Customer Data Ownership and Slack Usage Rights

Medium severity
Share 𝕏 Share in Share 🔒 PDF

What it is

Your organization owns the data you put into Slack, but you are granting Slack a broad license to access, copy, and use that data to run and improve its services.

Consumer impact (what this means for users)

While Customer Data ownership remains with the organization, the broad license granted to Slack to copy, distribute, and process that data — including for service improvement — means employees' messages and files are accessible to Slack for a wide range of operational purposes.

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.
  • Export Your Data
    Workspace administrators can export Customer Data by navigating to the workspace admin panel and selecting the data export option. Enterprise Grid customers can use the Slack Discovery API for more comprehensive exports.

Why it matters (compliance & risk perspective)

The license granted to Slack is broad and includes the right to copy and distribute Customer Data, which has implications for data sovereignty, confidentiality, and compliance with regulations that restrict where and how data can be processed.

View original clause language
As between Slack and Customer, Customer retains all right, title and interest in and to the Customer Data. Subject to the terms of this Agreement, Customer grants Slack a worldwide, limited-term license to access, use, process, copy, distribute, perform, export and display Customer Data, only as necessary to provide, maintain, and improve the Services, or as otherwise permitted by this Agreement or by Customer.

Institutional analysis (Compliance & legal intelligence)

REGULATORY FRAMEWORK: This provision engages GDPR Article 28 (processor obligations and the requirement for written data processing instructions), Article 46 (international transfer mechanisms where data is copied to Slack's global infrastructure), and CCPA §1798.140(ag) (service provider use restrictions). The scope of 'improve the Services' as a permitted use purpose requires careful scrutiny against GDPR's purpose limitation principle (Art. 5(1)(b)).
