Terms of Service

Last updated: July 14, 2026

1. Agreement to these Terms

These Terms of Service (the "Terms") form a legally binding contract between you ("you", "your", or "Customer") and Baselumen, a product operated by Stacklumen Software ("Baselumen", "we", "us", or "our"). They govern your access to and use of the Baselumen website, the component library (across Webflow, React, Figma, and any command-line or sync tooling), your account, any paid subscription, and all related content, features, and services (collectively, the "Service").

By accessing or using the Service — including by browsing the site, creating an account, copying or downloading a component, or purchasing a subscription — you acknowledge that you have read, understood, and agree to be bound by these Terms and by our Privacy Policy, which is incorporated here by reference. If you do not agree to these Terms, you must not access or use the Service.

If you use the Service on behalf of a company, agency, or other organization, you represent that you have authority to bind that entity to these Terms, and "you" refers to that entity.

2. Definitions

• "Components" — the individual UI components, sections, templates, code (HTML, CSS, TypeScript/React), design files, tokens, and related assets made available through the Service.
• "Content" — all text, graphics, code, documentation, and other materials that form part of the Service, excluding your own materials.
• "Subscription" — a paid plan (currently "Starter" and "Premium") that unlocks access to Component source and copy/download features, subject to the applicable usage limits.
• "End Product" — a website, application, or design you build in which Components are incorporated.

3. Eligibility

You must be at least 18 years old, or the age of majority in your jurisdiction, and able to form a binding contract, to use the Service or create an account. You may not use the Service if you are barred from doing so under the laws of your country of residence or any other applicable jurisdiction, or if you are located in, or a national of, any country or region subject to comprehensive sanctions or export restrictions.

4. Accounts and security

Authentication is provided through a third-party identity provider. You are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. You agree to provide accurate information, to keep it current, and to notify us promptly of any unauthorized use or suspected breach. We are not liable for any loss arising from your failure to safeguard your account. You may not share, sell, or transfer your account, and you may not create an account through automated means or on behalf of anyone other than yourself or an entity you are authorized to represent.

5. The Service

Baselumen provides a library of production-oriented UI Components and related tooling. Certain surfaces — such as browsing the library and viewing live previews — are available without charge. Access to Component source, and the ability to copy or download Components, require an active Subscription and are subject to the usage limits described in Section 6. We may add, modify, discontinue, or restrict any part of the Service (including individual Components or features) at any time, with or without notice. We do not guarantee that any particular Component, feature, or integration will remain available.

6. Subscriptions, billing, and payments

6.1 Plans and pricing

Paid Subscriptions are offered on a recurring monthly basis. Current plans and prices are displayed on the Service and may include usage limits (for example, a monthly cap on the number of Components you may copy on the Starter plan, and unlimited copies on the Premium plan). We may change plans, features, usage limits, and prices at any time. Price changes will not apply to your current billing period; continued use after a price change takes effect at your next renewal constitutes acceptance of the new price.

6.2 Payment processing

Payments are processed by our third-party payment processor, Stripe. By subscribing, you authorize us and Stripe to charge your designated payment method for the applicable fees, taxes, and recurring charges. You represent that you are authorized to use the payment method provided. We do not store your full payment card details; those are handled by Stripe under its own terms and privacy policy.

6.3 Auto-renewal

Subscriptions automatically renew at the end of each billing period at the then-current price until cancelled. You authorize recurring charges without further approval until you cancel.

6.4 Cancellation

You may cancel at any time from your account settings or the billing portal. Cancellation takes effect at the end of the current billing period; you retain access to paid features until then, after which your account reverts to the free tier. We do not provide pro-rated refunds for the unused portion of a billing period.

6.5 Refunds

Except where required by applicable law, all fees are non-refundable, and we do not provide refunds or credits for partial periods, unused Components, downgrade, or dissatisfaction. Because Components are digital goods delivered instantly, you acknowledge that you may lose any statutory right of withdrawal once access is provided.

6.6 Taxes

Fees are exclusive of taxes. You are responsible for all applicable sales, use, VAT, GST, and similar taxes, excluding taxes based on our net income.

6.7 Failed payments and chargebacks

If a charge fails, we may suspend or terminate your access to paid features. Initiating a chargeback or payment dispute without first contacting us to resolve the issue is a breach of these Terms and may result in immediate termination and forfeiture of access.

6.8 Marketplace purchases

Where Components or template kits are offered for sale through a third-party marketplace (such as the Webflow Marketplace), those purchases are also governed by that marketplace's terms; in the event of a conflict regarding a marketplace purchase, the marketplace's terms control that transaction.

