A feature on your iPhone or iPad called “App Tracking Transparency” allows you to ask apps not to track you across the internet for advertising and data brokering purposes. Here’s how to use it.
To get the most out of their advertising budgets, advertisers want their ads to be seen by customers who will buy the product or service they are offering. That way, they don’t spend money advertising to the wrong audience. To increase the effectiveness of ads, companies build advertising profiles on individuals, and these profiles can follow you across services run by different companies on the internet.
