Terms of Use — LionSync-ISO

Effective date:
November 8, 2026
Developer:
LionSync LLC

These Terms of Use ("Terms") are an agreement between you and LionSync LLC ("LionSync," "we," "us") covering your use of the LionSync-ISO application and any related updates (the "App"). By downloading, installing or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. Who may use the App

You must be at least 18 years old, or the age of majority where you live, to use the App. If you use the App on behalf of a company or other organization, you confirm that you are authorized to accept these Terms on its behalf, and "you" includes that organization.

2. License to use the App

We grant you a personal, limited, non-exclusive, non-transferable, revocable license to install and use the App on devices you own or control, for your own personal or business purposes, in accordance with these Terms and the usage rules of the app store you obtained it from.

You may not:

  • copy, modify, translate or create derivative works of the App;
  • reverse engineer, decompile or disassemble the App, except where the law expressly allows it;
  • rent, lease, sell, sublicense or redistribute the App or access to its paid features;
  • remove or alter any copyright, trademark or other notices in the App;
  • circumvent or tamper with the App's purchase verification or feature restrictions; or
  • use the App for any unlawful purpose.

3. Professional use and your responsibility

The App is a drawing and estimating aid for the construction trades. It is not engineering design software, and it does not replace the judgment of a qualified professional.

  • Specification defaults. Material grades, wall schedules, joint methods and similar selections the App suggests are general industry defaults. They are not calculations under any code or standard and may not suit your project. You are responsible for confirming every material, size, schedule, rating and method against the project specification, the engineer of record, the manufacturer's requirements and all codes and regulations that apply where the work is performed.
  • Takeoffs, cut lengths and estimates. Quantities, cut lengths and prices produced by the App depend on what you draw and the rates, prices and dimensions you enter. They may contain errors or omissions. Verify them before ordering material, cutting pipe, submitting a bid or relying on them in any other way.
  • Drawings. Drawings created in the App are not stamped, certified or approved documents and must not be represented as such.
  • Field conditions. You are responsible for site measurements, safety, permits, inspections and compliance with all laws and workplace safety requirements.

You use the App's output at your own risk. LionSync is not responsible for decisions you make, work you perform or costs you incur based on it.

4. LionSync-ISO Pro

The App is free to download and use. Certain features are available only with LionSync-ISO Pro, a one-time in-app purchase. Pro is not a subscription and does not renew.

  • Purchases are processed and billed by the app store you use (for example, Apple's App Store or Google Play) under that store's terms. We never receive your payment details.
  • Prices are shown in the App before you buy and may change for future purchases.
  • Refund requests are handled by the app store under its refund policy.
  • You can restore a purchase on another device signed in to the same store account using Restore Purchase.
  • Pro is licensed to you for use with the App; it has no cash value and cannot be transferred or resold.

5. Your drawings and data

You own the drawings, project files and other content you create in the App ("Your Content"). Your Content is stored on your device; we do not collect, receive or have access to it unless you choose to send it to us.

Because Your Content stays on your device, you are responsible for backing it up. Deleting the App, resetting or losing your device may permanently delete Your Content, and we cannot recover it.

If you export or share Your Content (for example, as a PDF), you are responsible for where you send it and for having the right to share any information it contains, such as client names or addresses.

Our collection and use of information is described in our Privacy Policy at https://lionsync.us/products/lionsync-iso/privacy, which forms part of these Terms.

6. Intellectual property

The App, including its software, design, symbols, artwork, names and logos, is owned by LionSync LLC or its licensors and is protected by intellectual property laws. "LionSync" and "LionSync-ISO" and the LionSync logo are our trademarks. These Terms do not give you any right to use them except to use the App as permitted here.

If you send us feedback or feature suggestions, including through app store reviews, you agree we may use them without restriction or obligation to you.

7. Disclaimer of warranties

TO THE FULLEST EXTENT PERMITTED BY LAW, THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE APP WILL BE ERROR-FREE OR UNINTERRUPTED, THAT ITS CALCULATIONS, QUANTITIES, MATERIAL SELECTIONS OR ESTIMATES WILL BE ACCURATE OR COMPLETE, OR THAT IT WILL MEET YOUR REQUIREMENTS OR ANY CODE OR STANDARD.

Some jurisdictions do not allow certain warranties to be excluded, so some of these exclusions may not apply to you.

8. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY LAW, LIONSYNC LLC AND ITS OWNERS, EMPLOYEES AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, BUSINESS, DATA OR CONTENT, OR FOR THE COST OF MATERIALS, LABOR, REWORK, DELAY OR PROPERTY DAMAGE, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE APP, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID FOR LIONSYNC-ISO PRO IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE, OR (B) US $50.

Some jurisdictions do not allow certain limitations of liability, so some of these limitations may not apply to you.

9. Indemnification

You agree to defend, indemnify and hold harmless LionSync LLC and its owners, employees and agents from any claims, damages, losses and expenses, including reasonable attorneys' fees, arising from your use of the App, Your Content, work you perform or bids you submit using the App's output, or your violation of these Terms or any law.

10. Apple App Store terms

If you downloaded the App from Apple's App Store, the following also applies:

  • These Terms are between you and LionSync LLC only, not Apple Inc. ("Apple"). LionSync, not Apple, is solely responsible for the App and its content.
  • Your license to use the App is limited to use on Apple-branded products you own or control, as permitted by the Usage Rules in Apple's Media Services Terms and Conditions.
  • LionSync, not Apple, is solely responsible for providing any maintenance and support for the App. Apple has no obligation to provide maintenance or support.
  • If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, of the App or in-app purchase. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App, and any other claims, losses or expenses due to a failure to conform to a warranty are LionSync's responsibility, subject to these Terms.
  • LionSync, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your use of it, including product liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
  • If a third party claims that the App or your use of it infringes their intellectual property rights, LionSync, not Apple, is solely responsible for investigating, defending, settling and discharging that claim.
  • You represent that you are not located in a country subject to a U.S. Government embargo or designated as a "terrorist supporting" country, and that you are not on any U.S. Government list of prohibited or restricted parties.
  • You must comply with any applicable third-party terms when using the App.
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, may enforce them against you.

11. Google Play

If you obtained the App from Google Play, your purchase is also subject to the Google Play Terms of Service, and Google is not responsible for the App or for support.

12. Changes to the App and these Terms

We may update, change or discontinue features of the App at any time. We may revise these Terms; the updated version will be posted at https://lionsync.us/products/lionsync-iso/terms with a new effective date. Continuing to use the App after a change means you accept the revised Terms.

13. Termination

These Terms apply until ended by you or us. You may end them at any time by deleting the App. Your license ends automatically if you breach these Terms. Sections 3 and 5 through 9 and 14 continue to apply after termination.

14. Governing law and general terms

These Terms are governed by the laws of the State of Nebraska, USA, without regard to its conflict-of-law rules, and any dispute will be brought in the state or federal courts located in Omaha, Nebraska, unless the law where you live requires otherwise.

If any part of these Terms is found unenforceable, the rest remains in effect. Our failure to enforce any part is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a sale or reorganization of our business. These Terms, together with the Privacy Policy, are the entire agreement between you and LionSync about the App.

The App is subject to U.S. export laws, and you agree to comply with them.
