Understanding HIPAA and Saudi data privacy laws is essential for effective telemedicine app design. These regulations require strict data protection, secure user authentication, and clear patient consent mechanisms. A well-structured telemedicine app design must prioritize privacy, encryption, and compliance from the ground up to safeguard sensitive health information. By aligning with both HIPAA and Saudi PDPL, developers ensure user trust, legal safety, and seamless healthcare service delivery in the digital era.
