Tell HN: Gemini trains on chat history, even for subscribers (personal accounts)

AI-generated summary

Google Gemini's personal accounts, even those with paid subscriptions, use chat history for AI model training. Users cannot opt out unless they disable chat history or use temporary sessions, and these transcripts may be reviewed by humans. While Google claims to anonymize reviewed chats, they warn against entering confidential information due to potential retention of up to three years.
