If you use audio features, we may collect and process voice and audio information when you use audio features, such as voice search, speech-to-text, or Assistant features.
Voice data is biometric in nature and may be subject to heightened legal protections under state laws like Illinois BIPA, and users are often unaware of the extent to which voice recordings are retained, reviewed, or used to improve Google's machine learning models.
Google collects a wide range of personal data including location history, search queries, emails (for feature delivery), browsing activity on third-party sites via Google's ad network, voice and audio data, and device identifiers, combining these across all Google services to build detailed user profiles. This cross-service data combination powers Google's advertising business and means your activity on one Google product can influence what you see on entirely different products and third-party websites. You can review and delete your data, turn off ad personalization, and manage location history at myaccount.google.com/data-and-privacy.
