Guideline 5.1.2 – Legal – Privacy – Data Use and Sharing

We continued to find that your app privacy information you provided in App Store Connect indicates you collect data in order to track the user, including Crash Data. However, you do not use App Tracking Transparency to request the user’s permission before tracking their activity.

Starting with iOS 14.5, apps on the App Store need to receive the user’s permission through the AppTrackingTransparency framework before collecting data used to track them. This requirement protects the privacy of App Store users.

Next Steps

Here are two ways to resolve this issue:

– If you do not currently track, or decide to stop tracking, update your app privacy information in App Store Connect. You must have the Account Holder or Admin role to update app privacy information.

– If you track users, you must implement App Tracking Transparency and request permission before collecting data used to track. When you resubmit, indicate in the Review Notes where the permission request is located.

Resources

– Tracking is linking data collected from your app with third-party data for advertising purposes, or sharing the collected data with a data broker. Learn more about tracking.
– See Frequently Asked Questions about the new requirements for apps that track users.
– Learn more about designing appropriate permission requests.

Please see attached screenshot for details.

簡単にいうと、ユーザーをトラッキングしたり、広告をつけるなら、Appにトラッキングしていいかのアラートを表示させろということです。

AdMobで広告をつけているアプリだと、この対応は必要になってきます。この対応をしないとそのユーザー好みの広告が表示されなくなります。ちなみにですが、好みの広告を表示させると、1.3倍くらい収益が上がるそうです。

ただこれを表示するだけで、一応このリジェクトはクリアできます。

対応方法

先ほどのアラートを表示させる対応です。

今回は、SwiftUI、Storyboardそれぞれで対応方法を記載していきたいと思います。AppDelegateを使った実装でも良いのですが、今回はより簡単な実装方法を紹介します。

Storyboard

import AppTrackingTransparency

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
    })
}

SwiftUI

続いてSwiftUIのやり方も紹介します。それほどやり方は変わりません。

import AppTrackingTransparency

.onReceive(NotificationCenter.default.publisher(for: UIApplication.didBecomeActiveNotification)) { _ in
    ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in })
}
