Stack Grove Privacy Policy

Effective date: 2 November 2026 · Developer: NovaBlue

Short version: Stack Grove does not ask you for any personal information and has no accounts, analytics or tracking of its own. Your best score and settings stay on your phone. The game shows ads from Google AdMob, and Google collects some device data to deliver those ads, as explained below.

1. Who we are

Stack Grove (“the app”) is an offline block puzzle game for Android published by NovaBlue (“we”, “us”). If you have any question about this policy, email flutterboy17@gmail.com.

2. Information stored on your device

The app saves your best score, your level progress and stars, and your sound and vibration settings on your device using Android’s local app storage. This information never leaves your device through us, and we cannot see it. Uninstalling the app or clearing its data deletes it. If you use Android’s own device backup, Google may include it in that backup under Google’s terms.

3. Information we collect

We do not collect, receive or store any personal information. The app has no sign-in, no analytics SDK, no crash reporting service of our own and no servers. The gameplay itself works fully offline.

4. Advertising (Google AdMob)

The app is free and shows ads using the Google Mobile Ads SDK (AdMob), provided by Google LLC. When the app is online, the SDK may automatically collect and share with Google information such as:

Data	Why Google uses it
IP address, which can indicate your approximate location	Delivering ads, fraud and abuse prevention, measuring ads
Device and app identifiers, such as the app set ID	Frequency capping, fraud prevention, ad measurement
Ad interactions (for example ad views and taps) and app usage information	Delivering and measuring ads, analytics for advertising
Diagnostics, such as crash and performance information of the ads SDK	Keeping the ads service working and secure
Basic device information (model, operating system version, language)	Showing ads that work on your device

We configure ads to be non-personalised: we ask Google not to use your data to build an advertising profile or to show you interest-based ads. The app does not request the Android Advertising ID permission. Ads are limited to content rated suitable for teens and older.

Data collected by the SDK is encrypted in transit. Google processes it under its own policies:

5. Consent in the EEA, UK and Switzerland

If you are in the European Economic Area, the United Kingdom or Switzerland, the app shows Google’s consent message before any ads are requested, and ads are only loaded according to your choice. You can change your choice at any time in Settings → Ad privacy choices inside the app.

6. Children

Stack Grove is intended for players aged 13 and older and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child under 13 has provided personal information through the app, contact us and we will help remove it.

7. Your choices and rights

Play offline: with no internet connection no ads are requested and no data is sent to Google.
Delete local data by clearing the app’s storage or uninstalling it.
Control ads personalisation for your whole device in Android Settings → Google → Ads, and visit My Ad Center.
Depending on where you live (for example under the GDPR or US state privacy laws), you may have rights to access, correct or delete personal data. Because we do not hold personal data, requests about advertising data are best sent to Google, but you can always contact us and we will help.

8. Permissions

The app uses the Internet permission so that ads can be loaded. Libraries used for advertising may also check whether the device is online. The app does not access your contacts, camera, microphone, photos, files or precise location.

9. Security and retention

We do not keep any of your data, so there is nothing for us to retain or delete. Google’s retention of advertising data is described in Google’s policies above.

10. Changes to this policy

If we change this policy we will update this page and the effective date above. Significant changes will also be noted in the app’s store listing.
