Terms of service

Last updated: October 22, 2026

1. The agreement

These terms are between you and Triangle Interactive, LLC (“we”, “us”), the operator of Gensprite — the service at gensprite.ai and api.gensprite.ai that generates game art and audio, and playable games built with GigaEngine, reached through the web workshop and HTTP API. Using either means accepting these terms.

2. Your account

You must be at least 13 years old. Accounts are passwordless — you sign in with an email link or through Google or GitHub — which means your email inbox is effectively your credential, and keeping it secure is your responsibility. So are your API keys: each secret is shown once, we store only a hash, and everything done with a key counts as done by you. A key spends whatever your account holds unless you give it a spend limit in Settings. Revoke lost keys in Settings immediately.

3. Credits

Generations cost credits. The price of every kind of generation is quoted before you commit — on the bench, or via the API’s quote endpoint — and is never buried in a document like this one. How credits behave:

  • New accounts receive a one-time grant of 150 credits, valid for 365 days.
  • Until an account makes its first payment, for a credit pack or a subscription plan, the sprites, turnarounds, animations and images it generates are delivered as watermarked previews and cannot be downloaded. The originals are kept, and any such payment makes the originals of everything generated before it available.
  • Credit packs are one-off purchases, valid for 365 days from purchase.
  • Plans grant credits each billing period. Unspent plan credits carry into the next period up to one period’s allowance; the rest expires. When a plan lapses, its remaining credits expire at the end of the period already paid for.
  • Credits are always spent from the soonest-expiring batch first.
  • Balances migrated from the previous version of Gensprite never expire. That promise predates these terms and survives them.
  • A generation that fails or is cancelled refunds its credits automatically and in full. Credits have no cash value and, apart from what the refund policy says, are not convertible back into money.

4. Purchases

Payments are processed by Stripe. An account holds at most one running plan; plan changes, proration, tax and failed-payment handling are managed through Stripe’s billing portal, reached from the Billing page. Cancelling a plan stops future charges — the period already paid for runs to its end, and nothing already granted is taken back. Refunds of money are covered by the refund policy.

5. Your content

What you make is yours. You retain ownership of the prompts and images you provide and of the sprites, turnarounds and animations generated for you, and you may use them for any purpose, commercial ones included, with no attribution owed. You grant us only the license needed to operate the service: to process your inputs through our generation providers and to store the results for you. We do not train models on your content, and we do not showcase your work publicly without asking you first.

You are responsible for what you put in — inputs must not infringe anyone else’s rights — and for confirming that your use of generated output is lawful in your jurisdiction. The service itself, its code and design, remains ours. Games have sections of their own, below.

6. Games

Gensprite also makes games. You describe one, and an agent builds it in GigaEngine, our game engine: it writes the code, generates the art with Gensprite’s own generators, plays the result and hands over a build you can play in the browser. How games are paid for:

  • Every account can make one game for free: one prompt, on the default model, under smaller limits than a paid prompt. Its model time is free; the art the agent generates for it is paid from the account’s credits, the signup credit included, as described below. It can be played on Gensprite; downloading it takes the Game pack, as with any other game.
  • Making more games, and sending a game further prompts, needs an account that has made a payment, as in section 3. A prompt has no fixed price and holds nothing back: it is charged in credits as the agent works, for its model time, from the same balance as everything else. The agent works until the game is done or the balance runs out. A prompt that ends without a playable build of its own, whether it fails or you stop it, gives back what its model time was charged.
  • Downloads come with the Game pack, a one-off purchase that also includes credits. Once bought, it unlocks downloads for every game on the account, those made before it included, and spending its credits does not take them away. A download is the game’s newest build for the web, ready for itch.io or any web host, and for Windows when that build was made for it, and its GigaEngine project.
  • The art the agent generates for a game is bought with your credits, piece by piece, like any other generation, through a key made on your account for that prompt alone and deleted when it ends. There is no separate art budget: the agent may use as much of the balance as it needs. Each piece stays in your account whatever becomes of the game, a piece that fails is refunded as usual, and none of it carries a watermark, whether or not the account has paid for anything else.

