The recommendations here do not collect personally identifying information (PII) based on each service's privacy policy. Não existe **qualquer garantia** de que estas políticas de privacidade sejam respeitadas.
**Brave Search** is a search engine developed by Brave. It 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.
O **DuckDuckGo** é um dos motores de pesquisa mais comuns, no que toca à privacidade. 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-ios) browser.
DuckDuckGo offers two [other versions](https://help.duckduckgo.com/features/non-javascript) of their search engine, both of which do not require JavaScript. No entanto, estas versões carecem de funcionalidades. 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.
**Mullvad Leta** is a search engine developed by Mullvad. It uses a [shared cache](https://leta.mullvad.net/faq#what-is-cached-search) to fetch search results and limit calls to the search APIs it uses.
Mullvad Leta currently only provides text search results. It is the default search engine for the [Mullvad Browser](desktop-browsers.md#mullvad-browser).
Mullvad Leta is useful if you want to disable JavaScript in your browser, such as [Mullvad Browser](desktop-browsers.md#mullvad-browser) on the Safest security level.

Mullvad Leta was [audited](https://mullvad.net/en/blog/security-audit-of-our-letamullvadnet-search-service) by Assured AB in March 2023. All issues were addressed and fixed shortly after the [report](https://assured.se/publications/Assured_Mullvad_Leta_pentest_report_2023.pdf).
**Startpage** is a private search engine. One of Startpage's unique features is the [Anonymous View](https://startpage.com/en/anonymous-view), which puts forth efforts to standardize user activity to make it more difficult to be uniquely identified. The feature can be useful for hiding [some](https://support.startpage.com/hc/articles/4455540212116-The-Anonymous-View-Proxy-technical-details) network and browser properties. Ao contrário do que o nome sugere, esta funcionalidade não deve ser utilizada para garantir o anonimato. Se procura anonimato, utilize o [Browser Tor] (tor.md#tor-browser).
O acionista maioritário do Startpage é a System1, uma empresa marketing tecnológico. Não acreditamos que isso constitua um problema, uma vez que têm uma [ política de privacidade](https://system1.com/terms/privacy-policy) separada. 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.
O SearXNG funciona como um proxy entre si e os motores de busca que agrega. As suas consultas de pesquisa continuarão a ser enviadas para os motores de busca, sendo os resultados obtidos pelo SearXNG.
Ao usar a auto-hospedagem, é importante as outras pessoas utilizem a sua instância, de forma a que as consultas sejam integradas. Deve ter cuidado com o local e a forma como aloja o SearXNG, uma vez que as pessoas que procuram conteúdos ilegais na sua instância podem chamar a atenção indesejada das autoridades.
Quando estiver a utilizar uma instância do SearXNG, certifique-se de que lê a política de privacidade. Uma vez que as instâncias do SearXNG podem ser modificadas pelos seus proprietários, não é garantido que sigam a sua política de privacidade. Algumas instâncias são executadas como um serviço oculto Tor, o que pode garantir alguma privacidade, desde que as suas consultas de pesquisa não contenham informações pessoais.
