EPA 608 Prep is an exam prep app for the EPA Section 608 technician certification (refrigeration and air conditioning, United States). This policy explains, in plain language, what the app does with your data: almost nothing, and nothing leaves your phone.
EPA 608 Prep is an independent study tool. It is not affiliated with or endorsed by the U.S. Environmental Protection Agency (EPA) or any government body.
EPA 608 Prep has no account, no sign-up, and collects no personal data. No analytics, no trackers, no ads. Your quiz progress stays on your device. The only third party involved is the payment processor, and only if you choose to buy.
EPA 608 Prep works without an account. We never ask for your name, email, or any identifier. There is nothing to sign up for and nothing we could link to you.
Your scores, history, mock exam results, and weak points per section (Core, Type I, Type II and Type III) are stored locally on your device only. They are never uploaded, synced, or shared. Uninstalling the app deletes them permanently.
EPA 608 Prep requests no sensitive permissions: no camera, no location, no contacts, no files. It is a quiz app; it does not need them.
EPA 608 Prep offers a single one-time Pro purchase. Payments are processed by Google Play or the App Store and managed through RevenueCat, which receives the purchase transaction data needed to validate your purchase and uses an anonymous app identifier. The app itself collects no name and no email. We do not see or store your payment information; Google’s or Apple’s privacy policy applies to the transaction.
EPA 608 Prep is not directed at children under 13. We do not knowingly collect data from children. We do not collect data from anyone.
If this policy changes, the updated version will be posted at this address with a new effective date.
