Linimo — Terms of Service

Version 1.0 · Effective Date: September 29, 2026

These Terms of Service ("Terms") are an agreement between you and ARCH-CORE LAB, LLC, an Illinois limited liability company ("ARCH-CORE LAB," "we," "us" or "our"). They govern your use of Linimo — our web application, shared-document viewer, desktop application, account site, and related online services (the "Service").

Our handling of personal information is described in the Linimo Privacy Policy. If you use the Linimo desktop application, its End User License Agreement ("EULA") also applies; if these Terms and the EULA conflict on a matter about the desktop software, the EULA controls, and otherwise these Terms control.

You accept these Terms by checking the acceptance box when you create your account or subscribe. Please read Section 17 (Disputes) carefully: it requires disputes to be decided individually in the courts of Cook County, Illinois, and includes a waiver of jury trial and class actions to the extent the law allows.

1. Your Account

1.1 Eligibility

You must be at least 18 years old, or the age of majority where you live, and able to form a binding contract. If you use the Service for a company or other organization, you confirm that you have authority to accept these Terms for it, and "you" includes that organization.

1.2 Your account

Give us accurate information and keep it up to date. Keep your password confidential and don't share your account. You are responsible for activity under your account unless it results from our failure to meet our obligations under these Terms. Tell us promptly at support@archcorelab.com if you suspect unauthorized use.

1.3 Team accounts

On a team plan, the team's owner or administrators control seats, members and billing. Team members use the Service on the organization's behalf, and administrators can manage their access. Each seat is for one named person and may not be shared.

2. Plans, Trials and Payment

2.1 Plans

Linimo offers a free Lite plan and paid plans, including individual Pro and Pro Plus plans and Team plans billed per seat. Features and current prices are shown at linimo.app/pricing. Team pricing depends on the number of seats and the billing interval. We may change the features included in the free plan at any time.

2.2 Free trial

New accounts may receive a free trial of a paid plan. No payment method is needed, and the trial never turns into a paid subscription automatically. When it ends, your account continues on the Lite plan unless you choose to subscribe.

2.3 Automatic renewal

Paid subscriptions renew automatically at the end of each billing period (monthly or annually) at the then-current price, and we charge your payment method until you cancel. Before you subscribe, we show you the price, the billing interval and how to cancel, and we ask for your agreement to automatic renewal. We confirm your subscription by email. For annual plans, we email you a reminder 30 to 45 days before each renewal, with the renewal date, the price and how to cancel.

2.4 Payment

Fees are billed in advance in U.S. dollars. Payments are processed by Stripe, and by subscribing you also agree to Stripe's terms. Prices do not include taxes, and you are responsible for any taxes that apply.

2.5 Price changes

We will tell you about a price increase at least 30 days before it applies to you, by email and in the Service. The new price applies from your next renewal. If you don't want to continue at the new price, cancel before the renewal date.

2.6 Failed payments

If a renewal payment fails, we will email you and retry the charge. You keep full access to your paid plan for 7 days while you update your payment method. If payment still hasn't succeeded after 7 days, your subscription is cancelled and your account moves to the Lite plan. Your content is not deleted because of a failed payment.

2.7 Cancellation and no refunds

You can cancel at any time in your account settings, under Billing. When you cancel, you keep access to your paid plan until the end of the billing period you have already paid for; your subscription then ends and your account moves to the Lite plan. Cancellation takes effect online immediately — no email or call is needed.

Fees are non-refundable. We don't provide refunds or credits for partial billing periods, unused features or seats, or a downgrade, except where the law requires them.

2.8 Plan changes

If you upgrade, the higher plan starts right away and you are charged the prorated difference for the rest of your current billing period, as shown before you confirm. If you downgrade, the change takes effect at the end of your current billing period.

2.9 Promotional and lifetime plans

We may offer promotional plans on terms stated when offered. A "lifetime" plan lasts for as long as we offer the Service, is personal to you, and cannot be transferred.

