# Data Bank

> Store and manage structured data for your applications

Data Bank provides structured data storage that your [BRICKS](https://bricks.tools) applications can read and write at runtime. Manage your data from [BRICKS Controller](/controller).

## Overview

Data Bank stores key-value data that your applications access at runtime. Use it for:

* Application configuration that changes without redeploying
* User-generated content and form submissions
* Shared state across multiple devices running the same application
* Dynamic content that updates in real time

## Managing data

In BRICKS Controller, navigate to **Data Bank** to view and manage your data:

* **Browse** stored data entries
* **Create** new data entries
* **Edit** existing values
* **Delete** entries you no longer need

## Data sync

Data Bank syncs data between the server and devices in real time. When you update a value in BRICKS Controller, devices running the application receive the update automatically.

## Sandbox mode

You can enable sandbox mode on individual devices in [BRICKS Foundation advanced settings](/foundation/settings) to isolate Data Bank data. In sandbox mode:

* Data changes on the device are not synced to the server
* The device uses a local copy of the data
* Other devices are not affected

This is useful for testing data-driven features without impacting production data.
