Data sources
Legal and service notice.
Public sample
The public service uses a project-authored synthetic fixture named SYNTH. The values were not copied or sampled from a market.
The service does not call Yahoo, Alpha Vantage, OPRA, an exchange, or a broker.
User-supplied snapshots
A user can send a snapshot for private, short-lived analysis. The service does not add it to the public sample, aggregate it, sell it, or redistribute it.
The hosted policy blocks Yahoo, yfinance, and personal Alpha Vantage data. A user's confirmation cannot override a provider contract.
Future licensed data
A current-data provider must grant the required display, derived-output, storage, redistribution, commercial, and AI or MCP delivery rights in writing.
Licensed mode cannot start until a reviewed licence identifier is approved in the source code. An environment variable alone cannot approve a provider.
