I use DDG on desktop but on mobile they are unusable. Their app displays three ads out of 4 results in a page. A simple typo gives me completely different results.
I will continue to hope there is some kind of subscription to Google search without tracking and all.
About the tracking part, you may like to check Whoogle Search - https://github.com/benbusby/whoogle-search It's Google results without the tracking, and it can be self-hosted.
