Terms of Service.

The agreement #

These terms are a binding agreement between you, the person or business holding the account, and Stacklumen LLC ("Stacklumen", "we", "us"). They govern the Stacklumen products: the Hub (the dashboard where agencies run clients, projects, the team and billing), Terminal (the site designer, CMS, forms, publishing and hosting) and Baselumen (the component library, templates, designer and web tools), together with their APIs, agent connections, the Marketplace and the Developer Center ("the products" or "the service").

You accept these terms by creating an account, by ticking the box that asks you to, or by using any of the products. Using one product means accepting these terms for all of them, because they share one account, one workspace and one plan. If you accept on behalf of a business, you confirm that you have authority to bind it, and "you" means that business as well as you.

These policies are part of these terms, as if they were written here: the Private Alpha Terms, the Billing, Refunds and Chargebacks policy, the Acceptable Use Policy, the Agent and API Terms, the Marketplace Terms, the Privacy Policy, the Data Processing Terms and the Copyright and Takedowns policy. Where they conflict, the order of precedence is: a written agreement signed by both of us for that matter, then the Private Alpha Terms while the products are in alpha, then the Acceptable Use Policy, then these terms, then the other policies.

These terms govern the products: the applications you subscribe to yourself, monthly or yearly, in-app. They do not govern engineering engagements. A build, a retainer, a migration or a hosting and maintenance plan is covered by the Client Portal and Services Terms and the statement of work for it. If you both subscribe to a product and have Stacklumen do engineering work for you, both apply, each to its own part, and nothing in one changes the other.

Eligibility and accounts #

• You must be at least 18 years old and able to form a binding contract. The products are not directed at children, and an account held by somebody under 18 will be closed.
• You may not use the products if you are located in, or ordinarily resident in, a country subject to comprehensive US sanctions, if you are named on a US government restricted-party list, or if we have previously closed an account of yours for a breach of these terms.
• Give accurate information when you sign up, and keep it current. An account is a person: one account per person, never shared, and never a seat passed between people.
• Keep your sign-in credentials, API keys and agent tokens secret. You are responsible for everything done under your account, by your members and guests, and through your keys and tokens, whether or not you authorised it. Tell us at once at support@stacklumen.com if you think any of them has been compromised.
• Public addresses (an agency or profile at stacklumen.com/your-name) are granted, not owned. We may refuse, reclaim or change an address that is misleading, infringes somebody else's rights, impersonates a person or brand, or is reserved.
• We may refuse to open an account, or decline to provide the service to anyone, at our discretion.

Agencies, workspaces, members and clients #

An account is a person. A workspace holds the team roster, the clients and the work. The agency, the business that holds one or more workspaces, is the customer: it owns the subscription, and its plan covers every workspace it holds.

• The owners of the agency's workspaces manage its billing. Each workspace's owners and admins manage its members and its content, and are responsible for who they let in.
• You are responsible for what the people you invite do in your workspace, including members, client guests and referral partners, as if you had done it yourself.
• Removing somebody from the roster removes their access to every product in the suite at once.
• Clients you add, and the guests you invite into a client portal, client chat or shared files, are your customers, not ours. You control what they can see, you are responsible for what you share with them and publish to them, and you are responsible for having a lawful basis, and any notices and consents the law requires, for the client and personal data you put into the products.
• The products help you run your business. They do not make Stacklumen a party to any agreement between you and your clients, and we are not responsible for your work, your fees or your disputes with them.

Plans, fees and payment #

Each agency has one subscription. It carries the agency's plan (Free, Pro or Agency, monthly or yearly), any extra seats and workspaces, and a site plan for each site on its own domain. Paid plans are charged in advance, renew automatically until cancelled, and are billed through our payment processor, Stripe. Each agency may take one 14-day trial of the Agency plan. The Billing, Refunds and Chargebacks policy sets out how billing, renewal, the trial, cancellation, failed payments and taxes work, and it is part of these terms.

During the private alpha, billing is not switched on: plans are not sold and no subscription is charged. We will give notice before billing is switched on, and you will see the price and choose before anything is charged. Purchases from the Marketplace are charged when you make them.

Fees are non-refundable, except where the billing policy says otherwise or the law requires it. That includes partial periods, unused time, seats, workspaces and site plans, and plans you did not use.

Chargebacks. If you think a charge is wrong, write to support@stacklumen.com first. Disputing a valid charge with your bank or card issuer is a breach of these terms. When a dispute is opened we may suspend the agency's workspaces, sites, keys and agents until it is resolved, and you owe the disputed amount together with the processor's dispute fees. The billing policy sets this out in full.

