Privacy Policy

Last updated: March 2026

We keep this simple: we collect as little as possible, store it securely in the EU, never sell it, and you can ask us to delete it at any time.

1. Who We Are

TradingBrief is a product of Mathonyx GmbH, a software company based in Germany. If you have any questions about this policy, contact us at hello@mathonyx.com.

2. What We Collect

We collect only what is necessary to run the app:

We do not collect passwords. Account access uses email-only authentication.

3. How We Use Your Data

We do not use your data for advertising, profiling, or any purpose beyond operating the app.

4. Where We Store Your Data

All user data is stored on AWS RDS in eu-west-1 (Ireland). Data is encrypted at rest and in transit. We do not transfer personal data outside the European Economic Area.

5. AI-Generated Briefings (Anthropic Claude)

Briefings are generated using the Anthropic Claude API. When a briefing is created, current market price data is sent to Anthropic's servers to generate the analysis. Your email address and personal identifiers are not included in these requests.

Anthropic processes this data under their own privacy policy and API usage terms. You can review Anthropic's policy at anthropic.com/privacy.

6. Payments and Subscriptions

All payments are handled entirely by Apple through the App Store. We never see, process, or store your card details or billing information. Apple's privacy policy governs how your payment data is handled.

We receive only a signal indicating whether your subscription is active or expired.

7. Analytics and Tracking

We use no third-party analytics, no tracking pixels, and no cookies. The app does not track your behaviour across other apps or websites.

8. Push Notifications

TradingBrief may send push notifications for briefing alerts. Push notifications are optional. You can enable or disable them at any time in iOS Settings → Notifications → TradingBrief.

9. Data Retention

We retain your data for as long as your account is active. If you request deletion, we will remove your data within 30 days. Anonymised usage data (not linked to you) may be retained for operational purposes.

10. Your GDPR Rights (EU Users)

If you are located in the European Union, you have the following rights under GDPR:

To exercise any of these rights, email us at hello@mathonyx.com. We will respond within 30 days.

11. Children

TradingBrief is not intended for users under the age of 18. We do not knowingly collect data from minors. If you believe a minor has created an account, please contact us and we will delete it promptly.

12. Third-Party Services

Beyond Anthropic (briefing generation) and Apple (payments and distribution), TradingBrief does not share your data with third parties. We do not sell, rent, or trade your personal data.

13. Changes to This Policy

If we make material changes to this policy, we will update the "Last updated" date above and, where appropriate, notify you via the app. Continued use of the app after changes constitutes acceptance of the updated policy.
