Terms of Service

Supplier: Lumen Apps, registered with the Chamber of Commerce under number 75253070.

Client: The natural person or legal entity that enters into an agreement with the Supplier.

Services: All services offered by the Supplier, including:

• Web and mobile application development
• Technical advice and consultancy
• Support, maintenance and project execution

Project: The work as described in the quotation or agreement between Supplier and Client.

Deliverables: All software, source code, configurations, documentation and other materials delivered by the Supplier to the Client as part of the Project.

Additional Work: Work or services performed by the Supplier that fall outside the scope of the original agreement.

Written: Communication by email, letter or other durable medium acknowledged as such by both parties.

These Terms of Service form part of the quotation and the final agreement. By accepting the quotation, paying an invoice, or providing materials, the Client confirms having fully read and accepted these terms.

Changes or additions to these terms are only valid if recorded in writing and agreed upon by both parties.

Prior to project start, a discovery call takes place to determine whether the project is a good fit for both parties.

Each project is evaluated individually to determine the most suitable architecture. We specialize in modern, high-performance technologies and select the best tools for each unique situation. Our expertise spans, but is not limited to:

• TypeScript, React, and Next.js for scalable, robust web applications
• Swift and SwiftUI for native iOS development
• React Native for cross-platform mobile applications
• Backend-as-a-Service (BaaS) platforms such as Convex, Supabase, and Firebase
• Cloud infrastructure providers including Cloudflare, Vercel, Railway, and AWS
• Payment integrations like Stripe, Creem, Polar, and Mollie
• AI and automation integrations where applicable

We are not tied to any single platform or provider. The specific technology stack for each project is discussed and agreed upon during the discovery phase, ensuring we always choose the exact tools that guarantee speed, scalability, and cost-efficiency for your product.

Payment is made in installments:

• 30% at project start
• 60% after delivery of the first functional version
• 10% after final approval and delivery

Invoices must be paid within 14 days of the invoice date.

Additional work outside the original project scope will be discussed in advance and invoiced separately.

Upon project start, resources are immediately allocated including planning, infrastructure setup, and third-party services. For this reason, refunds are handled as follows:

Before project start: Full refund possible.

After project start: A partial refund of up to 10% of the total project price may be considered, minus any work already performed and costs incurred.

After delivery of the first functional version: No refund possible, as significant work has been completed.

After full payment, the Client becomes the exclusive owner of the custom Deliverables, including source code, configurations, and project documentation.

Until full payment is received, all Deliverables remain the property of the Supplier.

Standard components, frameworks, and development methodologies remain the property of the Supplier and may be used in other projects.

The Supplier retains the right to showcase the Project in its portfolio, unless otherwise agreed in writing.

For successful project execution, the Client agrees to:

• Provide all necessary information, materials, and feedback in a timely manner
• Be available for scheduled meetings and review sessions
• Respond to questions and requests within a reasonable timeframe

If the Client does not meet agreed-upon deadlines for feedback or materials, this may affect the project timeline. The Supplier will communicate proactively if delays occur.

After delivery of the Deliverables, the Client has 14 days to test functionality (acceptance period).

After written acceptance, a 30-day warranty period applies during which the Supplier fixes defects that prevent the software from functioning as described in the project agreement, free of charge.

Defects must be reported in writing within the warranty period. Issues caused by improper use, changes by the Client or third parties, or external factors are excluded from the warranty.

If agreed, the Supplier provides maintenance and support, including technical assistance and resolution of minor issues.

Support is available on working days from 09:00 to 17:00 (CET), with a response time of up to 24 hours for non-urgent requests.

Ongoing support and maintenance can be arranged through a separate agreement.

The Supplier is liable for direct damages due to an attributable breach, up to a maximum equal to the amount paid by the Client for the Project.

Indirect damages (including lost profits or consequential loss) are excluded.

The Supplier is not liable for issues arising from third-party services, hosting providers, or changes made by the Client after delivery.

Both parties may terminate the agreement with 30 days written notice.

Upon termination, the Supplier delivers all completed work to the Client, provided payment for work performed has been made.

The Supplier may immediately terminate the agreement in case of non-payment after written reminder.

In case of disputes, parties will first attempt to resolve the matter through good faith negotiation.

Dutch law applies to all agreements. The competent court is Rotterdam.

These terms, together with the quotation and any additional written agreements, constitute the entire agreement between the parties.

The Supplier may amend these terms with written notice. Changes take effect 30 days after notice.

If any provision is void or unenforceable, the remaining provisions remain in force.
