Terms of Service
Last updated: March 24, 2026
These Terms of Service ("Terms") govern your access to and use of the products and services provided by Cor Stellaris LLC ("we," "our," or "us"), including but not limited to OptiCoat Designer, ABO Prep, and any other products offered through the Cor Stellaris platform. By using our services, you agree to these Terms.
1. Accounts
You must create an account to use certain features of our products. You are responsible for maintaining the security of your account credentials and for all activities that occur under your account.
2. Subscriptions & Billing
Some of our products offer paid subscription plans. Subscriptions are per-product — a subscription to one product does not grant access to paid features of other products. By subscribing:
- You authorize us to charge the applicable subscription fee to your payment method on a recurring basis.
- Subscription fees are billed in advance on a monthly or annual basis and are non-refundable except as required by law.
- You may cancel your subscription at any time. Cancellation takes effect at the end of the current billing period.
- We reserve the right to change subscription pricing with 30 days notice.
3. Free Tier
Certain products offer a free tier with limited functionality. For OptiCoat Designer, the free tier includes: 1 layer stack, up to 3 layers per stack, 1 saved design, basic reflectivity and transmission charts, D65 illuminant only, and 0° angle analysis. Recipe Tracking, Yield Analysis, the Design Optimizer, and AI features are not available on the free tier. We reserve the right to modify free tier limits at any time.
4. AI-Powered Features
Some products include AI-powered features (such as the Lumi AI Assistant in OptiCoat Designer). By using these features, you acknowledge that:
- AI-generated responses are provided for informational and assistive purposes only. They do not constitute professional engineering advice.
- You are solely responsible for verifying and validating any suggestions, calculations, or recommendations provided by AI features before relying on them.
- We make no guarantees regarding the accuracy, completeness, or suitability of AI-generated content for any particular purpose.
- AI features may be modified, rate-limited, or discontinued at our discretion.
5. Acceptable Use
You agree not to misuse our services. This includes but is not limited to: attempting to gain unauthorized access, interfering with service operations, using the service for illegal purposes, reverse-engineering our software, or attempting to manipulate AI features to produce harmful or misleading content.
6. Intellectual Property
Our products, including all code, designs, and documentation, are owned by Cor Stellaris LLC and protected by intellectual property laws. Your subscription grants you a limited, non-exclusive, non-transferable license to use the product for its intended purpose.
7. Your Content
You retain ownership of all designs, data, and content you create using our products. We do not claim any rights to your content. We will not share, sell, or use your content for purposes other than providing the service.
8. Service Availability
We strive to maintain high availability but do not guarantee uninterrupted service. We may perform maintenance, updates, or experience outages. We are not liable for any losses resulting from service interruptions.
9. Limitation of Liability
To the maximum extent permitted by law, Cor Stellaris LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, or goodwill.
10. Changes to Terms
We may update these Terms from time to time. We will notify you of material changes via email or through our products. Continued use of our services after changes constitutes acceptance of the updated Terms.