7. License to use Components

7.1 License grant

Subject to your compliance with these Terms and, where applicable, an active Subscription, we grant you a worldwide, non-exclusive, non-sublicensable, non-transferable license to use, reproduce, modify, and incorporate the Components you access into your own End Products, including unlimited personal and client projects.

7.2 What you may do

• Use Components in unlimited personal and commercial End Products, including projects you build for clients.
• Modify, adapt, restyle, and combine Components, and rebrand the resulting work as your own.
• Keep Components you have incorporated into an End Product even after your Subscription ends — there are no license keys, embed scripts, phone-home calls, or "powered by" attribution requirements for incorporated Components.

7.3 Restrictions

You may not, and may not permit others to:

• Resell, sublicense, redistribute, or make the Components available (in source or substantially unmodified form) as a stand-alone file, template, design kit, or component library, whether free or paid, in a manner that competes with the Service.
• Include Components in any product whose primary purpose is to distribute UI components, templates, or design assets.
• Share your account, Subscription, or Component source with anyone who is not authorized under your Subscription.
• Remove, obscure, or alter any proprietary notices, or misrepresent the origin of the Components.
• Use the Components to train, fine-tune, or develop any machine-learning or generative model, or to build a dataset for such purposes, without our prior written consent.

7.4 Ownership

The license in this Section 7 is a license, not a sale. As between you and us, we (and our licensors) retain all right, title, and interest in and to the Components, the Content, and the Service, including all intellectual property rights. You own the End Products you create, excluding the underlying Components, which remain licensed under these Terms.

8. Acceptable and lawful use

You agree to use the Service only for lawful purposes and in accordance with these Terms. You are solely responsible for ensuring that your use of the Service and your End Products comply with all applicable laws, regulations, and third-party rights. Without limiting the foregoing, you agree that you will not, and will not enable or permit any third party to:

• Use the Service in violation of any applicable local, national, or international law or regulation, including data-protection, consumer-protection, export-control, and sanctions laws.
• Use the Components or the Service to create, host, or distribute content or applications that are unlawful, infringing, defamatory, obscene, harassing, hateful, deceptive, or that promote illegal activity, violence, or discrimination.
• Infringe, misappropriate, or violate the intellectual-property, privacy, publicity, or other rights of any person or entity.
• Upload or transmit any malware, virus, or malicious code, or use the Service to engage in phishing, fraud, spamming, or any deceptive or predatory practice.
• Attempt to gain unauthorized access to, interfere with, degrade, or disrupt the Service, its infrastructure, other users, or any connected system or network; or circumvent, disable, or bypass any authentication, paywall, usage limit, rate limit, or security or access-control measure.
• Scrape, crawl, harvest, mine, or use automated means to access, index, or extract the Service or the Components beyond what is expressly permitted, or copy Components other than through the features provided.
• Reverse engineer, decompile, or disassemble any non-public part of the Service, or probe, scan, or test its vulnerability, except to the extent this restriction is prohibited by applicable law.
• Resell, sublicense, or commercially exploit the Service or the Components except as expressly permitted in Section 7.
• Use the Service to build a product or service that competes with Baselumen, or for any benchmarking or competitive-analysis purpose intended to develop a competing offering.
• Misuse the Service in any way that could damage, disable, overburden, or impair it, or that violates the rights of, or restricts or inhibits the use and enjoyment of the Service by, any other party.

We reserve the right, but have no obligation, to investigate and to take appropriate action — including removing content, limiting or suspending features, and suspending or terminating accounts, with or without notice — against any user who, in our sole judgment, violates this Section 8 or any other provision of these Terms, or whose conduct we determine may expose us or others to liability. We may also report suspected unlawful activity to law-enforcement or regulatory authorities and cooperate with any resulting investigation.

9. User submissions and feedback

If you submit content to us (for example, through a form, support request, or review) or provide suggestions, ideas, or feedback about the Service ("Feedback"), you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use, reproduce, modify, and incorporate that content and Feedback for any purpose, including improving and marketing the Service, without any obligation or compensation to you. You represent that you have all necessary rights to grant this license and that your submissions do not violate these Terms or any third-party rights.

10. Intellectual property, copyright, and authorship

10.1 Copyright and authorship

The Components and Content are original works of authorship created and owned by Baselumen and Stacklumen Software, and are protected by copyright and other intellectual-property laws worldwide. We are, and are entitled to be identified as, the author and copyright owner of the Components and Content. All rights are reserved except for the limited license expressly granted to you in Section 7. No title to, or ownership of, any Component or Content is transferred to you under these Terms; you receive only the rights the license grants.

