Precise and continuous location tracking creates a detailed record of your physical movements, daily routines, home and work addresses, medical appointments, places of worship, and other sensitive locations that can be used for advertising and may be disclosed to third parties including law enforcement via legal process.
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.
