You can stop getting ads that are based on your interests and info.

 

To turn personalised ads off open your device Settings.

 

Scroll down and select the "Google" option. Depending on your device, this entry may not be on the main page, but you can use the search feature at the top of the Settings menu to find it. From there, choose "Ads," then enable the switch next to "Opt out of Ads Personalisation."

 

Now, your advertising ID won't be used by apps on your phone to build advertising profiles based on your usage. Enabling this setting will also prevent apps from displaying targeted ads. You are still tracked by Google, but random ads are shown instead.
