Careful
Anthropic's consumer privacy center says chats and coding sessions on Free, Pro, and Max are used to improve models if you allow it, if a safety classifier flags them, or if you otherwise opt in. Incognito chats are excluded. The consumer privacy policy also says inputs and outputs may be used to train models unless you opt out. Those two wordings do not settle the default for a brand-new account, so treat a personal Claude login as Careful for business data until you have checked the privacy setting yourself.

Data-safety checklist
Trains on your data by default
Unknown
The privacy center says Anthropic will use consumer chats and coding sessions to improve models if you choose to allow it. The privacy policy says Anthropic may use inputs and outputs to train models unless you opt out, and that safety-flagged conversations may still be used. We did not find a single sentence that says the setting ships on or off.How to opt out
Steps
On claude.ai, open Settings, then Privacy, and turn off Help improve our AI models. Turning it off stops future training use of new and previously stored chats, but data already in a training run or a finished model stays there. Incognito chats are not used to improve Claude. Thumbs feedback can be stored for up to 5 years.Data retention
What they keep
Deleting a chat removes it from history immediately and from back-end storage within 30 days. If you allow model improvement, Anthropic may keep de-identified data for up to 5 years. Safety-flagged inputs and outputs can be kept up to 2 years, and classification scores up to 7 years.BAA / HIPAA
