LangChain Privacy Policy

This document explains how LangChain handles your personal information — including what it collects, who it may share it with, and how long it keeps it. LangChain may share your information with law enforcement or others based on its own good-faith judgment, and may transfer it to another company in a merger or acquisition. If you keep using LangChain's services after the policy changes, you are treated as having agreed to the new terms.

LangChain's Privacy Policy establishes the conditions under which LangChain collects, uses, retains, shares, and transfers users' personal information in connection with its Services. Key limitations include a good-faith-belief standard governing disclosures to law enforcement and private parties, retention tied to three broad purposes with no fixed time limit, and a scope exclusion that removes from this Policy any personal information LangChain processes on behalf of customers as a service provider. Users in the UK and EEA are afforded a legal-basis requirement for any collection or processing, while all processing occurs in the United States. The Policy may be modified at any time, with material changes communicated solely through a date update and reposting on the Services, and continued use constitutes acceptance.

Your personal information may be collected not only through your direct use of LangChain's Services but also from third-party marketing partners, public sources, and data providers, and may be tracked through invisible pixels in emails. LangChain will not deny you access to its services or provide degraded service because you exercised a privacy right, though it may be unable to fully honor a privacy request where legal obligations or service necessity require retaining your data. If you are in the UK or EEA, LangChain is required to have a legal basis before collecting or processing your personal information. Users who do not wish to be bound by a revised Privacy Policy should stop using the Services before the revised policy takes effect, as continued use is treated as acceptance.
