# Delete custom data

> Permanently remove an uploaded dataset.

Deleting a dataset removes its rows and metadata. Widgets that referenced the dataset no longer resolve their data until you re-wire them to a different source.

<Warning>
  Deletion is permanent — custom data is hard-deleted, with no Archive recovery. Keep a copy of the original file if you might need it later.
</Warning>

<Steps>
  <Step title="Open Manage Custom Data">
    From the **Data Query** widget's **Custom Data** source, click **Manage** next to the **Dataset** label.
  </Step>

  <Step title="Choose Delete">
    Select the dataset and choose **Delete**. Confirm when prompted.
  </Step>
</Steps>

## API

`DELETE /v1/custom-data/{id}` permanently removes the dataset. It returns `404` if the dataset doesn't exist in your account.
