Terms of Service

Welcome, and thank you for your interest in Reflux ("Reflux," "we," "our," or "us"). These Terms of Service ("Terms") govern your access to and use of Reflux's software, websites, applications, command-line tools, APIs, model-assisted planning systems, simulator adapters, documentation, and related services (collectively, the "Service"). By accessing or using the Service, you agree to these Terms.

If you use the Service on behalf of a company, university, laboratory, government agency, or other organization, you represent that you have authority to bind that organization to these Terms. If your organization has a separate master services agreement, order form, data processing addendum, or similar written agreement with Reflux, that agreement controls where it conflicts with these Terms.

1. Access and Use

1.1. Provision of access. Reflux provides AI-assisted tools for technical simulation workflows. The Service can help process engineers and other technical users inspect simulator files, draft reviewed plans, interact with desktop simulation software, execute supported workflow steps, and summarize results. Subject to your compliance with these Terms, Reflux grants you a limited, non-exclusive, non-transferable, revocable right to access and use the Service for your internal business or evaluation purposes.

1.2. Content. You may provide prompts, messages, simulator files, flowsheets, model inputs, chemistry data, process data, operating targets, results, feedback, and other materials to the Service ("Inputs"). The Service may return plans, suggested edits, scripts, reports, simulator commands, generated files, summaries, and other outputs ("Outputs"). Inputs and Outputs are collectively "Content." You are responsible for ensuring that you have all rights, licenses, consents, and permissions needed for Reflux to process your Inputs and provide the Service.

1.3. Engineering review. Outputs are generated by software and AI systems and may be incomplete, incorrect, unsafe, infeasible, or unsuitable for your use case. Reflux is designed around reviewable plans and visible simulator actions, but it is not a substitute for professional engineering judgment, process safety review, operating procedures, management of change, hazard analysis, regulatory review, or qualified sign-off. You are solely responsible for verifying any Output before relying on it.

1.4. Model training. Reflux will not use your private simulator files, prompts, or workflow Content to train general-purpose AI models unless you expressly agree or submit Content to a feature that clearly states it is intended for that purpose. We may process Content to provide, secure, debug, support, and improve the Service, and we may use aggregated or de-identified usage data that does not identify you or your organization.

1.5. Auto-execution and simulator control. The Service may include features that execute commands, modify simulator cases, generate files, run calculations, or interact with installed desktop software. You are responsible for reviewing the planned action, using appropriate test environments and backups, and confirming that the resulting files, calculations, and recommendations are safe and suitable for your intended purpose.

1.6. Beta services. Some features may be labeled alpha, beta, preview, experimental, research, early access, or evaluation. Beta services are provided for testing and feedback, may be changed or discontinued at any time, and may be less reliable than generally available features.

2. Eligibility

You must be at least 18 years old, or the age of majority in your jurisdiction, whichever is higher, to use the Service. You may not use the Service if you are barred from doing so under applicable law or if your account has been suspended or terminated for a violation of these Terms.

3. Accounts and Security

You may need an account to access some parts of the Service. You agree to provide accurate, complete, and current account information and to keep your credentials secure. You are responsible for activity under your account. Notify Reflux promptly if you believe your account, tokens, simulator connection, or credentials have been compromised.

4. Payment Terms

Certain features may require fees, subscriptions, usage-based charges, or a paid order form. Fees are due as described at the time of purchase or in the applicable order form. Unless otherwise stated in writing or required by law, fees are non-refundable. You are responsible for taxes associated with your use of the Service, other than taxes based on Reflux's net income.

5. Ownership and Licenses

5.1. Service. Reflux and its licensors own all rights, title, and interest in and to the Service, including software, interfaces, models, workflows, documentation, designs, and related intellectual property. No rights are granted except as expressly stated in these Terms.

5.2. Your Content. As between you and Reflux, you retain your rights in your Inputs. Subject to these Terms and any third-party rights, Reflux assigns to you its rights, if any, in Outputs generated for you. You grant Reflux the rights needed to host, process, transmit, reproduce, display, and create derivative works from Content solely as necessary to provide, secure, support, and improve the Service.

5.3. Feedback. If you provide feedback, ideas, or suggestions, you grant Reflux a perpetual, irrevocable, worldwide, royalty-free license to use that feedback without restriction or compensation.

