I didn't investigate how to run the backend server (is its address configurable?) but if it can be self hosted it could be run locally. The advantage is that VMs and maybe even containers can send their history to the local server.

If it can't be self hosted, despite end to end encryption it's a big no no for me.

Edit. I read the code

  func getServerHostname() string {
    if server := os.Getenv("HISHTORY_SERVER"); server != "" {
      return server
    }
    return "https://api.hishtory.dev"
  }

Same. This tool would've been much better if it didn't reinvent syncing, functioned entirely offline, and just focused on the core problem of contextual shell history. There are plenty of syncing tools that handle security well, and the author could've recommended some that integrate well with this project.

As it is, this is a blocker for me even trying it out. Even if it could eventually be disabled, I don't want it to have network access at all.

This isn't supported quite yet, but is the next item on the road map.
