Lecturio is an online e-learning platform for medical and health education. It offers video lectures, study material and exam preparation for students of medicine, premedical programmes and nursing, and is also available as a mobile app. The service is commercial and is delivered online and through apps. The pages consulted do not describe the software as open source and do not mention a self-hosted variant.
Lecturio GmbH is a German company, and its App Store listing gives its address as Leipzig, Germany. The pages consulted do not name the owners of the company, so ownership cannot be assessed from them. They also do not state where customer data is hosted, and no GDPR or data processing statement was found in the pages reviewed. A European organisation should check the privacy terms, the hosting location and any sub-processors in other countries, and make sure a data processing agreement is in place before use.
