The document discusses several key issues regarding mobile apps and data protection obligations: - Mobile apps have become widely used for various purposes beyond basic productivity and now have access to large amounts of user data stored on devices. - The involvement of multiple players in app development and distribution like app stores, developers, and device manufacturers complicates transparency for users. - Both the Consumer Rights Directive and General Data Protection Regulation impose informational and consent requirements on app traders and developers to protect users, but space limitations on mobile devices make comprehensive disclosures challenging. Short-form, layered notices with icons are proposed to help address this issue.
