The app provides practice questions and study tools for the Certified Maintenance & Reliability Professional (CMRP) exam. If you have any questions, you can contact us at tcbaytan@gmail.com.
2. Information We Collect
a) Information you provide
You can use the app without creating an account. If you contact us via email, we use your email address and the information in your message only to respond and provide support.
b) Automatically collected information
The app uses third-party services that may collect limited information for app functionality, advertising, fraud prevention, analytics, and purchase validation.

3. Advertising (Google AdMob)
CMRP Exam Prep uses Google AdMob to show ads, including rewarded ads (e.g., earning credits by watching an ad). AdMob may collect data to serve ads, measure performance, limit ad frequency, prevent fraud, and comply with legal requirements.
Depending on your device and settings, AdMob may use:
- Android: Advertising ID (AAID)
- iOS: Identifier for Advertisers (IDFA) only if you allow tracking (App Tracking Transparency)
If you do not allow tracking on iOS, ads may still be shown using contextual information (e.g., app content and general device info).

4. In-App Purchases (RevenueCat)
We use RevenueCat to manage in-app purchases such as credit packs and/or subscriptions (if available). RevenueCat processes purchase-related data to validate transactions, prevent fraud, and manage entitlements (e.g., restoring purchases).
