On July 25, a Reddit user searched
site:claude.ai/share and pulled up hundreds of strangers' Claude conversations — wallet seed phrases, apparent Social Security numbers, private legal questions. The cause: a missing noindex tag. Share links were meant to be unlisted, but without that crawler instruction, any link posted publicly became an indexed page.By July 26 Anthropic patched it, Google cleared the results. Bing is still surfacing links — and a GitHub repo has already archived 453 chats, 11,241 messages in plain text. That copy isn't going anywhere.
Settings → Privacy → Shared Chats kills future access. What's already saved is already saved.