3. Your Content

3.1 You own your content

"Your Content" means the files, drawings, markups, measurements, notes, templates and other material you create, upload, import or share with the Service, including drawings you generate with it. You keep all rights to Your Content.

3.2 The permission you give us

You give ARCH-CORE LAB a worldwide, non-exclusive, royalty-free license to host, store, copy, process, transmit and display Your Content, and to make technical changes to it (such as merging collaborators' markups, converting formats and extracting title-block text), solely to provide, secure and support the Service for you and the people you share with. Our service providers may exercise this license only on our behalf. The license ends when Your Content is deleted from the Service, except for copies in backups that are deleted on their normal schedule.

We will not use Your Content for marketing, sell it, or grant anyone broader rights than you have given us.

3.3 AI and machine learning

We do not use Your Content to train artificial-intelligence or machine-learning models. If we ever offer a feature that would use Your Content this way, we will ask for your separate, opt-in consent first, and you can withdraw it at any time.

3.4 Your responsibilities

You confirm that you have the rights you need to upload, use and share Your Content, and that doing so does not violate the law or anyone else's rights, including copyright in drawings created by others.

3.5 Feedback

If you send us ideas or suggestions, we may use them without obligation to you.

4. Sharing and Collaboration

You decide what to share and with whom. When you invite collaborators to a document or project, or turn on a view link, we make the shared content available to those people according to the permissions you choose. Anyone who has a view link can open the shared document, including the PDF, until you turn the link off or it expires. View links expire after 30 days unless you extend them.

You are responsible for the people you invite and the links you create, including if they share them further. Removing a collaborator or turning off a link stops future access through the Service, but cannot recall copies people have already downloaded. Sharing does not transfer ownership of Your Content.

People who open a view link without a Linimo account are not bound by these Terms; you remain responsible for sharing with them.

5. Connected Services

You can connect third-party services such as Google Drive and Microsoft OneDrive. By connecting one, you authorize us to access and exchange data with it on your behalf as needed for the features you use — for example, to open and save your files, share folders you choose, and write collaborators' changes back to documents you have shared.

Connected services are not part of the Service. They are provided under their own terms, may change or stop working, and are not our responsibility. Microsoft Corporation and Google LLC are not parties to these Terms and have no liability to you under them.

6. Professional Use of Linimo

Linimo is a tool for reviewing, marking up and sketching drawings. It does not provide architectural, engineering, surveying, estimating, code-consulting or legal services, and it is not a substitute for the judgment of a qualified, licensed professional.

6.1 Measurements

Lengths, areas, perimeters, counts and other quantities are calculated from the drawing scale you select and the geometry of the source file. Their reliability depends on that scale being correct and on the source drawing having been drawn and reproduced to scale; scanned, resized, rasterized or "not to scale" documents can give incorrect results. The displayed precision (decimal places or fractions) is a formatting setting, not a measure of accuracy. Written dimensions and the contract documents of record always govern over any dimension scaled or measured in Linimo. Verify measurements, and field conditions, before relying on them for bidding, estimating, procurement, fabrication, permitting or construction.

6.2 Symbol library and concept sketches

The symbol library (doors, windows, fixtures, furniture and other objects) and the drawings and concept sketches you create or generate with Linimo are drafting aids for representation and concept design only. They show typical sizes and configurations. They are not designed to satisfy, and are not represented as complying with, accessibility requirements — including the ADA Standards for Accessible Design, ICC A117.1 and the Fair Housing Act design requirements — or any building, residential, fire, plumbing, energy, zoning or other code as adopted in your jurisdiction.

You, and the licensed professional responsible for your project, are solely responsible for determining which codes and standards apply and for designing, detailing and verifying compliance. We do not review drawings for compliance.

You may use library symbols in your drawings and share those drawings, but you may not distribute the symbol library itself.

6.3 Automated features

Title-block text recognition (OCR), tracing and other automated features are provided for convenience. Their results may be incomplete or wrong. Check them against the source before relying on them.

