Which data does the app process?

  • Your training data (runs, results, settings, test date, own questions) is stored locally on your device only.
  • There is no account, no sign-up, no cloud synchronisation and no analytics or tracking services.
  • No data is transmitted to us or to third parties.

Speech output

The read-aloud function of the audio modules uses your device’s built-in speech output. No data is sent to us or third parties.

Notifications

Optional training reminders are scheduled entirely locally on your device. You can disable them at any time in the app or in your device settings.

In-app purchases

The Pro unlock is processed by Apple’s App Store or Google’s Google Play. To verify and manage purchases the app uses RevenueCat (RevenueCat, Inc., USA). An anonymous, randomly generated user ID, App Store or Google Play receipts, device type, app version and language are transmitted. No name, email address or payment details are transmitted to us or to RevenueCat; payment is handled exclusively via your Apple ID or Google account. More information: revenuecat.com/privacy.

Export and import

You can export your data as a file and import it again. This file only leaves your device if you share it yourself.

Deletion

“Delete all data” in the profile removes all locally stored data. Deleting the app also removes all data.

The website is hosted by Vercel Inc. (USA). When you visit, technically necessary connection data (e.g. IP address, time, page requested) is processed briefly in server logs. For audience measurement we use Vercel Web Analytics, which works without cookies and does not build cross-device profiles. Some images are loaded from the image service Pexels (images.pexels.com); your IP address is transmitted to Pexels in the process. Fonts are loaded from Google Fonts (Google Ireland Ltd.); here too the IP address is transmitted to Google. No cookies are set and no tracking takes place.

Some blog articles embed YouTube videos (provider: Google Ireland Ltd.). They only load once you press play – before that there is no connection to YouTube. Pressing play loads the video in privacy-enhanced mode (youtube-nocookie.com); your IP address and technical data are then transmitted to YouTube/Google, and YouTube may use cookies or local storage. Google's privacy policy applies.

Your rights

Since we do not store any personal data, there is no data held by us to which access, rectification or erasure could apply. If you have questions, you can contact the address above at any time.

Note

DLR Test Trainer is an independent preparation app and is not affiliated with the German Aerospace Center (DLR).