Acceptable use #

Using our platform for anything illegal is a violation of our terms of service and will result in immediate deplatforming — removal of the offending content, revocation of access, and closure of the account — and referral to law enforcement partners where required or applicable.

All sexual abuse material is reported to law enforcement, and we do not allow pornographic content on our platform in any shape or form.

The Acceptable Use Policy applies to everything in your workspace, everything you publish through the products, and everything done with your account, keys and agents.

Your content #

You own everything you put into the products: your projects, sites, pages, files, CMS items, components, designs, client records and messages ("your content"). We claim no ownership of it, and we do not use it to train machine-learning models.

You give us a worldwide, non-exclusive, royalty-free licence to host, store, copy, cache, transmit, display, reformat and process your content, only as needed to operate, secure and support the service for you, including serving the sites you publish and keeping backups. The licence ends when the content is deleted from the service, except for copies in backups until they expire, and anything you chose to make public through a listing or a public page while it stays listed.

• You confirm that you have every right, licence and consent needed to put your content into the products and to have us process it, and that it does not infringe anybody's rights or break any law.
• We do not review content before it is stored or published, and we are under no obligation to monitor it. We may remove or disable access to any content that we believe breaks these terms or the law, or exposes us or others to harm.
• Keep your own copies. You are responsible for exporting and backing up content that matters to you. We keep backups to run the service, not as a backup service for you, and we do not promise any content can be restored.
• Some content is public by design. Published sites and their files, public profiles and listings, and images and files uploaded to a design in the designer are served at public addresses that anybody with the link can open. Do not put anything confidential in them.

We measure how the products are USED (runs, page views, feature counts). We do not read what you write. This is enforced by an explicit column allowlist in the database rather than by policy alone. See the Privacy Policy.

Published sites, forms, hosting and domains #

Terminal publishes sites to the internet: to staging links, to the addresses we provide and to domains you connect. Stacklumen hosts and serves them on your behalf. You are the publisher of every site, page, form and file you publish, and you are responsible for it as a publisher.

• You are responsible for your sites' legal compliance: their privacy policies, cookie notices and consent, accessibility, consumer law, advertising rules, and the claims they make.
• Forms on your sites collect your visitors' data for you. You are the controller of that data; we process it for you under the Data Processing Terms. Do not use forms to collect passwords, full card numbers, government identity numbers or health data.
• You may connect only domains you own or control. Stacklumen does not sell or register domains: registration, renewals, DNS and the registrar's own terms are yours, and fees paid to a registrar are theirs. Connecting custom domains may be paused or limited during the alpha.
• App routes serve an application you host elsewhere at a path of your site. That application, its code, its data and its availability are yours; we only pass requests to it, and we may stop doing so if it breaks these terms.
• Sites on the free plan, and staging links, may carry a Stacklumen badge and are held to the limits of the plan.
• We may take a site, page, form or file offline at once, without notice, if it breaks the Acceptable Use Policy, is the subject of a valid legal complaint, or puts the service or other customers at risk.

Imports, web tools and the URLs you supply #

Several tools act on addresses and repositories you give them: importing a repository into Terminal (which also reads the live site it names, and copies its images and assets), pushing and pulling through GitHub, fetching assets from a URL, and Baselumen's audit and analysis tools. When you supply an address or a repository, you confirm that you own it or are authorised by its owner to copy, change, scan or test it.

• An import copies pages, styles and assets into your workspace. Do not import anything you do not have the right to copy. Importing somebody else's site to clone, impersonate or phish it is a breach of these terms.
• Pushes and pull requests made from Terminal change your repository. Review them; you are responsible for what is merged and deployed from it.
• Some audit tools send the address you test to a third-party testing service, as the Subprocessors page lists.
• Running an audit against somebody else's property without permission may be unlawful where you are. The audit tools are for sites you own or are authorised to test.
• Audit and analysis tools report findings. They do not guarantee that a site is secure, accessible, compliant, fast or correct. Acting on a finding is your decision, and the outcome is your responsibility.

Agents, API keys and automation #

The products can be operated by software: AI agents connected over MCP, the in-app agent running on your own AI provider key, content API keys, webhooks, and apps and connectors installed from the Marketplace. The Agent and API Terms govern them and are part of these terms. In short: whatever an agent, key or token does under your account is done by you. Review what agents propose before it is published, keep keys secret, give each one the narrowest scope it needs, and revoke any you no longer use.

Third-party AI tools you connect are not Stacklumen products. Their output can be wrong, and their providers' terms apply to what you send them. We are not responsible for what a third-party agent does, says or sends.

