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.

Senate Democrats demand answers on FBI's Kavanaugh probe

Senate Democrats are demanding that the FBI hand over "all records and communications" related to the FBI tip line set up to investigate Supreme Court Justice Brett Kavanaugh when he was a nominee in 2018.

Why it matters: The ask comes after the FBI revealed it received more than 4,500 tips about Kavanaugh when he was awaiting Senate confirmation amid sexual assault allegations. Only the most "relevant" of these tips were forwarded to the Trump White House.
