How to minimise targeted ads on social media: Uber
It’s tough to minimise targeted ads on phones because ads can be delivered based on data from the device level (such as what operating system your phone is using or based on unique numbers that identify your phone), browser level (what you search for within a browser), and within the apps you use. An app could target ads at you based on your location (tied to your unique device id number(s)) for example. Apps, including Instagram, direct you to opt-out of targeted ads at the device level. Here's how to limit device level tracking.
Uber appears to offer few options to limit data collection and it’s unclear how the data the company has about users is shared with third parties including advertisers, although there have been numerous reports about Uber’s data sharing activities. These screenshots show a few things you can do.
