Licences and attribution

Not reviewed by a lawyer. Not legal advice. The facts on this page were taken from the MimOS repository on 4 August 2026, not from a template.

Last updated: 8 September 2026. Release described: 1.0.

Three layers, three different situations

A MimOS image is not one work with one licence. It is around a thousand pieces from different places, and they should not be confused.

1. What we write ourselves — MIT

Twelve packages, all under the MIT licence, copyright © 2026 David Fontanet Bujaldón:

Package What it is
mimos-actualizador Update notifier and its tray icon
mimos-branding Palette, themes, wallpaper, system identity
mimos-calamares-config Installer configuration
mimos-grub-theme Boot menu theme
mimos-installer Installer launcher
mimos-keyring Package signing public key
mimos-live-environment Live session artefacts
mimos-plasma-theme The MimOS Claro and MimOS Oscuro global themes
mimos-plymouth-theme Boot splash
mimos-release System identity and update channel
mimos-welcome Centro de MimOS, the Store and the mimos-diagnostico tool
mimos-welcome-live The Live session’s Centro de MimOS

You may use, copy, modify and redistribute them, including commercially, keeping the copyright notice. The full text accompanies the repository.

2. Third-party software we modify — GPL

Calamares 3.4.2, the installer, is distributed under GPL-3.0-or-later, and in MimOS it carries our patches: accessibility fixes on the credentials page, password redaction in the logs, and layout changes for scaled displays.

That means MimOS distributes a modified GPL binary, which brings with it the obligation to make the corresponding source available.

That obligation has been met in public since 3 August 2026: the complete build recipes and patches for every package on the channel — Calamares included — live at https://github.com/DavidFB-creator/mimos-packages, tagged with the exact commit each published version was built from.

3. Everything else — its own licences

Around a thousand further packages come unmodified from the official Arch Linux repositories: the Linux kernel, KDE Plasma, systemd, Mesa, PipeWire and the rest of the system. Each keeps its own licence — GPL, LGPL, MIT, BSD, Apache and others.

Our MIT licence applies to none of it. To see any installed package’s licence:

pacman -Qi package-name

Typefaces

The typefaces shipped with the image are distributed under the SIL Open Font License 1.1:

  • Inter, used in the brand and the installer.
  • Noto and Noto Emoji, general system coverage.

Baloo 2, the brand typeface, is packaged in the repository so the logos can be regenerated, but is not included in the image: the logos are exported with their glyphs converted to outlines, so they do not depend on the font being installed.

Images published on this site

All images are served from this domain. Their provenance is recorded in the repository’s asset catalogue:

  • logos, MIMI, wallpapers and visual identity are original MimOS/XI14 assets and are not licensed by the code’s MIT licence;
  • screenshots document specific MimOS images and were made by the team. Third-party software, names and marks visible in them retain their holders and licences.

The site uses no stock photography, generated images presented as the product, or screenshots copied from third-party reviews. WebP files are conversions of the same originals.

How to obtain the source

Written offer. If you have received a MimOS image and want the source corresponding to any of its components under the GPL or another licence requiring it, write to support@mimoslinux.org and we will provide it, by any reasonable means and at no more than the cost of delivery. This offer is valid for three years from the publication of the release concerned.

In practice there are three routes, most direct first:

  1. Unmodified packages: their source is in Arch Linux’s public infrastructure, which is where we took them from.
  2. Calamares, which we do modify: complete recipes and patches, published at https://github.com/DavidFB-creator/mimos-packages.
  3. Anything you cannot get by the first two: the written offer.

The brand is not in the licence

The MIT licence covers the code, not the identity. The names MimOS, MIMI and XI14, the MIMI character, the logos and the visual system are not licensed alongside the code.

You may name them and use them to refer to the project. You may not use them to identify a derivative distribution. Deriving is allowed; doing it under our name is not. Details in the Terms of service.