The component library and the Marketplace #

The Baselumen library. What you build with the library's components and templates is yours. Your plan licenses you to use them in unlimited personal, commercial and client projects, and you keep what you have already built into a project after your subscription ends. The library itself stays ours: you may not repackage, redistribute or resell the components or templates as a library, template kit, theme, UI kit or design asset of their own, or use them to build a product that competes with the library.

The Marketplace. The Marketplace lists templates, components, apps, connectors and programs, some made by Stacklumen and some by other members and developers. Buying, selling, listing and installing are governed by the Marketplace Terms, which are part of these terms. In short: purchases are final, a licence belongs to one workspace, sellers are paid their share by hand, and anything installed is installed at your own risk.

Third-party services #

The products work with services we do not control: payment processing, GitHub, domain registrars, email providers, AI tools and anything you connect through the Marketplace. Your use of them is governed by their terms, and we are not responsible for their availability, their security, what they do with your data or any change they make that affects the products. If a third party withdraws or changes a service, we may change or remove the feature that relies on it.

Our property, and what you may not do with it #

The products, the library, the Stacklumen Design Language and frameworks, our documentation, our brands and everything we make available, other than your content, belong to Stacklumen and its licensors. These terms give you a limited, revocable, non-exclusive, non-transferable right to use the products for your own business and your clients' work while your account is in good standing. Nothing else is licensed.

You may not, and may not help or allow anybody else to:

• copy, frame, mirror, resell, sublicense, rent or provide the products to third parties as a service, except to your own clients through the features built for that;
• reverse-engineer, decompile or attempt to extract source code, models, prompts or system instructions from the products, except where the law expressly permits it;
• scrape or bulk-download the products, the library or the Marketplace, or use automated means to access them except through the APIs and agent connections we provide and within their limits;
• bypass any limit, plan gate, usage cap, rate limit, security measure or access control, or open further agencies, workspaces or accounts to obtain further trials or free allowances;
• remove or alter any notice, badge, attribution or mark we place, except where your plan allows it;
• use the products, or anything obtained from them, to build or train a competing product.

Feedback. If you send us ideas, bug reports, suggestions or requests, you give us a perpetual, irrevocable, worldwide, royalty-free licence to use them for any purpose, without obligation or payment to you.

Availability, changes and support #

The products are pre-release software in a private alpha, and the Private Alpha Terms apply on top of these terms. We aim to keep the service available and to fix what breaks promptly, but we do not offer a service level or uptime commitment. Maintenance, third-party outages, attacks and faults will interrupt it.

We may add, change, limit or remove any feature, product, plan or limit at any time. Where a change removes something you rely on, we will try to tell you first, but we are not obliged to keep any feature.

Support is by email at support@stacklumen.com and through the in-product support form, with a public form that needs no sign-in for when you cannot get into your account. Support is provided on reasonable efforts, with no guaranteed response time.

Suspension and termination #

• You may stop using the service and cancel at any time, as the billing policy describes. Cancelling does not end amounts already owed.
• You may delete a workspace, which permanently removes it and everything in it. That action asks you to type DELETE, because it cannot be undone.
• We may suspend or restrict any account, workspace, agency, site, key or agent immediately, without prior notice, where we believe it is breaking these terms or the law, where a payment has failed or been disputed, where it poses a security or legal risk to the service, to us or to anybody else, or where the law or a valid legal request requires it.
• We may terminate your access for a breach of these terms, for non-payment, for a chargeback, for repeated infringement, or where the law requires it, without prior notice and without refund. We may also end the service, or your access to it, for any other reason on 30 days' notice, in which case we refund any fees you prepaid for the period after it ends.
• Where we reasonably can, and where it would not compromise an investigation, the service or anybody's safety, we tell you why we acted.
• After termination you may ask, within 30 days, to export your content, unless we terminated for illegal content or conduct. After that we may delete it, subject to the retention set out in the Privacy Policy.
• Sections that by their nature should survive termination do, including ownership, licences you granted, fees owed, disclaimers, limits of liability, indemnity and disputes.

Disclaimers #

The products, the library, the Marketplace, the tools and everything made available through them are provided "as is" and "as available", with all faults, and without warranty of any kind. To the fullest extent the law allows, Stacklumen disclaims all warranties, express, implied or statutory, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy and quiet enjoyment, and any warranty arising from a course of dealing or usage of trade. We do not warrant that the products will be uninterrupted, secure, error-free or free of harmful code, that content will be preserved or recoverable, that defects will be corrected, or that any result, finding, ranking, traffic or revenue will follow from using them.

Limitation of liability #

To the fullest extent the law allows, Stacklumen and its members, officers, employees, contractors and licensors will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, business, goodwill, data or content, or the cost of substitute services, however caused and on any theory of liability, even if told they were possible.

