If you've ever uploaded a sensitive document, screenshot, or private information to Google Gemini (formerly Bard), you need to watch this! Your private data and uploaded files could be used as training data for the AI, meaning your personal info could potentially show up in other people's answers.

This video shows you the two critical ways to delete history and remove attachments from your Gemini chats and from your entire Google history.

Learn how to erase Google history directly within the Gemini interface or use the powerful Google My Activity tool (myactivity.google.com) to permanently delete your data by time range or product. Protect your privacy and ensure your sensitive information is secure!
