I would like to input sensitive data into my chats with Claude. Who can view my conversations?

Updated this week

This article is about our consumer products (e.g. Claude Free, Pro, Max (and when using Claude Code with those accounts)).

How We Protect Your Data When You Help Improve Claude

When you allow us to use your chats or coding sessions to help improve Claude, we implement several layers of protection for your privacy.

Privacy Protections We Provide

  • We automatically de-link your data from your user ID (like your email address) before any review.

  • Access is limited to a small number of personnel involved in model training.

  • We will use tools and processes derived from our work on privacy-preserving analysis tools to filter or obfuscate sensitive data. In addition to that, our pioneering research in post-training techniques helps to minimize the amount of personal data included in Claude’s outputs.

  • Your data is used solely to make Claude better for everyone - we do not use such personal data to contact people, build profiles about them, to try to sell or market anything to them, or to sell the information itself to any third party.

  • You maintain full control and can adjust your privacy settings at any time.

Please note: If our safety classifiers flag your conversations, they may still be used to improve our internal trust and safety models, detect harmful content, enforce our policies, or advance our safety research.

Being Mindful About Sensitive Information

While we have these protections in place, we also recommend being thoughtful about sharing highly sensitive personal details such as:

  • Financial information (SSN, credit card numbers, bank account details)

  • Health records or medical information

  • Passwords or private login credentials

  • Confidential business or personal documents

Your Control Over Privacy Settings

You can adjust your privacy and model improvement settings at any time by following the steps here. Learn more about your privacy settings and controls here.
