Slack records which teams, people, and content you interact with

Slack says it collects information about the teams, channels, people, features, content, and links you interact with in the service.

Team posts are private by default, but admins may access them

Your posts require team membership to view by default, but some otherwise-private content may be accessible to admins; eligible owners can export private-group and direct messages.

The policy describes administrator access as applying in some cases. Exporting private-group and direct messages requires an appropriate service level and enabled Compliance Exports.

Messages default to staying for the workspace’s lifetime

By default, channel, private-group, and direct messages remain while the team exists; paid-plan admins can preserve edited or deleted copies for a set period.

Administrators can change retention settings, including reducing retention duration. The option to preserve edited or deleted copies is available once a team moves to a paid Slack version.

Removing an integration leaves its indexed content in Slack

If a connected service has sent content indexed in Slack, removing the integration stops it going forward but does not delete that content; it must be deleted manually.

This applies if you add a service integration and content from it is received and indexed in Slack.

An organization may learn you use Slack through a work email

If your signup email belongs to or is controlled by an organization, Slack may share that address and associated team names with it.

This applies to an email address belonging to or controlled by an organization; the policy distinguishes free webmail addresses such as Gmail, Hotmail, or Yahoo.

If you join a workspace, its Customer owns what you submit

For an invited user, the workspace Customer owns submitted messages and files and can set controls that may affect access, retention, sharing, or deletion.

This applies when you join a Customer-controlled workspace as an Authorized User. The terms say the Customer may be an organization or another person or entity that created the workspace.

A workspace Customer or Slack can end your access

Your access ends if the Customer’s subscription ends or either the Customer or Slack terminates access; Slack also describes when it may disable an account directly.

These provisions apply to Authorized Users in a Customer-controlled workspace. Slack says it may directly intervene if the Customer does not take appropriate action or Slack believes there is a credible risk of harm.

The terms seek to exclude consumer-law protections where allowed

They describe Slack as a workplace tool, not for consumer purposes, and seek to exclude consumer-law protections where permitted, while preserving rights that cannot lawfully be excluded.

The same clause says the terms do not restrict, exclude, or modify consumer rights and remedies that cannot lawfully be excluded.
