alt Hacker NewsI use Rethink DNS for this, see (https://github.com/celzero/rethink-app).
Despite it's name it can also block IPs and specific apps from connecting to specific servers. I use it to block all manufacturer and OEM related apps that I cannot uninstall through adb or disable. Very handy for blocking constant Chinese phone telemetry pings, as well as additional network level blocklists for ads (Pi-hole like), completely locally so you can trust it unlike a shady VPN.
I checked out your link; it seems to be a mailing list for a hosts file for telemetry? Why is there no option to just see the file without giving in my email? Not the most private.

You're right, our Telemetry Blocklist is a mailing list for a hosts file. I can offer you the list directly, no email required. Just visit https://raw.githubusercontent.com/lightinthedarksolutions/te... and copy the file to your device. This will block common telemetry servers without any external dependencies.
I love rethink but stopped using it on my up-to-date GOS. It randomly stops and no app can reach the internet (or me), randomly it doesn't obey the split tunneling rules or doesn't forward the connections to the tunnel at all (thus blocking all internet if wg proxy is enabled), and couple of other things.
I'll check Rethink again because all in all it's a fantastic software, just doesn't work very stable for me.
