I use KISS Launcher.

Olauncher is open source, and really fast.

I use neolauncher, it is pretty good even though it is in its early days. It is also avaliable on izzyondroid.

I just use plain built-in Trebuchet, and I can't think of any privacy issues related to it

I love using the lynx launcher, zero trackers and it can incorporate arcticons too. Worth a try without question!

I use minimalist mLauncher from f droid is simple, minimalist and I spend less time on phone because phone didn't make any distraction.

I have been using Discreet Launcher for some time now. It's fast and and distraction-free. https://f-droid.org/en/packages/com.vincent_falzon.discreetlauncher/

Any launcher without internet access 🙂 For me it is Niagara launcher, really awesome!
