By purchasing or using AI App Factory ("the Product"), you agree to be bound by these Terms of Service. The Product is provided by Product Engineer ("we", "us", or "our"). If you do not agree to these terms, please do not purchase or use the Product.
AI App Factory is a digital product consisting of software boilerplate code, templates, documentation, and related materials designed to help developers build and launch mobile applications. The Product is delivered digitally — upon purchase, a private repository is generated in your own GitHub account from our prebuilt template.
Upon purchase, we grant you a non-exclusive, non-transferable license to use the Product subject to the following terms based on your purchased tier:
The Product, including all source code, documentation, and related materials, is the intellectual property of Product Engineer. Your purchase grants you a usage license, not ownership of the intellectual property. You own the applications you build using the Product.
The Product is sold as a one-time purchase. Payments are processed through Lemon Squeezy (for USD transactions) and PortOne (for KRW transactions). All prices are displayed at the time of purchase and are subject to change without prior notice for future purchases. Your purchase price is locked at the time of transaction.
Upon successful payment, you connect your GitHub account and generate a private repository in your own account from our prebuilt template. The generated repository is yours to own and manage. Delivery is automated and typically occurs within minutes. If you experience any issues with delivery, please contact us at support@productengineer.info.
You may not:
Since the repository is generated in your own GitHub account, you retain full ownership and access permanently. Product updates (bug fixes, new features, and improvements) are delivered to your repository for 1 year from the date of purchase. After the 1-year update period, your repository and all previously delivered materials remain yours, but no further updates are guaranteed. Support is provided via email at support@productengineer.info. We aim to respond to support inquiries within 2 business days.
Pro and Team Tier Update Access: Pro and Team tier purchases include read-only access to the source template repository via GitHub organization membership for receiving updates. This access is personal and non-transferable. You may use this access solely to pull updates into your own licensed repository. We reserve the right to revoke template repository access if these terms are violated or upon license termination.
The Product is provided "as is" without warranties of any kind, either express or implied. We do not guarantee that the Product will meet your specific requirements or that it will be error-free. In no event shall Product Engineer be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the Product. Our total liability shall not exceed the amount you paid for the Product.
We reserve the right to revoke your license if you materially violate these Terms of Service. We will provide written notice of the alleged violation and allow 14 days to cure the breach before termination takes effect. Upon termination, you must cease all use of the Product and delete any copies in your possession. Refund eligibility upon termination is governed by our Refund Policy.
We reserve the right to modify these terms at any time. Changes will be posted on this page with an updated "Last updated" date. Your continued use of the Product after changes constitutes acceptance of the modified terms.
These terms shall be governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict of law provisions. However, if you are a consumer residing in the United States, nothing in these terms limits your rights under applicable U.S. federal or state consumer protection laws, and you may bring claims in your local jurisdiction as permitted by applicable law.
If any provision of these Terms is held to be unenforceable or invalid by a court of competent jurisdiction, the remaining provisions will remain in full force and effect. The unenforceable provision will be modified to the minimum extent necessary to make it enforceable while preserving its original intent.
