Connected Products and Related Services
Unless otherwise stated, all BYD connected vehicles placed on market in the European Union qualify as connected products within the meaning of Article 2(5) Data Act. A connected product is generally a physical object that obtains, generates or collects data concerning its use or environment and that is able to communicate product data via an electronic communications service, physical connection or on-device access. We also provide related services such as in-car services and mobile applications. For example, the BYD App remote car control service which allows users to remotely manage their BYD vehicle. App capabilities include locking or unlocking the doors of the vehicle, starting the engine, adjusting air conditioning, etc.
Please note that the data in scope is subject to the actual functionalities and configuration of the BYD connected vehicle and the related service. The following data is generally processed from the BYD connected vehicle and related services, such as the BYD APP remote car control service. BYD connected vehicles generally generate data continuously and in real time. The data in scope is subsequently also referred to as “Product Data” and “Related Service Data”.
