iOS 13 app tracking alert has dramatically cut location data flow to ad industry
Although it doesn't stop DNS over HTTPS, I use a DNS sinkhole on my home network and then I use wireguard to VPN into home when I'm not connected to my home WiFi.<p>The Wireguard iOS app allows you to automatically connect to your configured interfaces based on whether you're using cellular data, connected to specific SSIDs, or disconnected from specific SSIDs.<p>The only downside I have found to this approach so far is that it can break captive portals on public WiFi networks, which I will just disconnect from if I have a reasonable 4G signal.
