Using this website
You may browse and use this website for lawful personal or business purposes. You must not attempt to bypass security, gain unauthorised access, disrupt the service, submit malicious material, scrape the site at a level that impairs service, or misuse its content or forms.
Information, demonstrations and professional advice
Website content is general information and may be changed or withdrawn. It is not engineering, safety, pharmaceutical, legal, financial or other professional advice for a specific situation. Demonstrations, calculators, models, forecasts and digital twins are illustrative unless a written agreement expressly says otherwise. They must not be used as the sole basis for a regulated, safety-critical or operational decision.
Engagements and purchases
Sending a contact form does not create a client relationship, duty of care or contract. A consulting or software engagement begins only when the relevant parties accept written terms. The site does not currently take payment or activate customer accounts. Specific sales, licence, cancellation and refund terms will be shown before any direct online purchase becomes available.
Intellectual property
Unless stated otherwise, DRJS owns or is licensed to use the website's text, branding, layouts, graphics, demonstrations and original code. You may link to public pages and quote short extracts with clear attribution. You may not reproduce, resell, remove ownership notices from, or create a competing product from substantial parts of the site without written permission. Third-party names and marks remain the property of their owners.
External services and availability
Links to external sites are provided for convenience and demonstration. DRJS does not control their content, security, accessibility or privacy practices. Reasonable care is taken to keep the website available and accurate, but uninterrupted access and freedom from every error cannot be guaranteed.
Liability
Nothing in these terms excludes liability that cannot lawfully be excluded, including liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation. Subject to that, DRJS is not responsible for loss caused by reliance on general website information, use of an illustrative demonstration, an external site, or events outside reasonable control. Any liability arising under a separately contracted service or product is governed by that contract.
Privacy, changes and contact
Personal information is handled as described in the privacy notice. DRJS may update these terms as the website develops; the date shown on this page identifies the current version. Use the homepage contact form for a question about these terms.
