DE-Alarm is a specialized alerting application designed for authorities and organizations involved in security tasks. It serves as a modern complement to traditional pager systems, providing real-time notifications to emergency responders about ongoing incidents from their respective control centers. The app features an intuitive interface that allows users to access critical information about each incident, prepare for response, and confirm their participation. Registration is exclusively available to personnel from response organizations using a personal code, ensuring compliance with data protection regulations.

The app transmits alerts as push notifications to registered emergency personnel's smartphones, delivering both textual and visual details about the incident, including address maps, incident type, severity, involved parties, and timestamps. Users can confirm their response to an incident through a dedicated button, allowing control centers to track participation. DE-Alarm prioritizes data privacy with end-to-end encryption and local storage of personal data on individual devices, and it supports multiple profiles for shared devices, enhancing its usability across different organizations.
