Disconnect Search is a specialized VPN that lets you search privately using Google, Bing, and Yahoo search engines. They say they don’t log searches, IP addresses, or any other personal info.
Using Disconnect search, your ISP shouldn’t see your search terms as they don’t have access to your searches. Normally, when you click a result link, the site you go to may see your search terms, but Disconnect should prevent this. Search engines save your searches, which can be connected to your real name or IP address. Disconnect should anonymize your searches.