10.2 Trademarks and brand

The "Baselumen" and "Stacklumen" names, logos, marks, and the look and feel of the Service are our trademarks and trade dress. You may not use, register, or imitate them, or any confusingly similar mark, without our prior written permission.

10.3 Permitted commercial use; prohibited resale

For clarity, and notwithstanding anything else: you may use the Components in commercial projects and in unlimited client work, including projects for which you are paid. However, you may not use, package, distribute, or sell the Components — in whole or in substantial part, in source or substantially unmodified form — as, or as part of, a component library, template, UI kit, design system, boilerplate, or any other product or offering whose purpose is to distribute or resell UI components or design assets, whether free or paid. You may not present the Components, or derivatives that do not represent genuine, substantial creative work of your own, as your own product for redistribution. These protections survive termination.

10.4 Reservation of rights

Any use of the Components or Content not expressly permitted by these Terms is a breach and an infringement of our rights. We reserve all rights and remedies available at law and in equity, including injunctive relief, to protect our copyright, authorship, and other rights.

11. Third-party services and links

The Service integrates with, and may link to, third-party services — including our identity provider (authentication), Stripe (payments), our database and hosting providers, our email/marketing provider, and platforms such as Webflow, Figma, and content delivery networks. Your use of those third-party services is governed by their own terms and privacy policies, and we are not responsible or liable for them. Third-party links and integrations are provided for convenience and do not imply endorsement. See our Legal overview and Privacy Policy for how information is handled across these services.

12. Copyright and takedown

We respect intellectual-property rights. If you believe that content available through the Service infringes your copyright or other rights, please contact us at apps@stacklumen.com with (a) a description of the work you claim is infringed, (b) the location of the allegedly infringing material, (c) your contact information, (d) a statement that you have a good-faith belief the use is not authorized, and (e) a statement, under penalty of perjury, that the information is accurate and that you are the rights holder or authorized to act on their behalf. We may remove allegedly infringing material and terminate repeat infringers.

13. Disclaimers of warranties

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE, THE COMPONENTS, AND ALL CONTENT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. WE EXPRESSLY DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, ACCURACY, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT: (a) THE SERVICE OR COMPONENTS WILL MEET YOUR REQUIREMENTS OR BE COMPATIBLE WITH YOUR SYSTEMS, FRAMEWORKS, OR END PRODUCTS; (b) THE SERVICE WILL BE UNINTERRUPTED, SECURE, TIMELY, OR ERROR-FREE; (c) ANY DEFECTS WILL BE CORRECTED; (d) THE COMPONENTS WILL BE FREE OF BUGS, VULNERABILITIES, OR HARMFUL CODE; OR (e) THE COMPONENTS WILL BE ACCESSIBLE, COMPLIANT, OR SUITABLE FOR ANY PARTICULAR LEGAL, REGULATORY, OR ACCESSIBILITY STANDARD. YOU ARE SOLELY RESPONSIBLE FOR TESTING, REVIEWING, AND VALIDATING ANY COMPONENT BEFORE USING IT IN AN END PRODUCT AND FOR THE END PRODUCTS YOU BUILD. ANY MATERIAL OBTAINED THROUGH THE SERVICE IS ACCESSED AT YOUR OWN RISK.

SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU. IN THAT CASE, SUCH WARRANTIES ARE LIMITED TO THE MINIMUM SCOPE AND DURATION PERMITTED BY LAW.

14. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

14.1 Exclusion of indirect damages. IN NO EVENT WILL BASELUMEN, STACKLUMEN SOFTWARE, OR THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, AGENTS, SUPPLIERS, OR LICENSORS (THE "BASELUMEN PARTIES") BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES; OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, BUSINESS, ANTICIPATED SAVINGS, DATA, OR USE; OR FOR BUSINESS INTERRUPTION OR THE COST OF SUBSTITUTE PRODUCTS OR SERVICES — ARISING OUT OF OR RELATING TO THESE TERMS, THE SERVICE, OR THE COMPONENTS, WHETHER BASED ON CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL THEORY, AND WHETHER OR NOT THE BASELUMEN PARTIES HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND EVEN IF A REMEDY FAILS OF ITS ESSENTIAL PURPOSE.

14.2 Liability cap. THE TOTAL AGGREGATE LIABILITY OF THE BASELUMEN PARTIES FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS, THE SERVICE, OR THE COMPONENTS WILL NOT EXCEED THE GREATER OF (a) THE TOTAL AMOUNTS YOU ACTUALLY PAID TO US FOR THE SERVICE IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE CLAIM, OR (b) ONE HUNDRED U.S. DOLLARS (US$100). THIS CAP IS CUMULATIVE AND NOT PER-INCIDENT; MULTIPLE CLAIMS DO NOT ENLARGE IT.

