• Disconnect a channel — its tokens are deleted immediately; scheduled posts for it pause.
• Remove ITPS Social from a network (e.g. Facebook Settings → Business integrations) — the network tells us and we disconnect and purge automatically; you get a confirmation code on the data deletion page.
• Delete the workspace (Settings → Danger zone, owners only) — cancels the subscription, disconnects everything, and purges posts and media within 30 days.

Posts already published stay on the networks — they belong to your Page or profile there.
