For Workspace accounts, admins can configure retention settings. Even after deletion, conversation data may be retained for a safety and quality review period.
An 18-month retention window means your AI conversations — which may include sensitive personal, medical, or financial details — are stored far longer than most users would expect, and persist even after account deletion.
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.
