Your workspace converts to the Free plan at the end of your billing period.
Free plan limits: 90 days of message history visible, 10 integrations max, 1:1 voice and video calls only.
Older messages beyond 90 days are hidden but not deleted — they return if you upgrade again.
Channels, members, and shared files remain in the workspace.
Slack retains your full message history indefinitely on Pro/Business+ plans. On the Free plan, messages older than 90 days are hidden but stored on Slack's servers. Files attached to hidden messages remain accessible via direct links. Workspace owners can export full history via Workspace Settings > Import/Export Data.
Messages aren't deleted — they become hidden after 90 days on the Free plan. They reappear in their original threads if you upgrade again. You can also export the full history as JSON via Workspace Settings before downgrading.
Workspace owners can delete the entire workspace via Workspace Settings > Settings & Permissions > Delete Workspace. This is permanent — all messages, files, and channels are removed after a 30-day grace period.
On the per-user pricing model, you can deactivate individual accounts — they stop counting toward billing immediately. You can also move users to single-channel guest status (free) for limited access.
Pro ($7.25/user/mo) adds unlimited message history, unlimited integrations, group voice/video, and screen sharing. Business+ ($12.50/user/mo) adds SSO, compliance exports, 99.99% uptime SLA, and 24/7 support. For most teams under 50, Pro is sufficient.
