PRIVACY REQUEST FORM

Frequently asked questions

A Customer owns and controls all content submitted to their workspace. Slack processes customer data on behalf of the Customer. See our Privacy Policy, Customer Terms of Service and our User Terms of Service for more.

The Primary Owner has ultimate decision-making capabilities, and represents the Customer in administering the workspace. As with all enterprise software, Slack is a tool for business and employers are responsible for setting standards for behavior and are in the best position to enforce those standards. There are some Privacy related functions that can only be performed by the Primary Owner. For example, only the Workspace Primary Owner can transfer ownership of their workspace. If you’re not sure who the Primary Owner is, visit the About This Workspace page to find out.

The Workspace Settings page is where members can review info about workspaces they've joined. Here's what you'll find there:

  • Your Workspace Owners and Admins and their contact info
  • Your workspace's plan
  • Message and file retention policies
  • Available data export options
💡 Read more about the Workspace Settings page.

When you're ready to permanently leave a workspace, you can deactivate your account and ask a Workspace Owner to remove your profile information. (A Workspace Owner can contact Slack on your behalf to complete this.) Before you deactivate your account, you can also remove any profile information you'd like, such as your name and email address. Depending on your workspace's settings, you may be able to delete messages and files you've shared. Get in touch with a Workspace Owner or Admin if you have any questions about editing and deletion settings.

For any workspace, the default message and file retention setting is to keep everything for as long as the workspace exists. On paid plans, workspace owners can customize their retention policies. They can choose to set a custom time frame to keep messages and files, and they can also choose to retain all versions of an edited or deleted message.

Slack is committed to ensuring our infrastructure is secure, redundant, and reliable, while providing your team with tools to administer your environment. We are proud to meet industry standards when it comes to protecting your organization and we"ve outlined many of our security practices and certifications on our website.

Slack provides data encryption in transit and at rest. Read more about our approach to security.

When it comes to transferring data, we offer standard contractual clauses through our Data Processing Addendum (DPA). Our Data Processing Addendum supplements the Customer Terms of Service or any MSA and is available to all of our customers on free or paid plans.

While we do not rely on the EU-U.S. Privacy Shield and the Swiss-U.S. Privacy Shield for the transfer of personal data, we do self-certify to both programs. Additionally, our privacy practices comply with the Asia-Pacific Economic Cooperation (“APEC”) Cross Border Privacy Rules (“CBPR”) system and the Privacy Recognition for Processors (“PRP”). More information about the APEC framework can be found here.

You can read more in our blog post: A note to our customers on international data transfers.

We adhere to the General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA) and other applicable global regulations. Read up on Slack’s commitments and review our latest certifications on our Compliance Page.
