WHAT THE TECH? Apple’s latest iOS update provides users with option to avoid being tracked by apps – WRCBtv.com

Many free apps such as Facebook and Instagram earn revenue by tracking what users do on their phones. The data includes websites they visit, games they play, and things they search for. That data is then made available to advertisers who want to reach potential customers. So when a business or ad agency buys ads on Facebook, they can target users by age, gender, location, interests and other information gathered from the data.