Your games are yours. As between you and us, you own the prompts you send and the game the agent makes from them: its code and scripts, its scenes and data, and its art and audio, everything in the project you download. To the extent we hold any rights in that output, we assign them to you. You may change, publish and sell your games, commercial use included, with no royalty owed. You grant us only the license needed to make and keep them for you: to run the agent and our model provider on your prompts and your project, to store the project so the next prompt continues from it, to host its builds so you can play them, and, while a game is public, to show it as the next paragraph describes. We do not train models on your games.

Games are public unless you make them private. A new game gets a page on gensprite.ai where anybody with the link can play its newest build, and it can be listed in our gallery of games. That page shows the game’s title, the prompt it was first made from and a screenshot from the agent’s playtest, and offers code to embed the game on other websites; it never shows your name or email. An account that has bought credits can make any of its games private, or public again, at any time from the game’s page, and a game made private leaves its page and the gallery within minutes. Games made before public pages existed stay private unless you make them public. We may take any game’s public page down at our discretion.

Two things in a download are not yours: the GigaEngine runtime, licensed to you under section 7, and third-party fonts or libraries, which come under their own licenses. Generated output is not guaranteed to be unique — someone else’s prompt can produce a game much like yours — and some jurisdictions do not protect material a machine generated without enough human authorship. You are responsible for your prompts, which must not ask for anyone else’s characters, brands or other protected work, and for what you do with a game once you ship it: store rules, age ratings, and your obligations to the people who play it.

7. GigaEngine in your games

A build carries the GigaEngine runtime: the engine code that plays the game, in a browser for a web build and as the game’s executable for a Windows build. Unlike the game, the runtime is not yours. It is closed source and stays ours; it is licensed to you, not sold.

With a game you downloaded from Gensprite, you may use, copy and distribute the runtime, unmodified and as part of that game, anywhere and for any purpose, selling the game included. The license is worldwide, non-exclusive and royalty-free, and no credit to GigaEngine is required. It extends to the players and stores you distribute the game through, and to anyone you sell or license the game to. It does not expire: closing your account, or a later change to these terms, does not take it back from a game already downloaded.

It does not cover distributing the runtime on its own or inside another engine or tool, modifying it, or decompiling or reverse-engineering it beyond what the law allows regardless, and the notices that come with the runtime must stay with it. Notices inside the runtime that reserve GigaEngine’s rights do not narrow this license. Third-party components inside the runtime keep their own licenses, whose texts travel with it. The GigaEngine editor and command-line tools are not part of a download, and this license does not cover them.

8. Acceptable use

  • No content that is illegal or infringes others’ rights.
  • Generations refused by the safety checker fail and refund automatically; repeatedly attempting to circumvent it is a violation of these terms.
  • No interfering with the service: probing, overloading, reselling access, or sharing API keys to evade limits.
  • No using a game’s agent or the machine it works on for anything but making that game: not to reach other systems, and not to get at the keys it works with.
  • No games made to harm the people who play them: malware, phishing, or collecting players’ data without telling them.

We may suspend or terminate accounts that violate these terms. Credits in an account terminated for violations are forfeited.

9. The service, as it is

Gensprite is provided as is. Generative models are probabilistic: a completed job means the pipeline ran, not that the art meets your hopes, and quality of output is not warranted. The same goes for games: a finished prompt means the agent left a playable build, not that the game is free of bugs or the one you pictured. We do not promise uninterrupted availability. Generated files are retained as described in the privacy policy — kept while your account has credits or a plan, and for 90 announced days after it empties. Games are not on that clock; if we ever set a limit on how long they are kept, we will announce it by email before anything is deleted.

10. Liability

To the maximum extent the law allows, we are not liable for indirect, incidental or consequential damages, and our total liability for any claim is capped at the amount you paid us in the twelve months before the claim arose.

11. Changes and governing law

We may update these terms; the date above changes when we do, and material changes are announced by email. These terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-laws principles.
