Share 𝕏 Share in Share 🔒 PDF

What it is

Slack can use your organization's messages, files, and other workspace data to train and improve its artificial intelligence features, unless your workspace administrator turns off this option.

Consumer impact (what this means for users)

This provision means that messages and files you send in Slack — including sensitive business communications and personal information — may be processed for AI model training, creating privacy and confidentiality risks for both employees and the organizations they work for.

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 in as a workspace administrator, navigate to Settings & Administration, then Workspace Settings, and locate the AI data usage or machine learning opt-out option to disable AI training use of your workspace data.

Why it matters (compliance & risk perspective)

Confidential business communications, personal employee data, and sensitive files shared in Slack workspaces could be used by Slack to train AI models unless the organization takes affirmative steps to opt out.

View original clause language

Slack may use Customer Data to train and improve AI/ML models and features that are part of the Services. Customers may opt out of this use by configuring their workspace settings or by contacting Slack. Where Customer has opted out, Slack will not use Customer Data to train its global AI/ML models.

Institutional analysis (Compliance & legal intelligence)

REGULATORY FRAMEWORK: This provision implicates GDPR Article 6 (lawful basis for processing), Article 22 (automated decision-making), and Article 28 (processor obligations) — the EU lead supervisory authority is the Irish DPC. It also engages CCPA/CPRA Cal. Civ. Code §1798.140(ag) regarding service provider restrictions on secondary use of personal information, and the emerging EU AI Act (Regulation 2024/1689) Articles 10 and 53 regarding training data governance for general-purpose AI models. The FTC Act Section 5 is engaged where data use exceeds consumer reasonable expectations.
