This article will teach you how to use it.
How to enable the App Activity Recording feature
I want to turn on the iPhone “Record app activityFunction, you have to firstUpgrade to iOS 15, iPadOS 15 as the new version to use, It will not be enabled automatically by default, and it will only be recorded if it needs to be enabled manually.Record app activitySteps for activating features:
Step 1. Go to iOS.Configuration“choose”Privacy“, slide down and click”Record app activity」。
Step 2. A set “Record app activity“The feature is enabled to start recording.
When opening “Record app activityAfter “, Apple said that the iOS / iPadOS systemIt will start recording APP application activity data, resources and network access records for the past 7 days, And stored on the user’s device, there are six common types of behavior known:

How can I open and analyze the app activity record?
After opening all frequently used apps once, the analysis can normally be opened after more than three days.App activity record“File, orYou have recently installed a specific app. If you suspect or are concerned about privacy and security, you can ask and analyze it using the following methods。
1. Install App Privacy Insights tool
Temporarily unable to read due to built-in system “Record app activityFile, you can directly use the “Privacy Insights-App Privacy Insights” tool to read and analyze.Record app activity“Log file tool.
Seeing that this app was launched by a Chinese developer, some people started asking again. Is not your use of this app the same as sending analytics data to China?
In principle, I would recommend that apps be shared after confirmation. First, look at the app’s privacy information in the “Privacy Insights App Privacy Insights”, which indicates that no information will be collected.
Next I use this tool for log analysis. I use 0. Internet activities are very common. However, all Internet activity is associated with the domain “ssl.mzatatic.com”. Then who is this server again?
After querying domains with whois, I found that this domain is owned by Apple (click me to view). In addition, Apple also uses the list of Apple product pages on the corporate network. It also lists the domains used by the App Store and also contains “* .mzstatic .com”, the main purpose of this domain is actually the image cache server provided by Apple to the thumbnails of the App Store, and it is also a server used to retrieve App Icons.
From the above, it can be confirmed that the tool “Privacy Insights-App Privacy Insights” will not steal any of your information.
2. Import the included App Activity files into the system
After installing the APP, you can use iOS directly “system」>「Privacy」>「Record app activity“Click”Save App Activity“, the tool to open the log file will appear, select” from the listImport to privacy insights」。
Click on the import page .ndjson import report directly from the top corner “Import“In the app and click”Fisy“To complete the import. (Each time you want to analyze, you must import through this step)
Query App Activity Record
「Privacy Insights – App Privacy Insights“Analysis -sark silAll records for APP application activity are presented in a visual list, You can go further for the APP you want to know aboutRequest all access times, connection server or system access times, Everything can be clearly seen.
Note: If you find that the APP icon goes blank, you need to close the APP from the background once and reopen it.
For example, if you want to check if YouTube has secretly read albums and videos in the background, search for or turn on the microphone, just click on YouTube to view “Access log“You can know all the access behaviors. If you find that you did not open the app today, but start reading photos and stop accessing photos, then it is possible that the app secretly reads your data in the background, what means there is a problem.
Also in “Internet activity“Share, it will also record The domain and server to which the app is connected, and even record the number of connections in detail, If it is still automatically connected to the background when it is not enabled, it is necessary to determine which server you need to connect to and whether there is frequent network activity.
This feature is just like the built-in firewall blocker recorder in iOS 15 / iPadOS 15 system, which can record all APP connection records of the iPhone device.
What is an abnormality?
This time added iOS 15 “Record app activity“Function can make the most of the app’s death. Users can check access rights for app at any time to ensure that their privacy is not violated. Then, under what circumstances can it be determined that the app has misread?
The easiest way, as long as the “Access log“In the query read APP records, if you do not open a particular app all day,It has been found that the app will often read photos as other system functions in the background, which means that the app has abnormal reading behavior。
Currently, some netizens have discovered the well-known Chinese app “WeChat, Taobao, QQ“, from time to time the photos in the user’s device are secretly read in the background. This behavior will also make people suspicious. Most of the time the photos and video data in the device are secretly read in the background, which will also cause the device to consume more power. (If you find that other apps have secretly enabled system features, you are also welcome to provide them.)
There is not only a problem with the Chinese APP, but also an unknown reading behavior along with LINE. Even if you do not open the photo album (transfer photos) or use it, it will continue to read and find the photos in This behavior does not appear Normally the official LINE is asked for further explanation.
update: LINE official comment “We are currently investigating the issue you are consulting」。
It’s even more exaggerated along with the most popular Xiaopi shopping app, just browseContinue to read photos, contact information and location in the background automatically, It seems very simple to have you only the smooth shrimp. In fact, this APP will go through the photos of the device, locate and get contact information in the background, causing the iPhone device to consume more power.
