Taskwarrior, tried lots and lots of ones but always come back to Taskwarrior. It just works the way my brain does, and has tons of features that I actually use because they are intuitive and easy to remember how to.

It’s not useless, it removes a lot of the tracking cookies and such and sponsored links loaded with telemetry. Theoretically you can also get the benefits of anonymity if you proxy through Tor or a VPN, which I originally tried to do but turns out Google at least blocks requests from Tor and at least the VPN endpoint I have and probably most of them. Google or whatever upstream SE can still track you by IP when you self host, but its tracking is going to much less without the extra telemetry cookies and tracking code it gets when you use Google results directly.

But yes, practically you either have to trust the instance you’re using to some extent or give up some of the anonymity. I opted to self host and would recommend the same over using a public instance if you can, personally. And if privacy is your biggest concern, only use upstream search providers that are (or rather, claim to be) more privacy respecting like DDG or Qwant. My main use case is primarily as a better frontend to search without junk sponsored results and privacy is more of a secondary benefit.

FWIW, they have a pretty detailed discussion on why they recommend self-hosting here.

I’ve always gotten the impression it was mostly intended to be self hosted. I’ve self hosted it for something like a couple years now, runs like a clock. It still strips out tracking and advertising, even if you don’t get the crowd anonymity of a public instance.
