Gemini Apps Activity is saved to your Google Account for 18 months by default. You can change this to 3 months or 36 months, or choose to not save your Gemini Apps Activity to your Google Account at all. For users who are under 18, Gemini Apps Activity is saved for 18 months by default and can only be changed to 3 months.
Many users assume deleted conversations are gone immediately, but Google retains this data for extended periods which affects your privacy and what information about you Google holds.
Using Google Gemini means your conversations — including any personal details you share — are stored for up to 3 years and may be read by Google employees for safety and quality purposes. Your chat history being deleted from your account does not necessarily stop Google from retaining associated data for AI training, which is a significant privacy implication many users would not anticipate. You can limit data retention by visiting myactivity.google.com, navigating to Gemini Apps Activity, and changing or disabling the auto-delete settings.
