Because your internet traffic at home moves to and from your devices through your internet service provider — ISP for short — they can see where you go online. An ISP can see what sites you visit, how long you’re on them, your location and information about your devices. An ISP may not know the specifics of what you did on those sites (like what you bought, searched for or read) thanks to encryption, but they could make inferences about you based on the sites that you visited. That personal data can be used by ISPs to create detailed profiles about you. Browsing in private mode doesn’t prevent ISPs from seeing where you go online. But sending your web traffic through a VPN can make it much harder.

因为您在家中的互联网流量通过您的互联网服务提供商（简称 ISP）进出您的设备，他们可以看到您上网的位置。 ISP 可以查看您访问了哪些站点、您在这些站点上停留了多长时间、您的位置以及有关您设备的信息。由于加密，ISP 可能不知道您在这些站点上所做的具体操作（例如您购买、搜索或阅读的内容），但他们可以根据您访问的站点对您进行推断。 ISP 可以使用这些个人数据来创建有关您的详细资料。以私密模式浏览并不会阻止 ISP 看到您上网的位置。但是通过 VPN 发送您的网络流量可能会使其变得更加困难。
