What it is

Slack can change what the service does — adding or removing features — and if you keep using Slack after being notified, you are legally agreeing to those changes.

Consumer impact (what this means for users)

Slack can unilaterally modify its services and terms, and simply continuing to use the platform after receiving a notification email counts as your organization's legal agreement to those changes — even if the notification is easy to miss.

Why it matters (compliance & risk perspective)

Organizations that rely on specific Slack features for compliance or operational purposes may find those features changed or removed, and continued use constitutes acceptance of any new terms associated with the changes.

View original clause language
Slack reserves the right to modify the features and functions of the Services, including by adding or removing features, subject to Slack's obligation to provide notice of material changes. Slack will notify Customer of material changes to the Services via email or in-product notification. Continued use of the Services following notice of such changes shall constitute Customer's acceptance of the changes.

Institutional analysis (Compliance & legal intelligence)

REGULATORY FRAMEWORK: Unilateral modification clauses are scrutinized under US contract law (requiring adequate notice to be enforceable), EU Directive 93/13/EEC on unfair contract terms, and UK Consumer Rights Act 2015. Under GDPR Article 28(3), changes to data processing activities may require documented amendment to the DPA. The FTC has issued guidance that material changes to privacy practices require affirmative consent, not just continued use.
