We may modify these Terms at any time. If we make material changes to our Terms, we will notify you via email or a notice within the Services at least 30 days before the effective date of the changes. By continuing to use our Services after the new Terms become effective, you agree to be bound by the revised Terms.
Continued use of the service after a change constitutes acceptance, meaning you could be bound by materially worse terms—such as expanded data use or new arbitration conditions—simply by not cancelling in time.
Anthropic's Consumer Terms permit the company to use your conversations, inputs, and outputs to train AI models by default, with a limited opt-out that does not apply when you provide feedback or when your content is flagged for safety review. Subscriptions auto-renew and fees are non-refundable upon cancellation, meaning you could be charged for a full billing period even if you cancel. You can opt out of conversation data being used for model training by navigating to your Claude.ai account settings and disabling the training opt-out toggle.
