Privacy Policy
Last updated: April 2026
Your privacy matters to us. This policy explains how G3 HVAC PrepBOX handles your information.
All quiz progress — including answers, test scores, study streak, and settings — is stored locally on your device and is permanently deleted when you uninstall the app.
We do not collect:
When you use the Contact Us form, your message is drafted and sent through your device's own email application. Your email address and message are received by our support team at SupportG3@proton.me and used solely to respond to your request. Support correspondence may be retained for a reasonable period for quality purposes. No data from this exchange is stored within the app itself.
If you choose to enable study reminders, notifications are scheduled locally on your device using the operating system's notification service. No notification content or scheduling data is sent to any external server.
The app includes bundled PDF study materials. When you open a PDF, it is loaded from the app's own files. No files are uploaded or transmitted anywhere without your action.
This app uses RevenueCat to manage in-app subscriptions. When you make or restore a purchase, RevenueCat receives an anonymous app user ID, your device platform (Android or iOS), and subscription status from the app store. RevenueCat does not receive your name, email address, or payment card information — payment data is handled exclusively by Google Play or the Apple App Store. RevenueCat's privacy policy is available at revenuecat.com/privacy.
All payment transactions are processed by Google Play (Android) or the Apple App Store (iOS). We do not receive, store, or have access to your payment information. Subscription transactions are subject to Google's and Apple's respective privacy policies.
This app is distributed through the Apple App Store and Google Play. These platforms may collect certain information — such as download history and device information — under their own privacy policies, which are independent of ours.
This app is not directed at children under the age of 13. We do not knowingly collect information from children under 13.
We may update this privacy policy as the app evolves. We encourage you to review it periodically. Continued use of the app constitutes acceptance of any changes.
If you have questions about this privacy policy, please use the in-app Contact Us form or email us at SupportG3@proton.me.
