I have all these set:

    export CLAUDE_CODE_DISABLE_FEEDBACK_SURVEY=1
    export CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1
    export DISABLE_AUTOUPDATER=1
    # reduces splash screen size:
    export IS_DEMO=1

[skaul]

You can add these to your `~/.claude/settings.json`:

  "env": {
    "CLAUDE_CODE_DISABLE_FEEDBACK_SURVEY": "1",
    "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1",
    "DISABLE_AUTOUPDATER": "1",
    "IS_DEMO": "1"
  }

Ha! Great minds think alike! I posted the same thing 3 seconds slower =(

Just an FYI to several of the posters here.

You CAN set these as env vars in your shell, but I prefer to stick 'em in the Claude settings.json:

  $ cat ~/.claude/settings.json
  {
    "env": {
      "CLAUDE_CODE_DISABLE_TERMINAL_TITLE": "1",
      "CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC": "1"
    }
  }

This keeps your main environment from getting cluttered.

"Added IS_DEMO environment variable to hide email and organization from the UI, useful for streaming or recording sessions"

from the changelog: https://github.com/anthropics/claude-code/blob/main/CHANGELO...

I wasn't even aware that was possible. I will IMMEDIATELY do this. The mere fact this is necessary to stop their data-fiending is disgusting. You prepend it everytime you run Claude or do you slap that into an .env file?

These are good to append to your .bashrc or .zshrc (depending on your shell of choice) and they'll be picked up.

You can also put these into settings.json.

That's why you should always read the manual! These aren't hidden and secret settings:

And, if you really hate manuals, you can just ask Claude to write the settings for you =D

Every time you run it, it uploads most of your project's code to Anthropic's server. That's just how this category of product works. If you're disgusted by a survey...
