This policy explains what information Stack Ball 3D: Smash & Bounce (“the App”, “we”, “us”) collects when you play, and how it’s used. The short version: the App itself doesn’t ask you to create an account, doesn’t collect your name or contact details, and doesn’t run its own servers — your progress lives on your own device. The one outside service involved is Google AdMob, which powers the App’s ads, and it collects data under its own privacy policy, linked below.
Information stored on your device
The App saves the following locally, using Android’s standard app-storage mechanism (SharedPreferences). None of it is transmitted to us — we don’t operate a backend that receives it:
- Your high score and current level
- Which ball skins, accessories (glasses), and other cosmetic items you’ve unlocked, and which are currently equipped
- Sound and haptics on/off preferences
Uninstalling the App permanently deletes this data along with it, since it never leaves your device in the first place.
Advertising (Google AdMob)
The App shows two kinds of ads. Rewarded video ads are optional — you choose to watch one (for example, to unlock a skin or continue a run after losing). Full-screen ads appear now and then at a break in play — after a level is cleared or a run ends, never while the ball is in motion, never in the first minute of a session and never back to back — and can be closed. These ads are served through Google AdMob. Where the law requires it (the EEA, the UK and Switzerland), Google first shows its own consent form, and Settings → Ad Choices in the App brings it back. To do this, AdMob and its partners may collect and process technical data such as your advertising identifier, IP address, device information, and app-usage data, and may use it to select and measure ads, which can include personalized advertising unless you’ve opted out through your device’s ad settings.
We don’t receive or store any of that data ourselves — it’s handled entirely between your device and Google. For details, see:
You can review or reset your advertising identifier, or opt out of personalized ads, in your device’s settings (on Android: Settings → Google → Ads).
Permissions this App requests
| Permission | What it’s for |
|---|---|
| Vibration | Haptic feedback when the ball hits or bounces off the stack. No data is collected or transmitted through this permission. |
| Internet / network state | Required by Google AdMob to request and display ads. |
Children’s privacy
The App is intended for a general audience and is not directed at children under 13. We don’t knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us at the address below and we’ll address it.
Data security
Because gameplay data is stored locally on your device rather than on a server we control, there’s no central database of player data for us to secure or that could be part of a data breach on our end. Data handled by Google AdMob is secured under Google’s own practices, described in the policies linked above.
Your choices
- Sound and haptics can be turned off from the in-app Settings screen.
- Ad personalization can be limited through your device’s ad settings, as described above.
- Uninstalling the App removes all locally stored data.
Changes to this policy
If this policy changes — for example, if a new third-party service is added — we’ll update the effective date above. Continuing to use the App after a change means you accept the updated policy.
