휴넷 사회복지평생교육원 is a free application developed by HUNET, an education and reference platform on Android. This app allows users to easily access and learn from courses they have enrolled in using their smartphones. With the ability to stream and download DRM-protected content, users can conveniently study anytime and anywhere.

Upon logging in with their credentials, users can access course materials and track their progress. The mobile learning progress is synchronized with the actual course progress and study time, making it easy for users to stay on top of their studies.

The app requests optional access permissions for storage and calendar. The storage permission is used to transfer and save photos, videos, and files on the device, while the calendar permission is necessary for modifying and displaying schedules on the device's calendar.

Please note that the app can still be used without granting these optional access permissions. The app's access permissions are designed to comply with Android 6.0 and above, with essential and optional permissions implemented separately. For users with Android versions below 6.0, it may not be possible to individually allow optional permissions. It is recommended to check if the device manufacturer provides operating system upgrade functionality and consider updating to Android 6.0 or above if available.
