Client–server application designed to improve family safety and coordination through real-time location sharing and emergency alerts.
The system allows family members to stay connected, track locations and receive instant notifications in case of emergencies.
- C – core implementation
- TCP sockets – reliable client–server communication
- select() – server-side concurrency for multiple clients
- SQL database – persistent storage of users and families
- raylib + Dear ImGui – graphical user interface
The system follows a centralized client–server architecture.
- The server manages connections, validates requests and synchronizes data between users.
- The clients handle only the graphical interface and send commands to the server.
All important data such as:
- user accounts
- family groups
- location history
is stored in a relational SQL database to ensure persistence.
- user registration and authentication
- creation and management of family groups
- real-time location sharing
- SOS emergency alerts
- multiple notification types
- automatic alerts when entering or leaving predefined locations
- ability to belong to multiple families
- graphical interface for easy interaction
The graphical interface is implemented using raylib and Dear ImGui, providing an intuitive interaction model.
Main components include:
- login and registration window
- family management interface
- real-time location display
- settings and notifications panel
This project focuses on understanding and implementing:
- network programming using TCP sockets
- handling multiple clients with select()
- client–server architecture
- database integration
- GUI development
