Terms of Service (ToS)

1. Introduction and Acceptance of Terms

1.1. Company Identity

These General Terms and Conditions (hereinafter referred to as the "Terms of Service" or "ToS") govern all commercial, legal, and contractual relationships between Only One Concept LLC, a limited liability company registered in the State of Wyoming, United States (hereinafter referred to as the "Company", "We", or "Service Provider"), and any professional entity (hereinafter referred to as the "Client") browsing the website, purchasing digital products, or subscribing to any design, development, or consulting services.

1.2. Strict B2B (Business to Business) Nature of the Contract

All services, digital products, and deliverables provided by Only One Concept LLC are strictly reserved for professionals (including, but not limited to, development studios, escape game creators, architects, businesses, and independent contractors). By accepting these ToS, the Client expressly certifies that they are acting within the scope of their commercial, industrial, artisanal, or professional activity. Consequently, legal provisions relating to consumer protection (B2C) are not applicable to this contract.

1.3. Acceptance of Terms

Browsing this website, purchasing a product on our stores (including partner platforms such as Fab or Epic Games), and signing any quote constitute full, unconditional, and unreserved acceptance of these ToS by the Client. No purchasing terms or specific conditions provided by the Client shall prevail over these ToS without the formal, explicit, and written consent of Only One Concept LLC.

2. Definitions

To ensure a clear and unambiguous understanding of this contract, the following terms, when capitalized, shall have the meanings set forth below:

Client: 

Any individual or legal entity, acting strictly in a professional capacity, requesting the services of Only One Concept LLC or acquiring any of its products.

Project: 

All custom services (Technical Design, Video Game Development, Consulting) defined, estimated, and jointly validated by the Client and the Company within a formal quote.

Deliverables: 

The final export files provided to the Client upon completion of a service (including, but not limited to, DXF/STEP cutting files, PDF plans, or Blueprint integrations).

Source Files: 

The native, raw, and editable work files generated by the Company during its creative process (e.g., complete CAD projects, base design files). Unless explicitly stated otherwise in the contract, these files remain the exclusive property of the Company and are never provided to the Client.

Milestones: 

The intermediate and successive validation steps defined during a custom Project. The validation of each milestone locks the previous phase and is a strict prerequisite for the continuation of the Project.

Assets: 

Pre-designed digital products, modular systems, and models sold "as is" on the Company's store or via third-party distribution platforms.

3. Orders and Project Management (Custom Services)

3.1. Contract Formation and Validity of Quotes

All custom Projects (Blueprint development, 3D model design, consulting) are subject to a prior free quote issued by the Company. Unless otherwise stated, quotes are valid for a period of thirty (30) calendar days from their date of issue.

The order is only considered firm, final, and binding upon the strict fulfillment of the following two conditions:

- Receipt of the quote dated and signed by the Client (digital validation acting as a manual signature).

- The actual clearing of the upfront deposit (as defined in Section 4) into the Company's bank account.

No preparatory work or scheduling will begin before these two conditions are met.

3.2. Scheduling and Estimated Deadlines

Given the highly technical, iterative, and custom nature of the design and development services, all delivery times or production schedules communicated by the Company are provided on a strictly estimated basis.

The Company agrees to make every reasonable effort to meet the estimated dates. However, exceeding these estimated deadlines shall in no event justify the cancellation of the order by the Client, justify a claim for damages, or give rise to financial penalties or withholdings against Only One Concept LLC.

3.3. Client's Obligation to Cooperate and Responsiveness

The successful execution of the Project requires active collaboration from the Client. The Client agrees to provide the Company, within the allotted timeframes, with all required materials (architectural plans, specifications, environmental dimensions, access to code repositories, etc.) and to proceed with the validation of intermediate Milestones without undue delay.

In the event of a failure to provide the required materials or a lack of feedback on a Milestone validation for a consecutive period exceeding fourteen (14) calendar days, the Company reserves the right to temporarily suspend the Project. The reactivation of the Project will then occur exclusively according to the Company's future schedule and availability, releasing the Company from any liability regarding the overall delay caused to the Client's schedule.

4. Financial Terms and Payment Modalities

4.1. Pricing, Currencies, and Taxes

All prices indicated on the quotes or the Company's stores are exclusive of taxes (HT). To facilitate international transactions, the Company is able to issue its quotes in the Client's reference currency (notably USD, EUR, AUD).

