Using VPN or anonymizer can make it very difficult or impossible to view a person’s browsing history by third parties. A virtual private network (abbreviated as VPN) encrypts your connection and sends it through a number of servers across the globe, and thus conceals your real IP address and location. Anonymizers are based on a similar principle by hiding your network and location data from websites. However, it should be noted that these tools are meant to ensure your privacy and anonymity on the web, and they are not supposed to save your browsing history. On the other hand, browsing history can be saved on your device, in a browser, or in the memory of your device even if you use a VPN or anonymizer. In some cases, if your Internet service provider or network administrator uses traffic analysis protocols, they can see that you are using VPN or anonymizer, but they won’t be able to view your browsing history.
