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.

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.
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.
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. Hosting works the same way: we can arrange it, but the account is yours and the provider bills you. Other out‑of‑pocket expenses (travel, third‑party services) are billed at cost with prior approval. VAT is added where applicable.
Building something and keeping it running are separate undertakings. We can arrange the hosting and help you deploy onto it, in the EU or elsewhere, and that help is part of the project. The account stays in your name and the provider invoices you directly, so hosting is never inside our fixed price. If you want us to monitor or maintain the software afterwards we agree that separately, with its own scope, fee and notice period. Without such an agreement we are not responsible for uptime, backups or incident response once a deliverable is accepted.
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.
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 one year. We work for other clients at the same time, including in your own sector, and nothing here stops us doing so. What we never carry across is your confidential information. We may name you as a client in a brief portfolio reference unless you ask us not to.
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.
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.
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.
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.
