BTW Qwant was also the best single alternative search engine I found too. But it is not Open Source like Searx is, so we need to trust them without the ability to know if it is true. Also it still saves the IP adresses and shares the data with Microsoft:
What data does Qwant collect when I search?
When you search on Qwant, we naturally receive your search terms, as well as the IP address of your computer or mobile device, and information about your browser (the “User Agent”). We use this data to process your inquiry and return your inquiry, as well as the corresponding answers. We pseudonymize what we need to keep for statistics and for transfer to our technology and business partners.
Why are you transferring data to Microsoft, and what data is it?
Microsoft provides some of the search results you see on our pages, and provides ads to the keywords in your search inquiry. This means that we need to send Microsoft some information related to your search that allows our partner to return results and ads relevant to that search, and to prevent fraudulent clicks or other activities that are not permitted by our Terms of Use.
In order to detect fraud, Qwant uses a specialized service offered by Microsoft, which does not have access to the keywords of your search. Only your IP address and the browser (your “User Agent”) are communicated to this specialized service to calculate a fraud probability score. Keywords are sent separately to another service that does not know your IP address.
Processing of our users’ queries
