NumRush (“we”, “us”, “the app”) is a casual math puzzle game developed and operated by StudiosKMT (“the developer”). This Privacy Policy explains what data the app collects, why, and how it is used.
By installing or using NumRush you agree to the practices described in this policy.
The following data is stored locally on your device (via AsyncStorage). It never leaves your device unless you trigger a feature that explicitly requires it (e.g. an in-app purchase).
You can erase all of this data at any time by uninstalling the app or clearing app storage in your device settings.
NumRush integrates the following third-party SDKs. Each operates under its own privacy policy.
We use RevenueCat to process in-app purchases and manage premium subscriptions. RevenueCat receives your anonymous app user ID, your purchase receipts, and the product identifiers you buy.
Payments are processed by Apple (iOS) or Google (Android). The developer never receives your payment information.
If you have not purchased a premium subscription, the app shows ads via AppLovin MAX. AppLovin and its mediation partners may collect your advertising identifier (IDFA on iOS / Android Advertising ID), coarse location, device model, OS version, and ad interaction events to serve and measure ads.
On iOS, ads are only personalized if you grant tracking permission via Apple’s App Tracking Transparency (ATT) prompt. If you decline, ads are still shown but not personalized.
Local notifications (life regeneration, inactivity reminders) run entirely on your device via expo-notifications. No server-side push is used. No notification content is uploaded.
| Permission | Purpose | Required? |
|---|---|---|
| Push Notifications | Local reminders for life regeneration & inactivity | Optional |
| App Tracking Transparency (iOS) | Personalized ads via IDFA | Optional |
| Network access | RevenueCat, AppLovin ad delivery | Required |
You may revoke any optional permission at any time in your device settings.
NumRush does not knowingly collect personal information from children under 13 (or under the age of digital consent in your jurisdiction). The app is rated for general audiences and does not require account creation.
If you are in the EU, UK, or California, you have the right to:
