No credentials
There is no registration or provisioning endpoint, no token to request, and no protected HTTP API. Agents and users should never send credentials to Project Quantity Lab.
Browser-local actions
Calculating changes only in-memory state. Save writes to this browser’s localStorage. Share creates a URL containing bounded project state. Print invokes the browser’s print dialog. None of these actions create a cloud account.
Machine-readable map
The root llms.txt file provides a concise map of calculators, guides, and trust pages. It is informational and is not an access-control or ranking mechanism.
No invented protocols
The site does not advertise OAuth, MCP, A2A, a remote agent, or a server API because those services do not exist.
