FlashDeutsch Privacy Policy

1. Who this policy applies to

This Privacy Policy applies to the FlashDeutsch Android application and the GitHub Pages website published for the project at farzadj.github.io/FlashDeutsch.

App package name: com.flashdeutsch.

2. What FlashDeutsch stores on your device

FlashDeutsch is designed to work offline after installation. The app stores most study information locally on your device, including:

study progress and session history
favorites and hard-card markers
settings such as theme, language, speech, and study preferences
milestone progress and locally unlocked milestones
user-created flashcards and local edits to bundled cards

This local data is stored using on-device app storage technologies such as Room and DataStore.

3. Data FlashDeutsch does not require

FlashDeutsch does not require a custom backend account to study. The app does not depend on a personal login system to use its core flashcard features.

4. Advertising

FlashDeutsch may use Google Mobile Ads, including rewarded or interstitial ad flows, depending on the feature and app configuration.

If ads are shown, Google and its partners may process device and advertising-related information according to Google's own privacy terms and consent flows.

The app also uses Google's User Messaging Platform (UMP) for consent where required.

5. Subscriptions and payments

FlashDeutsch includes a Google Play Billing integration for an optional subscription product such as flashdeutsch_pro_monthly.

Payments, subscription status, and transaction handling are processed by Google Play, not by a custom FlashDeutsch payment server.

6. Speech and device services

The app can use device text-to-speech services to read flashcard content aloud. Speech playback is handled through services available on your Android device.

FlashDeutsch may request speech output for German and, depending on the device, other supported learning languages.

7. Network usage

Although FlashDeutsch is offline-first, some app flows may use the network for:

Google Mobile Ads
consent handling
Google Play Billing and subscription validation through Google Play
app distribution and updates through Google Play

8. Third-party services

FlashDeutsch may rely on the following third-party services:

Google Play Services / Google Mobile Ads
Google User Messaging Platform (UMP)
Google Play Billing
GitHub Pages for this website

These services operate under their own privacy policies.

9. Website hosting

The FlashDeutsch website is hosted on GitHub Pages. Standard web-hosting logs or analytics handled by GitHub may apply when you visit the website.

10. Data retention and removal

Because most app data is stored locally, uninstalling the app or clearing app storage can remove that local data from your device.

User-created cards and local edits are stored on-device unless future sync features are introduced.

11. Your choices

You can change app settings such as language, theme, speech, and learning preferences inside the app.
You can reset progress from the app if that feature is enabled in settings.
You can choose whether to subscribe for Pro access through Google Play.
You can choose whether to engage with rewarded ad flows where they are offered.

12. Children's privacy

FlashDeutsch is a language-learning app. If children use the app, parents or guardians should review ad, subscription, and device privacy settings before use.

13. Changes to this policy

This Privacy Policy may be updated when the app's features, data flows, or third-party services change. The updated version will be published on this page.
