Tell HN: Gemini trains on chat history, even for subscribers (personal accounts)
Summary
The Hacker News post highlights that Gemini can train on users' chat histories even for personal-paid accounts. It explains how transcripts may be reviewed by humans and retained, with opt-out only by disabling Keep Activity, which can result in losing chats. It also cites Google support pages warning users not to share confidential information and noting data usage for model training.
