The game regularly sends data to "tracking2.avalanchestudios.com", so you can block whatever is getting sent there by editing your hosts file if you're using Windows. If you're on linux, you can probably just blacklist the ip address "104.18.66.114"


To edit the hosts file, you'll need to open a text editor such as notepad as an administrator, you can do that by right clicking it in your start menu.













Once it's open, you're gonna need to click "File -> Open" from your buttons at the top left, and then navigate to C:\Windows\System32\drivers\etc, change the "text documents" dropdown on the bottom right to "all files", and open up the hosts file.








Then simply add the following below the commented examples.






This will redirect the data back to your computer, essentially going nowhere.
Like I mentioned, I don't really know what data they're collecting like this, but if it makes you feel better, this is a simple way of blocking it.
