# iOS SDK: Environment data

> Filter or disable the environment data attached to tickets with the Gleap iOS SDK. Follow the integration code examples.

Gleap automatically attaches environment data, such as the device model, the iOS version and the battery level, to every ticket and conversation. Your team sees it in the **Env data** tab of a ticket in the dashboard.

You can leave out individual fields or turn off environment data entirely. Both settings can be changed at any time, before or after initializing the SDK, and apply to the next ticket.

<Info>
  Available from SDK v18.1.0.
</Info>

## Ignore individual fields

Pass the keys of the fields you want to leave out. They are removed before a ticket or conversation leaves the device. Keys must match exactly and are case-sensitive. See [Collected fields](#collected-fields) for all keys.

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    Gleap.setEnvDataPropsToIgnore(["deviceName", "batteryLevel"])
    ```
  </Tab>

  <Tab title="Objective-C">
    ```objectivec theme={null}
    [Gleap setEnvDataPropsToIgnore: @[@"deviceName", @"batteryLevel"]];
    ```
  </Tab>
</Tabs>

Each call replaces the previous list. Pass an empty array to send all fields again.

## Disable environment data

Stop collecting environment data altogether. The SDK then gathers no environment data, and tickets arrive with an empty **Env data** tab. Pass `false` (`NO` in Objective-C) to turn it back on.

<Tabs>
  <Tab title="Swift">
    ```swift theme={null}
    Gleap.setDisableEnvData(true)
    ```
  </Tab>

  <Tab title="Objective-C">
    ```objectivec theme={null}
    [Gleap setDisableEnvData: YES];
    ```
  </Tab>
</Tabs>

## Collected fields

The iOS SDK collects the following fields:

`deviceName`, `deviceModel`, `deviceIdentifier`, `bundleID`, `systemName`, `systemVersion`, `buildVersionNumber`, `releaseVersionNumber`, `sessionDuration`, `lastScreenName`, `preferredUserLocale`, `sdkType`, `sdkVersion`, `buildMode`, `batteryLevel`, `phoneChargingStatus`, `batterySaveMode`, `totalDiskSpace`, `totalFreeDiskSpace`, `devicePixelRatio`, `screenWidth`, `screenHeight`

## Exclude environment data per form

The **Exclude data** → **Env data** switch of a form in the [Gleap dashboard](https://app.gleap.ai) keeps working in addition to these methods. It removes the environment data from every ticket submitted through that form.
