Stack & Drive (“the game”) is a casual mobile game for iPhone, iPad and Android. This policy explains what information is collected when you play, why it is collected, and the choices you have. The game does not ask you to create an account, and we do not collect your name, email address, phone number or precise location.
1. Information stored on your device
Your game progress, including level, coins, upgrades, skins, settings, daily streak and missions, is saved only on your device. We do not upload it to our own servers. Uninstalling the game deletes this data.
2. Advertising (Google AdMob)
The game shows optional rewarded video ads and occasional full-screen ads, provided by Google AdMob. To serve and measure ads, and to prevent fraud, Google may collect:
- device identifiers, such as the Android advertising ID or the iOS IDFA (only if you allow tracking);
- your IP address and an approximate location derived from it;
- device model, operating system version, and how you interact with ads;
- diagnostic and performance data about ad delivery.
Your choices
- EEA, UK and Switzerland: we ask for your consent before personalised ads are shown, using Google’s consent tool.
- iOS: we ask your permission through Apple’s App Tracking Transparency prompt before any tracking. If you decline, ads are not personalised using your IDFA.
- In the game: you can change your ad choices at any time in Settings → Ad Privacy Choices.
- On your device: you can reset or delete your advertising ID in your device settings. On Android, go to Settings → Privacy → Ads. On iOS, go to Settings → Privacy & Security → Tracking.
Google’s use of this data is described at How Google uses information from sites or apps that use its services.
3. In-app purchases
Coin packs and “Remove Ads” are sold through the Apple App Store or Google Play. Apple or Google handles the payment entirely, and we never receive your payment details. We only receive confirmation of the purchase so the item can be delivered. “Restore Purchases” in Settings asks the store to re-deliver items you have already bought.
4. Notifications
If you allow notifications, the game schedules reminders locally on your device, for example when your daily reward or free spin is ready. No data is sent to a server for this, and you can turn notifications off at any time in your device settings.

6. Children
The game is intended for players aged 13 and over. It is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided personal information, contact us and we will help remove it.
7. Data retention and deletion
We keep no account or server-side game data, so uninstalling the game removes all of your game data. For advertising data held by Google, use Google’s privacy controls or reset your advertising ID. You can also email us with any data request and we will respond.
8. Security
All data sent by the game, such as ad requests and purchase confirmations, is encrypted in transit using HTTPS.
9. Changes to this policy
We may update this policy as the game changes. The effective date at the top shows the latest version. Significant changes will also be noted in the game’s update notes.
