Cross-device tracking refers to the practice of monitoring and recording a user’s online activities across multiple devices, such as smartphones, tablets, and computers. This allows companies and advertisers to create a comprehensive profile of a user’s behavior and preferences, regardless of the device they are using. By tracking a user’s interactions and movements across devices, cross-device tracking enables businesses to deliver targeted and personalized advertisements, improve user experience, and gather valuable insights for marketing purposes. However, it has also raised concerns about privacy and data protection, as it involves collecting and sharing sensitive information about individuals without their explicit consent.
