Apple to roll out new ‘privacy notification’ in early spring

Apple Inc said on Thursday that new privacy pop-up notifications will start appearing on most iPhones as soon as “early spring,” a requirement that major digital advertising firms such as Facebook Inc have warned will harm their businesses.

The one-time notices will require an app developer to ask a user’s permission before the app tracks their activities “across other companies’ apps and websites.” Digital advertising experts believe that the warning will cause many users to decline permission.

Apple announced the move last June but said in September that it would delay the change to give digital advertisers more time to adjust.
