Do Not Track - Cookies Problem


I enabled the “Do Not Track” option in my PIWIK analytics platform for my website, and I realized that it works correct on Piwik Analytics because the users that choose DNT, I can’t see any data about their visit. But for any reason the Piwik “cookies” are installed anyway in their browsers although I can’t see the data in the Piwik Analytics Platform.

How can I prevent that Piwik cookies were installed in the visitors browsers although they check the “Do Not Track” option?

Thanks for your help.

Hi there,
Which cookie are created on your browser with DoNotTrack? Maybe you could create an issue in our tracker: Issues · piwik/piwik · GitHub - thanks


I am seeing the same thing as reported by hzmartin. DEspite the enabling of DNT the cookies _pk_id and _pk_ses are still here, and their content is still sent as a parameter of the HTTP response.
