These Terms of Service (“Terms”) govern your access to and use of PlanGrounds, a marketplace and workflow platform that helps clients discover plans, post projects, and connect with design professionals. PlanGrounds is operated by Polygen Lab LLC (“PlanGrounds,” “we,” “us,” or “our”) - the operating entity that may appear on billing, receipts, and legal notices. By accessing or using PlanGrounds, creating an account, posting content, purchasing plans, funding milestones, or otherwise using the platform, you agree to these Terms. If you do not agree, do not use PlanGrounds.
You accept these Terms by using the platform or by completing any in-product acceptance (for example at onboarding). If you use PlanGrounds on behalf of an organization, you represent that you have authority to bind that organization, and “you” includes that organization. We may require re-acceptance when we publish a new terms version.
You must be at least 18 years old (or the age of majority where you live) and able to form a binding contract. You must provide accurate registration information, keep credentials secure, and promptly update account details. You are responsible for activity under your account. Professionals who offer services must have (and maintain) any licenses, registrations, insurance, or other credentials required for the work they advertise or perform. We may refuse, suspend, or limit accounts where we reasonably believe eligibility, accuracy, or security is compromised.
PlanGrounds provides software for listings, messaging, proposals, contracts tooling, checkout, payment facilitation, and related records. Professionals listed or hired through PlanGrounds are independent third parties - not employees, partners, agents, or joint venturers of Polygen Lab LLC. They control their own services, pricing, timelines, staffing, and deliverables. PlanGrounds is not an architecture firm, engineering firm, contractor, or professional services provider; does not practice architecture or engineering; does not stamp or seal drawings; does not supervise professionals; and does not endorse, warrant, or guarantee any professional, listing, plan, proposal, estimate, schedule, or outcome. Appearance on the platform is not a recommendation or certification of quality, licensure status, or fitness for your project.
When a client hires a professional, the engagement is solely between those parties (plus any written agreement they adopt). PlanGrounds is not a party to that professional engagement except to the limited extent of providing platform features and payment mechanics described in these Terms. You are solely responsible for your own due diligence: verifying identity and credentials, confirming licensure and scope of practice in the relevant jurisdiction, negotiating scope, schedule, fees, insurance, and contract terms, and deciding whether to proceed.
Listings, plan packages, descriptions, estimates, tools, AI-assisted outputs, guides, and other information on PlanGrounds are for convenience and marketplace facilitation only. They are not professional advice and are not a substitute for licensed architecture, engineering, surveying, geotechnical, legal, tax, or permitting services, or for local code review. PlanGrounds does not review, stamp, seal, certify, or warrant plans, drawings, or documents for code compliance, constructability, structural adequacy, site fitness, or permitability. Always engage qualified local professionals and your authority having jurisdiction for your specific project.
You agree to: (a) provide accurate, current, and complete information in profiles, listings, proposals, invoices, and communications; (b) comply with all applicable laws, licensing rules, export controls, and tax obligations; (c) only upload and sell content you have rights to provide; (d) honor agreements and deliverables you commit to through the platform; (e) not misrepresent credentials, experience, ownership of plans, or project status; and (f) for professionals, perform independent licensure and competence diligence before offering services in a jurisdiction. Clients remain responsible for confirming that purchased or commissioned work meets their permit and construction needs.
You may not: engage in fraud, money laundering, or payment abuse (including unjustified chargebacks); steal, scrape, crawl, harvest, or reverse-engineer platform content or user data beyond ordinary use; infringe intellectual property or privacy rights; upload malware or interfere with platform security or availability; harass, threaten, or discriminate; post unlawful, deceptive, or defamatory content; circumvent platform fees or payment flows by steering users to off-platform payment for engagements that began on PlanGrounds where our product requires or offers on-platform payment; create fake accounts or manipulate reviews, rankings, or proposals; or assist others in doing any of the above. We may investigate and take action for suspected violations.
PlanGrounds, including its software, branding, layout, and original platform materials, is owned by Polygen Lab LLC or its licensors. You receive a limited, non-exclusive, non-transferable, revocable license to use the platform as permitted by these Terms. You retain ownership of content you upload (plans, drawings, text, images, and similar “User Content”), subject to rights you grant others. By posting or selling User Content, you grant PlanGrounds a worldwide, non-exclusive license to host, display, reproduce, distribute, and otherwise use that content as needed to operate, promote, and improve the marketplace (including thumbnails, search, and transactional delivery). You represent that you have all rights needed to grant this license and to sell or license the content to buyers under the listing terms. Purchasers receive only the rights described in the listing, checkout terms, and any separate license from the seller - not ownership of PlanGrounds platform IP.
Paid features show price and fees at purchase or acceptance. Marketing pages may summarize illustrative fee ranges on Pricing. For legal and billing purposes, the amount shown in the product at checkout or acceptance - and any separate written agreement with Polygen Lab LLC that expressly addresses fees - controls over marketing summaries. Payments may be processed by Stripe or similar providers under their terms. On plan purchases and milestone funding, the platform fee (a percentage of the service amount) is shown as a separate checkout line paid by the client on top of the service amount; estimated card-processing costs may appear as an additional pass-through line so they are not deducted from the platform percentage. The professional receives the service amount transferred. Fees are disclosed before confirmation. You are responsible for applicable taxes unless we expressly collect them. Chargebacks, payment disputes with card networks, and refund requests are handled under the terms shown at purchase, our payments and risk policies, processor rules, and applicable law. Initiating a chargeback in bad faith or to avoid paying for delivered work is prohibited and may result in suspension and recovery of fees, costs, and amounts owed.