As the Company operates exclusively B2B from the State of Wyoming, the payment of any applicable local tax, VAT (notably via the reverse charge mechanism for European companies), or potential customs duties is the exclusive and full responsibility of the Client, according to the legislation in force in their country of residence. Payments must be made by bank transfer to the international coordinates provided on the invoice, with the wire transfer issuance fees (notably SWIFT fees) remaining the responsibility of the Client.

4.2. Billing Structure

Unless a specific contractual agreement is explicitly stated in writing in the quote, payment for custom Projects is made according to the following schedule:

Upfront Deposit: 

Fifty percent (50%) of the total amount (including taxes, if applicable) due upon signature of the quote. This deposit is strictly non-refundable and covers the Company's mobilization, research, and audit costs.

Balance: 

Fifty percent (50%) of the total amount due upon validation of the final Milestone or upon delivery of the Deliverables. This balance is payable upon receipt of the final invoice, with a maximum payment term set at fifteen (15) calendar days.

4.3. Late Payments and Collection

Compliance with payment deadlines is an essential condition of this contract. In the event of total or partial non-payment of an invoice by its due date, and without any prior formal notice being required, the following sanctions will apply by right:

Late Penalties: 

Application of an interest rate equivalent to 1.5% per month of delay, calculated on the total outstanding amount.

Fixed Indemnity: 

A fixed indemnity for collection costs of $50 USD (or €40 EUR, depending on the billing currency) will automatically become due on the first day of delay.

Suspension of Services and License Revocation: 

The Company reserves the absolute right to immediately suspend any work in progress (design, development, consulting). Furthermore, any payment delay results in the immediate and temporary revocation of the license for use associated with the Deliverables. Any commercial, technical, or physical exploitation of the files, models, or source code by the Client or their subcontractors during this period shall be considered an intellectual property violation.

Legal Fees: 

If the Company is forced to resort to a third party (law firm, collection agency, bailiff) to obtain payment of the amounts due, the entirety of the costs incurred for this collection procedure shall be fully billed to the defaulting Client.

5. Specific Conditions per Activity Branch

5.1. Technical Design Division (Custom Design and Store)

Milestone Methodology: Custom design services (particularly for escape game structures) are subject to a strict iterative validation process divided into three milestones: (1) Volume validation based on provided dimensions, (2) Systems and mechanics validation, (3) Aesthetics validation. Any request for a major modification impacting a milestone previously validated by the Client will be subject to additional billing.

Physical Liability Exemption: The provided Deliverables (plans, DXF/STEP cutting files) constitute digital prototypes based exclusively on the dimensions and information transmitted by the Client or their architects. The Company disclaims all liability regarding manufacturing errors, the mechanical resistance of the materials chosen during machining, or on-site adjustment issues related to defects in the physical environment (uneven walls, irregular floors).

Plan Store: Plans and designs purchased directly from the Company's store are sold "as is" and on a firm and final basis. Designs labeled as "Theoretical" (Orange Badge) have not been subjected to physical testing under real conditions, and the Client assumes all risks associated with their manufacturing and integration.

5.2. Video Game Development Division

Modular Development: Software development services are performed in Unreal Engine 5 and rely on a modular Blueprint architecture (overlay or "Actor Components"). The Company agrees not to alter the Client's original source code.

Integration Responsibility: The Company's responsibility is strictly limited to delivering a functional and isolated system. The final integration of the system into the Client's host project, as well as the creation of data communication interfaces (Event Dispatchers, UI), are exclusively the Client's responsibility. The Company cannot be held liable for conflicts, crashes, or performance drops caused by incompatibilities with the Client's code or third-party plugins.

Engine Scalability: The Company does not guarantee maintaining the Deliverables' compatibility with future updates to the Unreal Engine deployed after the delivery date. Any compatibility update will require the establishment of a new quote.

5.3. Consulting & Remote Monitoring Division

Subscription Model (Retainer): Site monitoring or technical mentoring services billed as a monthly retainer grant the Client a predefined quota of hours.

Consumption of Hours: Unused hours at the end of the monthly billing period are definitively forfeited and cannot under any circumstances be carried over to the following month.

Scheduling: Any support session must be scheduled in advance with a minimum notice of twenty-four (24) hours. The Company reserves the right to refuse emergency intervention requests that do not respect this notice period.

