You can request for websites to not keep track of your activity when using Chrome
When you browse the Internet, the sites you visit pick up bits of information about you and your online habits. Some information, like websites you’ve visited, may be shared with third parties. Those third parties may use the information for advertising or gathering reporting statistics. You can request for that information to not be be tracked, and therefore not shared. However, as we discuss below, a website may or may not honor that request. Keep in mind that we’re not trying to spread Fear, Uncertainty and Doubt; we’re just trying to let you know what your options are.
We’ll be talking about how to set "Do not track" when using Chrome on your Android device.
