4. Information Sharing and Sub-Processors
4.1 Named Sub-Processors (GDPR Article 28)
We engage the following processors to operate the Service. Each is bound by a Data Processing Agreement and processes personal data only on our documented instructions:
- Neon Database (Neon, Inc.) — PostgreSQL hosting, EU region (Frankfurt). Stores account data, portfolios, watchlists, journal entries.
- Railway (Railway Corp., US) — Application hosting and serverless runtime.
- Stripe (Stripe Payments Europe, Ltd., Ireland) — Payment processing. We do not store credit card data on our servers; Stripe processes payments under PCI-DSS.
- Anthropic (Anthropic, PBC, US) — Claude AI model for analytical commentary (deep analysis, portfolio advisor, earnings summaries). Anonymized prompt context only; we do not transmit identifying personal data.
- OpenAI (OpenAI, LLC, US) — Backup AI provider. Same anonymization policy as Anthropic.
- Resend (Resend, Inc., US) — Transactional email delivery (account verification, alerts, payment receipts).
- Alpha Vantage, Financial Modeling Prep (FMP), Finnhub — Market data providers. No personal data shared; only public stock symbols are requested.
- Google (Google LLC, US) — OAuth sign-in (optional). Only when the user explicitly chooses "Sign in with Google".
4.2 International Data Transfers (Schrems II)
Some of our sub-processors (Anthropic, OpenAI, Resend, Railway, Google) are based in the United States. Transfers of personal data to these processors are protected by:
- EU-U.S. Data Privacy Framework (DPF) certification where available, OR
- Standard Contractual Clauses (SCCs) as adopted by the European Commission (Commission Implementing Decision 2021/914), with additional supplementary measures as required by Schrems II (Case C-311/18).
Primary application data (accounts, portfolios) is stored exclusively in the EU (Frankfurt) with Neon Database. US-based processors only receive transient task-specific data (e.g., an anonymized prompt for AI commentary, an email address for delivery).
4.3 Other Disclosures
- Legal Compliance: When required by law (court order, regulatory request) or to protect our rights and the safety of others.
- Business Transfers: In connection with a merger, acquisition, or sale of assets, with notice to affected users.
We DO NOT sell your personal information to third parties. We DO NOT use your data to train AI models.
5. Data Security
We implement appropriate technical and organizational measures to protect your personal information, including:
- Encryption of data in transit and at rest
- Secure password hashing
- Regular security audits
- Access controls and authentication
However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
6. Data Retention
We retain your personal information for as long as your account is active or as needed to provide the Service. You may request deletion of your account at any time by contacting us.
We may retain certain information for legitimate business purposes or as required by law, even after you close your account.
