# Automatic data collection

By default, the Batch SDK will automatically collect some data related to the user's device:

<table><thead><tr><th width="164.21875">Native data</th><th>Description</th><th width="224.3515625" align="right">Default collection status</th><th width="160.890625" data-type="checkbox">Installation based data model</th><th data-type="checkbox">Profile based data model</th></tr></thead><tbody><tr><td>Device Model</td><td>The user's device model information</td><td align="right">false</td><td>true</td><td>false</td></tr><tr><td>Installation ID</td><td>The installation identifier</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Session ID</td><td>The user's session identifier</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>Custom User ID</td><td>The user's custom identifier</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>API Level</td><td>The Batch SDK api level</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Messaging API Level</td><td>The Batch SDK Messaging api level</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Device Language</td><td>The user's device language</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Device Region</td><td>The user's device region</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Device Timezone</td><td>The user's device timezone</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>OS Version</td><td>The user's device iOS version</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>App Version (String)</td><td>The application version (string)</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>App Version (Build Number)</td><td>The application version (number)</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>Bundle Name</td><td>The application bundle identifier</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>Device Date</td><td>The current device date</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>Device Installation Date</td><td>The Batch installation date</td><td align="right">true</td><td>true</td><td>true</td></tr><tr><td>Bridge Version</td><td>Version of the batch bridge (for cross-platform plugin only)</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>Plugin Version</td><td>Version of the batch plugin (for cross-platform plugin only)</td><td align="right">true</td><td>true</td><td>false</td></tr><tr><td>GeoIP</td><td>Whether Batch should resolve the user's location from ip address.</td><td align="right">false</td><td>true</td><td>false</td></tr></tbody></table>

Some of this data are disabled by default and can be toggled on/off according to the user consent:

* Device model
* Device brand
* GeoIP

Use the following API to fine-tune what you want to enable:

{% tabs %}
{% tab title="Kotlin" %}

```kotlin
Batch.updateAutomaticDataCollection {
  it.apply {
    setGeoIPEnabled(true) // Enable GeoIP resolution on server side
    setDeviceBrandEnabled(true) // Enable automatic collection of the device brand information
    setDeviceModelEnabled(true) // Enable automatic collection of the device model information
  }
}
```

{% endtab %}

{% tab title="Java" %}

```java
Batch.updateAutomaticDataCollection(config -> {
    config.setGeoIPEnabled(true) // Enable GeoIP resolution on server side
          .setDeviceBrandEnabled(true) // Enable automatic collection of the device brand information
          .setDeviceModelEnabled(true); // Enable automatic collection of the device model information
});
```

{% endtab %}
{% endtabs %}

{% hint style="info" %}
This API can be used at any time in your application lifecycle and Batch will remember these values, even if your Application reboots.
{% endhint %}
