What it is

Anthropic can change its Terms of Service at any time, and simply continuing to use Claude after the changes counts as your agreement to them — even if you didn't read the update.

This analysis describes what Anthropic'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

Institutional analysis (Compliance & governance intelligence)

(1) REGULATORY FRAMEWORK: Unilateral modification clauses in consumer contracts are scrutinized under GDPR Art. 7 (consent must be as easy to withdraw as to give; unilateral changes to data processing terms may require re-consent), the EU Unfair Contract Terms Directive (93/13/EEC, implemented in national law), the UK CRA 2015 (Consumer Rights Act, which renders unfair terms in consumer contracts unenforceable), and the FTC Act Section 5. California consumer protection law (CLRA) also restricts modification of material terms without adequate notice and consent. (2)
