Privacy Policy
The short version: ZERO doesn't collect anything about you that it doesn't need, and nothing is sold.
What we collect
ZERO does not require an account with us, and we don't run our own analytics or tracking. We never sell your information, and we never receive your name, email address or contacts.
Advertising (Google AdMob)
The free version shows ads from Google AdMob. To serve ads, measure them and prevent fraud, Google may collect device information such as your IP address (which gives an approximate location), device and app identifiers, how you interact with ads, and basic diagnostic data.
iOS asks your permission before the app can use your device's advertising identifier to track you across other companies' apps and websites. If you allow it, ads may be personalized. If you don't, you'll still see ads, but they won't be based on tracking.
Where the law requires it (for example in the UK), Google asks for your consent first, and you can change your answer any time under Privacy Choices in the app's settings. Google's use of this data is covered by Google's privacy policy for partner apps. Buying "Remove Ads" turns ads off.
Game Center
If you're signed in to Game Center, your score and Game Center nickname are sent to Apple to show on the leaderboard. This is handled by Apple under Apple's privacy policy; we don't receive your Apple ID.
Purchases
In-app purchases are processed entirely by Apple. We never see your payment details. The app only learns whether a purchase is active so it can unlock the feature.
Children
Our apps are not directed to children under 13, and we don't knowingly collect personal information from children.
Changes and contact
If this policy changes, we'll update this page and the date below. Questions? Email support@aiosa.app.
