CAID, for China Anonymization ID, is currently being tested by the state-backed China Advertising Association. It lets these companies continue to track iPhone users and show them targeted ads without the users' consent. Ticking clock: Chinese companies like ByteDance – the people behind TikTok – are looking for loopholes. Apple will be introducing an update to iOS14 in the next several weeks that will allow users to opt out from being tracked, and preventing apps from tracking users if they do. When the update arrives, users will have the nifty ability to choose which of their apps can access their Apple Identifier for Advertisers (or IDFA). Apple calls this App Tracking Transparency (ATT).
