Is Claude Helper safe?

Low risk

Claude Helper loads Google Fonts on claude.ai pages, sending page request context to Google font endpoints.

When a Claude page loads, Claude Helper adds a Google Fonts stylesheet to the page for the Be Vietnam Pro font. The browser requests the stylesheet and font assets from Google, which receive network details such as the user's IP address and referrer or page URL context.
