Your study.
Your privacy.

1. About this policy

Lumidev publishes CDL Practice Test: HAUL. This policy covers the Android app identified above and this privacy information page. HAUL is an independent commercial-driver study tool. It does not require an account and has no developer-operated cloud service for storing your study progress.

The production edition (version 1.8) uses Google advertising to help fund the app. Requests use non-personalized ad settings and follow applicable privacy choices. Earlier closed-test builds use Google demo advertising; version 1.7 was an ads-off candidate. Demo ads do not generate publisher revenue. The practices below describe versions that include the Google advertising SDKs.

2. Information stored for your study

The app stores your study settings, selected study path, answers, confidence selections, bookmarks, planned test date, saved sessions, practice history and progress on your device. This information supports practice sessions, review suggestions, progress views and resuming your place.

HAUL does not send this study record to a developer-operated server. You can export a JSON backup through your chosen device storage or sharing service and import it later. That export goes where you choose; the recipient or storage provider has its own privacy practices. Exported files may contain your study history and settings.

A separate local record stores advertising frequency counters, recent completed session identifiers and the expiry time of a rewarded pause in ads. These values manage ad timing and the temporary reward. They are not part of exported study backups.

3. Google's advertising services

The Android app integrates Google Mobile Ads and Google's User Messaging Platform (UMP). Depending on configuration and your choices, Google's SDK may process your IP address and approximate location inferred from it, device or account identifiers, product and advertising interactions, and diagnostic and performance information, including crash logs and other app-performance data. Google uses SDK data for advertising, analytics and fraud prevention. Google describes encrypting SDK data in transit using TLS.

Google's data practices, retention and controls are explained in the Mobile Ads SDK data disclosure and Google Privacy Policy. Demo or non-personalized advertisements should not be understood as a promise that no information is processed.

Ad requests wait until UMP permits them. Where applicable, Google presents privacy messages. You can revisit available privacy options through Settings → Ads & privacy. Availability depends on your region and the messages configured for the app. Android also provides advertising identifier and advertising privacy controls; the names and locations vary by Android version.

4. Device services and external links

Optional read-aloud study uses the installed text-to-speech service. Study text is passed to that service when you use the feature. Whether it uses downloaded voices or an online service depends on the voice provider and your device settings. Consult your voice provider's privacy information for its handling of requests.

Official manual and reference links open external websites. Those providers receive your browser requests and apply their own policies. HAUL does not request access to your contacts, camera, microphone or precise device location.

If you contact support, we receive the email address and information you choose to send to answer your request. The support mailbox uses Gmail; Google’s Privacy Policy applies to that service. This page is hosted on GitHub Pages; the GitHub Privacy Statement describes its hosting practices. This policy page does not include developer-installed analytics or advertising scripts. The hosting service may process routine request information needed to deliver and secure the page.

5. Your choices

• Study without creating an account.
• Export a study backup from the app's settings, and manage or delete exported copies in the locations you chose.
• Reset study progress in Settings. This resets the study record; it does not reset the separate ad frequency and reward record.
• Clear the app's storage through Android settings to remove local study data and local ad records, or uninstall the app.
• Use available options in Settings → Ads & privacy and Android's advertising privacy controls.
• Choose whether to use read-aloud study or open external reference links.

Clearing local data does not instruct Google or a storage provider to delete records they independently process. Use the relevant provider's controls or contact channels for those records. There is no HAUL account to close.

6. Retention and security

Local study information remains until you reset it, clear app storage or uninstall the app. Separate local advertising records remain until cleared with app storage or removed by uninstalling. Exported backups remain in your selected locations until you or the relevant provider delete them. Google determines retention for information it processes under its own policies; HAUL does not set a universal retention period for Google's records.

The app uses its private device storage for local records. Its Android configuration disables cleartext network traffic and Android automatic app backup. Device security and access controls still matter. JSON backups you export are not encrypted by HAUL; keep them in a location you trust. No storage or transmission method can be guaranteed completely secure.

7. Intended audience

HAUL is designed for people preparing for commercial-driver licensing and is not designed as a child-directed service. If you believe a child has supplied information to a third-party service through the app, use the privacy contact below and that provider's relevant reporting channel.

8. Privacy contact and updates

For questions about this app or this policy, or to make an applicable privacy request, contact HAUL support at lumidev.support@gmail.com. Please do not send passwords or complete exported study backups in your initial message.

HAUL cannot retrieve device-only study records remotely; the local controls above let you manage those records. Requests relating to information held by Google or another independent provider should also be directed to that provider through its privacy controls.

Changes to the app's data practices will be reflected in an updated policy with a revised date. Review this page when a new version introduces new services or features.
