i see that you haven't read their linked Privacy policy

To provide relevant results when we do not have the answers to your queries ourselves, we have a partnership with Microsoft to provide our search results and contextual ads based on the entered keywords and your geographic region.

For this purpose, Qwant can transfer the following pseudonymized data to this partner related to your query:

 Search keywords,
 Information about the browser you are using,
 The first three bytes of your IP address or, in the case of a User Account, the IP address,
 The approximate geographic area originating the search on a regional or city level,
 The salted hash generated from your IP address, User Agent, and a salt changing at least every 3 months,
 A random token generated by Qwant (aiming to limit data cross-referencing).

Additionally, for the security and reliability of our partner’s services (spam detection, automated activity, fraudulent ad clicks), Qwant may also collect and transfer your full IP address to this partner.

Finally, as part of providing new features, Qwant shares your IP address with Microsoft to provide you with contextual ads and better search results.
