Purchases and Pro access

How do I restore a previous purchase?

Open the app's Settings tab and tap Restore Purchases in the Pro access section. Use the same Apple ID that made the purchase and keep the device connected to the internet. The paywall also includes a Restore Purchases button.

Do Pro plans renew automatically?

No. Pro is offered as a non-renewing subscription for one month, three months, or one year. You pay once for the selected access period. It does not auto-renew, and you can purchase another period when access ends.

Who handles payment and refunds?

Purchases are processed by Apple through your Apple ID. The app does not collect your full payment card number. Refund eligibility and requests are handled through Apple.

Practice and exam sessions

What topics does the app cover?

Universal Core modules only: General Knowledge, Air Brakes, and Combination Vehicles. Endorsements such as HazMat, Tanker, Passenger, or School Bus are not included in this version.

Can I continue an unfinished session?

Practice and exam drafts are saved when you leave a session or the app enters the background. Use the continue card on the Practice or Exam tab. Discarding a draft cannot be undone.

How does the practice pass mark work?

Core practice exams use a three-choice format and an 80% practice pass mark. App results are study aids only and are not official DMV results.

Progress and data

Where is my study progress stored?

Progress is stored locally on your device. The current version does not provide an account or cloud progress-sync service. Deleting the app or erasing device data may remove your progress.

How do I reset practice progress?

Go to Settings → Data → Reset practice progress (wording may vary slightly by version). This clears study progress, missed items, bookmarks, streaks, and exam history. Your purchase status is not reset.

Study reminders

Why am I not receiving reminders?

Enable study reminders in the app Settings and allow notifications when iOS asks. Also check notification permission for CDL Exam Prep in the iOS Settings app. Reminders are local notifications and do not require an account.
