Millions of (very) private chats exposed by two AI companion apps

**Executive summary:** Two AI companion apps (Chattee Chat and GiMe Chat) developed by Imagime Interactive Limited exposed private conversations, NSFW media, IP addresses, and device identifiers for over 400,000 users (about 43 million messages and 600,000+ images/videos) due to a publicly exposed, unauthenticated Kafka broker; the leak was closed after responsible disclosure but creates significant privacy, sextortion, and targeted-abuse risks for affected users.
