In a system enabling a user to control tracking of online activities of the user on a user device, a list of trackers is presented to the user. For each tracker, an option to opt out of or opt in into tracking by that tracker is also presented. The user's preference for a particular tracker, i.e., opt out or opt in, is transmitted to the tracker via a message that includes the specific ID or IDs used by that particular tracker. |
