Change Summary
LangChain updated its Terms of Service on May 22, 2026 to clarify deployment options and data protection commitments. The company introduced a new 'Bring Your Own Cloud Deployment' (BYOC) option, redefined 'Hybrid Deployment' to specify that LangChain operates the control plane while customers operate the data plane, and explicitly extended its commitment not to use customer data for training to include 'large language models.' The disclaimer clause was also expanded to state the platform is not warranted to be 'accurate' or 'complete.' These changes affect how customers understand their deployment choices and what data protections apply.
