If you do not agree to all the terms and conditions of this agreement, then you may not access the Website or use any services. If these terms and conditions are considered an offer by CircuitLab, acceptance is expressly limited to these terms. The Website is available only to individuals who are at least 13 years old.
Your CircuitLab Account. If you create an account on the Website, you are responsible for maintaining the security of your account, and you are fully responsible for all activities that occur under the account and any other actions taken in connection with it. CircuitLab may change or remove any content or description or data that it considers inappropriate or unlawful, or otherwise likely to cause CircuitLab liability. You must immediately notify CircuitLab of any unauthorized uses of your account or any other breaches of security. CircuitLab will not be liable for any acts or omissions by You, including any damages of any kind incurred as a result of such acts or omissions.
Your Content. If you publish any content or data on the Website, or otherwise make (or allow any third party to make) material available by means of the Website (any such material, including resulting calculations and simulations, collectively "Content"), You are entirely responsible for the content of, and any harm resulting from, that Content. That is the case regardless of whether the Content in question constitutes text, graphics, audio, video, computer software, circuit schematics, or simulations. We do not claim ownership of your Content, but this Agreement does grant us the limited rights necessary to run our service.
By making Content available, you represent and warrant that:
By submitting Content to CircuitLab for inclusion on the Website, you grant CircuitLab a world-wide, royalty-free, irrevocable, and non-exclusive license to reproduce, modify, adapt and publish the Content for the purpose of displaying, distributing, and making it available for use by our tools, and for any associated incidental copying of said Content. You grant CircuitLab permission to collect and publish analytics and metadata about your Content and your use of the CircuitLab software. Additionally, by submitting Content to be made available for public distribution (for example, by marking a schematic as available for public distribution), you grant CircuitLab a world-wide, royalty-free, irrevocable, and non-exclusive license to reproduce, modify, adapt, and publish the Content for any marketing or promotional purposes at the sole discretion of CircuitLab. You understand and acknowledge that submitting Content to the Website intended for public distribution may additionally grant limited rights to your Content to third parties under the doctrine of fair use. If you delete Content, CircuitLab will use reasonable efforts to remove it from the Website, but you acknowledge that caching or references to the Content may not be made immediately unavailable.
Without limiting any of those representations or warranties, CircuitLab has the right (though not the obligation) to, in CircuitLab's sole discretion (i) refuse or remove any content that, in CircuitLab's reasonable opinion, violates any CircuitLab policy or is in any way harmful or objectionable, or (ii) terminate or deny access to and use of the Website to any individual or entity for any reason, in CircuitLab's sole discretion. CircuitLab will have no obligation to provide a refund of any amounts previously paid.
Responsibility of Website Visitors. CircuitLab has not reviewed, and cannot review, all of the material, including computer software, posted to the Website, and cannot therefore be responsible for that material's content, use or effects. By operating the Website, CircuitLab does not represent or imply that it endorses the material there posted, or that it believes such material to be accurate, useful or non-harmful. You are responsible for taking precautions as necessary to protect yourself and your computer systems from viruses, worms, Trojan horses, and other harmful or destructive content. The Website may contain content that is offensive, indecent, or otherwise objectionable, as well as content containing technical inaccuracies, typographical mistakes, and other errors. The Website may also contain material that violates the privacy or publicity rights, or infringes the intellectual property and other proprietary rights, of third parties, or the downloading, copying or use of which is subject to additional terms and conditions, stated or unstated. CircuitLab disclaims any responsibility for any harm resulting from the use by visitors of the Website, or from any downloading by those visitors of content there posted.

Changes. CircuitLab reserves the right, at its sole discretion, to modify or replace any part of this agreement. It is your responsibility to check this agreement periodically for changes. Your continued use of or access to the website following the posting of any changes to this agreement constitutes acceptance of those changes.

Such new features and/or services shall be subject to the terms and conditions of this agreement.
Termination. CircuitLab may terminate your access to all or any part of the Website at any time, with or without cause, with or without notice, effective immediately. All provisions of this agreement which by their nature should survive termination shall survive termination, including, without limitation, ownership provisions, warranty disclaimers, indemnity and limitations of liability.
Modification of Terms Surcharge. If you request changes to this Terms of Service or any other agreement, for any reason, an additional "Modifications of Terms Surcharge" will apply. This surcharge is an additional 200% of the value of the base contract, or $1,200, whichever is greater. This surcharge will be added to your quote and invoice. Payment of the surcharge is required to activate your service. For recurring contracts, the surcharge will apply to all renewals.
