End User Licence Agreement

Version 1.1 · effective 18 September 2026

This End User Licence Agreement (the “Licence”) is a binding agreement between you and the developer of Modsmith, publicly known as Arane (“Modsmith”, “we”, “us”). It covers builds of Modsmith supplied with this Licence, including updates, portable builds and any documentation that comes with it (the “Software”). The Terms of Service apply to the Software as well; where the two differ about the Software, this Licence prevails.

Release status. The application is in development and no public build is available here yet. This Licence applies when supplied with a build and accepted as required by law; it does not retroactively replace a different licence already supplied with a build.

By installing, copying or using a build supplied with this Licence, you accept it to the extent permitted by applicable law. If you do not accept it, do not install or use the Software.

1. Licence grant

1.1. Subject to this Licence, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the Software, in object code form, on computers that you own or control, for the purpose of managing modifications to games that you have the right to modify.

1.2. Mod-management features, including Nexus integration and local checks, are free. Optional cloud AI services are planned under separate subscription terms and are not live; this Licence does not itself activate them.

1.3. The Software is licensed, not sold. We retain all right, title and interest in it. All rights not expressly granted are reserved.

1.4. The Software is commercial computer software developed at private expense. If you acquire it for or on behalf of a government, you receive only the rights granted to every other licensee under this Licence.

2. Restrictions

Except to the extent the law expressly permits it regardless of this Licence, you may not:

  • copy the Software except as necessary to install and use it and to keep one backup copy;
  • distribute, publish, sell, rent, lease, lend, sublicense or otherwise make the Software available to anyone else;
  • decompile, disassemble, reverse engineer, or otherwise attempt to derive the source code, algorithms or internal workings of the Software;
  • modify, adapt, translate or create derivative works of the Software;
  • remove, obscure or alter any proprietary notice, licence text or third-party notice in the Software;
  • circumvent licence checks, quotas or security controls, except through documented controls intended for that purpose or where applicable law permits it;
  • use the Software’s code, assets or internal workings to develop a competing product, or use any part of the Software in another product;
  • use the Software for anything unlawful or in violation of a third party’s rights or terms, including the terms of your game and of Nexus Mods.

3. Updates

3.1. Updates may add, change or remove features and be supplied under this Licence or a new licence presented with the update. We may require a supported build for an online service. Installation remains your choice; declining an update may prevent access to that service.

3.2. We may stop supporting or distributing older builds at any time.

3.3. Builds marked early access, alpha, beta, preview or pre-release may be incomplete, may change data formats, may stop working, may be withdrawn at any time, and carry no promise that a final release will follow.

4. Third-party components

The Software includes components licensed from third parties, including open-source components. They are listed in the third-party notices shipped with the Software and available from the About window, and the full licence texts are installed alongside the Software. Those licences govern those components. Nothing in this Licence restricts rights you have under an open-source licence to the component it covers.

5. Your game, your mods, your files

5.1. The Software works with your game installation, with mods created by other people, with files created by other tools, and with your saves and settings. None of these are ours. Mods remain the property of their authors and are governed by the terms of the site you obtained them from. You are responsible for having the right to use, modify and combine any content you install, and for complying with the terms of your game and of any service you connect.

5.2. The Software modifies your game installation in the way it describes: it links or copies mod files into the game folder, backs up the originals it replaces, records its steps in a journal and can reverse them. It also writes to game configuration files and to plugin headers when you ask it to, after keeping a backup. These safeguards are built with care, but they do not replace your own backups, and they cannot protect against changes made by other programs, by the game itself, or by you outside the Software.

5.3. Keep your own copies of saves and of anything you cannot afford to lose. Use the Software first on a game installation you can afford to reinstall.

5.4. We claim no ownership of your mods, game files, saves or configuration. This Licence grants no general right to upload, delete or withhold them. Requests you choose to submit to a future service are covered by that service’s disclosed processing terms.

6. Assistant features

6.1. Cloud AI features are planned and are not publicly available. Before activation, the relevant request data, recipients and controls must be disclosed. This Licence alone is not consent to send a request.

6.2. A model’s answer is a proposal. The Software validates it and applies it only when you choose to, through the same commands and with the same backups as any other operation. The model does not write to your files.

6.3. Model output may be wrong. You are responsible for reviewing a proposal before applying it and for the results of applying it.

7. Data

What the Software stores on your computer and what it sends over the network is described in the Privacy Policy. Network features, such as downloads and update checks, contact their respective services. Accepting this Licence is not consent to undisclosed AI processing or advertising.

8. Feedback

If you send us feedback, ideas or suggestions about the Software, you grant us, to the extent permitted by the law of your country, a perpetual, irrevocable, worldwide, royalty-free, sublicensable licence to use them for any purpose without payment or attribution, excluding unrelated personal data, confidential material and third-party files.

9. Term and termination

9.1. This Licence applies from the moment you install or use the Software and continues until ended.

9.2. You may end it at any time by uninstalling the Software and destroying any copies.

9.3. We may end this Licence for material breach not cured within 14 days after notice where cure is reasonable, or immediately for fraud, unlawful use or a credible security risk. Discontinuation or termination for convenience follows the notice and refund protections in the Terms of Service.

9.4. After termination, stop general use and uninstall the Software. Limited local use solely to recover your own data or undo existing deployments is permitted where lawful and technically available. Keep backups until that work is complete. Sections 1.3, 2, 5, 8, 10, 11, 12, 13 and 14 survive as applicable.

10. Disclaimer of warranties

To the fullest extent permitted by law, the Software is provided “as is” and “as available”, with all faults and without warranty or condition of any kind, express, implied or statutory, including any warranty of merchantability, satisfactory quality, fitness for a particular purpose, title, non-infringement, or that the Software will be uninterrupted, error-free, compatible with your system, your game or any mod, or safe for your data. Some jurisdictions do not allow the exclusion of implied warranties; in that case the exclusion applies to the extent permitted.

11. Limitation of liability

11.1. To the fullest extent permitted by law, we and our licensors are not liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of data, saves, game installations, mods, profits, revenue or goodwill, arising from or related to the Software or this Licence, however caused and under any theory of liability, even if advised of the possibility of such damages.

11.2. To the fullest extent permitted by law, our total aggregate liability arising from or related to the Software or this Licence is limited to the greater of the amount you paid for the Services, through the payment partner, in the twelve months before the event giving rise to the claim and twenty US dollars.

11.3. Nothing in this Licence excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, for gross negligence or wilful misconduct, for fraud, or for non-waivable consumer rights.

12. Export and sanctions

Comply with export controls and sanctions legally applicable to your use or distribution of the Software. Access may be restricted where required by applicable law or provider obligations.

13. Governing law and disputes

Applicable law determines the governing law and competent courts, as described in section 20 of the Terms of Service. Mandatory consumer protections and access to legally available remedies remain unaffected.

14. General

14.1. We may assign this Licence to an affiliate or successor, subject to law and without reducing existing rights. You may not assign it without consent except where the law permits.

14.2. If a provision of this Licence is unenforceable, it is enforced to the maximum extent permitted and the rest remains in force. Our failure to enforce a provision is not a waiver.

14.3. This Licence is written in English. English prevails over a convenience translation only where permitted by law.

14.4. We may update this Licence for future builds. The version that applies to a build is the one shipped with it and shown in its About window; the current version is always published on the Website.
