EUR USD Tracker · Holger Sochau · Last updated: March 20, 2026

      Short version: EUR USD Tracker does not collect, transmit, or share any personal data. Everything you enter stays on your device.
    

1. Who We Are

EUR USD Tracker is developed and published by Holger Sochau, a sole trader (Einzelunternehmer) based in Bottrop, Germany. Contact: holger.sochau@gmail.com

2. Data We Collect

We collect no personal data.

EUR USD Tracker does not require you to create an account, sign in, or provide any personal information to use the app.

3. Data Stored on Your Device

All information you enter into the app — including trades, account balance, notes, and settings — is stored exclusively on your device using your device's local storage. This data:

Never leaves your device
Is never transmitted to any server
Is never shared with any third party
Is not accessible to us in any way

If you delete the app, all locally stored data is permanently deleted.

4. Live Exchange Rate Data

The app optionally fetches live EUR/USD exchange rate data from a third-party financial data provider (Twelve Data). This request contains no personal information — it is a standard market data request identical to loading a webpage. No user data is sent as part of this request.

5. Subscriptions and Payments

EUR USD Tracker offers optional paid subscriptions. All subscription management, billing, and payment processing is handled exclusively by Apple through the App Store. We do not receive, store, or process your payment information. For details on how Apple handles your payment data, please refer to Apple's Privacy Policy at apple.com/legal/privacy.

6. Analytics and Tracking

EUR USD Tracker does not use any analytics tools, advertising SDKs, or tracking technologies. We do not track your behaviour inside the app or across other apps and websites.

7. Third-Party Services

The app interacts with the following external services:

Twelve Data — live EUR/USD price feed (no personal data transmitted)
Apple App Store — subscription and payment processing

No other third-party services, SDKs, or frameworks are used.

8. Children's Privacy

EUR USD Tracker is not directed at children under the age of 13. We do not knowingly collect any information from children.

9. Your Rights (GDPR)

Because we do not collect any personal data, there is no personal data for us to provide, correct, or delete. If you have any questions about your rights under the General Data Protection Regulation (GDPR), please contact us at holger.sochau@gmail.com.

10. Changes to This Policy
