Model Training Opt-Out Exception

High severity
Share 𝕏 Share in Share

What it is

We may use Materials to provide, maintain, and improve the Services and to develop other products and services, including training our models, unless you opt out of training through your account settings. Even if you opt out, we will use Materials for model training when: (1) you provide Feedback to us regarding any Materials, or (2) your Materials are flagged for safety review to improve our ability to detect harmful content, enforce our policies, or advance our safety research.

Why it matters

The opt-out is not a complete opt-out: two broad exceptions—feedback interactions and safety flags—mean a significant portion of your conversations may still be used for AI training regardless of your stated preference.

Consumer impact

Anthropic's Consumer Terms permit the company to use your conversations, inputs, and outputs to train AI models by default, with a limited opt-out that does not apply when you provide feedback or when your content is flagged for safety review. Subscriptions auto-renew and fees are non-refundable upon cancellation, meaning you could be charged for a full billing period even if you cancel. You can opt out of conversation data being used for model training by navigating to your Claude.ai account settings and disabling the training opt-out toggle.

What you can do

⚠️ These actions may provide transparency or partial mitigation but may not fully address the underlying issue. Effectiveness varies by jurisdiction and individual circumstances.
  • Opt Out of Arbitration
    Log into your Claude.ai account, navigate to account settings, and locate the model training preference toggle. Disable the option to allow your conversations to be used for training. Note this opt-out does not cover feedback interactions or safety-flagged content.

Applicable agencies

  • FTC
    The FTC has authority under Section 5 of the FTC Act over deceptive data practices, including opt-out mechanisms that do not function as disclosed to consumers.
