Swisscows is a search engine that presents itself as a privacy alternative. It says it does not store user data, anonymises all search queries and creates no user profiles. It uses semantic search, offers an anonymous preview window for result pages, and leaves out explicit content as a family-friendly engine. According to Wikipedia, web results come from Bing, with an own index built for the German-language edition.
Swisscows was launched in 2014 by Hulbee AG, based in Egnach, Switzerland; the site's copyright notice names Swisscows AG. Reporting from 2018 says the servers sit in a Swiss data centre operated by Mount10 in a bunker in the Alps, outside both the EU and the US. Because web results are drawn from Bing, a US-operated service, that upstream dependency deserves attention. The service is hosted by the provider and is not open source.
