What is the Sovereign Stack?

The Sovereign Stack is a financial software architecture where sensitive banking data (Transactions, Holdings) is fetched via API but analyzed entirely on the client-side (Browser/Local), ensuring the platform provider never sees the user's Net Worth.

Privacy isn't a policy; it's code.

The Sovereign Stack is built on a Local-First foundation. We utilize a deterministic adapter floor to standardize messy broker CSVs at the edge. This ensures 99.9% ingestion accuracy before data ever touches the cloud, reducing server-side compute overhead by 80%.

How the Sovereign Stack works

Traditional Stack (Cloud-First)

  1. User uploads portfolio data → Server
  2. Server stores data in database
  3. Server calculates analytics
  4. Server returns results

❌ Platform sees your Net Worth. Data is stored on vendor servers.

Sovereign Stack (Client-First)

  1. User stores data in Google Drive (their own storage)
  2. Browser fetches data via API (read-only)
  3. Browser calculates analytics locally
  4. Results never leave the browser

✅ Platform never sees your Net Worth. Data stays in your Google Drive.

Key Takeaways

  • Client-side analysis = true privacy. If the math happens in your browser, we can't see it.
  • Your data, your storage. Google Drive is your database, not ours.
  • No vendor lock-in. Export your JSON files anytime. Own your data completely.
  • Privacy by architecture, not policy. Code enforces privacy, not promises.
