Questions people ask about LangChain

Where is LangChain's sub-processor list?

LangChain publishes the list of its own sub-processors at https://trust.langchain.com/subprocessors. We last opened that link on 8 October 2026.

Which legal entity does LangChain contract through?

LangChain Inc., registered in United States. That is the name to put in a record of processing or a sub-processor list, not the brand.

Where is LangChain's trust center?

LangChain publishes it at https://trust.langchain.com/. A trust center, trust page or security page is the same thing under different names: the vendor's own account of how it protects data, and the place it keeps its certifications. It is LangChain's page, so we link to it rather than repeat what it says.
