This Agreement governs installation and use of the Eureka3X software, including the Free 3x version, the 3x Basic version, and the 3x Pro subscription version ('Software'). By installing, accessing, or using the Software, you agree to be bound by this Agreement. If you do not agree, do not install or use the Software.

Roboris S.r.l. grants you a personal, non-exclusive, non-transferable license to install and use the Software on devices under your control, provided it is actively used by only one authorized user at a time. Access to 3x Pro and 3x Basic features, including updates, portal downloads, and Machine Configurations, is provided only during an active subscription term. The Free 3x version remains available subject to feature limitations defined by Roboris. You may evaluate the 3x Pro version by activating a 30-day trial, which requires no credit card upfront. At the conclusion of the trial period, continued use of Pro features requires an active subscription.

The Software, including Free 3x, 3x Basic, 3x Pro, and all related Machine Configurations, may not be sold, sublicensed, leased, redistributed, bundled with paid services, or otherwise commercially transferred without prior written authorization from Roboris S.r.l. Authorized resellers and partners operating under written agreement with Roboris are exempt. Machine Configurations contain proprietary kinematic representations and technical modeling and are considered confidential technical material and trade secrets of Roboris. Machine Configurations may not be copied, shared, transferred, sold, distributed, published, or otherwise provided outside the licensed organization without prior written authorization from Roboris S.r.l.

1. Online Purchases via Paddle: If you purchased your subscription online through Paddle, all payments are processed by Paddle.com Market Limited, acting as the Merchant of Record, and your purchase is subject to Paddle's Buyer Terms (https://www.paddle.com/legal/buyer-terms). Because the Software is digital content provided immediately upon purchase, all sales are final and non-refundable, except where statutory withdrawal rights apply under applicable law (such as the EU/UK 14-day withdrawal right, provided it has not been waived by accessing the content) or as expressly permitted at Paddle's sole discretion.

2. Purchases via Custom Quote or Reseller: If you purchased your subscription directly from Roboris S.r.l. via a custom quote (e.g., paid via Stripe) or through an authorized distributor/reseller, the transaction is governed by the specific terms provided on your quote, invoice, or reseller agreement. Generally, for business-to-business (B2B) transactions and custom orders, all sales are final and non-refundable unless explicitly stated otherwise in your specific agreement.

Cancellations: Subscriptions may be cancelled at any time to prevent future renewals, but cancellation does not provide a pro-rated refund for the current billing period unless required by applicable law.

You agree to comply with all applicable export control laws and sanctions regulations of the European Union, Italy, the United States, and other relevant jurisdictions. The Software may not be used in connection with nuclear, missile, chemical, biological weapons development, or by sanctioned entities.

Machine Configurations are generic templates and not certified machine parameters. Customers are responsible for validating machine limits, axis behavior, tooling, fixtures, offsets, and safe operation prior to production use.

You may not analyze, derive, extract, reconstruct, or otherwise attempt to determine the structure, motion logic, axis relationships, kinematic transformations, or internal modeling methods of any Machine Configuration supplied with the Software. Machine Configurations may not be used to develop competing simulation models, digital twins, post-processors, machine definitions, or to reproduce, emulate, or derive machine definitions for competing commercial software products without written authorization from Roboris.

The Software may include mechanisms to verify license compliance and improve functionality. Use of the Software is subject to the Roboris Privacy Policy available at https://www.eureka3x.com/privacy.

You may not reverse engineer, decompile, modify, bypass licensing controls, create derivative works, or use the Software in violation of applicable laws. Unauthorized redistribution or sharing of Machine Configurations constitutes a material breach of this Agreement.

The Software, Machine Configurations, documentation, and related materials remain the exclusive property of Roboris S.r.l. This Agreement grants a license, not ownership rights.

Any feedback, suggestions, or improvement ideas provided may be used by Roboris without restriction or compensation.

The Software is provided 'AS IS' without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or accuracy of simulation results.

To the maximum extent permitted by law, Roboris shall not be liable for machine damage, tooling damage, lost production, indirect damages, consequential damages, or business interruption. Total liability is limited to fees paid for 3x Pro during the previous 12 months. No liability applies to Free 3x users except where required by law.

You agree to indemnify and hold harmless Roboris from claims arising from misuse of the Software, violation of export laws, unauthorized redistribution, or breach of this Agreement.

Roboris may terminate this Agreement for breach, non-payment, export violations, or unauthorized distribution. Upon termination, access to 3x Pro ends immediately.

Support services may be provided under separate agreements or subscription plans and are not guaranteed for Free 3x users.

Roboris may update this Agreement from time to time. Continued use of the Software after updates constitutes acceptance of revised terms.

This Agreement is governed by the laws of Italy. Business users agree to the exclusive jurisdiction of the Court of Pisa, Italy. Consumers resident in the EU, United States, or other jurisdictions with mandatory consumer forum rights may bring claims in their local courts where applicable law allows.

This Agreement constitutes the complete agreement governing use of Eureka3X and supersedes prior agreements relating to the Software.
