The application allows you to conduct confidential correspondence without fear that its contents will become available to third parties. This became possible due to the complete encryption of data on the device side (before sending it to the network) - both text messages and attached files are encrypted. Also, a characteristic difference is the complete absence of advertising and intrusive recommendations (friends, news, etc.), there is no questionable content. To use the application, it is enough to specify only a username and password, then log in or register - no more data is required.At the moment, the following functionality is available:- profile management (filling in data about yourself and uploading a photo);- search for new interlocutors;- sending text messages and files;- obtaining information about the status of the interlocutor (online or his last time on the network);- check for new messages and show notifications in the status bar;- blocking the interlocutor, sending complaints;- deleting dialogs (deleted from the one who requested deletion, messages remain from the other interlocutor);- various settings (for example, changing the server address and specifying the frequency of checking for new messages);- other functionality that is added as the application improves.
