Apple’s 14.5 operating system update in 2021 gave you a major new security feature: App-Tracking Transparency. This essentially lets you block the system advertising identifier (IDFA) that feeds your personal user data back to advertisers on the app. Apple has made sure you can opt into this feature while protecting other identifiers like your email address, as well as not punishing you for locking apps out. TikTok – one of the deepest data-grabbing apps on the market – is a prime candidate for transparency. Head to Settings > Privacy > Tracking to set up an alert whenever TikTok requests user data. You can do the same thing on your Apple TV.
