What the app does

This app is an educational game for learning numbers, designed for children ages 2–6. It does not require account creation, sign-in, or any personal information to play.

Advertising

The app uses the Google Mobile Ads SDK (AdMob) to show rewarded video and interstitial ads only — never banner ads. All ad requests are made under Google's child-directed treatment and under-age-of-consent settings, so ads are served on a contextual basis only, with no behavioral or interest-based targeting. Google and its partners may process device and network information (such as the advertising identifier) that is needed to deliver ads, prevent fraud, measure ad performance, and maintain the ads service.

Children ages 2–3 are never shown ads directly; any rewarded-ad offer for that age group is placed behind a Parent Gate (a simple math challenge) so only an adult can trigger it.

In-app purchases

This app does not offer any in-app purchases or subscriptions. There is no ad-removal purchase or any other paid feature.

On-device preferences

The app stores a small amount of data locally on the device (using MMKV, an on-device storage library), including learning progress, star ratings, age-mode selection, and sound/music settings. This data stays on the device, is never transmitted anywhere, and is used only to remember the player's preferences and progress.

External links

The app does not open any external links or web pages during gameplay. This privacy policy is reachable from the app's Settings screen.

What the app does not do

• No account registration or sign-in
• No user-generated content or uploads
• No collection of names, email addresses, photos, location, or other personal information
• No analytics, crash-reporting, or tracking SDKs of any kind
• No biometric data collection
• No in-app purchases of any kind

Children's privacy

This app is designed and directed at children and is operated in accordance with the Children's Online Privacy Protection Act (COPPA) and Google Play's Families Policy. It does not knowingly collect personal information from children. Advertising is limited to contextual, non-personalized ads served under Google's child-directed API settings, and settings that could affect a child's experience (such as changing age mode) are protected by a Parent Gate. Parents or guardians should review this policy and supervise device use.
