If you do not want a unique DART cookie from DoubleClick, there is a simple procedure to follow. Click here to replace your unique DART cookie with an opt-out DART cookie.

If you select a DART opt-out cookie, ads delivered to your browser on behalf of clients using DoubleClick’s ad-serving technology will be targeted based only on the non-personally-identifiable information that is automatically transmitted in the Internet environment when an ad request is received by our ad servers, and your DART cookie will not be uniquely identified. The non-personally identifiable information that is automatically transmitted includes your browser type, Internet service provider, information about the general content of the site or page displayed on your browser and other non-personally identifiable information provided by the site.

What happens if I choose to opt-out?
The system will assign you a cookie with the following “value” : id=OPT_OUTinstead of a cookie that contains a unique string of characters, e.g. id=8000002cd6f0880

When you receive this cookie, DoubleClick's systems will know that you have opted out and will not attempt to assign other DART cookies in the future. Since the DoubleClick opt-out cookie does not contain a unique user number, it does not allow your browser to be identified uniquely.

PLEASE NOTE that if you erase or otherwise alter your browser's cookie file (including upgrading certain browsers) you may need to opt out again.

PLEASE NOTE that opting out of the ad-serving cookie does not mean that you will stop seeing either pop up advertising or banner ads embedded in websites! You can control many pop ups by using free software available on the Internet or by disabling JavaScript on your browser. DoubleClick has no control over the use or frequency of pop-up ads employed by website publishers or software manufacturers. For more information about pop-up ads, please click here.
