Privacy FAQs

Slack is committed to providing you with the information and tools you need to meet data and privacy obligations. Below you'll find resources related to our Privacy Policy and specific data protection laws:

Workspace Settings

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

Delete a workspace

A Workspace Primary Owner can delete their workspace. Read more about deleting a workspace and our security practices.

Transfer ownership of a workspace 

The Workspace Primary Owner can transfer ownership of their workspace. 

Message & file retention

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.

Edited and deleted messages

On the Free plan, if you have the option to edit messages, only the most recent version will remain. On paid plans, Workspace Owners or Admins can choose to keep a log of all edited messages. Visit your Workspace Settings to confirm which option your workspace has enabled. 

Data storage

Where is my data stored?

Slack is hosted with Amazon Web Services (AWS) and we are currently using data centers hosted in the United States and Europe. The data center hosting location applicable to each Slack customer can vary if the organization uses our data residency feature. Data residency for Slack allows global teams to choose the region where certain types of data at rest are stored. To learn more, visit Data residency for Slack.

Does the GDPR require EU personal data to stay in the EU?

The GDPR does not require EU data to reside in the European Union. Slack’s Data Processing Agreement and the European Union’s Model Clauses will continue to ensure compliance for EU personal data transfers outside of the EU.

How secure is my data on Slack?

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 exceed the industry standard when it comes to protecting your organization and we've outlined many of our security practices and certifications on our website.

Is my data encrypted?

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

Data exports & ownership

Who owns the data submitted to a workspace?

A Customer owns and controls all content submitted to their workspace. Slack processes customer data on behalf of the Customer.

What export tools are available with Slack and who can use them?

  • All plans
    On any plan, Workspace Owners and Admins can export all data (messages and files) from public channels. 
  • Free and Standard plans
    The option to export data from all channels and conversations is available to workspaces on the Free and Standard plans under limited circumstances. We require Workspace Owners on these plans to provide (a) valid legal process, (b) consent of members, or (c) a requirement or right under applicable laws.
  • Plus plan
    Workspace Owners can request to export data from all channels and conversations, including private channels and direct messages. 
  • Enterprise Grid and select Slack plans
    Org Owners can apply to export content from all channels and conversations, including private channels and direct messages, and from all conversations that a single user is a part of. Discovery APIs also allow eligible Slack customers to use third-party applications to export, retain, or archive messages and files submitted to Slack. This includes messages and files migrated to a Slack Enterprise Grid org.

How do I delete personal information from Slack?

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.
