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.
