"If you are a California resident, you may have additional privacy rights under the California Consumer Privacy Act (CCPA). These rights include the right to know about the personal information collected about you and the purposes for which it is used and shared, the right to delete personal information we have collected from you (with some exceptions), the right to opt out of selling or sharing personal information, the right to correct inaccurate personal information, the right to limit use and disclosure of sensitive personal information, and the right to not be discriminated against for exercising your rights. To submit a rights request, please visit our Privacy Request page. You can opt out of the sale or sharing of your personal information by clicking the 'Do Not Sell or Share My Personal Information' link in the footer of our website.— Excerpt from Slack's Slack Privacy Policy
REGULATORY LANDSCAPE: This provision directly implements CCPA as amended by CPRA, enforced by the California Privacy Protection Agency (CPPA) and the California Attorney General. The opt-out right for 'sharing' covers cross-context behavioral advertising even without monetary exchange, reflecting the CPRA expansion of the original CCPA 'sale' definition. Failure to honor opt-out requests or to provide a functional opt-out mechanism creates enforcement exposure under California law. GOVERNANCE EXPOSURE: Medium. The provision discloses the opt-out mechanism but the functional adequacy of the mechanism (whether it effectively stops all covered sharing, including with Salesforce for advertising purposes) requires operational verification. Compliance teams should confirm that the opt-out signal propagates to all downstream data recipients, including Salesforce affiliates and third-party ad platforms. JURISDICTION FLAGS: This provision applies specifically to California residents and is grounded in CCPA/CPRA. Other U.S. states with comprehensive privacy laws (Virginia, Colorado, Connecticut, Texas, and others) may extend similar rights to residents of those states even if not explicitly addressed in this policy version. Organizations with employees or customers across these states should assess whether Slack's opt-out mechanism satisfies multi-state obligations. CONTRACT AND VENDOR IMPLICATIONS: Enterprise customers acting as controllers of Customer Data should assess whether they have independent CCPA opt-out obligations to their California employees using Slack, distinct from Slack's own consumer-facing opt-out. Service provider agreements between enterprise customers and Slack should prohibit Slack from using Customer Data for its own advertising purposes. COMPLIANCE CONSIDERATIONS: Compliance teams should verify that the 'Do Not Sell or Share' opt-out link is present and functional on all relevant Slack web properties, that opt-out signals are honored within the 15-day CPRA timeframe, and that opt-out elections are not overridden by re-consent flows or account updates. Annual CCPA training and data inventory updates should reflect Slack as a data recipient.
