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.

由於您在家中的網路流量會透過網際網路服務供應商 (又稱 ISP) 與您的裝置匯入或匯出您的裝置。他們會發現您會在哪裡上網。 ISP 可以看到您造訪哪些網站、開啟這些網站多久、您的所在位置以及關於您的裝置的資訊。透過加密系統ISP 可能不知道您在這些網站做了什麼例如您買了哪些東西、搜尋了哪些東西但他們可以根據您造訪過的網站來推測您。您的個人資料可能會被 ISP 用來建立您的詳細資料。在隱私瀏覽模式中上網並不會讓 ISP 知道您經常去哪裡上網。但透過 VPN 傳送流量會讓事情變得更難。
