Terms of service

Plait is in beta. It is free, invite-only, and still changing. Things will break, and you could lose data. Please read sections 3, 4 and 11 in particular: they explain that you are responsible for what your agents do, and they limit our liability.

1. About these terms

These terms are an agreement between you and Muon Core Ltd, a company registered in England and Wales under company number 09995817, with its registered office at 28 Angel Close, Dukinfield, England, SK16 4XA (“we”, “us”, “our”).

They cover the hosted Plait service at app.plait.run, the plait.run website, and the Plait desktop app and headless executor (the “Software”) (together, the “Service”). By creating an account or using the Service you accept these terms. If you do not accept them, do not use the Service.

If you accept these terms on behalf of an organisation, you confirm that you have authority to bind it. “You” then means both you and that organisation.

Software licence. The Software is proprietary to Muon Core Ltd. While you have an account and comply with these terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the Software to use the Service. You may not copy it (other than to install it and keep a backup), modify it, sell, rent, lend, sublicense or distribute it, or decompile, disassemble or reverse-engineer it, except to the extent the law of England and Wales expressly allows you to (for example under sections 50A to 50C of the Copyright, Designs and Patents Act 1988). Third-party open source components included in the Software remain under their own licences. The licence ends when your account ends or these terms end, and you must then stop using the Software.

Our privacy policy explains how we handle personal data.

2. Business use and your statutory rights

We provide Plait for business and professional use. If you use it as a consumer, for purposes wholly or mainly outside your trade, business, craft or profession, nothing in these terms affects your statutory rights, including those under the Consumer Rights Act 2015. Where these terms say something applies only to business users, it does not apply to you as a consumer.

3. The beta

• Invite only. You can use the Service only if we have invited you, or if a member of an organisation already using Plait has. You must be 18 or over.
• Free. The Service is free during the beta. We do not take payment details. If we introduce paid plans, we will tell you at least 30 days in advance. We will never move you to a paid plan unless you agree to new terms that cover it.
• Unfinished. Features may change, be removed, or not work as expected. There is no service-level agreement, and the Service may be unavailable at times. Keep your own copies of anything important.
• Feedback. We welcome feedback. If you send us ideas or suggestions, we may use them without any obligation to you.
• Ending the beta. We may end the beta, or stop offering the Service, at any time. Where we can, we will give you at least 30 days’ notice and a chance to export your content.

4. Your agents and your AI provider accounts

Plait lets you set up AI agents that act on your instructions. They run on executors on machines you control, use AI providers you choose, and use the integrations and access you give them.

• You are responsible for your agents’ actions. You decide what your agents are allowed to do, and which systems, repositories, integrations and data they can reach. What they do with that access, including messages they send, code they change and actions they take in other services, is done on your behalf, and you are responsible for it as if you had done it yourself.
• Review the output. AI output can be wrong, incomplete or inappropriate. Check it before you rely on it, especially before it reaches other people or production systems. Do not use Plait where a mistake by an agent could cause death, personal injury or serious harm, unless a person reviews every relevant action first.
• Your AI provider accounts and costs. Your agents use your own AI provider accounts, such as a Claude subscription or an API key. You are responsible for complying with that provider’s terms and usage policies, for keeping those credentials secure, and for all fees and usage costs the provider charges you. We do not pay, refund or control those costs.
• Your machines. You are responsible for the machines that run your executors, for keeping them secure and up to date, and for the data and access available to the containers on them.
• Integrations. When you connect a third-party service, you confirm that you are allowed to, and you are responsible for complying with that service’s terms.

5. Your account

• You sign in through an identity provider such as Google, GitHub, Microsoft or your organisation’s single sign-on. Keep that account secure: anyone who controls it can control your Plait account.
• You are responsible for activity under your account, and organisation administrators are responsible for activity in their organisation’s workspace, including by its members, guests and agents.
• Tell us straight away at [email protected] if you think someone has accessed your account without permission.

6. Acceptable use

You must not use the Service, or let your agents or anyone else using your account use it, to:

• break the law, or help anyone else to;
• infringe anyone’s intellectual property, privacy or other rights, or process personal data without a lawful basis;
• access, collect or extract data from accounts, workspaces or systems that you are not authorised to access;
• circumvent, disable or interfere with security features of the Service, or probe or test its vulnerabilities, except through responsible disclosure to [email protected];
• upload or spread malware, or attack, disrupt or place an unreasonable load on the Service or any other system or network;
• send spam or unsolicited messages, or run automated campaigns against people or services that have not agreed to them;
• harass, threaten, deceive or impersonate anyone, including our staff;
• create content that is unlawful, abusive, or that sexualises children;
• copy, resell or provide the Service to others as your own, or decompile or reverse-engineer the server software, except to the extent the law allows you to.

Report abuse or breaches of these rules to [email protected]. Please include enough detail for us to find what you are reporting. We will not tell the person you report who you are, unless the law requires us to.

7. Your content

You own your content: everything you, your organisation and your agents put into or create in the Service. We claim no ownership of it.