6.4 Not a system of record

Linimo is not a records-retention or archival system. Keep your own authoritative records and copies of your project documents (see Section 11).

7. Using the Service

7.1 Your right to use the Service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable right to access and use the Service for your internal business or professional purposes, with the features of your plan, while your account is in good standing. We and our licensors own the Service, including its software, design and symbol library. All rights not expressly granted are reserved.

7.2 Acceptable use

You agree not to:

copy, modify or create derivative works of the Service, or decompile, disassemble or reverse engineer it, except to the extent applicable law expressly permits this despite this restriction;
remove or alter any proprietary, copyright or trademark notices;

break the law, or infringe or misappropriate anyone's intellectual property or other rights;
upload malware, or probe, scan or test the vulnerability of the Service or bypass its security (report security issues to security@archcorelab.com instead);
interfere with or overload the Service, or use bots, scrapers or other automated means to access it except through features we provide;
circumvent plan limits, feature restrictions, seat limits or other technical measures, or share an account or seat;
resell or provide the Service to others as a service, or use it to build a competing product;
use the Service or its outputs to train AI or machine-learning models, or extract the symbol library in bulk;
use view links or sharing to distribute content you don't have the right to share; or
harass or harm others, impersonate anyone, or send spam.

8. Export Controls and Sanctions

(a) The Service is subject to U.S. export control and economic sanctions laws, including regulations administered by the U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) and the U.S. Department of Commerce.

(b) You represent and agree that you are not, and are not acting on behalf of, (i) any person or entity located, organized or ordinarily resident in a country or region subject to comprehensive U.S. sanctions; (ii) any person or entity on, or owned 50% or more by persons on, a U.S. government restricted-party list, including OFAC's Specially Designated Nationals and Blocked Persons List; or (iii) any person otherwise prohibited from receiving the Service under U.S. law.

(c) You will not access or use the Service from, or allow anyone to access or use it from, any such country or region, and you will not export, re-export or transfer any part of the Service or Your Content in violation of these laws.

(d) We may, without liability, block access from locations we believe are restricted, refuse or cancel any account or payment, and suspend or terminate your access immediately if we believe you have breached this Section or that providing the Service to you would violate the law. Fees for an account terminated under this Section are not refundable, except where the law requires a refund.

(e) We may restrict access from other countries or regions at our discretion, even where the law does not require it.

9. Copyright Complaints

We respect intellectual property rights and respond to notices of alleged infringement under the Digital Millennium Copyright Act (DMCA).

Designated agent: DMCA Agent, ARCH-CORE LAB, LLC, 111 W Jackson Blvd, Suite 1700, Chicago, IL 60604 · dmca@archcorelab.com

Notices must include: (1) your physical or electronic signature; (2) identification of the copyrighted work; (3) identification of the material you claim is infringing and enough information for us to find it, such as the view-link address; (4) your name, address, telephone number and email; (5) a statement that you believe in good faith that the use is not authorized by the copyright owner, its agent or the law; and (6) a statement, under penalty of perjury, that the information is accurate and that you are the owner or authorized to act for the owner.

Counter-notices. If your content was removed and you believe that was a mistake, you may send a counter-notice including: (1) your physical or electronic signature; (2) identification of the removed material and where it appeared; (3) a statement under penalty of perjury that you believe in good faith it was removed by mistake or misidentification; and (4) your name, address and telephone number, and a statement that you consent to the jurisdiction of the federal district court for your address (or, if outside the United States, any district where we may be found) and will accept service from the person who sent the notice. Unless the complainant tells us they have filed a lawsuit, we may restore the material 10 to 14 business days after receiving a valid counter-notice.

Knowingly false notices or counter-notices can create liability. We terminate, in appropriate circumstances, the accounts of users who are repeat infringers.

10. Support and Availability

10.1 Support

We provide best-effort support by email at support@archcorelab.com. We don't guarantee response times.