Where the product supports milestone or staged payments, clients may authorize or fund amounts that are captured and/or released according to the workflow shown in the product (for example upon client approval or contractual triggers). These mechanics are payment facilitation through licensed payment partners - not a bank account, trust, or licensed escrow service in your name, and not a guarantee of work quality. Approving a milestone or confirming delivery is your user action; it is not PlanGrounds’ determination that work is adequate for permitting or construction. Change orders and scope changes are between client and professional unless sold or recorded through the platform under terms shown at that time. Additional operational detail may appear in our payments and risk policy; these Terms control if there is a conflict.
Plan packages, drawings, PDFs, models, and other deliverables are provided by the selling or hired professional (or as described in the listing). PlanGrounds does not review, stamp, seal, or certify plans for code compliance, constructability, or fitness for your site. What a purchase or engagement includes - file types, license scope, revision rounds, schedule, and exclusions - is defined by the listing, checkout description, in-product contract or change-order terms, and any separate agreement between you and the professional. Sellers are responsible for accurate listings and for delivering what they sold.
Where the product allows you to approve, accept, or fund a milestone, that action reflects your confirmation as a user (for example that a described deliverable was made available), not a determination by PlanGrounds that the work is adequate for permitting or construction. Extra revisions, resubmittals, or scope changes are between client and professional unless expressly sold through the platform.
Disputes about design quality, completeness, schedule, suitability, licensure, or contract performance must be resolved primarily between the client and the professional. PlanGrounds may offer messaging, optional dispute or refund tooling, or limited administrative support as a convenience, but we are not a party to the users’ professional agreement and do not become an arbitrator, insurer, or guarantor by providing those tools.
PlanGrounds is not obligated to mediate design quality, completeness of drawings, or suitability for a specific jurisdiction. Any optional dispute or refund workflow on the platform is administrative convenience only and does not make PlanGrounds the guarantor of professional services or the insurer of project outcomes.
We may suspend, restrict, or terminate access, remove listings or content, withhold or reverse payouts where permitted by law and processor rules, and refuse service if you violate these Terms, create risk of fraud or legal exposure, attempt prohibited off-platform payment circumvention, abuse chargebacks, scrape or attack the platform, or otherwise misuse the marketplace. You may stop using PlanGrounds at any time. Provisions that by nature should survive (including IP ownership, licenses already granted as needed for completed transactions, indemnity, disclaimers, limitation of liability, and governing law) survive termination.
To the maximum extent permitted by law, you agree to defend, indemnify, and hold harmless Polygen Lab LLC, PlanGrounds, and their officers, directors, employees, agents, and affiliates from and against any claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your User Content, listings, plans, or professional services; (b) your breach of these Terms or applicable law; (c) your negligence or willful misconduct; (d) disputes between you and other users or third parties; (e) alleged infringement or misappropriation of IP or privacy rights by you; or (f) your use of information or deliverables obtained through the platform. We may assume exclusive defense of any matter subject to indemnity; you will cooperate. This does not limit any non-waivable rights you may have under applicable law.
To the fullest extent permitted by law, PlanGrounds and Polygen Lab LLC are not liable for any indirect, incidental, special, consequential, exemplary, or punitive damages; for lost profits, revenue, data, or goodwill; or for losses arising from engagements, plans, advice, or deliverables between users - even if advised of the possibility. To the fullest extent permitted by law, our aggregate liability for any claim arising out of or relating to the platform or these Terms is limited to the greater of (i) the amounts you actually paid to PlanGrounds (platform fees or amounts payable to us, not amounts merely facilitated to other users) in the twelve (12) months before the event giving rise to the claim, or (ii) if you paid PlanGrounds nothing in that window - for example you only browsed or messaged for free - one hundred U.S. dollars ($100). That $100 figure is not a fee we charge; it is a contractual liability ceiling for unpaid users unless applicable law requires otherwise. Some jurisdictions do not allow certain limitations; in those cases our liability is limited to the maximum extent permitted. Nothing in these Terms excludes liability that cannot be excluded by law.
THE PLATFORM IS PROVIDED “AS IS” AND “AS AVAILABLE.” TO THE MAXIMUM EXTENT PERMITTED BY LAW, POLYGEN LAB LLC AND PLANGROUNDS DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE. WE DO NOT WARRANT THAT THE PLATFORM WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, OR THAT LISTINGS, PLANS, PROPOSALS, OR USER CONTENT WILL MEET YOUR REQUIREMENTS OR BE ACCURATE OR RELIABLE. YOU USE THE PLATFORM AND RELY ON USER CONTENT AND PROFESSIONALS AT YOUR OWN RISK.
Our collection and use of personal information is described in our Privacy Policy, which is incorporated by reference. By using PlanGrounds you acknowledge that policy.
These Terms are governed by the laws of the State of Colorado, United States, without regard to conflict-of-law rules that would require another jurisdiction’s law. Except where prohibited by applicable law (including any non-waivable consumer protections), exclusive venue for disputes arising out of or relating to these Terms or the platform lies in the state or federal courts located in Colorado, and you consent to personal jurisdiction there. Mandatory consumer rights in your place of residence are not displaced where they cannot be waived.
We may update these Terms by posting a revised version and updating the “Last updated” date. Material changes may also be communicated in-product or by email when appropriate. Continued use after the effective date constitutes acceptance of the revised Terms, except where applicable law requires a different method of consent. If any provision is held unenforceable, the remainder remains in effect. These Terms, together with the Privacy Policy, any in-product payment disclosures, and any separate written agreement with Polygen Lab LLC that expressly modifies them, are the entire agreement between you and us regarding the platform and supersede prior conflicting statements on the same subject. Failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a reorganization, merger, or sale of assets.
