Privacy Policy
1. Data protection at a glance
Deutsch Lernen is a PWA (Progressive Web App) for language education. Data protection is of great importance to us. This privacy policy explains which data we collect and how we use it.
Controller
The controller within the meaning of the General Data Protection Regulation (GDPR) is:
2. General information
The following information provides a simple overview of what happens to your personal data when you visit our website. Personal data is all data with which you can be personally identified.
3. Collection and processing of personal data
- User accounts: To use the service, you may require a user account with an email address
- Learning progress: Your learning activities are stored to track your progress
- Device permissions: Optionally, you can grant us access to the microphone, camera, or GPS
- Usage data: We collect anonymous data regarding app usage and error reports
4. Permissions
This app optionally requires the following device permissions:
- Geolocation: For location-based dialogues (optional, can be disabled)
- Microphone: For voice input and pronunciation exercises (optional)
- Camera: For image translations using OCR (optional)
- Notifications: For reminders and information regarding your learning activities (optional)
You can disable all permissions in the iOS/Android settings. The app will continue to function without these permissions.
4a. Offers from your region
Only if you activate 'Offers from my region' in the settings (consent pursuant to Art. 6(1)(a) GDPR and § 25 TDDDG), we determine your region (postal code, city, federal state) roughly from your location. Only this region is stored, not exact coordinates. We use this exclusively to display relevant proprietary advertisements and partner offers (e.g., language schools, banks) within the app.
- Location and region are not shared with advertising or affiliate partners
- Partner links contain only an anonymous click ID, no user ID
- There is no tracking across apps or websites of other providers
- You may withdraw your consent at any time in the settings; the stored region will then be deleted
4b. Push notifications (OneSignal)
If you allow push notifications, the app sends reminders and notifications about your learning activities (e.g., vocabulary reminders, wake-up calls, appointment reminders, daily questions, and news) via the push notification service OneSignal. Enabling this is voluntary: the app is fully usable without push notifications.
- Processed data: Device identifier (push token) of your device, your app user ID for associating messages, device information (e.g., operating system), as well as timestamps of delivery
- Purpose: Delivery of learning reminders and app notifications; there is no advertising and no tracking across apps or websites of other providers
- Involved services: OneSignal (dispatch) as well as the delivery systems of Apple (APNs) or Google (Firebase Cloud Messaging) for your operating system
- Legal basis: Your voluntary consent (Art. 6(1)(a) GDPR)
- Withdrawal: You can disable notifications at any time in the app or device settings; uninstallation of the app automatically ends the device registration
4c. TikTok (Social media publication)
For the publication of their own learning and promotional videos, the app operator connects their own TikTok account via the official TikTok interface (Content Posting API). This is a purely administrative function: end-user accounts are not linked to TikTok.
- Processed data: Access token of the connected operator account, uploaded videos with title, description, and hashtags, as well as public account information (e.g., display name)
- Purpose: Automated upload of videos created by the operator to the operator's own TikTok channel
- Legal basis: Legitimate interest of the operator in operating their own social media channel (Art. 6(1)(f) GDPR)
- No personal data of app users is transmitted to TikTok
- Further information: TikTok Privacy Policy (https://www.tiktok.com/legal/page/row/privacy-policy/row)
5. Storage of data
- Server-side: Email, user profile, learning history
- Locally: Cache for offline functionality (IndexedDB, LocalStorage)
- You can delete your account and all associated data at any time
6. Cookies and similar technologies
We use cookies and LocalStorage to:
- Keep you logged in
- Save your preferences
- Improve app performance
- Enable offline functionality
7. Third-party providers
This app may use external services:
- Base44: Backend-as-a-Service Platform
- Google APIs (optional, for social login)
- Stripe (optional, for payments)
- OneSignal (optional, for push notifications)
- TikTok (optional, social media publication by the operator, see section 4c)
Please note the privacy policies of these services.
