Terms of Service

These Terms of Service ("Agreement") constitute a legally binding contract between you ("User," "you," or "your") and My Engineering Project LLC, a Florida limited liability company ("Company," "we," "us," or "our"), governing your access to and use of the selectNsolve™ Google Sheets add-on software suite, including the Basic (free), Pro, and Classroom tiers (collectively, the "Software" or "Service").

By installing, enabling, accessing, or using the Software in any capacity, you represent that you have read, understood, and agree to be bound by this Agreement and our Privacy Policy, incorporated herein by reference.

selectNsolve™ is a computational tool that assists users in setting up and solving mathematical equations, unit conversions, and related numerical calculations within Google Sheets. The Software is provided as a productivity aid ONLY. It is NOT a licensed professional engineering service, professional design tool, or substitute for independent professional judgment.

Features vary by tier: Basic (free) provides core equation-solving functionality; Pro adds multi-variable solvers, unit management, and advanced constraint handling; Classroom adds enhanced capacity and educational features.

THE SOFTWARE DOES NOT CONSTITUTE AND SHALL NOT BE CONSTRUED AS PROFESSIONAL ENGINEERING ADVICE, STRUCTURAL ENGINEERING GUIDANCE, MECHANICAL ENGINEERING DESIGN, ELECTRICAL ENGINEERING DESIGN, PLUMBING OR HVAC ENGINEERING DESIGN, FIRE PROTECTION ENGINEERING DESIGN, ARCHITECTURAL DESIGN, LEGAL ADVICE, FINANCIAL ADVICE, MEDICAL ADVICE, OR ANY OTHER LICENSED PROFESSIONAL SERVICE.

All outputs generated by the Software, regardless of tier, are raw computational results based solely on the mathematical equations, inputs, and constraints provided by the User. The accuracy, completeness, and appropriateness of any output depend entirely on the correctness of the User's inputs, equations, and constraints.

Users who are licensed professionals are solely responsible for independently verifying all Software outputs and exercising their own professional judgment before incorporating any result into any professional work product, design document, engineering drawing, permit submission, or advice given to any third party.

Users who are not licensed professionals are solely responsible for consulting appropriate licensed professionals before relying on any Software output for any purpose involving safety, structural integrity, life safety systems, code compliance, or any regulated activity.

THE SOFTWARE AND ALL OUTPUTS THEREFROM ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, MY ENGINEERING PROJECT LLC EXPRESSLY DISCLAIMS ALL WARRANTIES INCLUDING, WITHOUT LIMITATION:

• Any implied warranty of merchantability, fitness for a particular purpose, or non-infringement;
• Any warranty that the Software will be uninterrupted, error-free, or free of bugs, viruses, or harmful components;
• Any warranty that computational outputs will be accurate, complete, current, or suitable for any purpose;
• Any warranty that the Software conforms to any engineering standard, building code, or regulatory requirement;
• Any warranty arising from course of dealing, course of performance, or usage of trade.

NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY THE COMPANY OR ANY OF ITS REPRESENTATIVES SHALL CREATE A WARRANTY. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU IN THEIR ENTIRETY, BUT SHALL APPLY TO THE MAXIMUM EXTENT PERMITTED BY LAW.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL MY ENGINEERING PROJECT LLC, ITS OWNERS, MEMBERS, OFFICERS, EMPLOYEES, CONTRACTORS, AGENTS, LICENSORS, OR SUCCESSORS BE LIABLE FOR ANY:

• Direct, indirect, incidental, special, consequential, exemplary, or punitive damages;
• Damages for loss of profits, revenue, data, goodwill, or business opportunities;
• Damages arising from personal injury, property damage, or loss of life resulting from reliance on Software outputs;
• Damages arising from errors, omissions, inaccuracies, or miscalculations in any Software output, regardless of tier;
• Damages arising from the User's failure to independently verify Software outputs;
• Damages arising from use of the Software in connection with any professional engineering, design, architectural, construction, or safety-critical activity;
• Damages arising from third-party claims against the User based on the User's reliance on Software outputs;

WHETHER BASED ON WARRANTY, CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER LEGAL OR EQUITABLE THEORY, EVEN IF THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ALL CLAIMS ARISING FROM OR RELATING TO THIS AGREEMENT OR THE SOFTWARE SHALL NOT EXCEED THE GREATER OF: (A) THE TOTAL AMOUNT PAID BY YOU TO THE COMPANY IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE CLAIM; OR (B) TEN UNITED STATES DOLLARS ($10.00). FOR USERS OF THE FREE (BASIC) TIER, THE COMPANY'S TOTAL MAXIMUM LIABILITY SHALL BE ZERO DOLLARS ($0.00).

You agree to defend, indemnify, hold harmless, and release My Engineering Project LLC, its members, officers, contractors, agents, and successors (collectively, "Indemnified Parties") from and against any and all claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to:

• Your use of the Software or any output therefrom;
• Your reliance on any Software output without independent professional verification;
• Your incorporation of any Software output into any professional work product, design, submission, or advice;
• Any claim by a third party (including your clients, employers, regulators, or government authorities) arising from your use of Software outputs;
• Your violation of this Agreement, any applicable law, or any third-party rights;
• Any errors, omissions, or inaccuracies in the inputs, equations, or constraints you provided to the Software.

This indemnification obligation survives termination of this Agreement and your cessation of use of the Software.

By using the Software, you expressly acknowledge and agree that:

• You are solely responsible for verifying the accuracy of all inputs, equations, constraints, and assumptions you provide to the Software;
• You are solely responsible for verifying all computational outputs before use in any application;
• No Software output replaces the judgment of a licensed professional engineer or other licensed professional;
• You will not use Software outputs as the sole basis for any design, construction, or decision affecting public safety, structural integrity, life safety systems, or regulated activities without independent professional review;
• The Levenberg-Marquardt and other numerical solvers used by the Software are iterative approximation algorithms that may produce locally optimal but globally incorrect solutions, and may fail to converge under certain conditions;
• Results may vary based on initial conditions, convergence tolerances, and the mathematical properties of the system of equations provided.
