Ensure Prevent Cross-site Tracking in Safari Is Enabled

LowLevel 1Automatedmacos

Description

There is a vast network of groups that collect, use, and sell user data. One method used to collect user data is pay and provide content and services for website owners. Along with that "assistance," the site owners also push tracking cookies on visitors. In many cases the help allows a content owner to keep the site up. The tracking cookies allow information brokers to track web users across visited sites. For better privacy and to provide some resistance to data brokers, prevent cross-tracking. Cross-tracking allows data-brokers to follow you across the Internet to enable their business model of selling personal data. Users should protect their data and not volunteer it to marketing companies.
