Apple’s big privacy update came out a year ago. What did it do for you?

When Apple rolled out its long-awaited, much-hyped privacy update one year ago this week, it was accompanied by an ad that attempted to visualize what the new feature did. In it, there’s a man going about his day, and every time he interacts with a business, an employee latches on and starts following him everywhere he goes, collecting and broadcasting the man’s personal information. A prompt shows up on the man’s iPhone, giving him the option to “Ask App Not to Track.” He taps it, and all of his unwelcome guests pop like balloons, disappearing into clouds of dust.
