Plasma Mobile is an open-source shell for Linux smartphones and tablets, built on the technology of the KDE Plasma desktop. It provides a home screen, status bar, task panel, lock screen and settings, designed for touch use on mobile hardware. It is an alternative to the interface of Android and iOS. The software is installed on a Linux system on a supported device and is not offered as a hosted service.
The project is developed by the KDE community, and legal and financial matters are handled by KDE e.V., an association with its address in Berlin, Germany. The source code is published under GPL-2.0-or-later and LGPL-2.1-or-later, so an organisation can inspect, build and modify it on its own infrastructure. Because no vendor runs a cloud service around the shell, no foreign provider holds user data through it. A European organisation should mainly check which distribution and device image it uses and who maintains that image.
