Backflow Tester Prep · Last updated September 28, 2026

Backflow Tester Prep is an independent study app with practice questions for the exam, each with a written explanation.

What we collect

Nothing about you. There is no account, and we do not ask for your name, email, or any identifying detail.

What stays on your device

Your answered questions, misses, bookmarks and scores are written only to your device's local storage — never transmitted to us or anyone else. Deleting the app removes it all.

Ads and analytics

None are present: no advertising SDKs, no third-party analytics, no tracking identifiers.

Free use and purchases

You can practice up to 15 questions free every day. An optional subscription removes that daily limit; it is processed by Apple through the App Store under Apple's own terms, and we never see your payment information.

Children and younger learners

The app is for candidates preparing for a professional credential and is not directed to children.
