## Components

| Component        | Where it runs                   | Required                 |
| ---------------- | ------------------------------- | ------------------------ |
| Flutter app      | Your Android device             | Yes                      |
| Supabase         | Supabase cloud (or self-hosted) | Yes                      |
| FastAPI backend  | VPS, EC2, Railway, Fly.io       | Yes                      |
| Embedding server | Same server as FastAPI          | Optional (for AI memory) |

***

## Minimum requirements

**FastAPI backend:**

* 1 vCPU, 512 MB RAM (t3.micro or equivalent)
* Python 3.11+
* Open port 8000 (or behind nginx on 443)

**Embedding server (optional):**

* 2 vCPU, 2 GB RAM recommended
* The BAAI model loads \~180 MB into memory
* Docker installed

***

## Data privacy

All your financial data lives in **your own Supabase project**. Vantage never sends transaction data to any third-party analytics service. The only external API calls are:

* Anthropic API (your question + relevant context, no raw transactions)
* Yahoo Finance / CoinGecko (ticker symbols only, no personal data)
