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, including Cloud, which builds and hosts the GitHub repositories you connect), StackIDE (the desktop app for Mac and Windows) and Stacklumen Base (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 and one workspace. 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 and the agency-wide add-ons it buys cover every workspace it holds. A site plan or a per-site add-on is for the one site it is assigned to.

• The agency's owner, and the owners and admins of its first workspace, manage its billing: its plan, its add-ons, its site plans, its payment method and cancelling. 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, shared files or a site to edit, 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.
• A client you invite to edit a site can change only that site's pages and CMS content, as you allow. Every change they make is held until a person at your agency approves it, and what your agency approves and publishes is published by you.
• 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 or Agency, monthly or yearly) and what the agency buys beside it: Stacklumen Base (every component in the library, with more tool runs and designs), sold on its own on any plan; Client payments (invoices and retainers your clients pay by card), on the Agency plan; extra seats and workspaces; a site plan for each site that has one (for a custom domain, Content API keys or pages that show CMS content); and any App routes and Advanced analytics add-ons, each for one site. Paid plans and add-ons are charged in advance, renew automatically until cancelled, and are billed through our payment processor, Stripe. Cloud hosting is paid for separately, from prepaid Cloud credit. Templates are licensed one at a time in the Marketplace and are not part of any plan or add-on. The Pro plan is no longer sold: an agency that holds it keeps it until it moves, as the billing policy sets out. Each agency may take one 14-day trial of the Agency plan, which does not include Stacklumen Base or Client payments. The Billing, Refunds and Chargebacks policy sets out how billing, renewal, price changes, the trial, cancellation, failed payments and taxes work, and it is part of these terms.

Price changes. We may change our prices, and stop selling a plan or an add-on. A change is announced to the agency at least 30 days before it applies to it, applies from a renewal, and never applies to a period you have already paid for.

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, strategies 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.
• Some channels reach beyond your team. What is written in a channel opened to everyone is read by every client's people in the workspace, and what is written in a channel shared with other workspaces is read by the people invited from them. Opening a channel that way, and what you write there, is your choice and your responsibility.

We measure how the products are USED (runs, page views, feature counts). The measuring code does not read what you write, which an explicit column allowlist in the database enforces rather than policy alone. Our staff may open a workspace and view its content, as the Privacy Policy describes.

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. That includes the sites you design and, through Cloud, the sites and apps it builds from the GitHub repositories 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, and a custom domain needs a site plan that includes one. 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.
• A Code site is its GitHub repository. Stacklumen Cloud builds the whole repository and hosts it: on the site's staging address, and, once you connect and prove the site's own domain, directly on that domain, served by the hosting Cloud runs it on rather than through Stacklumen's own servers, with your domain's DNS pointing at that hosting. Its code, the data it keeps and the services it connects to are yours.
• App routes serve a Cloud app, built by Stacklumen Cloud from a GitHub repository you connect, at a route of a Design site. Its code, its data and the services it connects to are yours, and we may stop serving it if it breaks these terms.
• Cloud runs on prepaid Cloud credit, as the Billing, Refunds and Chargebacks policy sets out. When credit runs out and cannot be topped up, Cloud's deploys are paused and taken offline, a Code site's domain included, until credit is added. A deploy that reaches the monthly spending cap set for it is paused until the next month or a higher cap.
• Every Design site we serve counts its own page views. A site that holds Advanced analytics also carries a small script that measures its visits without cookies, as the Privacy Policy and the Data Processing Terms describe. You are responsible for telling your sites' visitors about it, in the site's own privacy notice.
• 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), Cloud building and deploying a repository you connect, fetching assets from a URL, and Stacklumen Base'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, build, deploy, 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.
• Stacklumen only reads a repository you connect: it imports from it, and Cloud builds and deploys what you push to it. It never commits, pushes or opens a pull request. You push with your own git and your own account, and you are responsible for what you push and for what is 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.

StackIDE, the desktop app #

StackIDE is the Stacklumen desktop app for Mac and Windows, under whatever name it installs with. It is part of the service: it signs in with your Stacklumen account and opens the same products you use in the browser, and these terms and the policies they include apply to it as they do to the rest of the products.

• Your licence. While your account is in good standing, we grant you a personal, non-exclusive, non-transferable and revocable licence to install and use StackIDE on computers you own or control, to use the service. It ends when your account closes or your access to the service ends.
• From us only. Install StackIDE only from an installer downloaded from stacklumen.com. A copy obtained anywhere else is not one we provide.
• Updates. StackIDE checks for new versions and may download and install them for you. Updates are part of StackIDE and these terms apply to them. We may stop supporting an older version, and an older version may stop working with the service.
• What you may not do. Apart from installing it on computers you own or control, do not copy, modify, sell, rent, sublicense or redistribute StackIDE, or decompile, disassemble or reverse engineer it, except where the law allows that despite this limit.
• Open-source parts. StackIDE includes open-source software, which is licensed to you under its own licences, whose texts ship with the app. Nothing in these terms limits what those licences allow.
• As is. StackIDE and its updates are provided under the same disclaimers and limits of liability as the rest of the products.

Your computer is yours to look after. StackIDE works on your computer in ways a browser tab cannot. It keeps the folders you choose in step with your sites, writing, replacing and removing site files in them and saving the changes you make there to your site, as edits in the designer are saved. It runs terminals, git, and the commands, scripts and packages your projects use. It starts the coding agents you choose. All of that runs on your computer, under your account and on your instructions, and you are responsible for it, for the security of your computer and for backing up what is on it. StackIDE stays signed in until you sign out, so anybody using a computer where it is signed in acts under your account.

Coding agents are other makers' software. The coding agents StackIDE can start are programs you install yourself and sign in to with your own accounts with their makers. Stacklumen does not provide, bundle, sell or run them or the AI services behind them: they reach their makers' services from your computer, not through Stacklumen, and StackIDE does not read or keep your sign-in details for them. Their makers' terms and privacy policies govern your use of them, and any fees for them are between you and their makers. What an agent does on your computer, in your folders or, through a connection you approve, in your workspace, is done by you, as the Agent and API Terms set out, and we are not responsible for it.

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, and the coding agents you start in StackIDE, 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 Stacklumen Base library. What you build with the library's components and templates is yours. Every account may use the library's free set of components; Stacklumen Base, bought on its own, gives every component; and a template is licensed to one workspace when it is bought, under the Marketplace Terms. What you hold 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 or Stacklumen Base 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.
• While a workspace is suspended, its published sites, its Code sites included, are taken offline, and its keys and agent connections stop, until the suspension is lifted.
• 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.
