Initialize the plugin in your MauiProgram class:

public static MauiApp CreateMauiApp()
{
    var builder = MauiApp.CreateBuilder();

    builder
        .UseMauiApp<App>()
        .ConfigureFonts(fonts =>
        {
            fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
            fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
        })
        .UsePrivacyGlass();

    return builder.Build();
}

Using Plugin.Maui.PrivacyGlass

Including the XAML namespace

To use the plugin in XAML, add the following xmlns to your page or view:

xmlns:privacyglass="clr-namespace:Plugin.Maui.PrivacyGlass.Controls;assembly=Plugin.Maui.PrivacyGlass"

Using the PrivacyGlassView

Wrap the content you want to protect inside a PrivacyGlassView:

<privacyglass:PrivacyGlassView>
    <VerticalStackLayout>
        <Label
            HorizontalOptions="Center"
            HorizontalTextAlignment="Center"
            LineBreakMode="WordWrap"
            FontSize="Medium"
            TextColor="Black"
            Text="Very sensitive information!" />
        <Label
            HorizontalOptions="Center"
            HorizontalTextAlignment="Center"
            LineBreakMode="WordWrap"
            FontSize="Large"
            FontAttributes="Bold"
            TextColor="Red"
            Text="DO NOT SHARE!" />
    </VerticalStackLayout>
</privacyglass:PrivacyGlassView>

Note: PrivacyGlassView protection is not enabled by default.

You can use the IsProtected property to toggle protection on or off:

Unprotected content	Content protected
<privacyglass:PrivacyGlassView IsProtected="False">	<privacyglass:PrivacyGlassView IsProtected="True">

---

If you have multiple instances of the PrivacyGlassView on your page and want to toggle all at once, you can inject the IPrivacyGlass interface into your view and call the TogglePrivacyGlass method to toggle protection on or off.

private readonly IPrivacyGlass _privacyGlass;

public MainPage(IPrivacyGlass privacyGlass)
{
    InitializeComponent();

    _privacyGlass = privacyGlass;
}

private void ShowHideAll_Clicked(object? sender, EventArgs e)
{
    MainThread.BeginInvokeOnMainThread(() =>
    {
        _privacyGlass.TogglePrivacyGlass();
    });
}

Multiple unprotected content	Multiple content protected

---

Imagine you want to protect something behind a paywall or keep content secret until a user action. You can also add KeepScreenOn="True" to the PrivacyGlassView to prevent it from being affected by calls to the TogglePrivacyGlass method from IPrivacyGlass:

<Border
    StrokeThickness="2"
    Stroke="Black"
    StrokeShape="RoundRectangle 20"
    Padding="5">
    <Grid>
        <privacyglass:PrivacyGlassView
            IsProtected="True"
            KeepScreenOn="True">
            <!-- Super secret content here... -->
        </privacyglass:PrivacyGlassView>
        <Label
            VerticalOptions="Center"
            HorizontalOptions="Center"
            FontSize="Large"
            Text="Subscribe to unlock!" />
    </Grid>
</Border>
