Terms of Service
Last updated: 22 July 2026
These Terms of Service (the "Terms") govern your access to and use of AppNGen — the websites at appngen.ai, studio.appngen.ai and account.appngen.ai, and the software services available through them (together, the "Service"). The Service is operated by AppNGen ("AppNGen", "we", "us"), a business based in the United Kingdom. By creating an account or using the Service you agree to these Terms. If you do not agree, do not use the Service.
1. The Service
AppNGen turns a plain-language description into a planned, built and deployed software application. The Service includes AI-assisted planning, design and code generation; a git-backed workspace for each project; build and test infrastructure ("sprints"); live previews of your application; and optional deployment of your application to hosting we operate or to destinations you configure.
Generation is performed by machine-learning models. Output is probabilistic: we do not promise that any particular build will succeed, that generated code will be free of defects, or that it will be fit for any particular purpose. You are responsible for reviewing and testing anything you deploy or rely on.
2. Accounts
You must provide accurate registration information, keep your credentials confidential, and be at least 18 years old (or the age of legal majority where you live) to use the Service. You are responsible for all activity under your account. Tell us promptly at support@appngen.ai if you believe your account has been compromised.
3. Plans, credits and billing
The Service is offered on the plans described on our pricing page, which forms part of these Terms: a free tier, pay-as-you-go credit top-ups, and monthly subscriptions (currently Core and Pro). Build credits are consumed by usage as described at checkout and in-product; prepaid pay-as-you-go credits do not expire, but credits are not redeemable for cash and are non-transferable. Prices, plan features and limits may change; changes apply from your next billing cycle. Payments are processed by our payment providers (see the Privacy Policy). Where required by law you may have statutory cancellation rights; otherwise fees are non-refundable except as expressly stated.
4. Acceptable use
You agree not to use the Service to:
- build, host or distribute anything unlawful, or infringe anyone's rights (including intellectual-property, privacy and data-protection rights);
- create or spread malware, phishing pages, spam infrastructure, or content designed to deceive or defraud;
- probe, scan, or attempt to breach the isolation of our infrastructure, access other customers' workloads or data, or interfere with the operation of the Service;
- mine cryptocurrency, run workloads unrelated to building and previewing your applications, or deliberately circumvent resource limits, plan limits or metering;
- resell or provide the Service to third parties as your own service without our written agreement.
We may suspend or limit access, remove content, or terminate accounts that we reasonably believe breach this section.
5. Your content and intellectual property
You own your project. As between you and AppNGen, you retain all rights in the material you submit (prompts, briefs, assets, code) and in the application code, designs and other output generated for you by the Service ("User Content"). To the extent AppNGen holds any rights in generated output, we assign them to you on creation, subject to payment of any applicable fees. You can export your repository at any time.
You grant us a non-exclusive, worldwide licence to host, store, reproduce, transmit and process User Content solely as needed to operate, secure and improve the Service — including passing prompts and code to the model providers that perform generation on our behalf. We do not claim ownership of your applications.
The Service itself — our platform, agents, prompts, templates, branding and documentation — remains the property of AppNGen and its licensors. Generated output may resemble output generated for others; you receive no exclusivity in ideas, patterns or boilerplate common across projects.
You are responsible for ensuring that your use of generated code (including any third-party or open-source components it incorporates) complies with applicable licences and law.
6. Shared infrastructure (Free, Core and Pay-as-you-go plans)
On the Free, Core and Pay-as-you-go plans, builds, sprint sandboxes and previews run on shared, multi-tenant infrastructure. Workloads are separated using technical isolation measures — including container isolation, per-workload resource limits and network hardening — and we take commercially reasonable steps to keep tenants separated and the platform secure.
These plans are provided without any service-level agreement: we do not guarantee uptime, availability, build capacity or turnaround times, and previews and sandboxes may be paused, rescheduled or reclaimed to manage shared capacity.
As part of the allocation of risk reflected in the pricing of these plans, and to the maximum extent permitted by law, our total liability for unauthorised access to, or disclosure of, User Content (including source code) arising from a compromise of shared infrastructure is limited to the fees you paid to us in the twelve (12) months before the event giving rise to the claim. Nothing in this section limits liability that cannot be limited by law (see Section 10). If your projects require stronger isolation or contractual availability commitments, choose a dedicated-infrastructure plan (Section 7).
7. Dedicated infrastructure (Pro and Enterprise)
The Pro plan runs your sprint sandboxes, builds and previews on dedicated per-account hardware, and includes a service-level agreement with a 99.5% monthly uptime target for previews and builds, with the detailed commitments, exclusions and remedies as described in your plan. Enterprise plans (available on request) also run on dedicated infrastructure, with custom service levels agreed in your order form or enterprise agreement. Where an SLA applies, service credits as described in your plan are your sole and exclusive remedy for failure to meet it.
8. Third-party services
The Service depends on third-party providers — cloud hosting, payment processors and machine-learning model providers — and on destinations you connect (such as your own domains or hosting accounts). We are not responsible for third-party services we do not control, and your use of them may be subject to their own terms.
9. Disclaimer of warranties
Except as expressly set out in these Terms (including any SLA that applies to your plan), the Service is provided "as is" and "as available". To the maximum extent permitted by law, we exclude all implied warranties, conditions and other terms, including any implied terms of satisfactory quality, fitness for a particular purpose and non-infringement. We do not warrant that the Service will be uninterrupted, error-free or secure, or that generated applications will meet your requirements. Nothing in these Terms affects any statutory rights you have as a consumer that cannot be excluded by agreement.
10. Limitation of liability
Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under the law of England and Wales.
Subject to the above: (a) we are not liable for loss of profits, revenue, business, goodwill or anticipated savings, or for indirect or consequential loss; (b) we are not liable for loss or corruption of data to the extent you could have avoided it by exporting your repository or maintaining copies; and (c) our total aggregate liability arising out of or in connection with the Service in any twelve-month period is limited to the greater of the fees you paid to us in that period and £100. Section 6 sets out the specific limit that applies to shared-infrastructure compromise on the Free, Core and Pay-as-you-go plans.
11. Suspension and termination
You may stop using the Service and close your account at any time. We may suspend or terminate your access if you materially breach these Terms, if required by law, or if we reasonably believe your use poses a security or legal risk; where practicable we will give you notice and an opportunity to export your projects. We may also discontinue or materially change parts of the Service on reasonable notice. On termination your right to use the Service ends; sections which by their nature should survive (including Sections 5, 6, 9, 10 and 13) survive.
12. Changes to these Terms
We may update these Terms from time to time. For material changes we will give reasonable advance notice (for example by email or in-product). Continued use of the Service after a change takes effect constitutes acceptance of the updated Terms.
13. Governing law and jurisdiction
These Terms, and any dispute or claim arising out of or in connection with them or the Service, are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that if you are a consumer you may also be entitled to bring proceedings in, and rely on the mandatory consumer protections of, the country where you live.
