What is tracking prevention, and what does it mean on iPhone and Safari?
Tracking prevention is a browser or phone feature that stops ad companies following you from site to site or app to app, so your visits aren’t tied together and their ads don’t chase you.
On iPhone
Safari’s settings have “Prevent Cross-Site Tracking”, and it’s on by itself. You’ll find it in Settings, then Apps, then Safari.
And in Settings, then Privacy & Security, then Tracking, there’s “Allow Apps to Request to Track”. Turn it off and no app asks you; every app is told not to track you.
In computer browsers
Edge has “Tracking prevention” at three levels, and Firefox has “Enhanced Tracking Protection”.
Chrome has an option that sends sites a “Do Not Track” request, but it’s off by default, and Google itself says most sites, Google included, don’t change anything when they receive it.
In m7bok
It blocks trackers from the moment you open it, keeps each site’s cookies to that site, and lets each site see you as a separate device.
