HD Studio is the entity responsible for this app and for this policy. The app name, developer name and package name above are the same ones shown on the app's Google Play listing.
What the developer collects
Nothing. The game has no account, no login, no server of its own and no cloud save. HD Studio operates no backend and receives no personal data from the app — only aggregate, anonymous earnings reports from its advertising partner.
What stays on your device
Your score, best score, coins, level progress, power-up inventory and animal album are stored only in the app's local storage on your phone or tablet. That data never leaves the device. Deleting the app deletes all of it, and it does not transfer to a new device.
What Google collects through the app
The app is free and supported by advertising. Ads are served by Google AdMob, and configuration values are delivered by Firebase Remote Config. Through those Google services, Google may collect:
- your device's advertising identifier — the Android Advertising ID (AAID) on Android, or the Identifier for Advertisers (IDFA) on iOS
- ad interaction data — which ads were requested, shown, viewed or tapped
- approximate location, derived from your IP address
- device and diagnostic information, such as device model, OS version, app version, language and crash data
- a Firebase installation identifier, used only to deliver remote configuration values to this installation of the app
This data is collected and processed by Google, not by HD Studio, and is used to serve and measure advertising and to keep the app working. Google's practices are described at policies.google.com/technologies/partner-sites, developers.google.com/admob/android/privacy/data-disclosure, developers.google.com/admob/ios/data-disclosure and firebase.google.com/support/privacy.
Your choices
On Android. You can reset or delete your advertising ID at any time in Settings → Google → All services → Ads. Deleting it stops personalised advertising on your device.
On iOS. On first launch the system asks whether the app may track you across other companies' apps and websites. Choosing "Ask App Not to Track" means your advertising identifier is not used to personalise ads. You can change it any time in Settings → Privacy & Security → Tracking.
In the EU, the UK and Switzerland. A consent form appears before any ad loads and you may decline personalisation.
Declining changes nothing about the game. Every level, animal and power-up works identically — you will simply see less relevant ads.
Data retention and deletion
Because the developer stores nothing, there is nothing for the developer to retain or delete. Everything the game saves lives on your device and is removed when you uninstall the app. To ask Google to delete advertising data associated with your device identifier, reset or delete that identifier using the steps above. If you have any question about your data, email tranduong2068@gmail.com and we will respond.
Sharing
HD Studio does not sell, rent or share personal data, because it holds none. The only third party involved is Google, acting as the advertising and configuration provider described above.
Children
The app is not directed at children under 13 and does not knowingly collect personal information from them. If you believe a child has provided personal information, contact us and we will act on it.
Changes
If this policy changes, the date at the top of this page is updated, and material changes are noted in the app's release notes on Google Play and the App Store.
