You own the AI-generated content Claude produces for you, but this ownership is conditional on following Anthropic's rules — and Anthropic makes no guarantees that outputs are unique or free from third-party IP claims.
Your conversations with Claude may be used to train Anthropic's AI models by default, though you can opt out in account settings. Subscriptions auto-renew and fees are generally non-refundable, so cancellation timing is critical. You can opt out of AI model training by going to your account settings on Claude.ai.
