Terms of Use

Last updated: 2026-04-27

These Terms of Use (the "Terms") govern your access to and use of the Light Tracer website, applications, rendering tools, account features, content hosting features, and related services (collectively, the "Service"). The Service is operated by Light Engine LLC, a limited liability company incorporated under the laws of the Republic of Armenia ("Light Engine", "we", "us", or "our").

By accessing or using the Service, you agree to these Terms. If you use the Service for a company or other organization, you represent that you have authority to bind that organization, and "you" includes that organization. If you do not agree to these Terms, do not use the Service.

Our collection and use of personal information is described in our Privacy Policy. If this link is unavailable in your version of the site, contact us at info@lighttracer.org for a copy.

Changes to these Terms

We may update these Terms from time to time. The "Last updated" date above shows when these Terms were last revised. Changes become effective when posted unless we state otherwise. Your continued use of the Service after changes are posted means that you accept the updated Terms. If a change is material and we have your email address, we may also notify you by email or through the Service.

The Service

Light Engine provides tools for uploading, storing, viewing, rendering, and sharing 3D models and related files, including services based on the Light Tracer Render engine. We may add, change, suspend, limit, or discontinue any part of the Service at any time, including free, beta, trial, or experimental features.

You are responsible for obtaining and maintaining the hardware, software, internet connection, browser, and other equipment needed to use the Service. Rendering, visualization, and file-processing results may vary based on model data, browser support, device capabilities, network conditions, and service availability.

Eligibility

You must be at least 13 years old to use the Service. If you are under the age of majority where you live, you may use the Service only with the consent and supervision of a parent or legal guardian. The Service is not directed to children under 13, and you may not use the Service if you are barred from doing so under applicable law.

Accounts

Some parts of the Service require an account. You agree to provide accurate, current, and complete account information and to keep it updated. You are responsible for safeguarding your login credentials and for all activity under your account. Notify us promptly at info@lighttracer.org if you believe your account has been compromised.

We may suspend, restrict, or terminate your account or access to the Service if we reasonably believe that you violated these Terms, created risk or possible legal exposure for Light Engine or others, used the Service unlawfully, or caused harm to the Service, other users, or third parties.

User Content

"User Content" means 3D models, files, materials, textures, images, descriptions, comments, and other content that you upload, submit, publish, display, or otherwise make available through the Service.

You retain ownership of your User Content. You are solely responsible for your User Content and for ensuring that you have all rights, licenses, permissions, and consents needed to upload it and to grant the licenses described in these Terms. You represent and warrant that your User Content and our use of it as permitted by these Terms will not violate any law, infringe or misappropriate any third-party right, or breach any agreement that applies to you.

By submitting User Content, you grant Light Engine a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, render, convert, modify for technical formatting, transmit, display, and otherwise use your User Content as necessary to operate, provide, secure, improve, and support the Service. If you make User Content public or share it through public features, you also grant Light Engine the right to display, distribute, promote, and make that User Content available to other users and site visitors through the Service.

Unless you separately agree otherwise, Light Engine will not sell your private User Content as standalone content. We may retain backup copies, logs, cached files, thumbnails, renders, and records where reasonably necessary for security, legal compliance, dispute resolution, fraud prevention, or ordinary backup and archival purposes.

When you make User Content public, you allow other users and visitors to access, view, and use that User Content through the normal functionality of the Service. You understand that public User Content may be copied or used by others outside our control.

We may review, moderate, remove, disable access to, or refuse to host User Content at any time if we reasonably believe it violates these Terms, infringes third-party rights, creates security or operational risk, or may expose Light Engine or others to liability. We are not obligated to monitor User Content and are not responsible for User Content posted by users.

Light Engine Content and Intellectual Property

The Service, Light Tracer Render, Light Engine software, rendering technology, designs, interfaces, logos, trademarks, text, graphics, databases, code, and other materials provided by Light Engine are owned by Light Engine or its licensors and are protected by intellectual property and other laws. Except for the limited right to use the Service in accordance with these Terms, no rights are transferred to you.

You may not copy, modify, distribute, sell, lease, sublicense, reverse engineer, decompile, or attempt to extract source code from the Service or Light Engine software, except to the extent that applicable law expressly permits such activity despite this restriction.

Acceptable Use

You agree not to use the Service to:

• violate any applicable law, regulation, court order, or third-party right;
• upload or share content that infringes copyright, trademark, trade secret, privacy, publicity, contractual, or other rights;
• upload malware, malicious code, corrupted files, or content designed to disrupt, damage, or gain unauthorized access to any system or data;
• harass, threaten, defraud, impersonate, or mislead any person or entity;
• interfere with, overload, scan, probe, bypass, or compromise the security, integrity, or availability of the Service;
• use bots, scrapers, crawlers, automated tools, or bulk extraction methods except as expressly permitted by Light Engine in writing or by publicly documented interfaces;
• circumvent access controls, usage limits, payment obligations, metering, rendering limits, or technical restrictions;
• use the Service to develop or improve a competing service by unauthorized copying, benchmarking, scraping, or reverse engineering;
• remove, obscure, or alter proprietary notices displayed through the Service; or
• upload content or use the Service in a way that subjects Light Engine to export-control, sanctions, or trade-compliance violations.

