Gnumeric is an open-source spreadsheet program from the GNOME project. It is intended for calculations, data tables and analysis, and is offered as a free download under the GNU General Public License, version 2 or 3. The program runs locally on the user's own computer, so spreadsheets are not processed on a vendor cloud. It is positioned as an alternative to Microsoft Excel for organisations that want spreadsheet software without a licence fee.
Gnumeric is developed by volunteers within the GNOME Project, which is backed by the non-profit GNOME Foundation. The foundation is a US non-profit organisation (501(c)(3)) with its seat in Orinda, California, so the body behind the project falls under US law. The source code is public, so organisations can inspect, build and modify the program themselves. The project website describes a downloadable program rather than a hosted service, so documents can stay on the organisation's own infrastructure.
