# Live data for launch

Remove the starter rows and test records that you don't want to keep from your app's live data, and learn what the builder account (You) is.

Before people use your app, remove unwanted starter rows and test records from your app's [live data](https://docs.flutterflow.io/ffx/glossary#backend-and-data).

## What's in live data {#whats-in-live-data}

Your live data can hold rows that you added while you built and tried your app, as well as real ones.

Your app's share links, test builds, and **Overview** preview all use live data. Adding, editing, or deleting data in the **Overview** preview changes your live data directly.

Starter rows can also reach your live data when you push a thread. See [How data moves](https://docs.flutterflow.io/ffx/data-copies#how-data-moves).

## Delete test data {#delete-rows}

No single button clears all starter rows from your live data. Owners and developers can delete unwanted rows one at a time from their tables under **Backend › Data**. Tables don't mark which rows came from starter data. You can compare a table against **Backend › Starter data** (which lists what new threads start with), though the two lists can differ: some starter rows never reach live data, tables ignore starter rows added after the first ones arrive, and rows edited or deleted in live data no longer match.

To delete a record from your live data:

1. Open **Backend**, select the table under **Data**, and open **Records**.
2. Open the record that you want to remove.
3. Click **Delete** followed by the kind of record, such as **Delete task**.
4. Click **Delete** to confirm.

To keep the record after all, click **Undo** in the notification before it closes and before you leave the table.

## The builder account {#builder-account}

The builder account, shown as **You**, is a test account for building your app. The preview on **Overview** can sign in to your app as the builder account, so you see your app as yourself.

When starter rows owned by the builder account (**You**) reach your live data, FlutterFlow adds the builder account to your live data too. That account stays even if you delete those rows, cannot be deleted, and never appears in **People**. If your app uses roles and defines an `admin` role, the builder account receives `admin` in live data unless it already has another role.

In **Backend › Data**, a field that links to the builder account shows **You**.

A thread's own data can also hold the builder account. A thread's **Data › Accounts** lists it as **You**, and its account form differs from other accounts' forms:

- You can't change its **Email**, because you sign in to the preview with it.
- It has no **Password** field.
- You can't delete it.

## Troubleshooting {#if-something-goes-wrong}

If a deletion fails or a table won't load, see [Troubleshoot data and sign-in](https://docs.flutterflow.io/ffx/troubleshoot-data).
