One thing that really helped me stop relying on Google for search was when I realised that I could precede any search on DuckDuckGo with `!g` if I didn't find what I wanted on DDG and it would switch to encrypted.google.com
"!g my search term"
"!g my search term"
So Google will still get to log and analyse your search terms, but they will be aggregated with all other users of Startpage - lots of noise.
