A recent Washington Post article describes how advertising companies can track iPhone phone users, even while they sleep, to gather information about their shopping preferences.
User data is an important commodity these days, with the proliferation of smart devices and the desire of advertisers to reach as many phones as possible for marketing products.
Although Apple's emphasis on the privacy of its users, this privacy seems to be infiltrated by advertisers. But there are some simple ways to minimize ad companies tracking you on your smartphone.
From these methods, go to the Settings box, select "Privacy", then click "Ad" (at the bottom of the Settings screen) and turn on "Ad tracking limit."
Advertisers can use a system called "fingerprint" to track information about your device type, model, and other data that is monitored by your browser.
Fingerprint is not useful to marketers, but can still provide a lot of interesting information.
While Apple is blocking this information, many are still available to marketers.
If you are a browser "Safari" on the iPhone device, many sites will ask you to approve the use of what is known as "cookies" (cookies), and is to approve it as a partial abandonment of privacy.
To protect your device from such a procedure, go to the Settings option, click the Safari option, scroll down to the Privacy and Security section, and turn on the "Prevent cross-site tracking" option.
If you do this, advertisers and third-party content providers can not track you from one site to another.