10.2 Availability

The Service is provided "as is" and "as available." We don't offer a service-level agreement or uptime commitment unless we agree to one in a signed order. The Service depends on third-party hosting, cloud, identity, storage and network providers, and on your own internet connection and devices. We are not liable for delays, interruptions, unavailability of data, or failures caused by those providers; by Google Drive, Microsoft OneDrive or other services you connect (including changes to their programming interfaces, permissions or availability); or by other causes beyond our reasonable control, including failure of the internet, power or telecommunications, attacks on third parties, acts of government, natural disasters, epidemics, war or labor disputes.

10.3 Changes to the Service

We may add, change or remove features. If we make a change that materially reduces the core functionality of a paid plan during your current billing period, we will tell you in advance.

11. Your Copies and Data Export

Online services can suffer outages, errors and data loss. You are responsible for keeping your own backup copies of Your Content, including the source files you store in Google Drive, OneDrive or elsewhere. We take reasonable steps to protect stored data, but we don't guarantee that Your Content will be kept without loss or corruption.

You can export your work at any time in PDF, PNG, JPEG, DXF, CSV and .lno formats. Your .lno files remain usable on the free Lite plan after a paid subscription ends.

12. Suspension and Termination

12.1 By you

You can cancel your subscription at any time (Section 2.7) and close your account in your account settings.

12.2 By us

We may suspend or terminate your access if you materially breach these Terms (or the EULA, for the desktop application), if your use creates a security risk or legal liability for us or harms other users, if required by law, or if your subscription is cancelled for non-payment (in which case your account moves to the Lite plan). We will give you notice when we reasonably can. We may also end the Service or your account for convenience with at least 30 days' notice. If we do this for convenience during a paid billing period, you keep access until the end of that period.

12.3 After your account closes

If you close your account while a paid subscription is active, the subscription does not renew and your account stays open until the end of the period you have paid for; it closes then. When your account closes, your access ends, including any license to the desktop application. You have 30 days to export Your Content. After that, we delete it as described in the Privacy Policy. Files you saved to your own device or cloud storage are not affected. Sections 3.2 (for backup copies), 3.4, 3.5, 6, 8, 11 and 13 through 19 survive.

13. Disclaimer of Warranties

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE, THE SOFTWARE AND ALL OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS. ARCH-CORE LAB, ON BEHALF OF ITSELF AND ITS SUPPLIERS AND LICENSORS, DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT AND ACCURACY, AND ANY WARRANTY THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE OR ERROR-FREE, THAT CONTENT WILL BE PRESERVED WITHOUT LOSS, OR THAT MEASUREMENTS, CALCULATIONS, TEXT RECOGNITION, TRACED OR GENERATED DRAWINGS WILL BE ACCURATE, COMPLETE OR COMPLIANT WITH ANY CODE OR STANDARD.

14. Limitation of Liability

14.1 Excluded damages. TO THE MAXIMUM EXTENT PERMITTED BY LAW, ARCH-CORE LAB WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, BIDS OR BUSINESS OPPORTUNITIES; DELAY, REWORK OR CONSTRUCTION COSTS; OR LOSS, CORRUPTION OR UNAVAILABILITY OF DATA, ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS, EVEN IF WE WERE ADVISED OF THE POSSIBILITY OF THOSE DAMAGES.

14.2 Cap. TO THE MAXIMUM EXTENT PERMITTED BY LAW, ARCH-CORE LAB'S TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) US $1,000. IF YOU USE ONLY THE FREE LITE PLAN AND HAVE PAID US NOTHING, OUR TOTAL LIABILITY WILL NOT EXCEED US $100.

14.3 What these limits don't cover. Nothing in these Terms limits liability for fraud, gross negligence, willful misconduct, death or personal injury caused by negligence, or any liability that cannot be limited by law. Some jurisdictions don't allow certain exclusions or limitations, so some of the above may not apply to you.

