These Terms of Service ("Terms") govern your use of the website at langesoftware.com, the
LUCY chat-assistant platform, and any development or consultancy services provided by Lange Software
Solutions ("we", "us", "our"). By using the site, engaging our services, or running a LUCY installation,
you agree to these Terms. If you do not agree, do not use the services.
Lange Software Solutions is a sole-trader software consultancy based in Edinburgh, Scotland, United Kingdom, run by Hubert Lange. Contact: hubert@langesoftware.com.
We design and build websites, e-commerce stores, mobile apps, AI booking assistants and automations. Specific deliverables, timelines and fees for any engagement are set out in a separate written proposal or statement of work, which forms part of the agreement between us. Where a proposal conflicts with these Terms, the proposal governs for that engagement.
If you engage us, you agree to:
On full payment for an engagement, ownership of the bespoke deliverables created specifically for you transfers to you, except for: (a) third-party components and open-source libraries, which remain under their own licences; and (b) our pre-existing tools, frameworks and the LUCY platform itself, which remain our property and are licensed to you for use as part of the service. The "Lange Software Solutions", "LSS" and "LUCY" names and logos are ours and may not be used without permission.
When using the site or the LUCY platform, you must not:
LUCY is an AI assistant powered by third-party AI models. It can make mistakes and its output should not be relied on as professional advice. For customers running a LUCY installation: you are the data controller for your end-users' data, we are your processor, and a separate data processing agreement applies. We may apply reasonable rate limits and abuse protections, and may suspend an installation that threatens the security or stability of the platform.
Nothing in these Terms excludes or limits liability that cannot lawfully be excluded — for example, liability for death or personal injury caused by negligence, or for fraud. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
We respect intellectual property rights. If you believe content made available through our services infringes your copyright, you can submit a notice under the US Digital Millennium Copyright Act. Our full takedown and counter-notice procedure, repeat-infringer policy and designated agent details are on our DMCA / Copyright page.
These Terms apply while you use the services. Either party may terminate an engagement as set out in the relevant proposal. We may suspend or end access to the site or the LUCY platform if these Terms are breached. Sections that by their nature should survive termination — including intellectual property, disclaimers, limitation of liability, governing law and dispute resolution — survive.
If you are resident in, or your principal place of business is in, the United States: these Terms are governed by the laws of the State of Delaware and the Federal Arbitration Act, without regard to conflict-of-laws rules, and disputes are resolved as set out in section 13.
If you are anywhere else (including the UK, EU and rest of world): these Terms are governed by the laws of Scotland, and the courts of Scotland have exclusive jurisdiction, except that we may bring proceedings to recover unpaid fees in the courts of your place of residence or business.
This section applies only to users resident in the United States. It does not apply to users in the UK, EU or elsewhere, who are covered by section 12.
You and Lange Software Solutions agree that any dispute, claim or controversy arising out of or relating to these Terms or the services will be resolved by binding individual arbitration, rather than in court, except that either party may bring an individual claim in small-claims court. Arbitration will be administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules. The Federal Arbitration Act governs the interpretation and enforcement of this section.
You and we agree that each may bring claims against the other only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated or representative proceeding. The arbitrator may not consolidate more than one person's claims and may not preside over any form of a representative or class proceeding.
You can opt out of this arbitration agreement and class-action waiver within 30 days of first accepting these Terms by emailing hubert@langesoftware.com with the subject line "Arbitration Opt-Out" and your name. Opting out will not affect any other part of these Terms, and we will not terminate your access for opting out. If you opt out, the governing-law and jurisdiction rules in section 12 for non-US users apply to you instead.
Before starting arbitration, you agree to first contact us and give us 30 days to resolve the dispute informally. Most concerns can be sorted out this way.
We may update these Terms from time to time. We'll update the version number and "Last updated" date at the top. Material changes to the arbitration section will not apply retroactively to disputes we already have notice of. Continued use of the services after an update means you accept the revised Terms.
