What it is

The agreement addresses how LangChain processes data submitted through the platform, including user content, model inputs and outputs logged through LangSmith, and account information.

This analysis describes what LangChain's agreement states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability and practical outcomes may vary by jurisdiction, enforcement context, and individual circumstances. Read our methodology

ConductAtlas Analysis

Why it matters (compliance & governance perspective)

Developers and businesses using LangSmith's tracing and evaluation features may transmit sensitive data, personal information, or proprietary business logic to LangChain's infrastructure, and the terms governing how that data is processed are material to compliance with GDPR, CCPA, and industry-specific regulations.

Interpretive note: The exact data processing clause text was not available due to document truncation; the specific scope of LangChain's data processing obligations and the availability of a standalone DPA cannot be confirmed from the available document text.

Recent Activity

This document changed recently

Medium May 22, 2026

The updated terms introduce a new deployment architecture option (BYOC) alongside existing Cloud and Hybrid options, giving customers more control over infrastructure placement. LangChain's explicit commitment to not use customer data for large language model training now has clear written language in the Terms, whereas the prior version only referenced 'products' generically. However, the expanded non-warranty clause now states the platform is not warranted to be 'accurate' or 'complete,' which broadens the disclaimers of liability. Customers should review which deployment option aligns with their infrastructure and compliance requirements.

Institutional analysis (Compliance & governance intelligence)

1. REGULATORY LANDSCAPE: Data processing provisions in AI developer platform agreements engage GDPR (particularly Articles 28, 13, and 32 regarding processor obligations, transparency, and security), CCPA Sections 1798.100-1798.199, and HIPAA if protected health information is processed through the platform. The EU AI Act requires evaluation for AI system providers and deployers regarding data governance and logging obligations. LangSmith's automatic tracing functionality, which may capture model inputs and outputs, creates a data minimization consideration under GDPR Article 5. 2. GOVERNANCE EXPOSURE: High for organizations deploying LangSmith in environments that handle personal data. The automatic tracing features of LangSmith may capture personal data embedded in model inputs and outputs without explicit data minimization controls, creating GDPR and CCPA compliance obligations that require proactive configuration by the deploying organization. 3. JURISDICTION FLAGS: EU and UK organizations using LangSmith must confirm that a valid Data Processing Agreement is in place under GDPR Article 28 before transmitting personal data through the platform. California organizations should assess CCPA service provider agreement requirements. Organizations in regulated industries including healthcare and financial services must assess whether personal data categories prohibited from third-party processing are at risk of capture through LangSmith tracing. 4. CONTRACT AND VENDOR IMPLICATIONS: A standalone DPA should be executed before any personal data is processed through the platform. Procurement teams should request LangChain's subprocessor list, data retention schedules, and security certification documentation (such as SOC 2) as part of vendor due diligence. The ToS alone may be insufficient to satisfy GDPR Article 28 processor agreement requirements. 5. COMPLIANCE CONSIDERATIONS: Organizations should implement LangSmith configuration controls to filter or redact personal data from traces before transmission to LangChain's infrastructure. Data mapping exercises should identify all platform features that transmit data externally and confirm that appropriate contractual and technical safeguards are in place. GDPR data protection impact assessments may be required for high-risk AI deployments that use LangSmith for observability.
