Website privacy

Effective October 2, 2026. CDL Prep Hero is operated by Evergreen Comply, LLC. This page describes the website; the app has its own privacy information. Visit our about page for more about our service.

Microsoft Edge extension

The daily-question browser extension has a separate extension privacy policy. It does not collect answers or browsing data.

Free practice

You can use practice questions without an account. Your choices and score are held in the page while you practice; we do not send individual answers through our analytics events.

App launch email list

If you joined, we store your email, signup time, and the page where you joined using our service provider Supabase. We use your email for the promised app launch notification. We do not sell your email. Email support@evergreencomply.com to ask about your signup or request deletion.

Optional Google Analytics

When configured, Google Analytics loads only if you choose "Allow analytics." It measures page visits, quiz starts and completions, print-dialog requests, successful waitlist signups, and clicks on official app-store links. Quiz events include the practice topic, mode, number of questions, and total correct—not individual answers. Waitlist analytics does not include your email. Store-link events include only the store and link placement—not your account or the destination URL. A click is not proof of an install or purchase.

Our events omit URL query strings and fragments and reduce referring URLs to their origin. Google Analytics uses cookies and processes technical information about your browser and device. We disable advertising signals, personalization and enhanced automatic measurement for this setup. Analytics covers consenting visits only, so reports will not count everyone.

We store your analytics preference in this browser. You can withdraw it below. We respect Global Privacy Control and Do Not Track signals by leaving analytics off. Withdrawal stops further collection through our integration and removes this site's Google Analytics cookies; it does not automatically erase data already processed by Google.

See Google's privacy policy for its handling of data.

Hosting and support

Vercel hosts this website and processes technical requests to deliver it and help protect the service. If you email support, we receive what you send. Please do not send license numbers, medical information, or other sensitive details with a correction request.

Questions and requests

Contact support@evergreencomply.com for website privacy questions, access or deletion requests. We may need to verify that a request concerns your own information. See our study guides for CDL test preparation tips.
