Math Kingdom Adventure Privacy Policy

Last updated: August 29, 2026

This Privacy Policy explains how Math Kingdom Adventure handles information. The app is a children's arithmetic learning game with addition, subtraction, multiplication, division, rewards, sounds, local progress, optional Premium, and advertising.

Short version: the app is designed for children, does not require an account, does not include chat, stores gameplay progress on the device, may show child-directed Google AdMob interstitial ads after a task is completed, and does not show ads to Premium users.

Math Kingdom Adventure is designed to work without creating an online account. The app may store the following information locally on the device:

• game progress, completed lessons and daily tasks, stars, coins, level, and XP
• language, sound, music, and display preferences
• premium / ads-removed status restored from Apple or Google Play

This local gameplay data is used to continue the child's learning experience. We do not operate an account server that stores a child's name, email, or profile.

Math Kingdom Adventure is made for children and families. We do not knowingly collect a child's personal contact information through the app. The app does not include public profiles, direct messaging, social posting, open chat, or user-generated content sharing.

The app is configured for child-directed advertising treatment. We do not use the app to sell children's personal information.

The free version of Math Kingdom Adventure may show full-screen interstitial ads provided by Google AdMob.

• Ads appear only after a lesson or daily task is finished, when the child taps Continue, Next, or Done.
• Ads are not shown during questions, lessons, or other gameplay.
• If loading an ad fails or no ad is available, the child continues immediately.
• Premium users do not see ads.
• The app requests child-directed treatment, a maximum ad content rating of G, and non-personalized ads.
• The app is not designed for interest-based or behavioral advertising.

Google AdMob may process technical information needed to request, select, and display ads, such as device type, app identifier, approximate general location derived from IP address, and advertising-related signals, according to Google's policies for child-directed apps. We do not use advertising to build a personal profile of a child for interest-based ads.

Google's own practices are described in the Google Privacy Policy and AdMob & Ad Manager policies for families.

Optional Premium (monthly, yearly, or lifetime) can remove ads and unlock paid learning content. Payments are processed by Apple App Store or Google Play. We do not receive full payment card numbers. Purchase restoration uses the store account on the device.

We do not sell personal data. We do not share children's contact information with data brokers. Third parties involved in providing the app may include:

• Google AdMob, for child-directed interstitial ads in the free version
• Apple App Store and Google Play, for installing the app and processing in-app purchases

The app uses internet access to load ads and to communicate with Apple or Google for purchases. The app uses audio playback for learning feedback and reward sounds. The app does not require camera, microphone recording, contacts, or precise location for core math practice.

We do not ask children to enable App Tracking Transparency / cross-app tracking. Advertising is configured as non-personalized and child-directed.

For Google Play Data safety and Apple privacy labels, families should know:

• App activity such as progress, coins, stars, and settings is stored on the device.
• Advertising data may be processed by Google AdMob to show child-suitable ads.
• Purchase history is handled by Apple or Google, not by a Contact Echoo payment server.
• We do not collect account credentials, photos, contacts, or precise location in the app.

Gameplay progress is stored on the device. Parents can remove local app data by deleting the app or clearing app storage through device settings. This may reset coins, stars, completed tasks, and preferences. Ad-related data handled by Google is retained according to Google's policies.