14.4 Basis of the bargain. These limits reflect the allocation of risk between you and us, and our prices reflect them. They apply even if a limited remedy fails of its essential purpose.

15. Indemnity

You will defend and indemnify ARCH-CORE LAB and its officers, employees and agents against third-party claims, and related losses and reasonable legal fees, arising from Your Content, your use of the Service in breach of these Terms or the law, or your infringement of anyone's rights. We will tell you promptly about any such claim and let you control its defense, but you may not settle a claim in a way that admits fault by us or imposes obligations on us without our consent.

16. Changes to These Terms

We may update these Terms. For material changes, we will notify you by email and in the Service at least 30 days before they take effect, and we may ask you to accept the updated Terms when you next sign in. Changes apply only going forward; disputes about events before a change are governed by the Terms in effect at that time. If you don't agree to a change, you may cancel before it takes effect, and you keep access until the end of your current billing period. We may make non-material changes — such as clarifications or updated contact details — at any time by posting them. Previous versions are available on request.

17. Disputes

17.1 Talk to us first. Before filing any claim, you and we each agree to send the other a written notice describing the dispute and the relief sought — to us at legal@archcorelab.com, and to you at your account email. We will both try in good faith to resolve it for 45 days after the notice is received. Any deadline to file the claim is paused during those 45 days. Neither of us may file a lawsuit, other than in small-claims court or for emergency injunctive relief, until this period ends.

17.2 Where disputes are decided. Any dispute arising out of or relating to these Terms or the Service will be decided only in the state courts located in Cook County, Illinois, or the U.S. District Court for the Northern District of Illinois, and you and we consent to the personal jurisdiction of, and venue in, those courts. Either of us may instead bring an individual claim in a small-claims court that has jurisdiction.

17.3 Governing law. Illinois law governs these Terms, without regard to conflict-of-law rules. This does not take away any protection that the law of the place where you live gives you and that cannot be waived by contract.

17.4 Individual claims only. To the fullest extent permitted by law, you and we each agree to bring claims only in an individual capacity, and not as a plaintiff or class member in any class, collective, consolidated or representative proceeding. This Section does not waive any right to seek public injunctive relief, or any other right, that the law does not allow to be waived.

17.5 JURY WAIVER. TO THE FULLEST EXTENT PERMITTED BY LAW, YOU AND WE EACH WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY LAWSUIT ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE.

17.6 If part of this Section is unenforceable. If a court decides that Section 17.4 or 17.5 cannot be enforced for a particular claim or person, that subsection will not apply to that claim or person, but the rest of this Section 17, including Section 17.2, will still apply.

17.7 Time limit. Any claim must be filed within one year after it arises. This one-year limit does not apply to claims under the Illinois Consumer Fraud and Deceptive Business Practices Act, or under any other law that does not allow its filing deadline to be shortened by contract; those claims are subject to the deadline set by that law.

17.8 Costs. Each of us pays our own lawyers' fees and costs, unless a statute or the court awards them.

17.9 Business use. If you use the Service for a business, you confirm that you are acquiring it for business or professional purposes. This does not limit rights you have under law that cannot be waived.

18. U.S. Government Users

The Service and related software and documentation are "commercial products," "commercial services" and "commercial computer software" as defined in 48 C.F.R. §2.101, and are provided to U.S. Government users only with the rights granted to all other users under these Terms and the EULA, consistent with 48 C.F.R. §12.212 and §227.7202 (or any successor provisions).

19. General

Entire agreement. These Terms and the Privacy Policy (and, for the desktop application, the EULA) are the entire agreement between you and us about the Service.
Electronic notices. You agree that we may send notices and agreements to you electronically, including by email and in the Service.
Assignment. You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition or sale of assets.
Severability and waiver. If any part of these Terms is unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver.
Force majeure. Neither of us is liable for failures caused by events beyond our reasonable control, as described in Section 10.2.
Relationship. Nothing in these Terms creates a partnership, joint venture or agency relationship.
