Does Claude AI Save Chats? Understanding Anthropic’s Data Policies

You may wonder, does Claude AI save chats, and what does that mean for privacy? Yes, Claude AI saves chats temporarily—up to 90 days for individual users and based on custom retention settings for enterprise users—but conversations are not used for training unless you provide explicit feedback or consent.

This article explains how Claude AI manages your conversations, focusing on data retention, privacy safeguards, and user control, so you know exactly what happens to your information.

Anthropic, the company behind Claude AI, emphasizes privacy, security, and user control in its policies. Below, we break down the specifics of data storage, access, and user options.

Data Retention: How Long Does Claude AI Keep Your Chats?

Anthropic’s data retention policies differ based on whether you are an enterprise customer or an individual user.

For Enterprise Users

• Custom Retention Settings: Organizations can set their own data retention periods, with a minimum of 30 days. By default, data is stored indefinitely unless the company specifies otherwise.

• Immediate Deletion Upon Change: If a company changes its retention policy, any data outside the new window is deleted promptly, typically at midnight UTC on the specified day.

For Individual Users

• 90-Day Storage Window: Individual user chats are stored for up to 90 days before being automatically deleted.

• Training Data Policy: Claude AI does not use your conversations for model training unless you provide explicit feedback (such as a thumbs-up or thumbs-down), flag a conversation, or request support.

Privacy and Security: How Is Your Data Protected?

Anthropic implements several measures to safeguard your information:

• Anonymization: Personal identifiers, such as your name, email, or IP address, are removed from stored conversations to prevent them from being linked back to you.

• Encryption: All data is encrypted both while being transmitted to Anthropic’s servers and while stored, using widely recognized security protocols.

• Restricted Internal Access: Only authorized staff can access chat data, and all access is logged for auditing purposes.

User Control: Managing and Deleting Your Chats

Anthropic provides users with meaningful control over their data:

• Delete Individual Chats: You can remove specific conversations directly within the app.

• Bulk Deletion: Multiple chats can be deleted at once, either through built-in app features or compatible third-party tools.

• Deletion Timeline: When you delete chats, Anthropic removes them from its systems—meaning all storage locations—within 30 days.

Data Use and Model Training: Are Your Chats Used to Improve Claude?

By default, your conversations are not used to train Claude AI:

• No Automatic Training: Chats are excluded from training unless you provide explicit consent.

• Consent-Based Review: Only feedback (thumbs-up/thumbs-down), flagged content, or direct support requests are reviewed by Anthropic.

• Safety Exceptions: If a conversation is flagged for safety reasons, it may be reviewed by a limited number of authorized personnel, but access remains tightly controlled.

Anthropic’s Additional Security Commitments

To reinforce its privacy and security promises, Anthropic also conducts:

• Regular Security Audits: Ongoing evaluations ensure that data protection measures remain effective.

• Role-Based Access Controls: Access to data is limited based on staff roles and responsibilities.

• Transparent Data Management: Users and organizations have clear options for managing and deleting their data.
