Privacy Guide
Slack Privacy for Teams: What Your Boss Can See
Slack is a workplace tool, not a privacy tool. Employers on paid plans can access all messages including DMs, and Slack retains data according to employer-configured policies.

Message Retention and Compliance
Slack retains messages according to workspace settings, which employers control. In regulated industries, all messages may be retained indefinitely for compliance. Deleted messages may persist in exports and backups.
Third-Party App Risks
Slack's app ecosystem means third-party integrations can access messages in channels where they are installed. Each app increases the attack surface and potential for data exposure.
Keeping Conversations Private
Treat Slack as a company-monitored communication tool. For personal conversations, union organizing, or discussions about workplace concerns, use WeTalkin on personal devices instead.
