Deepin is a Chinese Linux operating system with its own Deepin Desktop Environment (DDE), developed by Deepin Technology in Wuhan. It is offered as an installation image for computers, and its desktop applications are built on the company's own DTK toolkit. The source code is published on GitHub and is mainly licensed under the GPL; the distribution also includes some proprietary programs, such as Google Chrome and Spotify.
Deepin Technology is a wholly owned subsidiary of UnionTech and is based in China. The operating system is therefore under Chinese corporate control and Chinese jurisdiction. The official pages do not say where user services are hosted. For a European organisation the open-source core allows inspection, but the development process and corporate structure sit outside the European legal framework. Use in a sensitive environment calls for an independent assessment, including of how updates are delivered and where packages come from.