14.3 End Products. THE BASELUMEN PARTIES HAVE NO LIABILITY WHATSOEVER FOR YOUR END PRODUCTS, INCLUDING ANY CLAIM THAT A COMPONENT, AS INCORPORATED OR MODIFIED BY YOU, INFRINGES A THIRD PARTY'S RIGHTS, FAILS TO MEET A LEGAL OR ACCESSIBILITY STANDARD, OR CAUSES HARM. YOU ASSUME FULL RESPONSIBILITY FOR YOUR END PRODUCTS AND YOUR CLIENTS.

14.4 Basis of the bargain. THE LIMITATIONS AND EXCLUSIONS IN THIS SECTION 14 AND IN SECTION 13 ARE A FUNDAMENTAL BASIS OF THE BARGAIN BETWEEN YOU AND US AND REFLECT A REASONABLE ALLOCATION OF RISK; THE SERVICE WOULD NOT BE PROVIDED WITHOUT THEM. THEY APPLY TO THE FULLEST EXTENT PERMITTED BY LAW.

14.5 Jurisdictional limits. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU. NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT BE EXCLUDED OR LIMITED UNDER APPLICABLE LAW, SUCH AS LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, OR FOR FRAUD. IN SUCH JURISDICTIONS, OUR LIABILITY IS LIMITED TO THE GREATEST EXTENT PERMITTED BY LAW.

15. Indemnification

You agree to defend, indemnify, and hold harmless the Baselumen Parties from and against any and all claims, demands, actions, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use or misuse of the Service or the Components; (b) your End Products; (c) your violation of these Terms or of any law or third-party right; or (d) any content or materials you submit. We reserve the right, at our own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, in which case you agree to cooperate with our defense.

16. Term and termination

These Terms apply while you use the Service. You may stop using the Service at any time and may cancel a Subscription as described in Section 6. We may suspend or terminate your access to all or part of the Service at any time, with or without notice or cause, including if we believe you have violated these Terms, to protect the Service or other users, or to comply with law. Upon termination, your license to access Component source ceases, but Section 7's rights to Components already incorporated into your End Products survive, and Sections 6.5, 7.4, 9, 10, 13, 14, 15, 17, and 18–20 survive termination.

17. Governing law and dispute resolution

These Terms are governed by the laws of the State of [STATE], United States, without regard to its conflict-of-laws rules, except that the application of any local law that would require the application of a different jurisdiction's law is expressly excluded. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Informal resolution. Before filing a claim, you agree to try to resolve the dispute informally by contacting us at apps@stacklumen.com; we will try to resolve it with you in good faith for at least thirty (30) days.

Venue. Subject to any applicable arbitration or small-claims option, you and we agree to the exclusive jurisdiction of, and venue in, the state and federal courts located in [COUNTY, STATE] for any dispute not subject to arbitration, and you waive any objection to that venue.

Class-action waiver. To the extent permitted by law, disputes will be resolved on an individual basis only, and you waive any right to participate in a class, consolidated, or representative action.

Time limit. Any claim arising out of or relating to these Terms or the Service must be filed within one (1) year after the claim arose; otherwise it is permanently barred, except where a longer period is required by applicable law.

Note: bracketed items above must be completed with the operator's chosen jurisdiction.

18. Changes to the Service and these Terms

We may modify these Terms at any time. When we do, we will update the "Last updated" date and, for material changes, provide reasonable notice — for example, through the changelog, an in-product notice, or email. Changes are effective when posted unless stated otherwise. Your continued use of the Service after changes take effect constitutes acceptance of the revised Terms. If you do not agree, you must stop using the Service. We may also change, suspend, or discontinue any part of the Service as described in Section 5.

19. General

• Entire agreement. These Terms, together with the Privacy Policy and any plan-specific terms, are the entire agreement between you and us regarding the Service and supersede any prior agreements.
• Severability. If any provision is held unenforceable, it will be modified to the minimum extent necessary, and the remaining provisions will remain in full force.
• No waiver. Our failure to enforce any provision is not a waiver of it.
• Assignment. You may not assign these Terms without our prior written consent; we may assign them freely, including in connection with a merger, acquisition, or sale of assets.
• Force majeure. We are not liable for any delay or failure to perform caused by events beyond our reasonable control.
• Notices. We may provide notices to you by email, through the Service, or by posting on the site.
• Relationship. Nothing in these Terms creates any partnership, joint venture, agency, or employment relationship between you and us.
