ConductAtlas Analysis

Why it matters (compliance & governance perspective)

This disclosure establishes the operational architecture of the service and clarifies that backend routing occurs regardless of API key usage, which affects data flow and processing procedures within the system.

Consumer impact (what this means for users)

Users operating under this provision understand that their API requests, even when authenticated with their own API keys, pass through Cursor's backend systems for prompt processing, meaning requests do not bypass the service's infrastructure. This affects the data handling pathway and processing procedures users should expect when using the service.
