NESTFLOW · Terms of Use and License Agreement

Last updated: September 30, 2026

These Terms govern the use of NESTFLOW (the "Software"), a production engine for Adobe Illustrator published by Cero Stress ("we", "us"). By installing or using the Software you agree to these Terms. You must be 18 years of age or older to accept them.

1. License and subscription

We grant you a non-exclusive, non-transferable license to install and use the Software on up to two computers at a time that you own or control, for your own business or personal use.

NESTFLOW is an automatically renewing subscription, monthly or yearly. By subscribing you authorize our merchant of record (currently Lemon Squeezy) to charge the price shown at checkout (currently US$9.99 per month or US$99 per year, plus applicable taxes) every period until you cancel. Cancel anytime from the panel (License → Cancel subscription), which takes effect immediately, or in the Lemon Squeezy customer portal; if you ask us by email, do so at least 48 hours before your billing date. Once you cancel, you are not charged again and you keep access until the end of the period you paid for (the month or the year). If we change the price, we email you between 7 and 30 days before your next renewal, with the link to cancel.

The subscription includes every update released while it is active. When it ends, the Software stops nesting, applying and exporting in the document until a license is active again.

You may release a computer from the panel (License → Release this machine) to activate on another.

2. Trial

The Software may be evaluated for 7 days per computer with a free evaluation key. The key is requested with an email address on our website and delivered by email; entering it unlocks the full panel. The evaluation does not ask for a card and does not turn into a subscription on its own. After 7 days the Software locks until a license is activated. The Software keeps a local record of the evaluation that survives uninstalling, and circumventing it is a breach of these terms.

3. Restrictions

You may not: sell, rent, sublicense or share your license key; reverse engineer or circumvent the license system; remove notices; or use the Software to provide it as a service to third parties. One license key belongs to one person or business.

4. Activation and connectivity

Activation checks the key against our license server. Offline activation is available through a file exchanged by email with license@cero-stress.com. A license keeps working for up to seven days offline. Each time the panel opens with internet, it confirms the license is still active and counts another seven days; after seven days without a connection, a connection (or a new file by email) is needed to continue. This check is not a charge: the subscription is billed monthly, as section 1 says.

5. Ownership

The Software is licensed, not sold. We keep all rights, title and interest in it. Your files and designs are yours; we never receive them.

6. Data

The Software runs locally. The Privacy Policy explains what data it sends for the license and what it never sends (your documents). We do not use your data to train artificial intelligence models.

7. Updates

We may release updates that fix bugs or add features. Updates may change or remove features. If an update removes an essential feature of the Software (for example, nesting, applying or exporting the cut file), we email you and you may cancel with a refund of the unused part of the month. We are not obliged to support versions older than the current one.

8. Warranty

The Software is provided "as is". We do not warrant that it is error-free or fits every workflow. You are responsible for checking every layout and cut file before cutting material: the Software estimates time and material and computes cut paths, and a mistake in setup or in the machine can waste material or damage tools. Check the preview, the numbers and the DXF before you cut. Nothing in this section limits liability that the law does not allow to be limited (willful misconduct, gross negligence) or the non-waivable rights your country's consumer law gives you.

9. Limitation of liability

To the extent permitted by law, our total liability for any claim related to the Software is limited to the amount you paid for it in the twelve months before the claim. We are not liable for lost profits, wasted material, machine damage or indirect damages. Nothing in this section limits liability that the law does not allow to be limited (willful misconduct, gross negligence) or the non-waivable rights your country's consumer law gives you.

10. Refunds

See the Refund Policy.

11. Termination

We may terminate your license if you breach these Terms. On termination you must stop using the Software. Sections 3, 5, 8, 9 and 12 survive.

If we stop selling NESTFLOW, we email you at least 30 days in advance and you are not charged again.

12. Governing law

These Terms are governed by the laws of the Republic of Panama. Disputes are resolved in the courts of Panama City, unless the law where you live gives you other rights.

13. Changes

We may update these Terms. The date at the top shows the current version. If a change is material, we email you at least 30 days before it takes effect. If you do not agree, you may cancel before that date and we refund the unused part of the month. Price changes follow section 1.

14. Trademarks

Adobe and Illustrator are either registered trademarks or trademarks of Adobe in the United States and/or other countries. NESTFLOW is an independent product: it is not affiliated with, sponsored or endorsed by Adobe.

15. Language

These Terms are published in Spanish and English. If the two versions differ, the Spanish version prevails.

16. Severability

If a court finds any part of these Terms void or unenforceable, that part applies to the extent the law allows and the rest remains in effect.
