Apps must include a link to their privacy policy in the App Store Connect metadata field and within the app in an easily accessible manner. The privacy policy must clearly and explicitly: Identify what data, if any, the app/service collects, how it collects that data, and all uses of that data.
Privacy nutrition labels give consumers standardized, comparable information about data collection before they install an app, enabling more informed consent decisions — a significant consumer protection measure absent from most other app distribution platforms.
Apple's App Review Guidelines directly affect what apps consumers can access, what data those apps may collect, and how they can pay for digital content — Apple's mandatory in-app purchase requirement means app developers cannot offer cheaper prices through external payment links on iOS. Consumers benefit from Apple's content and privacy review standards, which prohibit apps from collecting data beyond declared purposes and require age-gating for adult content, but have no direct appeal mechanism if Apple removes an app they rely upon. You can review an app's declared data practices by checking the App Privacy section on any App Store listing before downloading.
