Your router is gathering information.

Wi-Fi router manufacturers assert that they do not track the websites you visit, but all collect and share some user data. Here's what you need to know and how to safeguard your privacy.
Since the Wi-Fi router in your home serves as the central hub of your home network, all Wi-Fi device traffic going to the cloud passes through it.That is a significant amount of data—enough to raise legitimate concerns about privacy when selecting one.
The issue is that it is nearly impossible for the average consumer to learn much about the router manufacturers' privacy policies.The majority of privacy policies do a poor job of shedding light on data collection practices because they are initially complicated.It is not an easy task for a single manufacturer, much less for several of them, to find the motivation to read through the lengthy legal jargon that is included in them.Even if you get that far, you probably won't have enough information to answer all of your questions.
