In 2019 it was revealed that several providers of voice assistants had systematically evaluated voice recordings of their users. Since the data protection notices stated that data would also be used to improve the service, this use was legal. For the users, however, this evaluation represented a clear break with their expectations of privacy. The purpose limitation principle of the GDPR with its component of purpose specification requires flexibility for the processor as well as transparency for the consumer. Against the background of this conflict of interest, the question arises for HCI as to how processing purposes of voice assistants should be designed to meet both requirements. To collect a user perspective, this study first analyzes the data protection information of the dominant voice assistants. Based on this, we present results of focus groups that deal with the perceived processing of data of voice assistants from the user perspective. The study shows that exi sting purpose statements offer hardly any transparency for consumers regarding the consequences of data processing and do not have any restrictive effect with regard to legal data use. Our results on risks perceived by users allow us to draw conclusions about the user-friendly design of processing purposes in terms of a design resource.
