+# Removing an app
+
+<PaidPlanBanner />
+
+All good things must come to an end. You can `uninstall` your app if you need to remove an app from a workspace, change app permissions, or `delete` the app in its entirety.
+
+## Uninstall an app from your team {#uninstall-app}
+
+Removing an app from a workspace doesn't have to be a permanent decision. Sometimes uninstalling the app to remove it's active presence in channels is sufficient! This option has the added benefit of reinstallation at a later time without recreating the entire app.
+
+To uninstall an app using the CLI, use the `slack uninstall` command. Then, choose the workspace you want to remove the app from:
+
+```bash
+slack uninstall -a A123ABC456 -t T123ABC456
+```
+
+```bash
+⚠️ Warning
+   App (A123ABC456) will be uninstalled from my-workspace (T123ABC456)
+   All triggers, workflows, and functions will be deleted
+   Datastore records will be persisted
+
+❓ Are you sure you want to uninstall? Yes
+
+🏠 Workspace uninstall
+   Uninstalled the app "my-app" from workspace "my-workspace"
+```
+
+## Delete an app from your team {#delete-app}
+
+:::danger[Deleting your app _permanently_ deletes all of its data]
+
+Your app's related workflows, functions, and datastores will also be deleted. This decision is final and cannot be undone.
+
+:::
+
+To delete an app using the CLI, use the `slack delete` command:
+
+```bash
+slack delete -a A123ABC456 -t T123ABC456
+```
+
+```bash
+⚠️ Danger zone
+   App (A123ABC456) will be permanently deleted
+   All triggers, workflows, and functions will be deleted
+   All datastores for this app will be deleted
+   Once you delete this app, there is no going back
+
+❓ Are you sure you want to delete the app? Yes
