Terms of Use

Last updated October 24, 2026

These Terms of Use (“Terms”) are an agreement between you and Zukisan Labs, LLC (“Zukisan Labs,” “we,” or “us”) covering your use of the Nestmark app and website (together, “Nestmark”). By using Nestmark, you agree to these Terms. If you don’t agree, please don’t use Nestmark.

1. What Nestmark is

Nestmark is a planning tool. It estimates how pieces can be laid out on sheets, rolls, and linear stock, how much material a project may need, and what that material may cost. It doesn’t cut anything, inspect your material, or know about your tools, your shop, or your experience.

2. Check before you cut

Everything Nestmark produces, including layouts, cut lists, measurements, material quantities, waste figures, cost estimates, PDFs, and calculator results, is an estimate based on the information you enter. Results can be wrong because of incorrect or incomplete input, differences between nominal and actual material sizes, blade kerf or machine variation, material defects, rounding when measurements are displayed, or errors in the app.

You are responsible for:

• measuring your material and checking every dimension before you cut;
• deciding whether a layout suits your project, material, and tools;
• buying the right amount of material; and
• working safely, including following your tool manufacturers’ instructions and using appropriate safety equipment.

Zukisan Labs is not responsible for wasted or damaged material, miscut pieces, extra purchases, project delays, cost differences, or any injury or property damage that results from cutting, handling material, or relying on anything Nestmark produces.

3. Your account

Some features require an account. Please give accurate information, keep your login secure, and tell us if you think someone has accessed your account without permission. You’re responsible for activity on your account. You can delete it at any time from Settings in the app.

4. Purchases

Nestmark is free to use for planning. Nestmark Pro is a one-time in-app purchase that adds features such as the Library, cost estimates, and synced job history. Purchases are processed by Apple under Apple’s terms, and refunds are handled by Apple. We may add, change, or remove features over time.

5. Your content

You own the materials, cut lists, and jobs you create. You give us permission to store, sync, and display that content only as needed to run Nestmark for you. Our Privacy Policy explains how we handle information.

6. Acceptable use

Please don’t misuse Nestmark. For example, don’t:

• copy, modify, or reverse engineer the app, except where the law allows it;
• interfere with, overload, or try to break our services or the services we rely on;
• access other people’s accounts or data; or
• use Nestmark for anything unlawful.

7. Our app and your license

Nestmark, including its software, design, and branding, belongs to Zukisan Labs and is protected by intellectual property laws. We give you a personal, non-exclusive, non-transferable, revocable license to use the app on Apple devices you own or control, under these Terms and Apple’s Licensed Application End User License Agreement. If the two conflict about the license itself, Apple’s agreement controls.

8. Third-party services

Nestmark relies on services from Apple, Google Firebase, RevenueCat, and PostHog. Their own terms and privacy policies apply to their services.

9. Disclaimer of warranties

Nestmark is provided “as is” and “as available.” To the fullest extent allowed by law, Zukisan Labs disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not promise that Nestmark will be error-free or uninterrupted, or that its results will be accurate or suitable for your project.

10. Limitation of liability

To the fullest extent allowed by law, Zukisan Labs and its owners, employees, and contractors will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost or damaged materials, lost profits, or lost data, arising from or related to your use of Nestmark, even if we were told such damages were possible. Our total liability for any claim related to Nestmark is limited to the greater of the amount you paid for Nestmark in the 12 months before the claim or US $50.

Some places don’t allow these limits, so some of them may not apply to you.

11. Indemnity

If your misuse of Nestmark or your breach of these Terms leads to a claim against Zukisan Labs, you agree to cover our reasonable losses and costs from that claim, to the extent the law allows.

12. Ending your use

You can stop using Nestmark and delete your account at any time. We may suspend or end your access if you break these Terms or if we stop offering Nestmark. Sections 2 and 9 through 13 continue to apply after your use ends.

13. Governing law

These Terms are governed by the laws of the State of Oregon, USA, without regard to its conflict of law rules. Any dispute will be resolved in the state or federal courts located in Multnomah County, Oregon, and you and we agree to those courts’ jurisdiction. If you live somewhere that gives consumers the right to bring claims in their local courts, this section doesn’t take that right away.

14. Changes to these Terms

We may update these Terms from time to time. When we do, we’ll change the date at the top, and for significant changes we’ll let you know in the app or on this page. If you keep using Nestmark after an update, you accept the updated Terms.

15. If you got Nestmark from the App Store

• These Terms are between you and Zukisan Labs, not Apple. Apple isn’t responsible for Nestmark or its content.
• Apple has no obligation to provide maintenance or support for Nestmark.
• If Nestmark fails to meet an applicable warranty, you can notify Apple, and Apple may refund the purchase price. To the extent the law allows, Apple has no other warranty obligation for Nestmark.
• Apple isn’t responsible for addressing claims about Nestmark, including product liability claims, claims that it fails to meet a legal or regulatory requirement, consumer protection claims, or claims that it infringes someone’s intellectual property. Those are ours to handle, subject to these Terms.
• You confirm that you’re not located in a country subject to a U.S. government embargo and that you’re not on a U.S. government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
