+title: "Managing your organization"
+description: "Leave or delete your Lightdash organization from the Danger zone in General settings."
+---
+
+The **Danger zone** at the bottom of **Settings → General** is where you can either leave the organization (any member) or delete it entirely (admins only). Both actions are irreversible.
+
+## Leaving an organization
+
+Any member of an organization can leave it from their own settings — they don't need an admin to remove them.
+
+### How to leave
+
+1. Go to **Settings → General**.
+2. In the **Danger zone** card at the bottom, click **Leave '<your organization>'**.
+3. Type the name of the organization into the confirmation field to confirm.
+4. Click **Leave**.
+
+You cannot leave an organization if you are the only admin. Before you can leave, you must promote another member to admin so that the organization still has at least one administrator.
+
+## Deleting an organization
+
+Deleting an organization removes the entire workspace and **all of its content, including every user, project, chart, dashboard, and space**. This is irreversible and there is no recovery path — make sure this is what you want.
+
+### Who can delete an organization
+
+Only users with **organization admin** access see the Delete option in the Danger zone.
+
+### How to delete
+
+1. Go to **Settings → General**.
+2. In the **Danger zone** card, click **Delete '<your organization>'**.
+3. Type the name of the organization into the confirmation field to confirm.
+4. Click **Delete**.
+
+The organization, all its users, and all of its content are removed.
+
+<Warning>
+  **There is no undo.** Once an organization is deleted it cannot be restored. Before deleting, consider whether leaving the organization or transferring admin to another user would serve your purpose.
+</Warning>