6. Third-Party Software and Services

The Service may interoperate with third-party simulators, desktop applications, cloud services, model providers, package managers, operating systems, and file formats. Reflux is not responsible for third-party products and does not grant you any license to them. You are responsible for obtaining and complying with any required third-party licenses, credentials, vendor terms, and safety requirements.

7. Use Restrictions

You may not misuse the Service, interfere with its operation, bypass access controls, reverse engineer non-public parts of the Service, probe or attack the Service, use the Service to violate law or third-party rights, submit malicious code, use Outputs to build a directly competing model or service through model extraction, or remove proprietary notices. You may not use the Service for decisions or operations where failure could cause death, personal injury, environmental harm, property damage, or regulatory noncompliance unless you apply appropriate independent review, safeguards, testing, and professional oversight.

8. Confidentiality

If Reflux and you exchange non-public information that a reasonable person would understand to be confidential, the receiving party will use it only to perform under these Terms and will protect it using reasonable care. Confidentiality obligations do not apply to information that is public through no fault of the receiving party, already known without restriction, independently developed, or lawfully received from another source.

9. Privacy

Reflux's privacy practices are described in our Privacy Policy. If you use the Service as part of an organization, your organization's administrator may be able to access, manage, export, or delete Content associated with your workspace according to the settings and agreements that apply to that workspace.

10. Changes to the Service or Terms

We may modify the Service or these Terms from time to time. If we make material changes to these Terms, we will provide notice by updating the date on this page or by other reasonable means. Your continued use of the Service after changes take effect means you accept the updated Terms.

11. Termination

You may stop using the Service at any time. We may suspend or terminate your access if you violate these Terms, create risk for the Service or other users, fail to pay fees, or if we discontinue the Service. Upon termination, your right to use the Service ends. Sections that by their nature should survive termination will survive, including ownership, confidentiality, payment obligations, disclaimers, limitations of liability, indemnity, dispute resolution, and miscellaneous terms.

12. Copyright Complaints

If you believe material available through the Service infringes your copyright, please contact Reflux with enough information for us to identify the material and evaluate the claim. We may remove or disable access to material that we believe may infringe third-party rights and may terminate accounts of repeat infringers where appropriate.

13. Disclaimer of Warranties

THE SERVICE AND OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, REFLUX DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, QUIET ENJOYMENT, NON-INFRINGEMENT, ACCURACY, RELIABILITY, AVAILABILITY, AND SAFETY. REFLUX DOES NOT WARRANT THAT THE SERVICE OR OUTPUTS WILL BE ERROR-FREE, SECURE, UNINTERRUPTED, COMPLETE, OR SUITABLE FOR ANY ENGINEERING, OPERATIONAL, REGULATORY, OR COMMERCIAL PURPOSE.

14. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, REFLUX AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOSS OF DATA, BUSINESS INTERRUPTION, SIMULATOR FILE CORRUPTION, PRODUCTION LOSSES, OR GOODWILL DAMAGES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TO THE FULLEST EXTENT PERMITTED BY LAW, REFLUX'S AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF THE AMOUNT YOU PAID TO REFLUX FOR THE SERVICE IN THE SIX MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR $100.

15. Indemnity

To the fullest extent permitted by law, you will defend, indemnify, and hold harmless Reflux from claims, damages, liabilities, losses, and expenses, including reasonable attorneys' fees, arising from your Content, your use or misuse of the Service, your violation of these Terms, your violation of law or third-party rights, or engineering, operational, or business decisions you make based on Outputs.

16. Dispute Resolution

Before filing a claim, you and Reflux agree to try to resolve disputes informally by contacting the other party and describing the dispute in reasonable detail. These Terms are governed by the laws of the State of Delaware, excluding its conflict of laws rules, unless another governing law is required by an agreement between you and Reflux or by applicable law.

17. Export and Trade Controls

You must comply with applicable export control, sanctions, and trade laws. You may not use the Service in, for the benefit of, or in connection with embargoed jurisdictions, prohibited parties, or restricted end uses in violation of applicable law.

18. Miscellaneous

These Terms, together with any written agreement that expressly supplements them, constitute the entire agreement between you and Reflux regarding the Service. You may not assign these Terms 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 is unenforceable, the remaining provisions will remain in effect. Failure to enforce a provision is not a waiver.
