Terms of Service
Last updated November 2026
These terms are an agreement between Symphia LLC (“Symphia,” “we,” “us”) and the person or organization using Lumen and its website at lumen.symphia.ai (the “Service”). By using the Service you agree to them. If you use the Service for an organization, you confirm you may bind it, and “you” means that organization. A signed agreement with us takes priority where it differs.
1. The Service
Lumen is a hotel property management system. Subject to these terms, we give you a limited, non-exclusive, non-transferable right to use it for your hotel's internal business.
2. Accounts
You are responsible for your account, for keeping access to your email secure, and for what happens under your account. Tell us promptly at support@symphia.ai if you suspect unauthorized access.
3. Early access
Lumen is in early access and is not generally available. It may change, contain errors or be withdrawn at any time. There are no service-level or availability commitments.
While a hotel runs read-only beside its property management system, that system remains the system of record. Do not rely on Lumen as the only source of information for operating your hotel, for accounting or for tax.
4. Connecting your hotel
If you connect a property management system, you confirm that you are allowed to give us access to it and to the data in it, and that you have given any notices and have any permissions the law requires for that data.
5. Acceptable use
- Don't break the law or infringe anyone's rights using the Service.
- Don't try to access other hotels' data or systems you aren't authorized to use.
- Don't probe or test the Service's security without our written permission, except to report a problem to us in good faith.
- Don't reverse engineer or resell the Service, or interfere with how it runs.
6. Your data
You keep all rights to your data. You give us permission to host and process it only to provide, secure and improve the Service for you. See our Privacy Policy.
7. Fees
These terms don't set any fees. If fees apply to your use of Lumen, they will be agreed with you in writing first.
8. Our intellectual property
Symphia owns the Service, including its software, design and the Lumen name. If you send us feedback, we may use it without restriction or payment.
9. No warranties
To the maximum extent the law allows, the Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including merchantability, fitness for a particular purpose and non-infringement. We don't promise that the Service will be uninterrupted or error-free, or that the information shown in it is complete or current.
10. Limit of liability
To the maximum extent the law allows, neither party is liable for indirect, incidental, special or consequential damages, or for lost profits, revenue or data. Symphia's total liability relating to the Service will not exceed the greater of the amounts you paid us for the Service in the previous twelve months or one hundred US dollars.
11. Ending your use
You may stop using the Service at any time. We may suspend or end your access if you break these terms, if there is a risk to the Service or others, or if we withdraw the early-access program. When your access ends we will remove your hotel's data on request, subject to any legal duty to keep it.
12. Governing law
These terms are governed by the laws of the State of California, without regard to conflict-of-law rules. The state and federal courts in San Francisco County, California, have exclusive jurisdiction, except that either party may seek injunctive relief in any competent court.
13. Changes and general terms
We may update these terms and will change the date above when we do. If a provision can't be enforced, the rest still apply. You may not assign these terms without our consent. Neither party is liable for delays caused by events beyond its reasonable control.
