Mental Math Champion
Privacy Policy
Stealth Launch, LLC operates Mental Math Champion. This policy explains what information the app relates to and how it is handled.
Summary
- No Stealth Launch account is required to play.
- Progress, statistics, and achievements are stored on your device.
- We do not run a first-party analytics SDK in version 1.0.
- The free tier shows advertisements through Google AdMob (interstitial and rewarded ads). Premium subscribers do not see ads.
- Optional leaderboards use Apple Game Center or Google Play Games.
- Premium purchases are processed by Apple, Google, and RevenueCat. We do not receive or store your payment card details.
Information stored on your device
The app may store locally (for example via on-device storage):
- Training / story / competition / Fog Run progress
- Statistics, streaks, and achievements
- Settings preferences
- Relic discovery / Fog Run personal bests
- Local daily Fog Run counters (including rewarded-ad bonuses)
This data stays on your device unless you clear app data or uninstall. We do not operate a Stealth Launch cloud account that syncs this progress in v1.
Advertising (Google AdMob)
If you play without Premium, Mental Math Champion displays ads from Google AdMob, including:
- Interstitial ads after certain Story stages, Training sessions, Competition runs, and Fog Run map returns
- Rewarded ads you may choose to watch for an extra Fog Run after the free daily limit
Google and its partners may collect or receive information such as:
- Device and advertising identifiers (for example IDFA / AAID, subject to your OS permissions)
- IP address and general device / network information
- Ad interaction and performance data
That processing is governed by Google’s privacy policies and any consent / tracking prompts required by Apple or Google on your device. Stealth Launch uses AdMob to support the free tier; we do not sell your personal information. Subscribing to Premium removes ads in the app.
You can also limit ad tracking in your device settings (for example Apple’s App Tracking Transparency / Personalized Ads controls, or Google Play’s ads settings).
Game Center and Google Play Games
If you use leaderboards, Apple or Google may process:
- Your Game Center / Play Games player identity
- Scores you submit from Competition and Fog Run
That processing is governed by Apple’s and Google’s own privacy policies. Stealth Launch uses these services to show competitive rankings; we do not build a separate social network or profile system inside the app.
Purchases and subscriptions
Premium is sold as an auto-renewable subscription through the App Store or Google Play. Payment details are handled by Apple or Google. We use RevenueCat to verify entitlements (whether Premium is active). We do not store full payment card numbers.
Children
Mental Math Champion is designed to be family-friendly. We do not require account creation. The free version displays ads via Google AdMob. Parents and guardians who prefer an ad-free experience can use Premium, and should review device Game Center / Play Games, purchase, and advertising settings.
Data sharing
We do not sell personal information. Limited data may be processed by:
- Apple / Google (store distribution, Game Center / Play Games, billing)
- Google AdMob (advertising on the free tier)
- RevenueCat (subscription entitlement status)
Your choices
- Uninstalling the app removes on-device progress.
- Manage Game Center / Play Games in system settings.
- Manage or cancel Premium in your Apple ID or Google Play subscription settings.
- Restore purchases in the app Settings when available.
- Limit ad personalization in your device / Google settings where available.
