Your conversations with Gemini may be used to improve Google's AI models. This includes using conversations to train, develop, and improve Google products and services. You can turn off Gemini Apps Activity to prevent your conversations from being used for model training.
An opt-out model for AI training data use means most users' conversations contribute to AI model development without their active knowledge or consent, which raises significant concerns under GDPR's requirements for a valid lawful basis for processing.
Every conversation you have with Google Gemini is stored by Google for up to 18 months by default and may be read by human reviewers for safety and quality purposes, meaning sensitive personal information shared in chats could be accessed by Google employees. Your Gemini conversation data may also be used to train and improve Google's AI models unless you opt out, creating a persistent data footprint that extends well beyond the immediate session. You can turn off Gemini Apps Activity at myactivity.google.com to stop future conversations from being saved, and you can delete past conversations from your Gemini activity history on that same page.
