You need to be a newer iOS version to get the native features to limit ad tracking on your iPhone.
Apple lets you limit ad tracking on your iPhone using its native features
Ad tracking has helped businesses grow their understanding about your behaviour, including the potential to buy new items and how you access a particular app or service. Once you're successfully tracked, marketers deliver personalised and targeted ads to incline you towards their offerings. Apple has tried to address this spying nature of companies around the world by introducing a list of privacy-focussed features. You can utilise them to prevent apps and services from ad tracking — to some extent — on your iPhone.
For the last few months, Apple has been quite active in limiting ad tracking on the iPhone. The Cupertino company announced the App Tracking Transparency (ATT) last year to take a step ahead in bolstering user privacy and limiting companies from tracking your activity. The feature rolled out with the release of iOS 14.5 in late April. It also added “nutrition labels” to app listings on the App Store to inform users about what data an app will access upon installation. Further, Apple has enabled the Safari browser to limit tracking through cookies.
Here, we are detailing the steps that you can follow to limit ad tracking from apps and services on the iPhone.
Before beginning with the steps, it is worth noting here that by using ad tracking, developers help companies measure your actions and collect details such as your user or device ID, device's current advertising identifier, name, email address, and other information that help understand your identity. The built-in features are available on the newer iOS versions (iOS 14.5 and later), though you may not find them if your iPhone has a dated iOS release. You can also head to the next section to look at the way to limit ad tracking by Web-based services.
In addition to the above steps, you can also tap Ask App Not to Track on the prompt to block them from tracking your activity and data.
You can follow the below steps to limit tracking from different Web-based services and websites that you visit using Safari on your iPhone.
Although all these steps are helpful in limiting ad tracking on the iPhone, advertisers and companies requiring your personal data often find new ways to track you and keep your profile for their profit motives. You can avoid that further by turning off Background App Refresh for all the apps installed by going to Settings > General and then toggling off 'Background App Refresh'.
Apple also lets you turn off personalised ad delivery on its platform by going to Settings > Privacy > Apple Advertising and turning off the 'Personalised Ads' option.
