Terms & Conditions

MainArc is a side project run by one human (the founder) and one AI agent, with no team, office, or investor behind it, and by using the site, downloading the free products, or hiring us for paid work, you are agreeing to these terms; close the tab if you do not agree. The site is open to read, link, share, and quote with attribution, but please do not scrape it, mirror it, feed it to an AI model for training, or try to break things, and if you do we will quietly block your access. Everything we publish for free (Design MBA, Craftkit, Taste MBA, Ceiling, AI Native Guide, the research issues, the newsletter) is one person's opinions and research at one moment in time, not legal or financial or business advice, may be wrong or outdated or both, and we reserve the right to update, change, or retire any of it at any time for any reason including "I changed my mind." When we take on paid work, it runs on a signed proposal (half upfront, half on delivery, non-refundable once done), delivery dates are estimates that shift if you delay feedback, we may use subcontractors or AI tools and remain responsible for the final work either way, and either side can end the engagement with reasonable notice while you pay for what was done up to that point. On AI, the section that matters most: we use it across almost everything we do, from research to writing to design to code to remembering what we are supposed to be doing on a Tuesday, which means our outputs occasionally hallucinate, sometimes resemble other works in their training data, and may not be copyrightable wherever you happen to live; we review the work before sending it out, but if you plan to use anything we make in regulated, public, financial, or otherwise high-stakes settings, you are responsible for fact-checking, verification, and legal clearance before it goes live, and please do not send us anything you are not allowed to share with third-party AI tools, because assume it might end up processed by one. On ownership, the short version is that we keep the systems (name, brand, frameworks, methods, prompt systems, templates, research, anything we built before working with you, and the lessons we learn along the way) and you keep the work (a permanent worldwide license to use deliverables in your business, modify them, share them within your team, and use them commercially, though without the right to resell our frameworks separately or to assert IP on AI-generated portions that may not be copyrightable in your country), you own everything you give us, and we can talk about the work in our portfolio and case studies unless you ask us in writing not to. We promise to do the work with reasonable care and competence, the standard you would expect from a thoughtful professional who is awake, but we do not promise specific business outcomes, perfect uptime, error-free AI output, fit for use cases you did not tell us about, or accuracy of free content; if something is broken or off, tell us within fourteen days and we will fix it or refund the relevant part. Liability for paid work is capped at the fees you paid us in the prior three months or USD 500, whichever is higher, liability for free use is capped at USD 50 (which feels fair given that you paid us nothing), we are not liable for indirect or consequential losses including lost profits or business interruption, and any claim is brought against MainArc the project, with the founder, the AI agent, and anyone helping protected from personal claims. If you misuse our work or bring trouble to our door (IP claims rooted in materials you gave us, regulatory fallout from using us in high-stakes settings without your own checks, third-party legal claims), you handle it and cover the cost. Either side can end this anytime (you by stopping, us by closing your access for cause), applicable law governs, disputes start with an honest email and a follow-up call and only reach formal proceedings if that fails, no class actions because we are far too small for one to make any sense, and the protective sections (AI, ownership, privacy, liability, misuse) survive termination because that is what they are for. If we change these terms, the date at the top updates and the new version goes on the site; for ongoing paid work, the version we signed under continues to apply. Reach us for anything, and write "urgent" in the subject if it actually is. The English version of this document controls.
