By using proeliumartifex.com or any tool we publish on it, including the Stellaris Mod Builder, you agree to these Terms of Use. If you don't agree, please don't use the site or tools.
The site is informational and promotional for our two practices — a software studio (project delivery, solution design, consultancy, AI & automation) and a gaming practice (modding, tools, world-building) — and hosts free, browser-based tools for the modding community, including the Stellaris Mod Builder.
You're welcome to use the site and our published tools for personal, non-commercial and community purposes. Please don't scrape, reverse-engineer, or attempt to disrupt the site itself. Source code we publish on GitHub is governed by the license attached to that specific repository, which may permit broader use — check the repository in question.
Our tools run entirely in your browser and store your project data locally on your device using browser storage (see our Cookie Policy). We do not receive, store, or back up your project data — you are solely responsible for exporting and backing up anything you don't want to lose, including before clearing browser data, switching browsers or devices, or updating to a new version of a tool. Tools are provided "as is" with no guarantee of compatibility with future game patches, mod formats, or platform changes.
Stellaris and related marks are trademarks of Paradox Interactive AB. Proelium Artifex is an independent modding project and is not affiliated with, endorsed by, or sponsored by Paradox Interactive. Other product and platform names referenced on this site (GitHub, Nexus Mods, YouTube, Patreon, Ko-fi, etc.) belong to their respective owners.
The Proelium Artifex name, branding, and site content are owned by us unless otherwise noted. Mods and tools we publish for community use are governed by the license stated in their respective listing or repository.
Links to GitHub, Nexus Mods, YouTube, Patreon, Ko-fi and similar platforms are provided for convenience. We aren't responsible for their content, availability, or practices, including how they handle payments or your data — check their own terms and privacy policies.
The site and tools are provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, uptime, or fitness for a particular purpose.
To the fullest extent permitted by law, Proelium Artifex is not liable for any indirect, incidental, or consequential damages arising from your use of the site or tools, including loss of locally-stored project data.
We may update these terms from time to time; the "Last updated" date above reflects the most recent revision. Continued use of the site after changes means you accept the updated terms.
These Terms, and any dispute arising from them or from your use of the site or tools, are governed by the laws of England and Wales, and are subject to the exclusive jurisdiction of the courts of England and Wales.
