Terms of Service
Last changed 2026-11-15
1. Who these terms are with
These terms are an agreement between you and Marble Works ("we"), who runs the Tropalm account, Tropalm Cloud AI and the other online services described below (together, "the services"). You can reach us at support@tropalm.com. Please write in Japanese or English; if you write in another language, we will reply in English. If you have a Tropalm account, ask us at support@tropalm.com and, once we have confirmed that the account is yours, we will tell you our name and address without delay.
These terms cover the services only. The game software itself comes under the game licence and the terms of the place you got it from, such as Steam's subscriber agreement or itch.io's terms.
We may transfer these terms, and your account under them, to a company we set up to run the services or to whoever takes the services over from us. We will tell you before we do.
2. Agreeing to these terms
You agree to these terms, and confirm that you have read the privacy policy, when you accept them where the game or tropalm.com asks you to (such as "Agree and start" on the game's first screen), or when you sign in where it says that signing in means agreeing to them. If you do not agree, do not accept them or sign in. You do not need an account to play: companions can run on a model on your own computer, which uses none of the services.
You must be at least 18 years old to sign in. This age limit is for the services; it does not change who may buy or play the game, which follows the store you got it from.
3. Your account
- You sign in with an account from another company, such as Google or Steam. The privacy policy says what we receive from it and what we keep. Your account's settings page says how to link or remove ways of signing in.
- A device stays signed in until it signs out or goes unused for a while. "Sign out everywhere" on your account's settings page ends every session; a session in use when it is ended can keep working for a short time.
- You are responsible for what is done with your account, and for keeping the other company's account you sign in with safe. If you think someone else has used your account, tell us at support@tropalm.com.
Stopping an account
We can stop an account. A stopped account cannot use the services that need an account, such as Tropalm Cloud AI. We can start a stopped account again.
We may stop an account that breaks the rules in section 8 or misuses the services. When an account is stopped, we tell its holder, for example with a notice in the game. If you want us to look at a stop again, write to support@tropalm.com. We do not promise how many days that will take.
4. Tropalm Cloud AI
Tropalm Cloud AI lets your companions think with AI models that run on other companies' computers instead of your own. The game sends what a companion needs to decide what to do next to our server, and our server passes it on to the companies that run the model; the privacy policy says which companies these are. We choose which companies may serve each model; the game's model list shows which models you can pick.
The free allowance
- You can use Tropalm Cloud AI free of charge up to a free allowance. How much it is, the period it is for and who gets it are on the plans page, tropalm.com/plans.
- The allowance is an amount of model use. The game and the account page show how much of it is left. A model that costs more per minute uses it faster.
- When the allowance is used up, Tropalm Cloud AI stops answering for your account until you have allowance again, as the plans page says. You can still play with a model on your own computer.
- Requests are limited in how fast they can be made, separately from the allowance.
- The allowance, who gets it, the models offered and how fast each model uses the allowance can change. Before we make the allowance smaller or take a model away, we let you know, in the game or by email. We do not promise how many days ahead.
The hosted voice
If you choose a hosted voice for a companion, its lines are turned into speech through our server by the companies the privacy policy describes, and what they cost comes out of your allowance, wherever the world is hosted.
What the AI says and does
Companions' words and decisions are generated as you play, by models we do not make. A companion acts on what it has seen, which can be out of date or wrong, and what it says can be wrong. We do not promise that what a companion says or does is correct or suits you, and you should not take it as advice about your health, money, law or safety. We also do not promise that the services will always be available: they can be slow, change or stop, for example when a model company or a company we depend on has a problem.
5. Paid plans
We may offer paid plans. If we do, the plans page and the page where you buy one say what each costs and includes, and the page where you buy one says who sells it. Buying one comes under the seller's terms as well as these.
6. Playing with other people
When you host a world and let others join it, for example with an invite code, you decide who comes in, and the people you let in can see and do what the world allows. We do not watch over games between players. How the game connects players, and which companies help it do so, is in the privacy policy.
7. What you put in
When your companions use Tropalm Cloud AI, the names and descriptions you give them, what you and other players type or say near them, and what happens in your world near them are sent through our server to the model hosts so that your companions can reply.
What you make and type is yours. You give us and the model hosts permission to process it only as far as is needed to run the services, which is to send a companion's request, get its reply and speak its lines. If you choose to send us a record, such as a report of a problem, we may use it to fix bugs and to improve the services. We do not use it to train AI models and we do not use it for advertising.
8. What you must not do
You must not:
- share one account, or one plan, among several people;
- use another person's sign-in;
- use Tropalm Cloud AI or the hosted voice for anything other than playing Tropalm;
- try to reach models or hosts other than the ones the game offers;
- make a new account to get around a stop, or to get the free allowance again, after an account of yours was stopped or deleted;
- break the law or other people's rights through the services, or attack or overload the services or try to get around their limits;
- break the usage policies of the companies that run the models (the privacy policy says which companies these are).
9. Other companies' services
Signing in with another company's account, such as Google or Steam, comes under that company's own terms for it, and the game itself under the game licence and, on Steam, Steam's subscriber agreement. The companies the privacy policy describes handle parts of the services for us.
10. Ending
You can stop using the services at any time. On your account's settings page you can sign out everywhere, or delete your account; the privacy policy says what deleting it removes and what it leaves.
We may end the services, or the free allowance, for everyone. Before we do, we let you know, in the game or by email. We do not promise how many days ahead.
11. Liability
The services are provided as they are. We do not promise that they will suit you or run without interruption or error. We are liable for damage we cause you on purpose or by gross negligence. For damage we cause you by other negligence, we are liable only for the direct and ordinary damage it causes. We are not liable for damage that does not come from our fault, such as a model company's or another company's failure, or what a companion says or does on its own. None of this limits any liability or right that the law where you live gives you whatever these terms say.
12. Changes to these terms
When we change these terms, we put the new version on tropalm.com with its new date. The game carries a copy of these terms, and the first time it starts with a new version it asks you to agree to it before you go on. A change applies to you once you have agreed to it, in the game or by signing in (section 2).
13. Law and disputes
These terms are governed by the laws of Japan, and a dispute about them or about the services is to be heard in the courts of Japan. This does not take away any right that the law where you live gives you to bring a case in its courts.
If part of these terms cannot be applied to you under the law, the rest still applies, and that part applies as far as the law allows.
