CDL Practice Test — last updated: August 2026
The short version
There is no account and no sign-up. We do not ask for your name, email address or phone number, we do not run any server, and your study data never leaves your phone. The only third parties involved are the advertising and payment services described below.
Nothing that identifies you. The app has no registration, no login and no user profile. We do not collect your name, email address, phone number, contacts, photos or location.
Your answers, results, mistakes, saved questions, unlocked units, chosen state and language, daily goal, reminder times and theme preference are stored locally on your phone. The content of your study data is never uploaded — we cannot see which questions you got wrong. What does leave the device is the anonymous usage measurement described in section 5: counts and events, not your answers. If you delete the app, everything stored locally is gone.
The free version shows ads served by Google AdMob. To do this, Google may process your device's advertising identifier and technical data such as device type, coarse location derived from IP address, and ad interaction. This processing is carried out by Google under its own privacy policy, not by us; we receive only aggregate earnings figures and never see individual users.
On iOS, the system asks for your permission before any tracking. On Android and in regions where it applies, a consent form is shown. If you decline, the app works exactly the same and ads are simply not personalised.
Premium removes all advertising, and with it this processing.
If you buy Premium, the transaction is handled by Apple or Google and validated through RevenueCat. They receive an anonymous purchase identifier and your subscription status. We never see your card details — the payment happens entirely inside your store account, and we cannot access it.
The app records anonymous usage events — screens opened, sessions finished, purchases — through Google Analytics for Firebase. This tells us which parts of the app people actually use and whether our advertising is working. It is not tied to a name, an email address or an account, because the app has none of those.
If you decline tracking when the system asks, measurement is switched off rather than merely un-personalised. There is no crash-reporting SDK and no cloud database; your answers, results and progress are still stored only on your device and are never uploaded.
The app is intended for adults preparing for a commercial driver's licence (CDL) test and is not directed at children. We do not knowingly collect information from children, and we collect nothing that identifies any user by name.
We hold no account and nothing that names you, so there is no profile for us to export or correct. You control the rest from your device: reset your progress in Settings, change your tracking choice in your system settings — which also switches usage measurement off — and remove the app to erase all remaining local data.
If this ever changes — for example if a future version adds accounts or analytics — this page will be updated before that version ships, and the change will be visible here.
