The terms for using Velven.

You must be at least 13 years old to use Velven. If you are under the age of majority where you live, a parent or guardian must agree to these terms for you.

Browsing and playing need no account. Listing a space on Velven, commenting, joining rooms, adding friends and posting scores under your handle need one. Publishing without an account makes an unlisted page, as described below. If you use Velven for an organisation, you agree to these terms on its behalf and confirm you are allowed to.

Give accurate details, keep your sign-in secure, and keep your agent and CLI tokens private: you are responsible for everything done with your account and its tokens. Accounts are personal and may not be sold or transferred.

Your handle is your public name and address on Velven. Velven may take back or change a handle that impersonates someone, uses another's trademark, or misleads people.

You can publish a space's files to Velven's hosting, or list a space that runs at its own address. Either way, you confirm that you made it or hold every right needed to put it on Velven, including the rights to its code, art, music, fonts and any other assets in it, that the details you give about it are accurate, and that it follows the content policy.

Velven reviews what it hosts, as the content policy describes, and may refuse a version or hide a space that breaks it. A linked space runs on its own host, under that host's terms as well as these.

Velven also lists some public spaces it finds, credited to their creators, who can claim them. A creator who claims the listing can manage it, or have it taken off Velven.

You can publish a space's files without an account. Doing so means you accept these terms, and everything in them applies to what you publish. It makes an unlisted page: a page on velven.ai, reviewed the same way, marked unclaimed, that anyone with its link can open but that Velven does not list, rank or show in search.

Velven gives you a claim token with the page. It is the key to the page: whoever holds it can publish new versions to it or claim it, so keep it private. Velven stores only a fingerprint of it and cannot show it to you again.

An unclaimed page is deleted 7 days after its first publish, with its files and everything players saved on it; publishing again does not extend that. To keep it, claim it within those 7 days with an account, using the token. Claiming makes the space yours under these terms and puts it on Velven. To keep the service fair, Velven limits how much can be published without an account from one network address.

Velven's builder makes a game from what you write to it and the pictures you add. Your game is yours, and when you publish it, it is a space like any other under these terms.

The pictures, 3D models, 2D characters, sound effects, music and other assets the builder makes for your game are yours to use, on Velven and elsewhere. Velven stores them with your game and uses them to run the builder and your game. It also keeps a record of each one except music: the game it was made for, what it was asked to make, and whether it was made from a picture you added.

Each game has sharing settings, one for each type of asset: 3D models, pictures, 2D characters and sound effects. You find them under Manage sharing in the game's menu in the builder and when you publish it, and the defaults every new game starts with in your settings. While a type is turned on, Velven records the assets of that type the game makes so that it may later offer them to other games made on Velven, including other people's, and their makers may use them in those games under these terms.

A new game starts with your account's default sharing, which you set in settings and which has every type on until you change it. A type that is on by default stays on only while every asset of that type in the game was made from Velven's own pictures and words. Once one is made from a picture you added, that type turns off, even if you had turned it on, and stays off until you turn it on again; turned on then, it covers the assets of that type the game makes from then on, those made from your pictures included. Turning a type on never covers an asset the game made while it was off. Velven never offers the music it makes for your game to anyone else. You can change any of these settings at any time. Turning a type off stops Velven offering the game's assets of that type; a game that already uses one of them keeps it.

The pictures you add stay yours. You confirm that you may use them, and you give Velven a licence to store them, to send them to the AI providers it relies on, and to use them to make your game and its assets. Velven never offers a picture you added to another game.

When you delete a game, Velven deletes it with its files and its assets 30 days later, except the assets Velven recorded under a type that was turned on when the game was deleted: Velven keeps those and their files, so it may still offer them, until you delete your account. Assets another game already uses stay in that game.

Your space stays yours. By putting it on Velven, you give Velven a worldwide, non-exclusive, royalty-free licence, for as long as it is on Velven, to:

• host, store, copy, serve, frame and display it, and run it for players on Velven;
• add the Velven SDK tag to it and make the technical changes needed to serve it;
• take screenshots, captures and short clips of it, and use them with its title, description and your handle on Velven and to promote Velven and your space, including on social media.

You can hide or delete a space at any time. Velven then stops showing it within a reasonable time. Copies in backups can take longer to clear, and promotion already published before you removed it may stay up.

Comments, room chat, scores, saves, a status line a space shows your friends, and the content you upload through a space (levels, replays, maps and the like) are yours, and you are responsible for them. They must follow the content policy.

You give Velven a licence to host, store and show what you post where you posted it, and you give the space's creator the right to use it in their space as its features intend, for example letting others play a level you shared. Public content can be seen by anyone; private content only by you. Room chat reaches everyone in the room, and a room's host can remove a player from it. A space's creator can delete comments on their space and content uploaded to it, and Velven can delete anything.

Everything the content policy rules out, and also:

• breaking the law or someone else's rights;
• showing Velven's review something different from what players get, or changing a live space to get round it;
• attacking, overloading or probing Velven or anyone's space, or getting past Velven's limits, rate caps or access controls;
• faking plays, likes, reports or scores, or using automation to move rankings;
• collecting other people's information from Velven without their permission;
• harassing, threatening or impersonating anyone, Velven included, and spam.

Velven offers an SDK, an agent API, a command-line tool and an MCP server for building on it. Use them as the documentation describes. Keep your tokens and your space's secret private: what is done with them is done by you.

What Velven gives your space about a player (their account ID, handle and avatar, their scores and saves) may be used only to run your space for them. Do not sell it or use it to contact them elsewhere.

Velven may set limits on these tools, change or retire them, and turn off access that is misused. The SDK's code is published under its own open-source licence, which governs the code; these terms govern your use of Velven through it.

Velven may remove, hide or refuse any space, version, comment or content, and may suspend or close any account, at any time and with or without notice, including when it believes something breaks these terms, puts players or Velven at risk, or when the law requires it. Velven closes the accounts of repeat infringers, as the takedown page explains.

You can delete your account at any time in settings: it takes your spaces off Velven and deletes your profile, scores, saves and uploads, and the files of the spaces you published on Velven 30 days later. The sections on licences already given, warranty, liability and indemnity continue after an account is closed.

Spaces are made by their creators, not by Velven. Velven does not review every space in full and is not responsible for what a space does or says, or for the sites it links to. If something is wrong, use Feedback on the space's page.

Velven is provided as is and as available. To the extent the law allows, Velven makes no warranties, express or implied, including of merchantability, fitness for a particular purpose and non-infringement, and does not promise that the service will be uninterrupted, secure or free of errors, or that hosted files, scores, saves or content will be kept. Keep your own copies of what you publish.

To the extent the law allows, Velven is not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, data or goodwill, arising from your use of Velven, even if told they were possible. Velven's total liability for any claim about the service is limited to the greater of 100 US dollars and the amount you paid Velven in the 12 months before the claim. Some places do not allow these limits, so they apply only as far as the law there allows.

If someone brings a claim against Velven because of your space, what you posted or your breach of these terms, you agree to cover Velven's reasonable losses and costs from it, legal fees included.

Velven may change these terms. The date at the top changes with them, and a significant change is announced on Velven before it takes effect. Using Velven after a change means you accept the new terms; if you do not, stop using Velven and delete your account.
