2. Introduction
WordTracker is an app for managing and tracking writing projects, available for iOS, Android, and macOS. The protection of your personal data is important to us. This privacy policy informs you about the processing of your data when using our app.
3. Data Processing
3.1 Local Data Storage
WordTracker stores all your data primarily locally on your device. We collect and process the following data:
- Writing Statistics: Word count, date and time of entries
- Project Information: Project name, description, color, icon, goals
- App Settings: Theme settings, notification settings
- Premium Status: Information about in-app purchases or redeemed vouchers
Important: This data is stored primarily locally on your device. Transmission to external servers only occurs within the scope of the functions described below.
3.2 Cloud Synchronization (optional, Premium)
Depending on the platform, you can optionally sync your data to the cloud:
iOS/macOS – iCloud Sync:
If you have enabled iCloud for this app in your iOS or macOS settings, your data will be synchronized via your iCloud. This is subject to Apple’s privacy policy: https://www.apple.com/legal/privacy/
All Platforms – Cloud API Sync (Google Drive, Dropbox, OneDrive):
On iOS and macOS as an alternative or supplement to iCloud, and on Android as the primary cloud sync option, you can synchronize your data via one of the following cloud providers:
- Google Drive: Sign in with your Google account. Your data is stored in a private app folder. Privacy policy: https://policies.google.com/privacy
- Dropbox: Sign in with your Dropbox account. Privacy policy: https://www.dropbox.com/privacy
- OneDrive: Sign in with your Microsoft account. Privacy policy: https://privacy.microsoft.com/en-us/privacystatement
Only one cloud provider can be active at a time. Synchronization occurs automatically and includes all projects, entries, genres, and settings. When signing in, your email address and display name are stored locally and used to display the connected account. Authentication is handled via OAuth – your credentials are not stored in the app. Synchronization occurs exclusively between your own devices.
3.3 In-App Purchases
iOS: If you purchase premium features via in-app purchase, Apple processes payment data according to their privacy policy. We only receive an anonymous transaction confirmation.
Android: If you purchase premium features via Google Play, Google processes payment data. To verify the purchase, the following data is transmitted to our server (api.todisco.de):
- App package name
- Product ID
- Purchase token
- Device ID (Android ID)
This data is used exclusively to verify purchase entitlement.
3.4 Device ID (Android only)
On Android, the device ID (Android ID) is collected and used in the following cases:
- Purchase verification: Transmitted to our server to verify premium purchases
- Promo codes: Stored in Google Firestore to prevent multiple redemptions
The device ID is not used for tracking or advertising purposes.
3.5 Notifications
When you enable notifications, they are created locally on your device. No data is sent to external push services, as the app uses only local notifications.
3.6 Error Monitoring with Sentry
WordTracker uses Sentry (www.sentry.io) to detect and fix errors.
iOS: Error monitoring is disabled by default and must be explicitly enabled by you in the settings (opt-in).
Android: Error monitoring is enabled by default. You can disable it at any time in the app settings (opt-out).
When active, the following data is transmitted to Sentry:
- Error reports and app crashes
- Performance data (load times, transactions)
- Technical device information (device type, operating system version)
- App version and time of error
- Session data (app starts, session duration)
- No personally identifiable information such as names, emails, or your writing data
You can disable Sentry at any time in the app settings. After deactivation, no further data will be transmitted.

3.7 OCR/Camera Function (iOS, Premium)
WordTracker offers the ability to photograph text and automatically count the words. Text recognition is performed entirely locally on your device using Apple’s Vision Framework. No images or recognized text are transmitted to external servers.
3.8 Automatic Backups (Premium)
WordTracker can create daily automatic backups of your data. These backups are stored locally in a folder of your choice on your device (CSV or JSON format). A maximum of 5 backups are retained; older ones are automatically deleted. No backup data is transmitted to external servers.
