What are the iPhone's "activity tracking" and "tracking permission"?How to check and change the settings

Recently, when I was operating the iPhone, a pop -up, "Do you allow you to track your activities across other companies' apps and websites?"The options are "Request to avoid tracking to the app] and [permit].

In the first place, what is "tracking" and why did this pop -up come out?Therefore, we will explain what this is and what is the case when permitted or does not allow it.

What is tracking?

Tracking is an act of tracking user behavior.Not only smartphones but also web ads and apps are widely performed, collecting information such as individuals and their devices, which websites they have browsed, measuring targeting advertising and advertising effects.It is used.

For example, many people have experienced an advertisement for the product that had been searched earlier when searching for a site that is not related to it is displayed online.right.This is called targeting advertisement and is displayed based on tracking information.

It is hard to say that tracking is good or bad, such as the difficulty of displaying uninterested ads.However, some people may not feel good to get information without knowing.

So, iOS 14.From 5, it is now possible for users to specify whether this tracking is allowed for each app.This is why the pop -ups are now displayed, "Do you want to track your activities across other companies' apps and websites?"

What kind of information does the app track?

In the first place, what kind of information does each app track?In fact, it can be easily checked.

When you open the app page you want to check in the App store, there is an item called [App privacy] at the bottom.The data used for user tracking is the information that the app tracks.

For example, it can be seen that Twitter collects [Purchase], [Contact information], [Browsing history], [Usage data] [location information], and [User content] [ID] for tracking purposes.When you tap the Data used for user tracking, a brief explanation of each item is also displayed.

What happens if you allow/allow tracking?

What are the differences between this tracking, when you are allowed and not permitted?This is the case to briefly describe the advantages / disadvantages of each.

・許可した場合

Benefits: Disadvantages that make it easier to display interesting and interested advertisements: Some application services try to collect more information.

・許可しない場合

Benefits: User information is not collected, and it is easy to display uninterested ads.

If you allow tracking to apps and services, you can collect information such as users' interests and interests, so targeting ads will be displayed and the effects will be measured.Some apps and services try to collect more information more than necessary, so be sure to check what kind of information you will collect when allowed.

On the other hand, if tracking is not allowed, user information is not collected, but advertisements such as websites and apps do not disappear.Since tracking cannot be tracked and targeted advertisements are not available, ads that are not relevant or uninterested may continue to be displayed.If you are a little interested advertisement, you may not be bothered to see it, but you may feel uncomfortable when you see an advertisement that you are not interested in.

How to change the settings later

If you select either [Permit] or [Request to av not to track the app] when a notification for tracking permission is displayed, you can change later.

From "Settings" ▶ [Privacy] ▶ [Tracking], you can select permission / non -permission for each application.The tracking is allowed on (green).

Turn off tracking requests

Instead of setting for each app, the tracking request itself can be turned off at once.

Just turn off the [Apps on the Apps] at the top of [Tracking] ▶ [Privacy] ▶ [Tracking].At this time, if there is an application that has already allowed tracking, the selection of tracking or stopping tracking will be displayed.If you want to stop tracking with all apps, select [Request the app to stop tracking].

If you turn off [App from Apps for Tracking Requests], there will be no notifications to request tracking for each app, and all will be unlimited.Even in this case, it is possible to permit each app later in the previous procedure.

Use properly for each app

Tracking or not depends on your personal way of thinking.It can be used properly, such as permit only the apps that are often used, use only occasionally, or do not allow them with temporary applications.I want you to use this article and use it that suits you.
