User experience is a relevant variable when collecting consent. We highly encourage you to take advantage of our customization features, in order to provide a branded and user friendly banner to your users.

Remote Customization

Use our Remote Customization options, for a quick out-of-the-box branding that covers all the basics.


In the Appearance section of our Admin Interface, you will find the Layout and Styling tabs:

Under Display Options, you will find the following options:

  • Hide "Deny All" button
  • Hide Language switch

Showing the Language Switch

The language switch will only be shown in the Second Layer, and both of the following requirements need to be fulfilled:

  • Multiple visible languages are added in the Configuration section of the Admin Interface.
  • The "Hide language switch" option is disabled in the Appearance section of the Admin Interface, under the "Layout" tab.

Colors: Set individual colors by providing a specific HEX or using our color picker for the following banner elements:

  • Background Color
  • Text Color
  • Links Color
  • Tab Color
  • Accent Color
  • Button Colors
  • Tabs Color
  • Toggle Colors


Text Font and Size: Only supported via Programmatic Customization.

Logo: Set an image to appear at the top of your banner by providing a URL, as well as it's position:


Supported URL Image Formats

When passing a URL to fetch an image, the SDK supports: iOS: PNG and JPEG. Android: PNG, JPEG, BMP, GIF and WebP.

Supporting SVG Images

As SVG is not a format supported by mobile operating systems, we have provided an ad-hoc solution that requires the addition of dedicaded SVG libraries to your project.

Add SVG kit via Cocoapods:

pod 'SVGKit'

Add Pixplicity to your build.gradle:

implementation ''

Once added, the Usercentrics SDK will make use of it when an SVG needs to be rendered.

Admin Interface

Any changes to the properties available here, will only take effect with a new init of the SDK and clean/updated cache.

Forcing configuration updates during Testing

You may force a configuration update by using the reset() function, or by deleting the app and installing it again. We only recommend doing this when integrating and testing the SDK.

Configuration updates in Production

The SDK caches essential data on device after the first successful init, in order to be efficient with resources and provide offline capabilities. This cache is kept for several days, depending on app usage. Which means user's will not get "Published" changes from the Admin Interface immediately, but we can guaranty changes will take effect for 100% of your user base latest within a week.

Programmatic Customization

Use our Programmatic Customization API, to create advance banner designs and run-time variants. Using this API unlocks features like A/B Testing & Dark Mode.

Compliance Note

Because the Programmatic API enables many customization options, it is important that your DPO (Data Protection Officer) reviews and approves the compliance of your design:


  • A user should always have clear options to accept, deny or save granular choices available as call to actions in the 1st or 2nd layer.
  • The First Layer should always allow a path to the Second Layer.
  • Calls to action should be equally prominent.

Programmatic Customization

When creating the UsercentricsUI banner, a BannerSettings property will be available for you to customize any element of the banner.

BannerSettings is an optional field for UsercentricsBanner constructor and an optional argument for the showFirstLayer and showSecondLayer methods

let bannerSettings = BannerSettings(generalStyleSettings: <GeneralStyleSettings?>,
                                    firstLayerSettings: <FirstLayerStyleSettings?>,
                                    secondLayerSettings: <SecondLayerStyleSettings?>)

let banner = UsercentricsBanner(bannerSettings: bannerSettings)
val bannerSettings = BannerSettings(
    generalStyleSettings = <GeneralStyleSettings?>,
    firstLayerSettings = <FirstLayerStyleSettings?>,
    secondLayerSettings = <SecondLayerStyleSettings?>,

val banner = UsercentricsBanner(context, bannerSettings)
final bannerSettings = BannerSettings(
    general: <GeneralStyleSettings?>,
    firstLayer: <FirstLayerStyleSettings?>,
    secondLayer: <SecondLayerStyleSettings?>,

// First Layer
final response = await Usercentrics.showFirstLayer(
    settings: bannerSettings,

// Second Layer
final response = await Usercentrics.showSecondLayer(
    settings: bannerSettings,
const bannerSettings: BannerSettings = {
    firstLayerSettings: <FirstLayerStyleSettings?>,
    secondLayerSettings: <SecondLayerStyleSettings?>,
    generalStyleSettings: <GeneralStyleSettings?>

// First Layer
const response = await Usercentrics.showFirstLayer(bannerSettings);

// Second Layer
const response = await Usercentrics.showSecondLayer(bannerSettings);
Dark Mode

Use the customization API to define both light and dark designs and use depending on device theme.

let lightBannerTheme = BannerSettings(...) // define light theme
let darkBannerTheme = BannerSettings(...) // define dark theme

let theme = (<Device Theme Dark?>) = darkBannerTheme : lightBannerTheme
let banner = UsercentricsBanner(theme)
banner.showFirstLayer(hostView: self) { }
