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 and the default location is AWS US. The data centre hosting location applicable to each Slack customer can vary if an 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.

Please note that the other categories of data, ā€œOther Informationā€, as defined in Slackā€™s Privacy Policy are processed in the US. To support delivery of our Services, Slack may engage Sub-processors. A current list of Sub-processors for the Services, including the identities of those Sub-processors and their country of location, is accessible via https://www.slack.com/slack-subprocessors

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. Slackā€™s Data Processing Addenda and the European Unionā€™s Model Clauses (Standard Contractual Clauses) will continue to ensure compliance for EU personal data transfers outside of the EU. Our Data Processing Addenda are available to all customers regardless of the Slack plan they are using.

While Slack remains self-certified under the E.U.-U.S. Privacy Shield and the Swiss-U.S. Privacy Shield, we are currently relying on Standard Contractual Clauses for compliance with the transfer of personal data.

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?

How do I delete personal information from Slack?

When youā€™re ready to permanently leave a workspace, you can deactivate your account and ask a Workspace Primary Owner to remove your profile information. (A Workspace Primary Owner can contact Slack on your behalf to complete this.) Slack will only delete member profile information at the request of a Primary Owner. If thatā€™s you, and youā€™ve been asked to delete a memberā€™s profile you can reach out to us at feedback@slack.com.

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.
