At WWDC 2023, Apple introduced privacy manifests, signatures for SDKs, and required reason APIs. In early 2024, Apple mandated a privacy manifest for every new or updated app and third-party SDK in the App Store.
Privacy manifests are crucial for third-party SDK and app developers to convey privacy practices, including data categories like Contact Information, Health and Fitness. Manifests also state purposes like App Functionality, Analytics, and Third-party Advertising.
