What is the most private search engine?

The most private engine is one that stores nothing: no query logs, no history, no profile. DeepIncognito is built to that standard and adds erase-first behaviour - results are temporary, sessions auto-destruct, and one tap wipes the screen.

Is Startpage private?

Startpage proxies Google results without logging queries, which is a genuine improvement over searching Google directly. It has no erase-first or auto-destruct behaviour.

Are Google and Bing private search engines?

No. Both retain search activity and use it for personalisation and advertising, whether or not you are signed in.

Private search engines compared

Every engine calls itself private. The differences that matter are narrow and testable: does it log the query, does it build a profile, and can you make the results disappear? Here is where four options land.

How to judge any private engine

Ask three questions. Does it retain the query text, and for how long? Does anything about the search persist on your device? Can you remove what is on screen instantly, without hunting through settings? An engine that answers well on all three is private in practice, not just in marketing.

Where DeepIncognito differs

Most private engines stop at "we do not log." DeepIncognito treats the visible session as part of the threat model: results are shown temporarily, the session self-destructs after inactivity, and the erase control dissolves everything on screen the moment you want it gone.
