Some were relatively harmless, like this conversation about birds, but others included revealing personal details\n\nTo keep your conversations secure, Claude users can go to Settings, Privacy, Shared Chats to manage access or 'unshare' the conversations to keep the contents private.\n\nAn Anthropic spokesperson told the Daily Mail: 'We give people control over sharing their Claude conversations publicly, and in keeping with our privacy principles, we do not share chat directories or sitemaps with search engines like Google.\n\n'These shareable links are not guessable or discoverable unless people choose to share them themselves.\n\n'When someone shares a conversation, they are making that content publicly accessible, and like other public web content, it may be archived by third–party services.'", "url": "https://wpnews.pro/news/urgent-warning-to-claude-ai-users-as-hundreds-of-chats-are-found-publicly-online", "canonical_source": "https://www.dailymail.com/sciencetech/article-16010773/Urgent-warning-Claude-AI-users.html?ns_mchannel=rss&ns_campaign=1490&ito=1490", "published_at": "2026-07-28 15:08:24+00:00", "updated_at": "2026-07-28 15:28:20.974986+00:00", "lang": "en", "topics": ["ai-safety", "ai-products", "ai-policy"], "entities": ["Anthropic", "Claude AI", "Google", "Reddit", "Wired", "Bing", "Brave"], "alternates": {"html": "https://wpnews.pro/news/urgent-warning-to-claude-ai-users-as-hundreds-of-chats-are-found-publicly-online", "markdown": "https://wpnews.pro/news/urgent-warning-to-claude-ai-users-as-hundreds-of-chats-are-found-publicly-online.md", "text": "https://wpnews.pro/news/urgent-warning-to-claude-ai-users-as-hundreds-of-chats-are-found-publicly-online.txt", "jsonld": "https://wpnews.pro/news/urgent-warning-to-claude-ai-users-as-hundreds-of-chats-are-found-publicly-online.jsonld"}}
