Claude chats exposed in Google searches – another endorsement of Apple’s privacy approach

Public Claude chats shared through Anthropic’s link-sharing feature were found via Google search, exposing hundreds of conversations with sensitive personal and work details.

The likely cause was missing noindex protection on shared pages, allowing search engines to index links users assumed were only accessible by URL.

Anthropic said shared chats were meant to be public, but the unexpected discoverability led users to stop using the feature and delete past shared chats.

The episode underscores how AI chat-sharing features can leak private information through search indexing and why privacy-first design matters.
