Barinsta got DMCAed or something, F-Droid page is up [1] but the GitHub (linked from there) isn't, and the F-Droid package is still from last summer 2021.
I use a Pi-Hole in my LAN, and Wireguard to it. Low latency so works very well, and given it has a killswitch my connection is always secure -- public WLAN or WAN be damned. The downside is my device and all apps have access to my LAN. Although some of my devices are on a DMZ, and the Pi-Hole works from there as well but the rest of the LAN not.
