What is threema-tray.exe?
threema-tray.exe is the lightweight background component that powers the Threema Desktop tray icon and quick actions. It stays resident in the system tray, handles notifications, previews, and chat shortcuts, and coordinates with the main Threema window for a fast, unobtrusive experience.
Runs as a small background service that communicates with threema-desktop.exe via IPC to sync messages and status updates while keeping memory usage low. The tray process updates icons and handles user input for rapid replies without loading the full UI.
Quick Fact: Threema Tray is designed to stay lightweight, prioritizing fast access to chats and notifications with minimal impact on system resources.
