Introducing the Offen Consent Tool

We are building Offen, a fair web analytics software that treats operators and users as equal parties. Operators can gain insights into how users interact with their services, while ensuring that they retain full control over their data.

Along the way, we created the Offen Consent Tool. A lightweight solution for managing user consent on websites. Read the full version of this article on the Offen blog.

The Toolis using 1st Party Cookies to store user's consent decisions. To enable this mechanism, you need to deploy therespectiveserver to a sibling domain, i.e. if you plan to use the tool onwww.example.com,itshould be served on a domain likeconsent.example.com. The tool can serve any number of domains at once, so it's possible to use the same deployment for multiple domains at once.

Next deploy the application to a domain likeconsent.example.com. On the host sitewww.example.com embed the client script:

<script src="https://consent.example.com/client.js">

which exposedwindow.ConsentClient. In your client side code, construct a new client instance pointing at your deployment and request user consent for the desired scope(s):

const client = new window.ConsentClient({ url: 'https://consent.example.com' })client  .acquire('analytics', 'marketing')  .then((decisions) => {    if (decisions.analytics) {    // load analytics data    }    if (decisions.marketing) {    // trigger marketing tools    }  })

The Offen Consent Tool further allows you to create the binary yourself and provides a development setup. It can also be used as a library and be integrated into any web server written in Golang. Learn more
