Melty Terms of Service

Last updated: October 14, 2026

These Terms of Service ("Terms") are a legal agreement between you and Stella Montis Inc. ("Stella Montis," "Melty," "we," "us," or "our"). They cover your use of Melty, including the website at melty.gg, the Melty desktop app, the tools Melty offers creators and their coding agents, and everything else we provide under the Melty name (together, the "Services").

By using the Services, creating an account, installing the Melty app, or publishing a mashup, you agree to these Terms. If you don't agree, don't use the Services and uninstall the Melty app.

1. What Melty is

Melty is a place to find, play and share mashups and mods for PC games. A "mashup" is a mod, a combination of games, or another change to a game that a creator publishes on Melty.

When you press Play, the Melty app sets up what the mashup needs on your PC and starts it. Creators publish mashups from the website, from their own coding agents through Melty's tools, or from a GitHub repository.

We may add, change, limit or stop any part of the Services at any time.

2. Who can use Melty

If you're under the age of majority where you live, you may use Melty only with a parent's or legal guardian's permission, and they are responsible for your use. You may not use Melty if the law, sanctions rules or a previous suspension by Melty bars you from doing so.

If you use Melty for a company or other organisation, you confirm that you can bind it to these Terms, and "you" includes it.

3. Your account

Some features need an account. Keep your sign-in details, and any tokens Melty gives you or your coding agent, private. You're responsible for what happens under your account, including what a coding agent publishes with your token. Tell us promptly if you think your account or a token has been compromised.

Your profile name and picture, what you're playing, and the mashups you publish can be seen by other people on Melty.

4. The Melty app on your PC

To play a mashup, the Melty app does things on your PC on your behalf. You agree to let it:

  • find the games installed on your PC and read their versions, so it can tell what you can play;
  • download the mashup's files and the tools it needs, such as mod loaders, launchers and build tools, from Melty or from the original authors' sources;
  • write files into your game folders and other folders a mashup needs, after keeping a copy of any file it replaces so it can put your game back as it was when you remove the mashup;
  • build parts a mashup needs on your PC, using tools it downloads into its own folder;
  • when a mashup is made to use your own copy of a game, look for that copy in your folders and drives and copy the files it needs into the mashup's folder;
  • start your games, the mashup's own programs and any setup step it needs; and
  • update itself automatically.

Every mod and mashup is audited before it's released on Melty (see section 6).

Some games' rules, anti-cheat or online services don't allow mods, so play mashups within each game's rules. It's always a good idea to keep backups of saves you care about.

You may install and use the Melty app for your own use under these Terms. Don't copy, sell or redistribute it, or get around its security, except where the law allows.

5. Your games

Mashups run on games you own. Melty doesn't sell, lend or license any game. You need your own legitimate copy of every game a mashup uses, and your own accounts for the services those games need (for example Steam or a Minecraft account). Your use of a game stays subject to its publisher's and store's terms, and Melty doesn't change your obligations to them.

6. Every release is audited

Every mod and mashup uploaded to Melty is audited before it's released on Melty. The audit reads every file in the release, and its source code when it's published from GitHub. A release also has to run successfully on its creator's PC first. Only releases that pass the audit go live, and every update is audited again before players get it.

Anyone can report a mashup from its page, and we'll review it.

7. Publishing mashups

You're responsible for everything you publish. That includes every file in a mashup, game files included, its name, pictures and description, and every release published under it, whether you publish it yourself, through a coding agent, or automatically from a GitHub repository you connected. Only publish what you have the right to share.

By publishing, you confirm that you have every right, licence and permission needed to share the mashup, and to let Melty and players use it as these Terms describe, and that it doesn't break any law or anyone else's rights.

You keep ownership. You keep whatever rights you have in what you publish. In these Terms, "your Content" means a mashup you publish on Melty and everything you publish with it: its files and releases, its install and setup instructions, and its name, pictures, videos and description.

Melty is the only marketplace for your Content. By publishing on Melty, you give Melty an exclusive, worldwide, royalty-free licence, which Melty may sublicense, to copy, distribute, make available, adapt and promote your Content, and any version based on it, through any marketplace, mod or game-content hosting site, launcher, app store or similar service that offers mods, mashups or game content to the public (a "Marketplace"). Exclusive means that, while it lasts, nobody, including you, may publish, upload, distribute or license your Content, or any version based on it (a modified, partial, renamed or ported version, or a remix), on or to any Marketplace other than Melty, or let anyone else do so, without Melty's written permission. You may still keep your source code in your own repository (for example on GitHub), and show your mashup in screenshots, videos and posts on your own website and social channels, with a link to Melty.

