Handling sensitive data

In order to protect user privacy, you can configure Smartlook to not record sensitive data.

Currently, there are three methods to handle sensitive data:

• Rendering modes
• Sensitivity
• Masks

Rendering modes

The Smartlook SDK offers three rendering modes to create session recordings. Each rendering mode renders the app screen in a different way. The default rendering mode for the Smartlook SDK is Native (RenderingMode.NATIVE).

📘

When using the Native rendering mode, the SDK can record sensitive data in your application.

The rendering modes available in the Smartlook SDK:

Setting the rendering mode

To set the rendering mode:

Smartlook.setRenderingMode({ renderingMode: RenderingMode.NATIVE });

Reading the rendering mode

To see what rendering mode the SDK is using:

Smartlook.getRenderingMode(successCallback);

function successCallback(renderingMode: RenderingMode) {
	console.log('Rendering mode:' + renderingMode);
}

Hidden elements

👍

Locally hidden elements

Sensitive elements are hidden locally on the device. No sensitive data is transferred to or stored in the dashboard.

🚧

Automatically-detected touch events

Some screens display sensitive data through automatically detected touch events. For more information, see Secure custom keyboard example.

Handling WebView sensitivity

You can change the WebView recording by controlling it's sensitivity:

Smartlook.setWebViewSensitivity({ isSensitive: false });

🚧

WebView recording

By default, WebView recording is enabled. To ensure security, set elements as sensitive.

If WebView is recorded, all sensitive elements on the displayed website should be marked as sensitive so that they are hidden. You can mark sensitive elements as sensitive using HTML elements with .smartlook-hide css class:

<div class='smartlook-hide'>
   This will be hidden.
</div>

🚧

button and submit inputs

By default, all inputs are hidden except for button and submit types.

Shown elements

Hidden inputs that are hidden by default will be recorded if marked with .smartlook-show css class:

<input type="text" class='smartlook-show'>

Recording masks

In cases where areas of the app shouldn't be recorded, but cannot be defined by a .smartlook-hide element, you can use a RecordingMask:

Smartlook.setRecordingMask({ 
    recordingMaskList: [
      { maskType: 'COVERING',
      	maskRect: { left: 0, top: 0, width: 100, height: 250 }
      }, 
      { maskType: 'COVERING', 
       	maskRect: { left: 80, top: 50, width: 100, height: 250 }
      }
    ]
  });

You can only have one Recording mask set at a time, but the recording mask can contain a list of RecordingMaskElement to cover multiple areas at once.

RecordingMaskElement can be one of two types:

RecordingMask example

The following example describes a RecordingMask in action.

On the left:

• The blue box represents a video_item element.
• The red box represents a video_item_image element.

On the right:

• The video_item element (blue box) has a Covering value. The Covering value masks the element in the session recording.
• The video_item_image element (red box) has an Erasing value. The image is visible in the session recording because the Erasing value cancels the Covering value.
