Apple on Monday announced new changes, additions and updates to its App Store Guideline policies, one of which includes developer instructions for implementing App Tracking Transparency. Detailed in a post to Apple's developer portal, the updates are in large part clarifications and modifications to existing rules governing payments, disclosures and app terminology. One noted addition to Apple's ruleset covers App Tracking Transparency, a new iOS feature designed to give users more control over data privacy. Initially slated to debut in 2020, the upcoming feature opts users out of ad tracking by default. When opening an app for the first time, users will see a permission dialogue box with two selections: "Allow Tracking" and "Ask Apps Not to Track."
