The phone in your pocket features a unique “Advertising ID” that lets advertising companies track your app activity. While you can’t remove this ID, you’ll reset it to erase all of your activity.
Advertising IDs are present on iPhones, iPads, Windows PCs, and Android devices. They work similarly to “cookies” in web browsers. Your activity is tracked, shared—and sometimes sold—and then wont to deliver up ads that you’re more likely to click.

You can’t remove or disable the advertising ID entirely. the simplest that you simply can do is to “reset” the ID. This wipes the slate clean, and if you are doing it regularly, you won’t build up an enormous log of data . you’ll also cop out of personalized ads.
First, swipe down from the highest of the screen once or twice, then tap the gear icon to open the Settings menu.
Scroll down and select the “Google” settings.
Next, select “Ads.”
Tap “Reset Advertising ID.”
Select “OK” from the confirmation pop-up.
Toggle the switch on for “Opt Out of Ads Personalization.”
Select “OK” from the confirmation pop-up.
That’s all there’s to it! Getting ads that are more likely to be relevant to your interests won’t sound awful, but there are obvious privacy concerns involved. You’ve taken back a touch little bit of your privacy.
