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 plus their contact info
  • Your workspace’s subscription
  • Message and file retention policies
  • Available data export options

 💡 Read more about the Workspace settings page

Delete your Slack account

If you’re ready to permanently leave a workspace, members can deactivate their account and ask a workspace owner to delete their profile information

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 and 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 subscriptions, workspace owners can customise 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 subscription, if you have the option to edit messages, only the most recent version will remain. On paid subscriptions, workspace owners or admins can choose to keep a log of all edited messages. Go to 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 centres hosted in the United States and Europe. The data centre hosting location applicable to each Slack customer can vary if the organisation uses our data residency feature. Data residency for Slack allows global teams to choose the region where certain types of at-rest data 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 Privacy Shield certification, data processing agreement and the European Union’s standard contractual clauses (also known as 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’re proud to surpass the industry standard when it comes to protecting your organisation 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 and 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 subscriptions
    On any subscription, workspace owners and admins can export all data (messages and files) from public channels. 
  • Plus subscription
    Workspace owners can request access to a tool that will download all content from public and private channels. 
  • Free and Standard subscriptions
    The option to download all workspace data is available to workspaces on the Free and Standard subscriptions in limited circumstances. We require workspace owners on these subscriptions to demonstrate (a) valid legal process, (b) consent of members or (c) a requirement or right under applicable laws.
  • Enterprise Grid and selected Slack subscriptions
    Discovery APIs 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.

💡 See our Guide to Slack import and export tools to learn more. 

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 have this done.) 

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.
