Do Not Track

What is “Do Not Track”?

Most web browsers are initially set up to accept cookies. “Do Not Track” is an opt-out preference setting that users can enable to refuse all cookies or indicate when a cookie is being set. In other words, this setting allows users to inform web services which offer content across the Internet that they do not want certain information about their internet activity collected across websites when they have not interacted with that service’s content on the page.

Browser Support

The “Do Not Track” browser setting is supported by recent versions of many browsers, including the following:

    1. Internet Explorer 9+
    2. Safari 5.1+
    3. Firefox 5+
    4. Chrome 17.0 + (via third-party extension)

    What does this mean for StumbleUpon?

    When you turn on “Do Not Track” in your browser, StumbleUpon stops collecting the information that allows us to recommend what’s best for you based on your recent visits to websites that have integrated our badges or widgets.

    We do this by removing the cookies saved to your browser when you visit certain websites linked to StumbleUpon Services. StumbleUpon will still provide you with personalized recommendations based on your Interests and Stumbling history, but without this extra browser information.
