What it is

We and our service providers use cookies, scripts, or similar technologies ('Cookies') to manage the Services and to collect information about you and your use of the Services. These technologies help us to recognize you, customize or personalize your experience, market additional products or services to you, and analyze the use of our Services to make them safer and more useful to you.

Why it matters

Marketing and behavioral tracking cookies extend data collection beyond your Claude conversations to include browsing patterns and cross-site activity, which may be shared with advertising partners.

Consumer impact

Anthropic collects your conversation content (prompts and AI responses), device identifiers, browsing behavior, and any personal data you include in messages to Claude, and may use this data to train its AI models. Users who opt out of model training should be aware that conversations flagged for safety or policy review can still be used for training without their consent, representing a meaningful limitation on the opt-out right. You can opt out of having your conversations used for model training by navigating to your Claude.ai account settings, or submit a data deletion request by emailing privacy@anthropic.com.

Applicable agencies

  • FTC
    Behavioral advertising tracking without adequate opt-out mechanisms may constitute an unfair or deceptive practice under FTC Act Section 5, particularly given FTC guidance on online tracking.
