Terms of use
The rules for using this website.
Last updated: 2 August 2026 ยท Version 1.0
Scope
These terms govern the use of this website. It is an information site written for private households. Nothing is sold here.
Nature of the content
All guides and figures are editorial guidance. They are not technical, tax or legal advice and they do not replace a site survey or a consultation for your individual case.
Calculator results
Every calculator result is an estimate produced from the assumptions shown on screen. Changing an assumption changes the result. Results are not offers, not yield forecasts and not guarantees.
Accuracy and availability
We prepare content with care and date every figure, but we cannot warrant that it is complete, free of error or current at all times, and we cannot warrant uninterrupted availability of the site.
External links
Links to third party sites are provided for reference. We do not control their content and a link is not an endorsement. Responsibility for those pages lies with their operators.
Rights in our content
The texts, graphics, calculators and layout of this website are protected. Private use and quotation with a source reference are permitted. Any other reproduction or commercial use requires our prior written consent.
Enquiries through our funnel
If you start an enquiry, you leave this website for our own funnel. What happens there is governed by the terms and the privacy information shown in that funnel.
Governing law and jurisdiction
Swiss law applies. The place of jurisdiction is Basel-Landschaft, Switzerland, unless mandatory consumer protection law of your country of residence provides otherwise.
