and Google's information about how it uses data from sites or apps that use its services. We do not sell or rent your personal data.
We also use Google Play Games Services and Saved Games for Android gamer profiles, achievements, leaderboards, and save backups, and Apple Game Center and iCloud for corresponding iOS game services and saves. Apple processes game-service and iCloud data under its Privacy Policy and Game Center privacy information.
