Mageloom FX: End User Licence Agreement

Created: 2026-11-10 · Last updated: 2026-11-11

Version 1.0, effective 11 November 2026.

This agreement is between you and Anargyros Gkogkidis, a sole trader (atomiki epixeirisi) in Greece, operating under the name Extalia ("we", "us"). VAT number: EL158346649. Business address: Palaion Patron Germanou 6, 60300 Aiginio, Greece. Contact: [email protected]. Website: mageloomfx.com.

By installing or using Mageloom FX, you agree to this agreement. If you do not agree, do not buy, install or use it. This agreement is linked from the store page before you buy.

1. Words used here

• App: Mageloom FX, the desktop application, its command line tool (fx or mageloom), its MCP server, its documentation and its updates.
• Built-in Content: the presets, recipes, shapes, materials, figures, example effects, templates and other content that come with the App.
• Output: what you make with the App: rendered images, sprite sheets, animations, videos, Godot scenes and resources, other engine exports, and recipe files you create or change.
• Runtime Files: the scripts, shaders and support files the App writes into an export so the Output works in a game engine.
• Standalone Pack: see section 4.

2. Licence to use the App

The App is licensed, not sold. When you buy it, we give you a personal, non-exclusive, non-transferable, worldwide licence to install and use the App, for personal and commercial purposes, under this agreement.

• Per user. The licence is for one person. You may install the App on computers you own or control and use yourself (for example a desktop and a laptop), on every operating system it is released for (macOS, Windows and Linux). Only you may use it. The App has no licence key or activation.
• Companies and teams. A company may buy one licence for each person who uses the App. Each licence is assigned to one named person at a time. The company may reassign a licence to another person, for example when staff change, and the previous person then stops using it.
• Store terms. If you bought the App on Steam or itch.io, that store's terms also apply to the purchase and to how the App is delivered. If they conflict with this agreement about the purchase, the store's terms win. This agreement governs your use of the App and your Output.

3. Your Output is yours

• You own your Output. We claim no ownership of it.
• To the extent we hold any rights in your Output, we transfer them to you, except the rights in Built-in Content that appears in it. For that Built-in Content, we give you a perpetual, irrevocable, worldwide, royalty-free licence to use it as part of your Output, under sections 3 and 4.
• You may use your Output, including the Runtime Files, royalty-free in games, apps, mods, videos, trailers, films, websites, teaching material, client work and any other project, commercial included.
• You do not need to credit Mageloom FX. A credit such as "Effects made with Mageloom FX" is appreciated, never required.
• This section continues after the agreement ends, for Output you have already made (section 12).

4. The one limit on Output: no Standalone Packs

You may not sell, license, give away or otherwise distribute Output as a Standalone Pack.

A Standalone Pack is a collection of Output, distributed free or paid, where the Output itself is the main thing offered, for other people to use in their own projects. Examples:

• "50 spells made with Mageloom FX" sold or given away on an asset store, a marketplace, itch.io, a website or a Patreon.
• A library, bundle or subscription of effects, sprite sheets, textures or Godot effect scenes.
• A tool or service that hands out Output for others to use.

These are not Standalone Packs and are allowed:

• Your games and apps, released in any form, even if a player could extract the files.
• Mods for any game, and open source projects whose source files include Output.
• Client work. Making Output for a client who uses it in their project. The client may use it under the same terms as you.
• Portfolios and sharing. Showing Output in portfolios, showreels, social media, devlogs, tutorials and forum posts, including the source files so others can learn or reproduce your work, as long as you do not offer them as a reusable effects collection.
• Your team. Sharing Output with people working with you on the same project.
• Your own recipes. Sharing recipe files you made with other Mageloom FX users, free or paid. Recipe files need the App to be used, so they are not a Standalone Pack, but this does not allow selling the Built-in Content (below).

You also may not sell, give away or publish the Built-in Content as-is or with trivial changes, on its own or as part of a pack, for example by exporting every built-in preset and offering the set.

If you are unsure whether something is a Standalone Pack, email [email protected] and we will answer.

5. What you may not do with the App

Except where the law allows it and this cannot be restricted, you may not:

• copy, share, rent, lend, sell or sublicense the App, or let others use your licence;
• reverse engineer, decompile or disassemble the App;
• remove or change copyright notices, or bypass any licence check;
• run the App, its command line tool or its MCP server as a service that other people use (for example a hosted effects generator);
• use the App to break the law or anyone's rights.

