Recital 34

The use of a connected product or related service may, in particular when the user is a natural person, generate data that relates to the data subject. Processing of such data is subject to the rules established under Regulation (EU) 2016/679, including where personal and non-personal data in a dataset are inextricably linked. The data subject may be the user or another natural person. Personal data may only be requested by a controller or a data subject. A user who is the data subject is, under certain circumstances, entitled under Regulation (EU) 2016/679 to access personal data concerning that user and such rights are unaffected by this Regulation. Under this Regulation, the user who is a natural person is further entitled to access all data generated by the use of a connected product, whether personal or non-personal. Where the user is not the data subject but an enterprise, including a sole trader, and not in cases of shared household use of the connected product, the user is considered to be a controller. Accordingly, such a user who as controller intends to request personal data generated by the use of a connected product or related service is required to have a legal basis for processing the data as required by Article 6(1) of Regulation (EU) 2016/679, such as the consent of the data subject or the performance of a contract to which the data subject is a party. Such user should ensure that the data subject is appropriately informed of the specified, explicit and legitimate purposes for processing those data, and of how the data subject may exercise their rights effectively. Where the data holder and the user are joint controllers within the meaning of Article 26 of Regulation (EU) 2016/679, they are required to determine, in a transparent manner by means of an arrangement between them, their respective responsibilities for compliance with that Regulation. It should be understood that such a user, once data has been made available, may in turn become a data holder if that user meets the criteria under this Regulation and thus becomes subject to the obligations to make data available under this Regulation.
