Anthropic's consumer policy trains on chats by default with a settings opt-out, names a 30-day backend deletion window for individual conversations, and gives no retention period beyond "as long as reasonably necessary".

What Claude's privacy policy and terms of service say about your data

Training on by default

Inputs and Outputs are used to train and improve Anthropic models unless you opt out in account settings, and safety-flagged or reported conversations are still used even after opting out.

No retention period

The policy commits only to retaining personal data "for as long as reasonably necessary" and names no number, though individual conversations are deleted from the backend within 30 days.

Strong rights plumbing

Access, deletion, correction, portability and objection are each spelled out, with privacy@anthropic.com as the request channel and a named Data Protection Officer at dpo@anthropic.com.

Security stated only in adjectives

Security is described as "appropriate technical and organizational security measures" with no named control such as encryption in transit or at rest, and there is no breach-notification commitment.

What the policy is silent or vague on

Not stated: whether training use differs by plan
Not stated: shorter retention for AI conversation logs
Not stated: breach notification
Only partial: keeping user inputs out of model training
