Nonprofit organizations are constantly challenged to find new ways of finding new donors and sources of funding for their solidarity actions. The traumatic events that occurred in the summer of 2017 in Portugal that caused more than 100 deaths consumed by the fires caused these organizations to have difficulties in coordinating the whole wave of solidarity generated in the community. In this sense, this study has developed a technological platform based exclusively on free technologies that allowed these entities to receive donations and manage this whole process. The application developed enables the reception of anonymous donations and monitoring the status of each donation. Furthermore, several requirements in terms of compatibility with mobile devices, usability, security, and privacy were implemented in the platform.
