Slack claims it does not train generative AI models on customer data, but this hinges on a narrow definition of “generative.” In practice, Slack does use customer data, including messages, files, and usage behavior, to train global machine learning models for features like search, emoji suggestions, and autocomplete. Your data is included by default unless you manually opt out.

To opt out, a Workspace or Org Owner must email [e-mail] with the subject line “Slack Global model opt-out request” and include the workspace or org URL. The instructions are not prominently linked and are buried several clicks deep behind multiple marketing pages. The Privacy Principles page concedes this use and confirms the opt-out process.
