Gemini Personal Subscriptions Still Use Chat Logs for Model Training

Google Gemini's paid personal subscription accounts still use saved chat histories to train AI models by default, as paying does not automatically opt users out of data collection. To opt out of model training, users must turn off Keep Activity in settings, which limits chat history retention to just 72 hours. Furthermore, some conversations undergo human review and can be kept for up to three years, with official support documentation explicitly warning users against entering confidential information.