6. AI agents and automation

You may use the App through its command line tool (fx or mageloom) and its MCP server, including through AI agents, scripts and build pipelines.

• Use by an agent, script or pipeline that you run or control counts as your own use under your licence.
• You are responsible for what your agents do with the App and with Output, as if you had done it yourself.
• An agent working for someone else, or open to the public, is use by others and needs their own licence (section 5).

7. Share with Mageloom FX

The App never uploads your work on its own. It uploads only when you press Share with Mageloom FX and confirm.

Each time you share, you choose:

1. Show it (unticked by default). If you tick it, you give us a non-exclusive, worldwide, royalty-free licence to show that submission in the Mageloom FX gallery, on our website and stores, and in our marketing, credited with the name you choose (or uncredited if you choose).
2. Use it to improve the App (separate, unticked by default). If you tick it, you also allow us to use that submission to improve the App's generators, including to tune, test or train them.

• You keep ownership of everything you share.
• Before upload, the App removes file paths and personal names from the recipe.
• You confirm you have the right to share the submission.
• Withdrawal. You can withdraw a submission at any time by email to [email protected] or with the delete link the App keeps for it. We then remove it from the gallery and stop any new use within 30 days. Marketing already printed or published, and improvements already made to the generators, cannot be undone.

8. Privacy

The App has no telemetry or analytics and works offline. Crash reports and bug reports are sent only if you click Send. See the Privacy Policy.

9. Third-party software

The App includes open source software and fonts under their own licences, listed in Third-Party Notices. Those licences apply to those parts and are not limited by this agreement.

10. Updates

• We may release updates that fix, add, change or remove features.
• If you are a consumer, we will provide the updates needed to keep the App working as described, for the period the law requires, and we will not change it in a way that harms you without the notice and rights the law gives you.
• Some updates may be needed to keep using online features such as sharing.
• Your purchase includes every update we release for versions 0.x and 1.x of the App, on every operating system it supports.

11. Warranty and liability

• If you are a consumer in the EU or the UK, you have legal rights if the App does not work as described. Nothing in this agreement removes or limits them.
• Beyond those rights, and to the extent the law allows, the App is provided "as is", without other warranties, and we do not promise it will be error-free or suit every purpose.
• To the extent the law allows, our total liability under this agreement is limited to the price you paid for the App, and we are not liable for indirect losses, lost profit, or lost data. Back up your work.
• We do not limit liability for death or personal injury caused by our negligence, for fraud, intent or gross negligence, or for anything else that cannot be limited by law.

12. Ending this agreement

• You may stop using the App and delete it at any time.
• If you seriously breach this agreement and do not fix the breach within 14 days of our notice (or at once if it cannot be fixed), we may end your licence. You must then stop using and delete the App.
• When the agreement ends, your rights in Output you already made (section 3), its limit (section 4), and sections 7 (for past submissions), 11, 12 and 14 continue.

13. Refunds and consumer rights

• No refund once downloaded. Mageloom FX is digital content supplied by immediate download. By buying, you agree that the download is available at once and you acknowledge that you then lose the 14-day right of withdrawal (EU Directive 2011/83/EU, Art. 16(m)). The store page says this before you buy. Please try the free web demo at demo.mageloomfx.com first.
• If it does not work. If the App does not run on your computer and we cannot fix it, email [email protected] within 14 days of buying and we refund you. Your rights if the App is faulty (section 11) are not affected.
• On Steam, Steam's refund policy also applies.
• Nothing in this agreement waives rights you have as a consumer that cannot be waived.

14. Law and courts

• Greek law governs this agreement. If you are a consumer living in another country, you keep the protection of the mandatory laws of your country.
• If you are a consumer in the EU, you may bring a claim in the courts of your country of residence, and we may only sue you there. Otherwise, the courts of Thessaloniki, Greece, have jurisdiction.
• If you are a consumer, you may also turn to the Hellenic Consumer's Ombudsman (www.synigoroskatanaloti.gr) or the consumer body of your country.

15. General

• If a part of this agreement is invalid, the rest still applies.
• We may change this agreement for future versions of the App. Changes apply to you only when you accept them, for example when installing an update, and never take away rights in Output you already made.
• You may not transfer this licence without our written consent, except where the store allows it. We may transfer this agreement to a buyer of the App, with your rights unchanged.
• This agreement is written in English.
