Respect Browser Do Not Track Setting


Jonathan Mayer and Arvind Narayanan are the two principal researchers at Stanford University who have been working on the Do Not Track (DNT) technology that uses information in the HTTP header to universally opt out of all online tracking.

Convert supports DNT

Convert supports Do Not Track because we think it’s really important that you have a simple way to control how end-user information gets used. We honor DNT as a signal for how you and your end-users want us to use data.

The technical implementation on how Convert Experiences will support this field can be explained with DNT’s three possible values:

  1. Do Not Track (Opt out of tracking)
  2. Track (Opt into tracking)
  3. Null – No preference

By default, web browsers use the null value (no preference), indicating that the end-user hasn’t expressed a desire of whether they want to be tracked or not. From February 23rd 2018, Convert Experiences will not load the scripts/experiments when option one, the Do Not Track (Opt out of tracking) in the browser is set and will load with the other two options.
