Don't get me wrong, I like the idea of not using Google, but this seems like a very user hostile way to do it.
I would prefer conscious filtering to this automated (and obscure) filtering that Google et al. utilise. I understand it's not for everyone, but it would suit me far better.
Now if you had an ML algorithm running in your browser that analyzed your preferences and transparently changed your DDG searches from "Django" to "Django web framework", you might get something closer to what you get with Google. Wonder if Firefox could make that happen.

With cloud save, you pick a password, and have to type that in once on each device.
They don't support bubbling, or user profiling, so you can't dump/restore those.
I think the parent poster was asking for a feature more like "I use LaTeX to document Django. This is all you should know about me. Go."
Put another way, can I fill that form out, create a google search bookmarklet that encodes my responses client-side, and then use it with all google cookies and ad domains blocked?
What if DDG allowed us to manually tell them information about our demographic in a way that wasn't stored on their servers and could be changed at will? If you want convenience, maybe there could be an optional client-side preference detector script that only offered possible configurations.
