You can turn off Gemini Apps Activity in your Google Account settings to stop saving your conversations. You can also delete individual conversations or all your Gemini Apps Activity from your account. When you delete activity, it's removed from your account within a few weeks, but may be retained for a limited time for safety review.
The right to delete your data is meaningful only if deletion is complete and prompt — the delay and safety-review exception create ambiguity about how long your data truly persists after you request deletion, which matters for legal rights under GDPR and CCPA.
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.
