Acceptable use policy

Last updated: 1st February 2024

This acceptable use policy sets out a list of acceptable and unacceptable conduct for our Services. If we believe that a violation of the policy is deliberate, repeated or presents a credible risk of harm to other users, our customers, the Services or any third parties, we may suspend or terminate your access. This policy may change as Slack grows and evolves, so please check back regularly for updates and changes. Capitalised terms used below but not defined in this policy have the meaning set forth in the User Terms of Service.

Slack may exercise its right to analyse information to protect the safety of users and prevent illegal activity. We use privacy-protective hash-based detection software to proactively remove child sexual abuse material. Slack also accepts and investigates reports of violations of both the User Terms of Service and Acceptable Use Policy from Customers and Users. Reports are reviewed by trained individuals and prohibited content may be deleted from the Services. We place strict controls over employee access to Customer Data. There are technical controls and audit policies in place to ensure that access to Customer Data is logged. For more information see our Security practices page.
