why did google assistant delete what she heard about my search history?

Google Assistant, like other voice assistants, takes privacy and data security seriously. Although I am an AI language model and don't have access to real-time information, I can provide a general explanation. Google Assistant does not "delete" what it heard about your search history because it doesn't have the capability to remember or record your search history.

When you interact with Google Assistant, it listens for the activation phrase and processes your voice command or query. It then sends the audio recording of your command or query to Google's servers for processing. This audio recording is used to provide you with a response and improve the accuracy of Google Assistant's voice recognition technology.

However, Google provides options for managing your privacy and deleting your search history. You can access and control your activity and history settings through your Google account settings. This allows you to review and delete the search history associated with your Google account. Remember to check your specific Google account settings for personalized control over your data.
