Unstack Privacy Policy

Unstack is a free game for iPhone and Android made by Xronocore ("we", "us"). This page explains what information the game uses and who it is shared with. In short: we don't ask you to create an account, and we don't collect personal information ourselves. The ads in the game are provided by Google, and Google handles some information to show them.

Information stored on your phone

Your progress (your current level, coins, items and daily reward streak) is saved only on your iPhone or Android phone. We don't receive it and we can't see it. If you delete the game, this information is deleted with it.

Ads

Unstack shows ads from Google AdMob: short videos you can choose to watch to earn items or bonus coins, and banner ads on some screens. To show and measure ads, and to prevent fraud, Google and its partners may collect and use information from your device, such as:

• your device's advertising identifier (on iPhone only if you allow tracking, see below; on Android the Google advertising ID, which you can reset or delete)
• your IP address and the approximate location it implies
• device and app information, such as the device model, iOS or Android version and app version
• how you interact with ads, such as whether an ad was shown, viewed or tapped

We don't receive this information. You can read how Google uses it in How Google uses information from sites or apps that use our services and in the Google Privacy Policy.

Your choices about tracking

• Allow tracking (iPhone). The first time you open the game, your iPhone asks whether Unstack may track your activity across other companies' apps and websites. If you allow it, ads can be matched to your interests. If you decline, you still see ads, but they are less personalised. You can change your choice at any time in Settings > Privacy & Security > Tracking.
• Europe, the UK and Switzerland. If you are in one of these regions, the game first shows a consent message from Google asking how your information may be used for ads. You can change your answer later with the Privacy settings button on the game's home screen.
• Reset your advertising identifier. On iPhone, you can reset it, or limit ad tracking, in your iPhone's settings. On Android, open Settings > Privacy > Ads (the path can differ by phone) to reset your advertising ID, delete it, or turn off ad personalisation.

Purchases

If the game offers purchases (for example, removing banner ads), they are handled entirely by Apple (on iPhone) or Google Play (on Android). We never see your payment details.

Children

Unstack is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has given us personal information, please contact us and we will delete it.

Your rights

Because we don't collect or hold your personal information, there is nothing for us to look up or delete. For information handled by Google for ads, you can use the privacy controls Google provides, including your Google account's My Ad Center. Depending on where you live, you may also have rights to access, correct or delete your information, or to object to how it is used.

Changes to this policy

If we change how the game handles information, we will update this page and its effective date.
