Slack Terms of Service

This document is Slack's Main Services Agreement (MSA), governing the relationship between Slack Technologies LLC (or its affiliates) and the customer entity that subscribes to Slack's services, established on a B2B contractual basis where the customer organization bears primary legal responsibility for its authorized users' conduct. The agreement states that customers grant Slack a worldwide, non-exclusive license to use, reproduce, modify, and distribute customer data solely to provide and improve the services, while Slack asserts ownership of all service-related intellectual property and reserves the right to modify, suspend, or discontinue services with or without notice under certain conditions. Notably, the agreement positions the contracting party as the organizational customer rather than individual end users, meaning individual employees (authorized users) are governed through their employer's acceptance of these terms rather than any direct consumer relationship; the limitation of liability clause caps Slack's aggregate liability at amounts paid in the prior 12 months, and mutual indemnification obligations are structured in ways that place significant compliance responsibility on the customer organization. The agreement engages GDPR and related EU/EEA data protection frameworks through its Data Processing Addendum by reference, CCPA obligations for California-based customers, and standard commercial contract frameworks under California law; enforcement dependencies are jurisdiction-specific and organizations operating in regulated industries such as healthcare or financial services may face additional compliance obligations that the MSA alone does not resolve. Enterprise procurement teams should evaluate whether supplemental data processing agreements, BAAs, or sector-specific addenda are required before deployment.