Stacklumen's total liability for all claims arising out of or relating to these terms or the products, together, will not exceed the greater of (a) the fees you paid to Stacklumen for the products in the twelve months before the event giving rise to the first claim, and (b) one hundred US dollars (US$100).

These limits apply even if a remedy fails of its essential purpose, and they are an essential basis of the price. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.

Your indemnity #

You will defend, indemnify and hold harmless Stacklumen and its members, officers, employees and contractors from and against every claim, demand, loss, liability, fine, cost and expense (including reasonable legal fees) arising out of or relating to: your content; your sites, forms and anything you publish or host through the products; your clients, guests and members and your dealings with them; anything done through your account, keys or agents; your listings in the Marketplace; your breach of these terms or of the law; or your infringement of anybody's rights. We may take control of the defence of any such claim at your expense, and you will not settle one without our written agreement.

Disputes and binding arbitration #

Please read this section carefully. It requires disputes to be decided by an arbitrator rather than a court, one by one rather than as a class, and without a jury.

Informal resolution first. Before either side starts arbitration or a court claim, it must write to the other (to us at support@stacklumen.com; to you at the email on your account) describing the dispute and the resolution it wants, and both sides must try in good faith to settle it for 30 days.

Binding individual arbitration. Any dispute, claim or controversy arising out of or relating to these terms, the products or the relationship between you and Stacklumen, including whether this section applies, will be settled by final and binding arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, or its Consumer Arbitration Rules where those apply to you, before a single arbitrator. The arbitration will be held in Lexington, Kentucky, or by video or written submissions where the arbitrator allows. The Federal Arbitration Act governs this section, and judgment on the award may be entered in any court with jurisdiction. Fees are paid as the applicable rules provide.

What is not arbitrated. Either side may bring an individual claim in a small-claims court that has jurisdiction, and either side may ask a court for an injunction or other urgent relief to protect its intellectual property, its confidential information or the security of the service, or to stop a breach of the Acceptable Use Policy.

You and Stacklumen each agree that disputes will be brought and decided only on an individual basis, and not as a plaintiff or class member in any class, collective, consolidated or representative proceeding. The arbitrator may not consolidate the claims of more than one person or award relief to anybody other than the individual party. You and Stacklumen each waive any right to a trial by jury.

Opting out. You may opt out of arbitration by writing to support@stacklumen.com, with the subject "Arbitration opt-out" and the email address of your account, within 30 days of first accepting these terms. Opting out does not change anything else in these terms.

Time limit. To the extent the law allows, a claim must be brought within one year after it arises, or it is permanently barred.

If part of this section fails. If the class-action waiver is found unenforceable for a claim, that claim, and only that claim, goes to the courts named under Governing law rather than to arbitration, and it is stayed until any arbitrable claims are decided.

Governing law #

These terms are governed by the law of the Commonwealth of Kentucky, USA, and applicable US federal law, without regard to conflict-of-laws rules. The UN Convention on Contracts for the International Sale of Goods does not apply. Any dispute that is not arbitrated goes exclusively to the state or federal courts in Fayette County, Kentucky, and both sides consent to their jurisdiction.

Nothing in these terms removes a right you have under the consumer law where you live that cannot be excluded by contract. Where such a law gives you a stronger right, that law applies, and only to the extent it requires.

Changes to these terms #

We may change these terms. Each document carries its version and effective date, and material changes are announced in the products or by email before they take effect. Continuing to use the service after a change takes effect means accepting it; if you do not accept it, stop using the service and cancel. A change to the disputes section does not apply to a dispute either side had already notified before the change.

General #

• Entire agreement. These terms and the policies they incorporate are the entire agreement between us about the products, and replace anything said or written before. Plain-English summaries, headings and the key points above a document are for convenience only and are not part of it.
• Severability. If any part of these terms is found unenforceable, it is enforced to the fullest extent possible, and the rest stays in force.
• No waiver. Not enforcing a term is not a waiver of it.
• Assignment. You may not assign or transfer these terms without our written consent. We may assign them, including in a merger, acquisition or sale of assets.
• Force majeure. Neither side is liable for a failure or delay caused by events beyond its reasonable control, including outages of the providers the service runs on, attacks, natural disasters, war, and acts of government. This does not excuse a payment you owe.
• Notices and electronic communication. You agree to receive notices, invoices and agreements electronically. Notices to you are given by email to your account address or in the products; notices to us go to support@stacklumen.com.
• Export and sanctions. You will comply with US and other applicable export control and sanctions laws in using the products.
• Independence. Nothing in these terms makes either of us the partner, agent, employee or joint venturer of the other.
• Language. These terms are written in English, and the English version governs.
