This paper introduces a model for secure, private communication through push notifications without collecting sensitive user data. The model uses Google Firebase Cloud Messaging (FCM) to process push tokens, ensuring real-time message delivery with a 100% success rate. Experiments highlighted limitations in enabling direct replies within web notifications, which impacted real-time two-way communication. This research offers a viable solution to modern communication challenges, addressing privacy concerns and improving engagement without relying on traditional data-collection methods.
