The updated Privacy Policy now explicitly discloses that Synthesia collects voice, video, image, and text inputs when users interact with the company's demo experiences, whereas the prior version only mentioned voice and text inputs. The policy also clarifies that Synthesia acts as a data controller of Other Information used to operate its platform and business. These changes formalize the scope of data collection and Synthesia's processing role, but do not appear to introduce new collection practices—rather, they expand the transparency of existing operations.
View change record →The updated policy now explicitly states that Synthesia collects voice and text inputs when users interact with demo experiences, and processes 'other information you choose to provide' for both service delivery and internal research to improve the platform and AI models. This clarifies what personal data is collected during demo and roleplay interactions and how it is used. Users can review Synthesia's full privacy policy to understand retention periods and any available controls over this data collection.
