These Terms of Use ("Terms") are a binding agreement between you ("you", "User") and Qira Labs ("we", "us"), the developer of the NEC Electrical Calculator mobile application ("the App"). By downloading, installing, accepting the in-app disclaimer, or using the App, you agree to these Terms. If you do not agree, do not use the App.
Read this first
The App is a calculation aid for qualified personnel. It is not an engineering service, not a substitute for professional judgment, and not a code-compliance authority. Every result must be independently verified by a licensed electrical professional and by the authority having jurisdiction (AHJ) before it is relied upon for any design, installation, purchase, inspection or safety decision. You are solely responsible for any decision you make and for any work you perform.
We grant you a limited, personal, non-exclusive, non-transferable, revocable license to use the App on devices you own or control, for your own professional or personal purposes, in accordance with these Terms and the Google Play Terms of Service. You may not reverse engineer, decompile, redistribute, resell, sublicense or create derivative works from the App, except where such restriction is prohibited by law.
The App is intended for use by qualified persons as that term is understood in the electrical trades — licensed electricians, electrical contractors, engineers, inspectors, apprentices under supervision, and students. It is intended as a means of speeding up routine calculations that the user is already competent to perform and to verify independently.
The App is not intended for, and must not be used as, the sole basis for any electrical installation, modification, repair or energization by an unqualified person. Electrical work performed incorrectly can cause fire, property destruction, serious injury and death.
The App does not provide engineering, design, legal, inspection or code-compliance advice, and no professional relationship of any kind is created between you and us by your use of it. No output of the App — including the PDF Calculation Report — constitutes a sealed, stamped, signed or certified engineering document, and none may be represented as such. The PDF Calculation Report is a summary of the inputs you entered and the arithmetic the App performed; it carries no professional endorsement.
Calculations reference the National Electrical Code (NEC 2023 / NFPA 70). Adopted code editions, amendments and local requirements vary by jurisdiction and change over time. Your jurisdiction may have adopted a different edition, or may have amended the one referenced here. It is your responsibility to confirm which requirements apply to your work and to verify results against the actual code text adopted where the work is performed.
The App may contain errors, omissions, outdated values or defects. We make no representation that the App is free of them. Tables, factors and rules implemented in the App are derived values used for computation and are not a reproduction of, or a substitute for, the code text itself.
NEC® and NFPA 70® are registered trademarks of the National Fire Protection Association (NFPA). The App is an independent product. It is not affiliated with, authorized by, endorsed by, sponsored by, reviewed by, or connected to the NFPA in any way. References to the code are nominative, made solely to identify the standard the calculations are based on.
The App is provided "as is" and "as available", with all faults and without warranty of any kind. To the maximum extent permitted by applicable law, we expressly disclaim all warranties, whether express, implied, statutory or otherwise, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, accuracy, reliability, quiet enjoyment and non-infringement.
We do not warrant that the App will be accurate, complete, error-free, uninterrupted, secure, current with any code edition, or compliant with the requirements of any jurisdiction, nor that any result it produces will be correct or suitable for any purpose. No advice or information, whether oral or written, obtained from us or through the App, creates any warranty not expressly stated in these Terms.
To the maximum extent permitted by applicable law, in no event shall Qira Labs, its owner, developers, contributors, suppliers or licensors be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, business, goodwill, contracts, or for any personal injury, death, fire, property damage, code violation, failed inspection, rework, delay, fine, or business interruption, arising out of or in connection with your use of, or inability to use, the App — whether based in contract, tort (including negligence), strict liability, product liability, statute or any other legal theory, and whether or not we have been advised of the possibility of such damages.
To the maximum extent permitted by applicable law, our total aggregate liability for all claims arising out of or relating to the App or these Terms shall not exceed the greater of (a) the amount you actually paid for the App in the twelve (12) months preceding the event giving rise to the claim, or (b) five U.S. dollars (US$5.00).
Some jurisdictions do not allow the exclusion of certain warranties or the limitation or exclusion of liability for certain damages. In those jurisdictions, the exclusions and limitations above apply to the fullest extent permitted by that jurisdiction's law, and nothing in these Terms limits liability that cannot lawfully be limited.
You acknowledge that electrical work is inherently hazardous, that the consequences of an incorrect calculation can include fire, electrocution, serious injury and death, and that professional verification is the control that prevents those outcomes. You knowingly and voluntarily assume all risk arising from your use of the App and from any reliance you place on its output.
You agree to defend, indemnify and hold harmless Qira Labs, its owner and its developers from and against any claims, demands, actions, damages, losses, liabilities, judgments, settlements, costs and expenses (including reasonable attorneys' fees) arising out of or relating to (a) your use or misuse of the App, (b) any work, design, installation, inspection or decision you based in whole or in part on the App, (c) your violation of these Terms, or (d) your violation of any law or of the rights of any third party.
The Pro Version is a one-time purchase processed entirely by Google Play Billing. We never receive or store your payment details. Refunds are governed by Google Play's refund policy and are handled by Google, not by us. Advertising in the free version is served by Google AdMob and is subject to Google's terms.
Our handling of information is described in the Privacy Policy, which is incorporated into these Terms by reference.
We may modify these Terms at any time. Material changes will be reflected by a new version number and effective date on this page, and continued use of the App after a change constitutes acceptance of the revised Terms. We may also modify, suspend or discontinue the App, in whole or in part, at any time.
These Terms are governed by the laws of the Federative Republic of Brazil, where the developer is established, without regard to conflict-of-law principles. Nothing in this section deprives a consumer of the protection afforded by mandatory provisions of the law of their country of residence.
If any provision of these Terms is held unenforceable, that provision shall be limited or severed to the minimum extent necessary, and the remaining provisions shall remain in full force and effect. Our failure to enforce any provision is not a waiver of it. These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the App.
