You also are able to delete individual conversations, which will be removed immediately from your conversation history and automatically deleted from our back-end within 30 days.
Knowing that deleted conversations take up to 30 days to be fully removed from Anthropic's systems is important for users who share sensitive personal information with Claude and want it erased promptly.
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.
