Can other itogai users see my full network?

Your network is private by default. Network sharing is one setting for your whole account (Settings, Privacy, Share my network). It’s off by default and asks you to confirm before it turns on. With it on, other itogai users who have you as a contact can see you as a bridger and ask you for an introduction to someone you know. For that person they see a name, employer, and role, plus the fact that you know them, and nothing else. Your scores, your communication metadata, and your messages are never shown. Switching it off takes effect at once.
