# Uninstallation

> Completely remove Chainstack Self-Hosted from your Kubernetes cluster using cpctl, including cleanup of persistent volumes and namespace resources.

<Warning>
  Uninstallation permanently deletes all data including deployed nodes, configuration, and user data. This cannot be undone. Use `--keep-pvcs` if you want to preserve blockchain node data.
</Warning>

## Basic uninstall

```bash theme={"system"}
cpctl uninstall
```

This removes the Helm release and deletes all associated PersistentVolumeClaims. You will be prompted to confirm before anything is deleted.

## Preserve data

To remove the Control Panel but keep the blockchain node data on disk:

```bash theme={"system"}
cpctl uninstall --keep-pvcs
```

This is useful if you plan to reinstall and reattach the existing volumes.

## Preview before deleting

To see what would be deleted without actually deleting anything:

```bash theme={"system"}
cpctl uninstall --dry-run
```
