How to delete your Slack account
Slack is a workplace messaging platform owned by Salesforce since 2021. Slack accounts are unusual: your IDENTITY is per-workspace, meaning you have a separate Slack account in every workspace you've ever joined. There's also an overarching Slack ID that ties your email across workspaces. Slack stores your messages, files, channels, DMs, and (for Workspace admins) the full audit log. Deleting a personal Slack identity affects ONLY that workspace's account — the workspace owner controls the data.
Delete your Slack account, step by step
- 1To leave a SINGLE workspace: open the workspace, click your avatar > 'View account' > 'Settings' > 'Deactivate account'
- 2The workspace ADMIN must then permanently delete your data from the workspace (per their data-retention policy)
- 3To delete your underlying Slack identity across all workspaces: go to slack.com/account/profile > scroll to 'Close account'
- 4Or email feedback@slack.com requesting closure of your Slack identity
- 5Slack admins of each workspace retain control over message history per workspace policy
What actually happens when you delete
Gets removed
- ✓Your username, profile, avatar, and status in the workspace(s) you deactivate
- ✓Active sessions on every device
- ✓Your member listing in the workspace's people directory
- ✓DM threads from your side of the conversation
- ✓If you delete the Slack ID: cross-workspace identity and sign-in
Stays behind
- ✗Messages you sent in channels stay (workspace owns the content)
- ✗DMs you sent persist in the other person's inbox
- ✗Files you uploaded remain in the workspace's storage
- ✗Audit logs for trust & safety and admin review
- ✗Slack Connect messages in OTHER workspaces are owned by those orgs
Before you delete
Slack's data model means your messages belong to the WORKSPACE, not to you — the workspace admin (your employer, community, etc.) chooses whether to delete messages after you leave. Leaving a workspace removes you from member lists but messages persist by default. To force erasure, file a GDPR/CCPA right-to-delete with the workspace administrator and with Slack as the data processor. Slack Connect / Shared channels carry your messages into OTHER workspaces too — those persist with the recipient orgs.
Download your data from Slack first
Most platforms only honor a data-export request while the account is still active. Do this before you delete.
- 1Slack workspace admins have the export feature (Workspace settings > Import/Export)
- 2As a regular user, you can request a copy of YOUR personal data via slack.com/account > 'Privacy choices' > 'Right to access'
- 3EU/UK users can demand a structured export under GDPR
- 4Slack responds within 30 days with downloadable archives
Want to take a break instead? Deactivate
Deactivation hides your profile without permanently destroying it. Logging back in restores everything.
- 1In each workspace, open profile menu > 'Deactivate account'
- 2Your access is removed but the workspace admin still controls historic messages
- 3To stop emails entirely: Settings > 'Notifications' > disable all
If deletion fails — or you live in the EU, UK, or California
You have a legal right to request erasure of your personal data under GDPR (EU/UK) and CCPA (California). Use these official channels if the self-service flow doesn't work.
Slack deletion FAQs
Why are my messages still in Slack after I leave a workspace?+
Slack messages legally belong to the workspace owner, not to you. When you deactivate, you're removed as a member but the messages remain unless the workspace admin actively deletes them. To force erasure, file a GDPR/CCPA request with both Slack AND the workspace administrator (typically your employer or the community organizer).
How do I delete my Slack account entirely, across every workspace?+
There's no one-click 'nuke everything' button. Deactivate yourself in each workspace, then go to slack.com/account/profile and close your Slack ID. For complete erasure of message content, you also need each workspace admin to comply with a deletion request — which is voluntary unless legally compelled.
What's the difference between deactivating and deleting Slack?+
Deactivation removes you as an active member of a workspace; your historical messages stay. Deletion of your Slack ID removes the underlying identity across workspaces (sign-in stops working) but the messages still belong to each workspace. There is no single 'delete my data everywhere' button on Slack alone.
Will my employer be notified when I deactivate my Slack?+
Workspace admins typically get a notification or can see in audit logs that an account deactivated. If your employer manages the workspace, they will know — coordinate with HR/IT before deactivating from a work-required Slack.
Can I delete just my Slack DMs without leaving the workspace?+
Yes for messages you sent — open the message, hover, click '...' > 'Delete message'. Slack admins can disable user-level message deletion via workspace settings; if you can't delete, ask the admin to enable the permission or file a deletion request with them.
What about Slack Connect / shared channels?+
Messages you send in Slack Connect channels are visible to (and stored by) the other organization too. Your leaving doesn't retract them — you have to request deletion from each connected workspace separately.
