So to clarify I have heard, that DDG is not enough for Privacy and still has some loopholes, for example: DDG uses Amazon to host there Servers, Bing for there search quires and the sades part about this is that DDG uses the V2 Onion links, instead of the V3 ones.
StartPage is owned by a for profit advertisment company and also uses Amazon hosting to host there website.
Qwant is malicious to Tor users by forcing them to do a CAPTCHA, that does not even work and this all is of course all hosted on Amazon Servers.
So are the other Search Engines that really respect your privacy and use there own search queries?
Please do not suggest me: Bravesearch, Mojeek, Peekier, Gibiru or Searx, because those are all have the same flaws as the 3 main privacy search engines above (Searx is not a search-engine.)
ohh well, DDG also is more of a meta-search engine, getting stuff mainly from Bing, so I wouldn’t go as far as rejecting FLOSS meta-search engines such as Searx but accepting DDG, see:

BTW, no privacy oriented search engine with all indexes of its own will give you good results as of now, that I know of. So whether a mixture of a private oriented meta-search engine with its own indexes, FLOSS, might become a good alternative. DDG mainly as a meta-search engine doesn’t even give you the control Searx provides to you, as to where to get the search results from.
Another side effect of DDG, is being a non FLOSS per profit project, based on US (with all US regulations applying).
So perhaps not the answer you were looking for, but to me, Searx, whether self hosted or using instances out there (even better if out of the extended 5 eyes, just in case), is currently what I settled to for search engine, :)
