LangChain Terms of Service

This Terms of Service governs use of LangChain's commercial platform products, including LangSmith and associated services, and establishes a binding agreement between LangChain, Inc. and users or organizations accessing those services. The agreement states that users grant LangChain a license to process and use content submitted through the services, that LangChain may suspend or terminate accounts for violations of acceptable use policies, and that the terms authorize LangChain to modify pricing, features, and service availability with notice. The document includes a limitation of liability clause capping LangChain's damages exposure, a mutual indemnification provision, and an intellectual property assignment structure covering outputs generated through the platform; these provisions are broadly consistent with B2B SaaS industry norms, though the scope of the content license and output ownership assertions may warrant careful review by enterprise customers. The agreement engages the FTC Act's unfair and deceptive practices framework, CCPA and GDPR data processing obligations given the platform's developer-facing nature and likely international user base, and potentially the EU AI Act given LangChain's AI tooling products; applicability of specific data protection obligations depends on whether LangChain acts as a data processor or controller in a given deployment context.
