Brave Search includes unique features such as [Discussions](https://search.brave.com/help/discussions), which highlights conversation-focused results—such as forum posts.
We recommend you disable [Anonymous usage metrics](https://search.brave.com/help/usage-metrics) as it is enabled by default and can be disabled within settings.
**DuckDuckGo** 最主流的隱私搜尋引擎選項之一。 Notable DuckDuckGo search features include [bangs](https://duckduckgo.com/bang) and a variety of [instant answers](https://help.duckduckgo.com/duckduckgo-help-pages/features/instant-answers-and-other-features). The search engine uses numerous [sources](https://help.duckduckgo.com/results/sources) other than Bing for instant answers and other non-primary results.
DuckDuckGo is the default search engine for the [Tor Browser](tor.md#tor-browser) and is one of the few available options on Apple’s [Safari](mobile-browsers.md#safari) browser.
DuckDuckGo 提供兩種 [其它版本](https://help.duckduckgo.com/features/non-javascript) 搜尋引擎，兩者皆不需要JavaScript。 然而，這些版本缺少特色。 These versions can also be used in conjunction with their Tor hidden address by appending [/lite](https://duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion/lite) or [/html](https://duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion/html) for the respective version.
Startpage 大股東是System1，它是一家廣告技術公司。 我們不認為這是問題，因為他們有明顯分開的 [隱私政策](https://system1.com/terms/privacy-policy)。 The Privacy Guides team reached out to Startpage [back in 2020](https://blog.privacyguides.org/2020/05/03/relisting-startpage) to clear up any concerns with System1's sizeable investment into the service, and we were satisfied with the answers we received.
Startpage previously placed limitations on VPN and [Tor](tor.md) users, but they recently created an [official](https://support.startpage.com/hc/en-us/articles/24786602537364-Startpage-s-Tor-onion-service) Tor hidden service, and as of April 2024 we have no longer noticed extra roadblocks for Tor or [VPN](vpn.md) users.
A [metasearch engine](https://en.wikipedia.org/wiki/Metasearch_engine) aggregates the results of other search engines, such as the ones recommended above, while not storing any information itself.
