Beginning with iOS 14.5, due out in the next couple of weeks, iPhone apps will have to ask users for permission to track their digital activity.

Why it matters: Only if a user gives permission will apps have access to the unique advertising identifier assigned to each device. Apple will also take action against apps that try to fingerprint individual devices via other methods.

  • Apple first announced the plan last June, but delayed making it mandatory until now to give the industry more time to prepare.
  • Apple is continuing to prepare customers, app makers and the ad industry about the change. Today it is making changes to a cartoon it uses to illustrate a hypothetical example of how apps can track people's activity, including sharing information with data brokers.
  • Facebook and others remain opposed to what Apple is doing, but are preparing their apps to comply with the rules.

Between the lines: One place you won't see the ad-tracking permission prompt is within Apple's own apps. The rules do apply to Apple, but the company said none of its apps, including those with ads, use such tracking.

The White House on Thursday evening nominated Rick Spinrad, an oceanographer at Oregon State University, to head the National Oceanic and Atmospheric Administration (NOAA).

Why it matters: Filling the NOAA slot would complete the Biden administration's leadership on the climate and environment team. The agency, located within the Commerce Department, houses the National Weather Service and conducts much of the nation's climate science research.

Israeli Prime Minister Benjamin Netanyahu has instructed the delegation traveling to Washington, D.C. next week for strategic talks on Iran to stress their objection to a U.S. return to the 2015 nuclear deal and to refuse to discuss its contents, Israeli officials say.

Why it matters: That position is similar to the one Israel took in the year before the 2015 nuclear deal was announced, which led to a rift between the Israeli government and the Obama administration. History could now repeat itself.
