4. Hosting and data processors
We use a limited set of vetted providers. Each is a data processor under Art. 28 GDPR. Data Processing Agreements (DPAs) and EU Standard Contractual Clauses (SCCs) are in place.
Vercel Inc. (Covina, CA, USA) - application hosting. Serverless functions are locked to Frankfurt (fra1), so personal data is processed in the EU. Static assets via global CDN contain no personal data. DPA: vercel.com/legal/dpa.
Supabase Inc. (Singapore) - database and authentication. Our instance runs in Frankfurt, Germany (eu-central-1). DPA: supabase.com/legal/dpa.
Anthropic, PBC (San Francisco, CA, USA) - AI analysis (Buffett Brain). By contract, queries are not used to train their models.
OpenAI, L.L.C. (San Francisco, CA, USA) - fallback AI. By contract, queries are not used for training.
Resend, Inc. (San Francisco, CA, USA) - transactional and newsletter email delivery. Operates on AWS SES.

Stripe Inc. (USA) and Stripe Payments Europe Ltd. (Dublin, Ireland) - payment processing for all paid subscriptions. PCI DSS Level 1 certified.
Financial Modeling Prep and Massive Market Data - public market data only. No personal data is shared with these providers.

PostHog (EU instance, posthog.com) - product analytics for funnels and session recordings. Activated only if configured. Inputs are masked by default.
Microsoft Clarity (USA, Microsoft Corp.) - heatmaps and session replay. Activated only if configured. PII redacted automatically.
We never sell your personal data and never use it for cross-context behavioural advertising.
5. International data transfers
Most personal data stays in the EU because our database and serverless functions run in Frankfurt, Germany.
A small subset is transferred to US-based processors (Anthropic, OpenAI, Resend, ImprovMX, Microsoft Clarity, Stripe). For these we rely on:
- European Commission's Standard Contractual Clauses (SCCs), signed via each provider's DPA
- The EU-US Data Privacy Framework (DPF) for certified providers
- Data minimisation - we only send what's strictly needed (e.g. ticker + financial metrics for AI, not your name)
6. Cookies (TTDSG § 25)
We use only strictly necessary cookies. Under TTDSG § 25 Abs. 2 Nr. 2 and ePrivacy Directive Art. 5(3), no consent is required for these - so we don't show a cookie banner.
Specifically:
sb-access-token,sb-refresh-token- Supabase authentication, set on login, expire on logouttheme- light/dark preference (local-only, never sent to a server)locale- language preference (local-only)- We do not use advertising, retargeting, cross-site tracking, fingerprinting, or third-party analytics cookies.
