How to cancel Slack
To deactivate your Slack account:
- Sign in to the appropriate team and visit here
- Scroll down to the Deactivate account section
- Click Deactivate my account
- On the confirmation page, click Yes, deactivate my account. This change will take effect immediately
Note: Deactivating your account does not remove messages or files you’ve posted. If you’d like to delete content, be sure to do so before you deactivate your account. If you want to return to this Slack team in the future, a Team Administrator will need to re-enable your account.
