END USER LICENSE AGREEMENT — CIRCUITMCP FOR ALTIUM IMPORTANT: READ THIS AGREEMENT BEFORE INSTALLING THE SOFTWARE. BY INSTALLING OR USING CIRCUITMCP FOR ALTIUM ("the Software") YOU AGREE TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT AGREE, DO NOT INSTALL OR USE THE SOFTWARE. 1. LICENSE GRANT Subject to your payment of the applicable fees and compliance with this Agreement, Holley Brothers Design ("we", "us") grants you a non-exclusive, non-transferable, revocable license to install and use the Software. Your license key entitles you to a stated number of CONCURRENT SEATS. A seat is consumed while a machine holds an active lease and is returned when that machine shuts the Software down cleanly, releases its seat, or its lease expires. You may install the Software on any number of machines provided the number running it concurrently does not exceed your seat count. 2. LICENSE ENFORCEMENT AND OFFLINE USE The Software contacts our license server to obtain and renew a lease. A machine may operate without network access for the offline period stated in its lease. When that period elapses, the Software stops performing design operations until it can reach the license server again. This is a designed behaviour of the licensing model, not a defect. The Software transmits, for licensing purposes only: your license key, a one-way hash identifying the machine, its hostname, and its operating-system version. It does not transmit your designs, schematics, board files, or any other content. 3. RESTRICTIONS You may not: (a) circumvent, disable, or tamper with the licensing mechanism; (b) reverse engineer, decompile, or disassemble the Software except to the extent that applicable law expressly permits despite this limitation; (c) rent, lease, lend, resell, sublicense, or provide the Software as a service to third parties; (d) remove or alter any proprietary notices; or (e) share your license key outside your organization. 4. OWNERSHIP The Software is licensed, not sold. We retain all right, title, and interest in the Software, including all intellectual property rights. You retain all rights in the designs and files you create with it. We claim no ownership of, and no license to, your design data. 5. THIRD-PARTY SOFTWARE The Software interoperates with Altium Designer, which is not provided under this Agreement. You are responsible for holding a valid Altium Designer license. We are not affiliated with, endorsed by, or sponsored by Altium Limited. "Altium" and "Altium Designer" are trademarks of Altium Limited and are used here only to identify the software with which this product interoperates. The Software includes open-source components; their licenses are in the THIRD-PARTY-NOTICES file in the installation directory and, where those licenses conflict with this Agreement, they govern their components. 6. SUPPORT AND UPDATES Support and updates are provided as described in your purchase terms. We may change the Software's features in any release. 7. DISCLAIMER OF WARRANTY THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. YOU ARE RESPONSIBLE FOR VERIFYING ALL DESIGN OUTPUT. The Software automates operations on electronic design files, including operations that modify them irreversibly. It may be driven by AI systems that can make mistakes. Review every design and every manufacturing output before committing it to fabrication, assembly, or production, and keep backups of your design data. 8. LIMITATION OF LIABILITY TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR DESIGN WORK, OR THE COST OF SCRAPPED OR REWORKED HARDWARE, ARISING OUT OF OR RELATED TO THE SOFTWARE. OUR TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE TWELVE MONTHS PRECEDING THE CLAIM. Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages, so some of the above may not apply to you. 9. TERM AND TERMINATION This Agreement runs until terminated. It terminates automatically if you breach it. We may also revoke a license key for non-payment or breach; the Software will then stop operating at each machine's next lease renewal or at the end of its current offline period. On termination you must stop using and uninstall the Software. 10. GOVERNING LAW This Agreement is governed by the laws of the State of Oklahoma, United States of America, without regard to its conflict-of-law rules. 11. ENTIRE AGREEMENT This Agreement is the entire agreement between you and us regarding the Software and supersedes all prior communications. If any provision is held unenforceable, the remainder stays in effect. Contact: Holley Brothers Design (https://holleybrothersdesign.com), support@circuitmcp.net Version 1.0
