Mozilla didn't choose privacy. Qwant sends you IP address to Microsoft when you search on their platform. If you want a more responsible search engine, DuckDuckGo is still the way to go.
Update 3: DuckDuckGo also sends along more information than I originally noticed, including "anonymous browser and device information with our hosting and content providers for security and display purposes (for example, that you’re using a mobile device)"
The information collected by Qwant includes...
- hash of the IP address
- User Agent
- market segment of a request
- date and time of the visit
- information of the country and the chosen language
- search keywords
- where a user came from
- type of device used
- source of visit
- operating system
- major browser version
Qwant may (will) transfer to Microsoft:
- your full IP address
- Information about the browser you are using (the User Agent
- The first three bytes of your IP address;
- The approximate geographic area at the origin of the search, at the scale of a region or city;
- The hash generated from your IP address and User Agent
Update 2: removing name and email as that's only for optional account creation
