"Hudhud" is a secure local messaging application designed for instant and secure communication between users within a specific community, such as a company, university, or residential neighborhood, without relying entirely on the public internet. The application connects to the organization's local server via a fixed port, automatically assigning the application a specific identity and information specific to the company. The application is characterized by its ability to provide a closed and secure communication environment, with an easy-to-use interface and a powerful set of features that support privacy and practical functions such as text and voice chats, file sharing, account management, and message control.