5.4. Digital Asset Sales (Digital Store, Fab, Epic Games)

Purchases of digital Assets made via third-party distribution platforms (such as Fab or the Epic Games Marketplace) are exclusively governed by the End User License Agreements (EULA) and terms and conditions of sale of these platforms.

In this context, the Company's website acts merely as a redirection showcase. Any downloadable digital product is considered consumed upon acquisition and is not subject to any refund or withdrawal policy.

6. Intellectual Property and Licenses for Use

6.1. Exclusive Retention of Intellectual Property

Unless otherwise expressly stipulated in writing in the quote, Only One Concept LLC remains the exclusive and absolute owner of all intellectual property rights related to its creations, including, but not limited to, codes, Blueprints, 3D models, Source Files, mechanical schematics, and methodologies developed during the Project.

The Client acknowledges that they acquire no ownership rights to the native Source Files, as the Company's only obligation is the delivery of the final export Files (Deliverables).

6.2. Grant of License for Use

Subject to full payment of the amounts due, the Company grants the Client a personal, non-exclusive, non-transferable license for use limited to the specific Project defined in the quote (for example, installation for a single escape game room or integration into a single video game).

Any reproduction, resale, distribution, or exploitation of the design for a franchised project, or the reuse of code for third-party projects, is strictly prohibited without the prior negotiation of a commercial license extension.

6.3. Use of Artificial Intelligence

The Client is informed and agrees that the Company may use generative Artificial Intelligence (AI) tools in its ideation, code optimization, or content creation process. The final Deliverables resulting from this process remain subject to the same ownership and license terms as all of the Company's creations.

7. Confidentiality and Right of Citation (NDA)

7.1. Confidentiality Commitment

The Company agrees to treat as strictly confidential all information, documents, game scenarios, secret mechanics, and industrial plans transmitted by the Client. These data will be used exclusively for the realization of the Project and will not be disclosed to any third party without the Client's prior consent.

7.2. Right of Citation and Portfolio

Unless explicitly refused in writing by the Client prior to the signing of the quote (which may be subject to specific billing for a "White Label Clause"), the Company reserves the right to mention the Client's name, display their logo, and present non-confidential images or videos of the Project on its website and social networks for promotional purposes, solely after the public release or official inauguration of the project by the Client.

8. Warranties and Limitation of Liability

8.1. Obligation of Means

The Company is bound by an obligation of means (best efforts) in the execution of its design, development, and consulting services, and not by an obligation of result. No warranty is provided regarding commercial success, increased traffic, or financial profitability generated by the integration of the Company's creations.

8.2. Third-Party Dependency

The Company shall under no circumstances be held liable for damages, bugs, delays, or financial losses resulting from a change in policies, a software update, or a technical failure imposed by a third party (including, but not limited to, Epic Games, Fab, CAD software, web hosts, or manufacturing facilities selected by the Client).

8.3. Liability Cap

In the event the Company's liability is invoked by the Client for any reason whatsoever (including negligence or breach of contract), the maximum amount of damages that may be claimed against Only One Concept LLC shall be strictly limited to the total amount exclusive of tax (HT) actually paid by the Client for the specific service that caused the alleged damage. The Company shall never be held liable for indirect damages (including loss of business, loss of data, and loss of revenue).

9. Force Majeure and Termination

9.1. Force Majeure

The Company shall not be held liable for a delay or failure to perform its contractual obligations if such failure is caused by a force majeure event (including natural disasters, pandemics, major telecommunication network outages, strikes, or severe illness).

9.2. Early Termination by the Client

In the event of cancellation or unilateral termination of the contract by the Client during an ongoing Project, the initial upfront deposit remains vested by right to the Company. Furthermore, any work completed or in progress at the time of cancellation will be billed on a pro-rata basis for the time invested and must be paid within fourteen (14) days.

10. Governing Law and Jurisdiction

These Terms of Service, as well as all contracts and quotes concluded by the Company, are governed and interpreted exclusively in accordance with the laws of the State of Wyoming, United States, without regard to conflict of law principles.

In the event of a dispute relating to the validity, interpretation, or execution of this contract, and failing an amicable resolution within a period of thirty (30) days, the competent courts of the State of Wyoming (USA) shall have exclusive jurisdiction.
