Terms of Service
Last updated: March 2026
These Terms of Service (“Terms”) govern your use of the website opulion.dev and any consulting services provided by Opulion Systems LLC (“we,” “us,” or “our”). By accessing the site or engaging our services, you agree to these Terms. If you do not agree, please do not use our site or services.
01
About Opulion Systems LLC
Opulion Systems LLC is a production machine-learning consulting firm founded by mostafa Elhadary and based in Wyoming, USA. We serve clients globally, providing ML diagnostics, advisory retainers, and production engineering services.
02
Services
We offer consulting engagements that typically include production ML diagnostics, root-cause analysis, architecture review, and implementation guidance. The specific scope, deliverables, and timeline for each engagement are defined in the corresponding proposal or statement of work shared with you before work begins.
We reserve the right to decline any engagement at our discretion. All delivery timelines are estimates and may shift based on the complexity uncovered during the engagement.
03
Payments & Billing
All payments are processed through PayPal. When you purchase a service, your payment method is charged immediately at the time of checkout. Prices are listed in USD unless otherwise stated.
Refund policy: If you are not satisfied with the deliverable from a diagnostic engagement, we offer a full refund provided you request it within 7 days of delivery. Retainer fees are non-refundable for the current billing period but you may cancel future renewals at any time. Custom engagements follow the refund terms specified in their individual proposals.
We may update pricing at any time. Price changes do not affect engagements that have already been paid for.
04
Accounts & Access
Certain areas of the site (such as client dashboards or proposal pages) may require authentication. You are responsible for maintaining the confidentiality of your account credentials and for all activity under your account.
05
Intellectual Property
All content on opulion.dev — including text, graphics, logos, blog articles, case studies, and code samples — is owned by Opulion Systems LLC or its licensors and is protected by applicable intellectual property laws.
Client deliverables: Upon full payment, you receive a non-exclusive, perpetual license to use the deliverables produced for your engagement. We retain the right to reference the general nature of the work (without disclosing confidential details) in marketing materials and case studies, unless you request otherwise in writing.
Pre-existing IP: Any frameworks, tools, or methodologies we developed before or independently of your engagement remain our property. You receive a license to use them within the scope of your project.
06
Acceptable Use
You agree not to:
- Use the site or our services for any unlawful purpose
- Attempt to gain unauthorized access to any part of the site
- Scrape, crawl, or harvest content from the site without permission
- Misrepresent your identity or affiliation when engaging with us
- Redistribute deliverables to third parties without written consent
07
Confidentiality
Both parties agree to keep confidential any proprietary information shared during an engagement. This includes (but is not limited to) technical architecture details, business data, model performance metrics, and any deliverables marked as confidential.
If a separate NDA or confidentiality agreement is signed, its terms take precedence over this section.
08
Limitation of Liability
To the maximum extent permitted by law, Opulion Systems LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from or related to your use of our site or services — including lost profits, data loss, or business interruption.
Our total liability for any claim related to an engagement shall not exceed the amount you paid for that specific engagement. This limitation applies regardless of the theory of liability (contract, tort, strict liability, or otherwise).
We provide our services and deliverables on an “as-is” basis. While we strive for accuracy and quality, we do not warrant that our recommendations will produce any specific business outcome.
09
Termination
Either party may terminate an engagement by providing written notice. If you terminate mid-engagement, fees for work already completed are non-refundable. We reserve the right to suspend or terminate access to the site for any user who violates these Terms.
10
Governing Law & Disputes
These Terms are governed by the laws of the State of Wyoming, USA. Any disputes arising from these Terms or our services shall first be addressed through good-faith negotiation. If negotiation fails, the dispute shall be submitted to the competent courts of Wyoming, USA.
For clients in the European Union, nothing in these Terms affects your statutory consumer rights under EU law.
11
Changes to These Terms
We may update these Terms from time to time. Material changes will be posted on this page with an updated revision date. Continued use of the site or services after changes constitutes acceptance of the revised Terms.
