You must be at least 18 years old or the minimum age required to consent to use the Services in your location, whichever is higher.
The 18+ minimum age requirement is higher than the COPPA threshold of 13, which means Anthropic has chosen a more protective approach to age gating, but also means teenagers who circumvent the age requirement are violating the Terms and may have their accounts terminated.
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.
