Apple and Facebook are among NPR's financial supporters.
Starting Monday, iPhone and iPad users will have a simple but powerful new way to control how their data is used.
With Apple's latest software update, iOS 14.5, iPhone and iPad users will now encounter pop-ups in the apps they use, asking whether the user wants to allow the app "to track your activity across other companies' apps and websites." The user can then select whether or not to allow the app to track them and share their data.
That little pop-up could create big trouble for companies that make their money through targeted advertising – including Facebook.
