Apple's latest privacy move has been characterized as an assault on advertising agencies since users will be directly asked if ads can track them across websites and other apps.
Users will be asked if they mind being tracked by websites and apps (like Facebook) and told (in small print) that, if they agree, the data will be used to deliver personalized ads. So, if you agree, when you search for a bathrobe, you would continue to see ads for bathrobes on Facebook or other websites.
According to Tech Crunch, this will inevitably reduce the amount of data that is collected, which would preserve user privacy. Websites would be able to track activities but not attach those activities to a single person. The update will not block Google Analytics, according to Search Engine Journal.
Right now, ads can track the sites you visit and build a profile on you, even if you don't click on an ad. With the profile, they know what you buy every day and share that information with other sites without your permission.
Now, starting with the iOS update in September 2020, if you use an iPhone, you would have to give permission for tracking.
Android users have been able to see app permissions for years on the Google Play app store, according to Tech Crunch.
