Training opt-out

A setting or contract term that prevents a vendor from using your prompts, files, or outputs to train its models.

Definition

Many consumer AI products use interactions for training by default and provide a settings toggle to opt out; business and API plans typically exclude training by default. Terms differ by product and plan, and opt-outs may not cover all data types. Reviewing the policy and enabling opt-out is a basic step for work use.

Why it matters when choosing a tool

If you paste confidential material into AI tools, opting out of training and checking retention are essential.
