A tip about migrating to duckduckgo, if you break down with the results and need to go back to google, just add !g to the query and it'll route you forward to google with a redirect. Just be aware, even if you are using DuckDuckGo via the Chrome Omni bar for searching, those results still end up in your Search History on Google (see https://history.google.com/history/ )
Do they manage to collect all that if I never sign-in to Chrome and I never sign in to anything google-related unless it's in a privacy tab? I can't imagine how they would be able to do so given that I'm never signed in, but it wouldn't surprise me if they did somehow.
I am almost never logged in to Amazon, but I've been noticing for awhile that they still recommend things to me, and they say up front "based on something or other to do with your Amazon activity." The only thing they don't do is call me by name when I'm not logged in. But they obviously know it's me.
As a result I'm on DDG + Firefox at this point