You give us a non-exclusive, worldwide, royalty-free licence to host, store, copy, process, transmit and display your content only as needed to provide the Service to you, keep it secure, and comply with the law. This licence ends when your content is deleted from the Service and from our backups. We do not use your content to train AI models.

You confirm that you have the rights you need to put your content into the Service and to let your agents process it. We do not check content in advance, but we may remove content that we reasonably believe breaks these terms or the law.

If your organisation uses Plait to process personal data about other people, your organisation is responsible for having a lawful basis to do so. For that personal data, your organisation is the controller and we are its processor. Our Data Processing Agreement forms part of these terms and applies automatically.

8. Our rights

We, or our licensors, own the Service, including the Plait server software, design and brand. Apart from the licence to the Software in section 1, and third-party open source components under their own licences, these terms do not give you any rights in the Service other than the right to use it under these terms. You need our written permission to use the Plait name or logo, other than to refer to Plait accurately.

9. Third-party services

The Service works with services we do not control, including identity providers, AI providers and integrations. Their terms govern your use of them. We are not responsible for them, for their availability, or for what they do with data you send them.

10. Suspension and termination

• You can stop using the Service at any time. To close your account, email [email protected].
• We may suspend or end your access, or your organisation’s, if you seriously or repeatedly break these terms, if your use puts the Service, other users or third parties at risk, or if the law requires us to. Where it is reasonable, we will warn you first and give you a chance to fix the problem.
• We may also end your access for any other reason, or end the beta. Where we can, we will give you at least 30 days’ notice.
• When your access ends, your right to use the Service stops. Unless we ended it because of a serious breach or a legal requirement, we will give you a reasonable opportunity to get a copy of your content before we delete it. During the beta, you can request a copy by emailing [email protected].
• Sections 4, 6 (for anything that happened before your access ended), 7, 8, 11, 12, 14, 15 and 16 continue to apply after your access ends.

11. Our responsibility to you

Nothing in these terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot be limited or excluded under the law of England and Wales.

Because the Service is a free beta, we provide it “as is” and “as available”. We will provide it with reasonable care and skill, but we do not promise that it will be uninterrupted, error-free or secure, that it will meet your requirements, or that your content will not be lost.

If you are a business user

To the extent the law allows:

• other than our promise above to use reasonable care and skill, we exclude all terms implied by statute, common law or otherwise;
• we are not liable, whether in contract, tort (including negligence), breach of statutory duty or otherwise, for any loss of profits, revenue, business, contracts, anticipated savings or goodwill, for any loss of data other than as set out in the next paragraph, or for any indirect or consequential loss;
• we are not liable for the actions or output of your agents, your AI providers, your executors or third-party services, or for AI provider fees or costs you incur;
• our total liability to you arising out of or in connection with these terms or the Service, in any year, is limited to £100, except as set out in the next paragraph.

For loss or corruption of your content, or a personal data breach, caused by our failure to keep your content secure or by our breach of our Data Processing Agreement or of data protection law, our total liability to you in any year is limited to the greater of £5,000 and the fees you paid us for the Service in the 12 months before the claim. This limit is separate from, and in addition to, the £100 limit above.

You agree that these limits are reasonable, given that the Service is free, experimental, and runs agents that you control.

If you are a consumer

If we fail to comply with these terms, we are responsible for loss or damage you suffer that is a foreseeable result of our breach or our failure to use reasonable care and skill. We are not responsible for loss or damage that was not foreseeable, for any business losses, or for loss caused by the actions of your agents, your AI providers, your executors or third-party services.

12. Claims against us caused by your use

If you are a business user, you will reimburse us for reasonable losses and costs (including reasonable legal fees) arising from a claim by a third party that results from your content, your agents’ actions, or your breach of section 6. We will tell you promptly about any such claim and let you take part in handling it.

13. Changes

We may change the Service at any time; during the beta that will happen often.

We may change these terms. When we do, we will update the date at the top of this page. If a change materially affects you, we will email account holders at least 30 days before it takes effect, unless the change is needed sooner for legal or security reasons. If you do not agree with a change, stop using the Service and ask us to close your account; this costs nothing. If you keep using the Service after a change takes effect, the new terms apply.

14. General

• Entire agreement. These terms are the whole agreement between you and us about the Service.
• Transfer. We may transfer our rights and obligations under these terms to another organisation, for example if our business is sold. If we do, we will tell you and it will not reduce your rights. You may not transfer yours without our written consent.
• Events outside our control. We are not responsible for delays or failures caused by events outside our reasonable control.
• Severability. If a court decides that part of these terms is invalid, the rest continue to apply.
• No waiver. If we do not enforce a right straight away, we can still enforce it later.
• Third-party rights. No one other than you and us has any right to enforce these terms under the Contracts (Rights of Third Parties) Act 1999.
• Notices. We will send notices to the email address on your account. You can send notices to [email protected].

15. Governing law and jurisdiction

These terms, and any dispute or claim arising out of or in connection with them or the Service (including non-contractual disputes or claims), are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that if you are a consumer living in Scotland or Northern Ireland, you may also bring proceedings in your local courts.
