France has a more permissive surveillance regime than the US[0], and as a foreign (US) user I have no recourse if they spy on me.

Furthermore, here are some quotes from qwant:

>We do not use any cookies or other advertising tracers to create your profile for commercial purposes. This means that you can use Qwant with confidence, we will never try to establish your psychological or commercial profile to sell it to third parties, here or elsewhere. [1]

Note the "for commercial purposes" in the first sentence, and the "to sell it to third parties" in the second. These are weasel clauses.
