Write the config file

First, you need to tell Klaro about the third-party apps and trackers on your site. To do this you write a simple Javascript config. The easiest way to get started is by looking at our documentation, which contains an annotated config file you can modify. No rocket science involved, promised. If you need further help, don't hesitate to ask our friendly Github community.

window.klaroConfig = {
    privacyPolicy: '/privacy.html',
    apps : [
        {
            name : 'google-analytics',
            default: true,
            title : 'Google Analytics',
            purposes : ['statistics'],
            cookies : [/^ga/i],
            callback : function(consent, app){
              // this is an example callback function...
            },
        },
        // ...
    ],
}

Modify your third-party scripts

To make sure that no tracking scripts and third-party apps are loaded without consent, you need to modify your HTML code a tiny bit: For inline scripts, replace the value of the type attribute with text/plain (this keeps the browser from executing the script) and add a data attribute with the original type, e.g. data-type="application/javascript". Also add a data-name attribute that matches the name of the given app in your config, e.g. data-name="googleAnalytics". More detailed information about this is available in our documentation.

# Inline scripts: 
<script type="text/plain"
        data-type="application/javascript"
        data-name="google-analytics">
//...
</script>

# External scripts and resources (img, link, ...): 
<script type="text/plain"
        data-src="https://analytics.kiprotect.com/matomo.js"
        data-name="matomo">
</script>

Load the config and the script

Finally, include both the config script as well as the Klaro code on your page. You can defer the loading of the scripts if you like, just make sure the config is initialized when Klaro loads. You can have a look at our simple example page to get an idea of how to do this. If you want to host Klaro yourself, you can download it here.

<script defer type="application/javascript"
        src="config.js"></script>
<script defer 
        data-config="klaroConfig"
        type="application/javascript"
        src="https://cdn.kiprotect.com/klaro/latest/klaro.js">
</script>
