A Mobile Secure Content Development Application for Children in the Software Development Life Cycle Framework

This study deals with the software development process of a mobile application that will support children's learning, development and entertainment processes while ensuring their safety in the online environment. The project was carried out within the framework of the Software Development Life Cycle (SDLC) and adopted a systematic approach including requirements analysis, design, development, testing and maintenance phases. The application aims to provide appropriate content for children by minimizing digital security risks and to enable parents to safely control their children's internet use. With the Extreme Programming (XP) methodology, a continuous improvement process based on user feedback was implemented and security and performance tests were successfully completed. The article shows that not only coding but also effective management of the whole process in software development projects contributes to project success. The study is expected to contribute to the literature on children's digital safety and provide a basis for future research in this field.
