However, this changed in 2013 with the creation of the “ad ID”: both Android and iOS unveiled a new persistent identifier based in software that provides the user with privacy controls to reset that identifier at will (similar to clearing cookies). Thus, there wasn’t an easy way for users to do the equivalent of clearing their cookies.
Many apps used (and still use) the Android ID for tracking purposes, which while not based in hardware, can only be reset by performing a factory reset on the device and deleting all of its data.

Regarding the persistent identifiers used by mobile apps, up until a few years ago, there was no way of doing the equivalent of clearing your cookies: many of the persistent identifiers used to track your mobile app activities were based in hardware, such the device’s serial number, IMEI, WiFi MAC address, SIM card serial number, etc. Clearing your cookies resets all of the persistent identifiers, which means that new persistent identifiers will be sent to third parties, making it more difficult for them to associate your future online activities with the previous profile they had constructed. On the web, if you don’t want to be tracked in this manner, you can periodically clear your cookies or configure your browser to simply not accept cookies (though this breaks a lot of the web, given that there are many other uses for cookies beyond tracking). This sort of profiling is what is meant by “behavioral advertising.” That is, they track your behaviors so that they can infer your interests from those behaviors, and then send you ads targeted to those inferred interests. When a different app on your same phone sends that same advertising network your device’s serial number, that advertising network now knows that you use both of these apps, and can use that information to profile you. For example, one app might send an advertising network your device’s serial number.
On your mobile device, there are many different types of persistent identifiers that are used by app developers and third parties contacted by those apps.
Your Social Security Number and phone number are examples of persistent identifiers used in real life cookies use persistent identifiers to identify you across websites. A persistent identifier is just a unique number that is used to either identify you or your device. They allow companies to learn the websites that you visit and the apps that you use, including what you do within those apps. Persistent identifiers are the bread and butter of the online tracking industry. Published by Serge Egelman on FebruFebruThe Ad ID
