Abstract	In today’s digital era, communication through chat applications has become an integral part of everyday life. However, the increasing number of cyber threats and data breaches raises serious concerns about user privacy and message confidentiality. This research focuses on developing a secure chat application that provides end-to-end encryption to ensure that only the sender and receiver can read the messages. The proposed system is implemented using Android Studio, Firebase, and the AES encryption algorithm. The encryption process secures all messages before they are transmitted, preventing unauthorized access even if the database is compromised. The application also integrates Firebase Authentication for user login and real-time messaging using Firebase Realtime Database. The results show that the proposed model provides secure, fast, and reliable communication while maintaining data privacy and user confidentiality.
