Enquiries and quotes

You cannot buy anything or enter into a contract through this website. Sending an enquiry and the first call are free and without obligation. An order only comes about once you confirm my written quote. It sets out the fixed price, the scope and the binding delivery date.

Prices on this website

Prices on this website are in Swiss francs, excluding VAT, as of October 2026. Most of them are ‘from’ prices. Where there is no ‘from’, it is a fixed price. They show you what to expect before we first talk. The price in your quote is the one that counts.

Liability for content

I take care to keep the content of this website up to date. Even so, a detail may be missing, wrong or out of date. To the extent permitted by law, I accept no liability for any damage arising from the use of this information.

The guides on this website explain things in plain words, for example what a website costs or what data protection means for your contact form. They are not a substitute for legal or tax advice.

Links to other websites

Some links lead to websites run by others, for example to my own projects. Whoever runs those websites is responsible for their content. I checked each linked page when I added the link. If I learn that a link leads to unlawful content, I remove it straight away. A short note to [email protected] is all it takes.

Copyright

The text, images, graphics and code on this website are protected by copyright and belong to Sven Zanstra, unless stated otherwise. If you would like to use any of it, you need my written permission first. A short e-mail is enough.

Images: screenshots from Sven Zanstra's own projects.

With your project, it is the other way round: what I build for you belongs to you after handover. Website, code and domain. The details are set out in the quote.

How I handle your data is explained in the privacy policy.