Nothing in these Terms restricts your right to make truthful statements, reviews, or comments about Light Engine or the Service, provided that your statements comply with applicable law.

Payments, Subscriptions, and Taxes

Paid features, subscriptions, credits, or licenses may be offered directly by Light Engine or through third-party payment providers. Prices, billing periods, renewal terms, cancellation options, refund rules, and taxes will be disclosed at checkout or in the applicable order, invoice, or subscription flow. You authorize the applicable payment provider to charge the payment method you provide for amounts due.

Except where required by law or expressly stated at checkout, fees are non-refundable. You are responsible for all taxes, duties, and governmental charges associated with your purchase, excluding taxes based on Light Engine's net income.

Third-Party Services

The Service may link to, integrate with, or rely on third-party websites, software, payment processors, analytics providers, hosting providers, libraries, or other services. We do not control third-party services and are not responsible for their content, policies, availability, security, or practices. Your use of third-party services may be governed by separate terms and privacy policies.

Copyright and Intellectual Property Complaints

If you believe that content available through the Service infringes your copyright or other intellectual property rights, contact us at info@lighttracer.org and include enough information for us to identify the content and evaluate the complaint, including your contact information, a description of the protected work, the URL or location of the allegedly infringing material, a statement that you have a good-faith belief that the use is unauthorized, and a statement that the information in your notice is accurate.

For copyright complaints under the United States Digital Millennium Copyright Act, notices and counter-notices should include the information required by 17 U.S.C. Section 512. We may remove or disable access to allegedly infringing content and may terminate accounts of repeat infringers in appropriate circumstances. Submitting false or misleading notices may create legal liability.

Feedback

If you provide ideas, suggestions, bug reports, feature requests, or other feedback, you grant Light Engine a perpetual, worldwide, irrevocable, transferable, sublicensable, royalty-free license to use that feedback for any purpose without restriction or compensation to you. This does not transfer ownership of your User Content.

Availability and Beta Features

We work to keep the Service available, but we do not guarantee uninterrupted, error-free, secure, or loss-free operation. The Service may be unavailable due to maintenance, updates, network issues, third-party failures, power failures, security incidents, force majeure events, or other causes. Beta, trial, preview, or experimental features may be changed or discontinued at any time and may be less reliable than generally available features.

Disclaimers

To the fullest extent permitted by applicable law, the Service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, quiet enjoyment, and uninterrupted operation.

Light Engine does not warrant that the Service will meet your requirements, that rendered results will be accurate or suitable for a particular use, that User Content will be preserved without loss, or that the Service will be free from vulnerabilities, viruses, errors, or harmful components.

Limitation of Liability

To the fullest extent permitted by applicable law, Light Engine and its owners, directors, officers, employees, contractors, licensors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, loss of goodwill, business interruption, or substitute services, arising out of or related to the Service or these Terms, even if advised of the possibility of such damages.

To the fullest extent permitted by applicable law, Light Engine's total liability for all claims arising out of or related to the Service or these Terms will not exceed the greater of (a) the amount you paid to Light Engine for the Service giving rise to the claim during the 12 months before the event giving rise to liability, or (b) USD 100.

Some jurisdictions do not allow certain disclaimers or limitations of liability. In those jurisdictions, the disclaimers and limitations above apply only to the maximum extent permitted by law. Nothing in these Terms limits liability that cannot legally be limited, including liability for intentional misconduct where such limitation is prohibited by law.

Indemnification

To the fullest extent permitted by applicable law, you agree to defend, indemnify, and hold harmless Light Engine and its owners, directors, officers, employees, contractors, licensors, and service providers from and against claims, liabilities, damages, losses, and expenses, including reasonable attorneys' fees, arising out of or related to your User Content, your use of the Service, your violation of these Terms, your violation of law, or your infringement or misappropriation of any third-party right.

If you are a consumer, this indemnity applies only to the extent permitted by applicable law. We reserve the right to control the defense of any matter subject to indemnification, and you agree to cooperate with our defense of those claims.

Termination

You may stop using the Service at any time. We may suspend or terminate your access to the Service at any time if we reasonably believe that you violated these Terms, your use creates risk for Light Engine or others, or continued access is no longer commercially or technically feasible.

After termination, provisions that by their nature should survive will survive, including provisions about ownership, User Content licenses already granted for public content or required for legal and operational purposes, disclaimers, limitations of liability, indemnification, governing law, and dispute resolution.

Governing Law and Disputes

These Terms are governed by the laws of the Republic of Armenia, without regard to conflict-of-law rules, except where applicable consumer protection, data protection, intellectual property, or other mandatory laws provide otherwise.

If you are a consumer located in the United States or another jurisdiction that provides mandatory consumer rights, nothing in these Terms is intended to waive rights that cannot be waived by contract. Before filing a formal claim, you agree to contact us at info@lighttracer.org so we can try to resolve the dispute informally.

General Terms

You may not assign or transfer these Terms or your account without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, sale of assets, or by operation of law. If any provision of these Terms is found invalid or unenforceable, the remaining provisions will remain in effect, and the invalid or unenforceable provision will be enforced to the maximum extent permitted by law.

Our failure to enforce a provision is not a waiver of our right to do so later. These Terms, together with any additional terms presented for specific features or purchases, are the entire agreement between you and Light Engine regarding the Service.
