Stop Your iPhone Apps From Tracking You Now
You can stop apps from tracking you across the internet, so you should see fewer ads following you.

Apple recently released an important security update with?iOS 16.4.1 to help protect you and your data. But Apple also gives you the power to control which iPhone apps can track you and have access to your data.
Apple’s App Tracking Transparency feature gives you more control over which apps can track you on your iPhone and how. Unless you give an app explicit permission to track you (including those made by Apple), it can’t use your data for targeted ads, share your location data with advertisers, or share your advertising ID or any other identifiers with third parties.?
This change, first unveiled at Apple’s Worldwide Developers Conference in 2020 and rolled out with?iOS 14.5, drew?support from privacy advocates?but criticism from companies such as Facebook, which said the move would?hurt its ad business.?
The move came alongside other efforts from Apple to increase transparency as well as privacy, which CEO Tim Cook called a “fundamental human right.” When Apple released iOS 14.3 in 2020, users began seeing app “nutrition labels” informing them of the categories of data an app requests before they download it from the App Store.?
Here’s how to use the new App Tracking Transparency feature to control which apps are able to track you.

How to turn off app tracking on new apps
When you download and open a new app, you’ll get a notification that asks if you want to let the app track your activity across other companies’ apps and websites. You’ll also see information about what the app would track. You can tap?Ask App not to Track?to block that activity or Allow.
When you download an app, you’ll see a notification pop up giving you a choice of whether or not you want to give the app permission to track you.

You can also opt out of app tracking across every app you download by going to Settings > Privacy & Security > Tracking, and toggling off Allow Apps to Request to Track. This means any app that tries to ask for your permission will be automatically blocked from asking and informed that you have requested not to be tracked. And all apps (other than those you’ve given permission to track in the past) will be blocked from accessing your device’s information used for advertising, according to Apple.?
It’s important to note that this doesn’t mean ads will disappear. It just means that you’ll be more likely to see generic ads, not one for that pair of shoes you clicked on one time.?
How to turn off app tracking on already downloaded apps
You can also turn app tracking permissions on or off on a per-app basis.?
To do that, go to Settings > Privacy & Security > Tracking. You should see a list of apps that have requested to track you. Tap the toggle next to the apps you want to stop tracking you.
All app developers are required to ask for permission for tracking. If Apple learns a developer is tracking users who asked not to be tracked, they will need to either update their tracking practices, or else potentially face rejection from the app store.?
Apple believes that privacy features like these are a differentiator for its products. Cook has said that because the company’s business model isn’t built on selling ads, it can focus on privacy.?
Even so, it’s important to bear in mind that when you ask apps not to track you, all you’re essentially doing is prohibiting app developers from accessing the identifier for advertisers, aka IDFA, on your iPhone. Developers use your device’s IDFA to track you for targeted advertising purposes. Denying access to your iPhone’s IDFA doesn’t necessarily mean app developers won’t track you through other means, so it’s critical to be mindful of the apps you use and how you interact with them.?
