Terms
The deal between us. Short and fair.
These terms apply to using this website and to any project we agree on. The detail of a specific project lives in the statement of work, these are the baseline rules.
Last updated: 7 September 2026
02 — This website
Use it for what it's for.
You're welcome to browse, read and share this site. Don't scrape it at volume, don't probe it for vulnerabilities without permission, and don't try to impersonate us. We provide the site as‑is; we make no warranty that it is always available or that the content is suitable for your specific situation.
03 — Projects
Every project gets its own statement of work.
When we agree to work together we write a short statement of work (SOW) that names the deliverable, the acceptance criteria, the start date, the delivery date, the fixed price and the way we end the project. The SOW takes precedence over anything on this site. Until an SOW is signed, no obligation exists between us beyond a normal conversation.
04 — Price and invoicing
A fixed price per deliverable.
We work on a project basis, not on an hourly basis. Each deliverable is specified and priced before work on it starts, and that price is what you pay. Unless the SOW says otherwise we invoice half on start and half on acceptance, payable within fourteen days. AI token costs are bought directly from the provider and passed through at cost, without a margin. Other out‑of‑pocket expenses (travel, third‑party services) are billed at cost with prior approval. VAT is added where applicable.
05 — Intellectual property
You own what we build for you.
On payment, all work product we create specifically for your project (code, designs, documents) transfers to you. We retain the right to reuse generic skills, methods, and pre‑existing tools and components. Open‑source components remain governed by their own licences.
06 — Confidentiality
Your business is your business.
We treat non‑public information you share with us as confidential and use it only for the project. This obligation survives the end of the project for three years. We may name you as a client in a brief portfolio reference unless you ask us not to.
07 — Liability
Capped at the price of the deliverable.
We do our work with reasonable care and skill. Our total liability for any claim arising from a project is capped at the price of the deliverable the claim relates to. We are not liable for indirect, consequential, or lost‑profit damages. Nothing in these terms limits liability that cannot be limited under Dutch law.
08 — Ending a project
Thirty days' notice, either side.
Either of us may end a project on thirty calendar days' written notice. We invoice for deliverables completed and accepted, plus a pro‑rated share of any deliverable in progress. We hand over files, credentials and a short transition note so your team can pick up where we left off.
09 — Governing law
Dutch law, Amsterdam court.
These terms and any project are governed by the laws of the Netherlands. Disputes go to the competent court in Amsterdam, unless mandatory consumer law says otherwise.
10 — Changes
We may update these terms.
We may update these terms from time to time. The version dated at the top of this page applies to website use. For an active project, the version of the terms attached to your SOW continues to apply for the duration of that project.
