ConductAtlas Analysis

Why it matters (compliance & governance perspective)

Even if you opt out of training, two significant categories of your content — rated conversations and safety-flagged content — are permanently available for Anthropic's training, which limits the effectiveness of the opt-out.

Consumer impact (what this means for users)

Your conversations with Claude are used by default to train Anthropic's AI models, and even if you opt out, clicking thumbs up or down on any response or having a message flagged for safety review means that content can still be used for training. US users are bound by mandatory arbitration and cannot participate in class action lawsuits against Anthropic, significantly limiting legal remedies. You can opt out of conversation training by navigating to your account settings on Claude.ai.
