Terms of service

These terms are the agreement for using KUMODeck. KUMODeck is run by the KUMODeck operator ("we"). By creating an account, you agree to these terms. These terms are written in English. If a translation differs from the English version, the English version applies.

Effective date: October 7, 2026

The service#

KUMODeck is a service for building and sharing web apps and games. It gives you a place to host what you make, a database, sign-in, multiplayer, Functions (a place to run your own code) and more, which you use from the dashboard, the command line (kumodeck) or an AI agent (Claude Code, Codex and others).

KUMODeck is in early access. Features and screens may change as we improve them.

Your account#

  • You need your own email address to sign up. Confirm your email address before you add money.
  • If you are under 18, get a parent's or guardian's consent before you use KUMODeck.
  • Keep your password, passkeys and signed-in devices safe. Everything done with your account, including by AI agents and commands you connect, is treated as done by the account owner.
  • You can close your account yourself at any time. See "Closing your account" on the Pricing page for the steps and what to know first.

KUMODeck accounts for players#

If you use "Sign in with KUMODeck" to play games built on KUMODeck, these terms apply to that account too, but the parts about money and about making apps do not.

  • The account is yours. Keep the ways you sign in safe; what is done with your account is treated as done by you.
  • Each game is made and run by its creator, not by us. What happens inside a game is between you and its creator.
  • We may suspend the account for the reasons in "When we may stop or delete" below. While it is suspended, you cannot sign in with it to any game.
  • You can delete the account at any time on your KUMODeck account page. How we handle its data is in the Privacy policy.

Prepaid balance and refunds#

  • Usage fees are taken from your prepaid balance for what you use. There is no free tier. Prices and how they are counted are on the Pricing page.
  • The balance is in US dollars and you add money by card ($0.50 to $10,000 each time). The card fee is added to the payment, and the amount you chose goes into your balance. The balance does not expire.
  • When your balance reaches $0, everything that costs money stops until you add money, and starts again automatically when you do. Use automatic top-up if you do not want it to stop.
  • In principle, we do not accept cancellations or refunds after you add money, except where the law requires a refund. When you close your account, after that month's usage is final we refund the unused part of what you added by card to that card (the card fee is not returned, and anything you owe us is taken first).
  • Invite credit (credit received with an invite code) can only be used for usage fees and cannot be refunded. It is removed when you close your account.
  • For details, see "Prepaid balance" and "Closing your account" on the Pricing page.

What you make is yours#

  • The apps and games you make, and the code, images and data you upload, belong to you. We do not take any rights to them.
  • We store, copy and send them only as needed to host, serve and run your apps and games. When you delete them, we stop using them (except records the law requires us to keep, and database backups kept for up to 30 days; see "How long we keep it" in the Privacy policy).
  • Only upload things you have the right to use.
  • What is in your apps and games, and your relationship with their users (the data you collect from them, what you promise or tell them), is yours to decide and your responsibility. How we handle your users' data is in the Privacy policy.
  • KUMODeck itself (the service, the docs, the name and logo) stays ours.

AI-generated content#

Version: October 15, 2026

  • KUMODeck lets you and your AI agent use outside AI companies (for example Tripo for 3D models and fal for images). What to make is decided by you and your AI agent, not by us.
  • What you may do with the results follows that company's terms. We do not claim any rights to the results. AI results may not be unique: the same or similar results can be made for other people.
  • Do not use these features to make anything illegal, anything that infringes other people's rights (for example someone else's characters, or a real person's likeness without their permission), or anything that company's terms do not allow. The Acceptable use rules apply too.
  • The cost is taken from your prepaid balance at what the AI company charged, with no markup. Before a job starts, your balance must cover the highest it could cost. If a job fails on KUMODeck's side, it is not charged. If it fails at the AI company, only what that company charged for the attempt is taken.
  • The first time you use these features, you are asked to agree to this section (for example by telling your AI agent), and we record that you agreed and to which version.

What is not allowed#

What you must not do is on the Acceptable use page. That page is part of these terms.

When we may stop or delete#

We may stop serving an app or game, delete its contents, or suspend an account:

  • when it breaks the Acceptable use rules, or while we check a report that it does,
  • when we need to stop it right away to protect KUMODeck or other users (for example an attack, or a heavy load on the service),
  • when the law, a court or another public authority requires it,
  • when payments to us are overdue.

After a report of abuse, this is what happens:

  1. Anyone can tell us on the report page. You do not need an account.
  2. We check the report. When needed, we stop serving the app or game while we check. While it is stopped, its users cannot use it, but your code, data and settings are kept and you can still sign in to the dashboard.
  3. When we stop it or start it again, we email the owner at their confirmed email address, with the kind of reason and where to contact us. We do not share who reported it or what the report said.
  4. If there is no problem, we start serving it again. If the problem is serious, we may delete its contents after stopping it. Deleted contents cannot be brought back. We email you when we delete them too.

If you think we stopped or deleted something by mistake, tell us at [email protected].

What we do not promise#

  • KUMODeck is provided as it is. We do not promise that it will never stop, never be slow, have no mistakes, or fit a particular purpose.
  • We do not promise that data will never be lost. Keep your own copies of important data and code.
  • Card payments and other companies' services, such as AI agents, follow those companies' own terms.
  • We may change or end features. If we end KUMODeck as a whole, we will email you in advance and refund your unused prepaid balance.

Limit of liability#

  • Our total liability related to KUMODeck is limited to the amount you added to your balance in the 12 months before the day the damage happened (invite credit is not counted).
  • We are not liable for indirect damage or for profits you could have made.
  • These limits do not apply if we acted on purpose or with gross negligence, or where the law does not allow such limits.

Changes to these terms#

When we change these terms, we post them on this page and update the effective date. For important changes, we also email creators before the effective date. If you keep using KUMODeck after the effective date, you agree to the new terms. If you do not agree, close your account (your balance is refunded as described in "Prepaid balance and refunds" above).

Governing law and court#

These terms are governed by the laws of the place where the operator of KUMODeck is located. Any dispute about KUMODeck will be handled exclusively by the courts that have jurisdiction over the operator's location.
