鹿久久 is a multimedia app that focuses on image-based communication, allowing users to freely create school class spaces and groups for family and friends. It offers secure, permanent cloud storage for original images and allows for personalized printing of creative products.

The app features two main scene modes: school class spaces and personal spaces. Users can easily switch between various spaces to enhance their virtual social life. In school class spaces, parents are invited to share and download students' life, group, and activity photos securely. In personal spaces, users can invite family and friends to share a plethora of original images and videos, enabling comments and likes.
