HazMat Prep – Privacy Policy

Last updated: November 10, 2026

HazMat Prep ("the app") is a study app for the CDL Hazardous Materials endorsement knowledge test, published by Uru-Apps. This policy explains what data the app uses and why.

What the app stores on your device

Your answers, scores, study progress and settings (read aloud, sound, vibration, theme) are saved only on your device. We do not run servers that receive this data, and you do not need an account. Uninstalling the app deletes it.

Read aloud

The read-aloud feature uses your phone's built-in text-to-speech engine. The app sends no audio and no text to us.

Advertising

The app shows ads from Google AdMob. To show and measure ads, Google may collect information such as your device's advertising ID, IP address, device model and operating system, and how you interact with ads. Google uses this data as described in its policy: How Google uses information from sites or apps that use its services.

If you are in the European Economic Area, the UK or Switzerland, the app asks for your consent before personalised ads are shown. You can change your choice at any time in the app under Settings › Privacy options. You can also reset or delete your advertising ID in your Android settings.

Data we do not collect

We do not collect your name, email, contacts, location, driver's license details or any other personal information. The app has no analytics of its own and no in-app purchases.

Not a government app

HazMat Prep is an independent study tool. It is not affiliated with, endorsed by, or connected to the DMV or any state licensing agency, the FMCSA, PHMSA, the US Department of Transportation or the TSA. The questions are written by us from the public federal Hazardous Materials Regulations (49 CFR, available at ecfr.gov). Always study your state's official CDL manual too.

Children

The app is meant for adults preparing for a commercial driver's license and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes and contact

If this policy changes, we will update this page and its date. Questions: sadoqyoussef23@gmail.com
