MilPrep is a free study app for U.S. military rank and knowledge practice, made by aiworkisleep (Kylan Hill). This policy explains what data the app handles.
The short version: nothing leaves your device.
MilPrep does not collect, transmit, or share any personal information.
MilPrep does not connect to the internet. It does not request the INTERNET permission.
MilPrep contains no advertisements, no trackers, no analytics, and no third-party SDKs.
MilPrep does not require an account, sign-in, or registration.
MilPrep is free, with no purchases of any kind.
MilPrep saves a small amount of data on your device so you can pick up where you left off:
Your best, most recent, and total scores for each study mode and branch
Your progress through any quiz you haven't finished (which question you're on and your running score)
This data is stored only on your device using Android's standard local storage (Jetpack DataStore). It is never sent anywhere. The developer cannot see it.
MilPrep does not collect, request, or have access to:
Your name, email address, or any account information
Your location
Your contacts, photos, files, microphone, camera, or other device sensors
Crash reports, diagnostics, or analytics
Device identifiers (advertising ID, IMEI, MAC address, etc.)
Any other information that could identify you
MilPrep requests no runtime permissions. It does not request internet access, storage, location, or any other sensitive permission.
The About screen includes links to the developer's website (aiworkisleep.com) and LinkedIn profile. Tapping these links opens them in your device's web browser, which is a separate app subject to its own privacy practices. MilPrep itself does not make any network requests.
MilPrep is suitable for users of all ages. Because the app does not collect any personal information from anyone, it complies with the U.S. Children's Online Privacy Protection Act (COPPA), the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and similar laws — there is no personal data of any user, child or adult, to protect, share, or sell.
To delete everything MilPrep has stored on your device, do either of the following:
Clear the app's data from Android Settings → Apps → MilPrep → Storage → Clear data, or
Uninstall the app
Either action permanently removes all scores and quiz progress from your device. Because no data leaves your device, no further cleanup is needed.
MilPrep does not share data with anyone, because it has no data to share. It uses no third-party analytics services, advertising networks, crash reporting tools, or cloud storage providers.
If this policy changes, the updated version will be posted at the same URL where you found this one, with a new "Effective date" at the top. Material changes will also be noted in the app's release notes on the Google Play Store.
