Claude Code sends your email address to websites

A GitHub bug report filed as issue #107757 in the Claude Code repository alleges that Anthropic's Claude Code sends the user's email address to arbitrary third-party websites in the User-Agent request header during web searches, without the user's permission. The reporter says the leak has produced dozens of scam emails per day and argues the behavior should be removed from the harness entirely rather than offered as an opt-in or opt-out setting, adding that the company is migrating to Pi with OpenRouter over lost faith in Anthropic preserving its privacy.

Bug Report: Privacy violation in User-Agent header #107757

I receive dozens of scam emails per day because claude code divulged my email to arbitrary 3rd parties in the User-Agent request header while conducting web searches without my permission. This should not be a setting with opt-out or opt-in behavior, it needs to be removed from the harness entirely. It is not for the good of anyone involved: it does nothing for services which dislike agentic traffic, does not preserve my anonymity on the web, and is a goldmine for scammers. I am migrating my company to Pi with OpenRouter since I have no faith in anthropic preserving my privacy.