How long it lasts. The exclusive licence lasts while your Content is available on Melty and for 12 months after you take it off Melty. If your mashup was already on Melty before October 14, 2026, it starts on November 13, 2026, unless you take the mashup off Melty before then. If you shared your Content on another Marketplace before you first published it on Melty, it may stay there as it is, but new versions and releases follow this section.

Melty's other rights to your Content. You also give Melty a worldwide, non-exclusive, royalty-free licence to host, store, copy, process, test, show, distribute and promote your Content, and to set it up and run it on players' PCs, as needed to operate and improve the Services. This lasts while your Content is on Melty, and for as long as needed afterwards for backups, records, disputes and legal obligations.

Other people's parts. The exclusive licence covers what you made and your mashup as a whole. Parts made by others, such as games, other creators' mods, libraries and open-source code, stay under their owners' own terms. You confirm that you haven't given, and won't give, anyone rights in your Content that conflict with Melty's exclusive licence, for example by putting a licence on your own code or files that lets others distribute them on another Marketplace.

Melty can enforce it. Melty may enforce its rights in your Content in its own name, including by sending takedown notices and bringing claims against anyone who copies, uploads, offers or distributes your Content on another Marketplace. You also authorise Melty to act for you to protect your Content there, and you'll give reasonable help, such as confirming that you didn't upload or authorise a copy. Melty decides whether and how to enforce.

Licence to players. You let anyone who can reach your mashup on Melty download, install and play it for their own personal use, through Melty only. If you allow remixes, you also let other creators make their own versions based on yours to publish on Melty only, credited to yours.

Remixes stay on Melty. When you remix a mashup, or make any version based on a mashup or anything else you got through Melty, your version is your Content and follows this section, and the parts that come from the original stay under its creator's rights and Melty's exclusive licence. You may publish your version only on Melty. However much you changed it, you may not publish, upload, distribute or license it, or any modified, partial, renamed or ported version of it or of the original, on or to another Marketplace, or let anyone else do so, without the permission of Melty and the original's creator. This applies whether or not your version was ever published on Melty.

Going live. A release goes live once Melty has seen it running on your PC and it has been audited. We may keep a release from going live, or take it down, at any time.

Install reports. When players install or play your mashup, Melty records whether it worked, with short error details and the game version. You and your coding agent can see these reports to fix problems.

Coding agents. If you connect a coding agent to Melty, it acts for you. You're responsible for what it does with your account and token.

8. Playing together

Multiplayer mashups come with a join link. Anyone who has the link can join the game. If you make a game public, anyone on Melty can see it and join.

When you host a game, other players connect to your PC, either directly or through the game's own services. To make that work, Melty shares your game's network address (IP address and port) with the players who join that game. Melty doesn't run game servers, voice or chat.

You're responsible for how you behave in games and for who you invite. Hosts can remove players and anyone can block other players.

9. Things you may not do

You may not, or help anyone else to:

  • publish or share anything you don't have the right to share, or that infringes anyone's copyright, trademark, privacy or other rights;
  • publish malware, spyware, cryptominers, or anything built to harm players, their PCs, accounts or data, or to collect information without their knowledge;
  • hide what a mashup does, or misrepresent who made it or what games it needs;
  • publish anything illegal, sexually exploits minors, promotes violence or terrorism, or harasses, threatens or exposes another person;
  • use Melty to cheat in competitive online play against people who haven't agreed to it;
  • impersonate anyone, or abuse other players, including through multiplayer games or reports;
  • get around Melty's checks, limits, security or the publishing rules, or access anything you aren't allowed to;
  • disrupt, overload, scrape or attack the Services;
  • download, copy, extract or collect mashups, their files, Melty's packages, install instructions, listings or data in bulk, by automated means, or in any way other than through the Melty app as it's meant to be used;
  • upload, mirror, redistribute, sell or offer any mashup, a remix of one, any version based on one (modified, partial, renamed or ported), or anything else taken from a mashup or from Melty, on another Marketplace or service, or present a copy as published there by its creator, without the permission of its creator and Melty;
  • use mashups, Melty's packages, install instructions, listings or data to build, stock, supply or improve a competing service, or to train or improve AI models; or
  • sell, rent or give access to your account or tokens.

Anyone can report a mashup from its page. We may remove or disable any mashup, release or account that we believe breaks these Terms or the law, or puts players, Melty or others at risk, with or without notice.

Repeat infringers. If mashups you published are taken down for infringing others' rights more than a set number of times, you'll lose the ability to publish, and we may close your account.

