Google's support documentation states Gemini app activity \"is used to improve Google services for everyone, including by training generative AI models, if your Keep Activity setting is on,\" and that \"a subset of chats are reviewed by human reviewers,\" though Google claims the transcripts are anonymized. The poster said they learned this too late, having assumed a paid subscription meant their data would not be used for training.", "body_md": "If you have a personal Google AI subscription, all your saved chat history in Gemini can be used for training and there is no way to opt out unless you turn off chat history. These chat transcripts may even read by human reviewers, although Google claims to anonymize them.\n\nhttps://support.google.com/gemini/answer/16836988\n\n*“[Gemini app activity] is used to improve Google services for everyone, including by training generative AI models, if your Keep Activity setting is on.“*\n\nhttps://support.google.com/gemini/answer/13594961\n\nUnder Who has access to my chats, and how does human review improve Gemini for everyone?, Google states:\n*“A subset of chats are reviewed by human reviewers”*\n\nTo disable their training on your chat sessions, you need to turn off “Keep activity” in Gemini’s settings. Turning that off means you’ll lose any chat session after 72 hours.\n\nI learned this too late, thinking that having a paid subscription = not being turned into the product. Apparently paying is not enough.\n\nThank you to this user on HN for mentioning in another thread: https://news.ycombinator.com/item?id=50355424\n\nComments URL: [https://news.ycombinator.com/item?id=50363461](https://news.ycombinator.com/item?id=50363461)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/tell-hn-gemini-trains-on-chat-history-even-for-subscribers-personal-accounts", "canonical_source": "https://news.ycombinator.com/item?id=50363461", "published_at": "2026-11-04 10:10:27+00:00", "updated_at": "2026-11-04 10:20:12.107634+00:00", "lang": "en", "topics": ["ai-policy", "generative-ai", "ai-products"], "entities": ["Google", "Gemini", "Hacker News"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/tell-hn-gemini-trains-on-chat-history-even-for-subscribers-personal-accounts", "markdown": "https://wpnews.pro/news/tell-hn-gemini-trains-on-chat-history-even-for-subscribers-personal-accounts.md", "text": "https://wpnews.pro/news/tell-hn-gemini-trains-on-chat-history-even-for-subscribers-personal-accounts.txt", "jsonld": "https://wpnews.pro/news/tell-hn-gemini-trains-on-chat-history-even-for-subscribers-personal-accounts.jsonld"}}