Copyright notices. If you believe something on Melty infringes your copyright, send a notice to david@melty.gg. Include: the work you say is infringed; where it is on Melty (a link); your contact details; a statement that you believe in good faith the use isn't authorised by you, your agent or the law; a statement, under penalty of perjury, that your notice is accurate and that you're the owner or authorised to act for them; and your physical or electronic signature. We'll take down material we're notified about where appropriate and tell the creator.

Counter-notices. If your mashup was taken down and you believe that was a mistake, you may send a counter-notice to the same contact with the details the law requires. We may restore the material unless the person who complained tells us they've started legal action.

11. Paid features

Melty is free to use, and all mashups are currently free. If we introduce paid mashups, tips or creator payouts, additional terms will apply to them, and payments will be handled by a payment provider under its own terms.

12. Other services

Melty works with services run by others, such as Steam, Discord, Google sign-in, GitHub, game publishers, launchers, mod loaders and the sources Melty downloads tools from. Those services have their own terms and privacy policies, and Melty isn't responsible for them, including their availability, decisions or enforcement.

13. Melty's rights

Melty, the Melty app and website, their software, design and the Melty name and logos belong to Stella Montis or its licensors. These Terms don't give you any right to them except to use the Services as described here. Don't use Melty's name or logos in a way that suggests we made or endorse your work.

Melty's catalogue. What Melty makes to bring mashups to players also belongs to Stella Montis: the packages, builds and setup Melty prepares, Melty's compatibility, test, install and audit data, the screenshots and videos Melty captures, and Melty's listings, rankings and catalogue as a whole, including how they're selected and arranged. Install and setup instructions that you or your coding agent write are part of your Content (section 7). You may use the screenshots and videos Melty captures of your own mashup to promote it.

If you send us feedback or ideas, we may use them freely without owing you anything.

14. Privacy

Our Privacy Policy explains what information we collect and how we use it.

15. Ending your use

You can stop using Melty at any time and uninstall the app. We may suspend, limit or close your account, or take down what you published, if we believe you broke these Terms or the law, or to protect players, Melty or others.

When your use ends, your licence to use the Services ends. Sections that by their nature should last, including those on responsibility, Melty's exclusive licence for as long as section 7 says, licences already granted for removal and records, enforcement, disclaimers, liability, indemnity and disputes, continue to apply.

16. Disclaimers

The Services and all mashups are provided "as is" and "as available." To the fullest extent the law allows, Melty disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, title and non-infringement.

Melty doesn't promise that every mashup will work on every PC, that every game publisher or online service allows modded play, or that every multiplayer game will connect.

17. Limitation of liability

To the fullest extent the law allows, Stella Montis and its affiliates, officers, employees, contractors, licensors and service providers won't be liable for any indirect, incidental, special, consequential or punitive damages, or for lost data, saves, profits, goodwill, or game or account bans, arising from or relating to the Services or any mashup, even if we were told they were possible.

To the fullest extent the law allows, our total liability for all claims relating to the Services or these Terms won't be more than the greater of $100 or the amount you paid Melty in the 12 months before the claim arose.

Some places don't allow some of these limits, so they may not all apply to you.

18. Indemnity

To the fullest extent the law allows, you'll defend and indemnify Stella Montis and its affiliates, officers, employees, contractors, licensors and service providers against claims, losses and costs, including reasonable lawyers' fees, arising from what you publish, your use of the Services, your games and multiplayer sessions you host, or your breaking these Terms, the law or anyone's rights.

19. Changes to these Terms

We may update these Terms. If a change is significant, we'll tell you, for example on melty.gg, in the app or by email, and update the date at the top. If you keep using Melty after a change takes effect, you accept the updated Terms.

20. Governing law and disputes

These Terms are governed by the laws of the State of Delaware and the federal laws of the United States, without regard to conflict-of-law rules, unless the law where you live requires otherwise.

Before bringing a claim, you and Melty agree to try to resolve it informally: send the other side a written description of the dispute and allow 30 days to resolve it.

Except for small claims and claims for urgent relief about intellectual property, security or unauthorised access, disputes arising from these Terms or the Services will be resolved by binding individual arbitration administered by the American Arbitration Association under its rules, in Delaware unless agreed otherwise, and may be held by video, phone or in writing.

You and Melty may bring claims only individually, not as part of a class, collective or representative action, unless the law prohibits this waiver. If any part of this section can't be enforced, that part is removed and the rest stays in effect.

21. Everything else

These Terms, with any additional terms that apply to a feature, are the whole agreement between you and Melty about the Services. If a part can't be enforced, the rest still applies. Not enforcing a part isn't a waiver. You can't transfer these Terms without our consent; we may transfer them as part of a merger, acquisition, reorganisation or sale of assets.

We aren't responsible for delays or failures caused by things beyond our reasonable control, including outages, failures of other services, game or platform changes, and natural or political events.
