Terms of Service

Effective Date: March 30, 2025  |  Last Updated: March 30, 2025

Please read these Terms of Service ("Terms") carefully before using BMI Dashboard (the "Service"), a free online health calculator operated by SPINAI ("we," "us," or "our"). By accessing or using the Service at https://bmi-bodyfat.vercel.app or any associated URL, you agree to be bound by these Terms in their entirety. If you do not agree with any part of these Terms, you must discontinue use of the Service immediately.

1. Acceptance of Terms

By accessing, browsing, or using BMI Dashboard in any manner, you acknowledge that you have read, understood, and agree to comply with these Terms of Service, as well as our Privacy Policy, which is incorporated into these Terms by reference. Your use of the Service constitutes a binding legal agreement between you and SPINAI. If you are accessing the Service on behalf of an organization, company, or other legal entity, you represent and warrant that you have the authority to bind that entity to these Terms, and the terms "you" and "your" shall refer to that entity.

You confirm that you are at least 13 years of age, or that you have obtained the consent of a parent or legal guardian to use the Service. Users under the age of 13 are not permitted to use BMI Dashboard. We reserve the right to terminate access for any user who we reasonably believe is under the minimum age requirement without parental consent. By continuing to use the Service after any modifications to these Terms, you accept and agree to be bound by the revised Terms.

2. Description of Service

BMI Dashboard is a free, web-based health and fitness tool that provides users with the ability to calculate their Body Mass Index (BMI) and estimate their body fat percentage. The BMI calculation is based on the standard formula endorsed by the World Health Organization (WHO), which divides an individual's weight in kilograms by the square of their height in meters. The body fat percentage estimation uses the US Navy circumference method, which derives an estimate based on gender-specific body circumference measurements including the neck, waist, and (for females) hip measurements.

The Service supports both metric (kilograms and centimeters) and imperial (pounds, feet, and inches) unit systems and provides results along with general health category classifications based on WHO and other recognized standards. BMI Dashboard operates entirely in the user's web browser, meaning all calculations are performed client-side using JavaScript. No health data is transmitted to or stored on our servers. The Service also includes educational content about BMI categories, body fat percentage ranges, and general health and fitness information. All features of the Service are provided free of charge, and no user registration or account creation is required.

3. Use of the Calculator

BMI Dashboard grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for personal, non-commercial, informational purposes. You may use the Service to calculate your own BMI and body fat percentage, to learn about health categories and reference ranges, and to explore the educational content provided on our website. You are welcome to share your personal results with healthcare providers, fitness professionals, or family members for the purpose of health discussions.

You agree not to use the Service in any of the following prohibited ways:

  • Using the Service in any manner that violates applicable local, state, national, or international laws, regulations, or ordinances.
  • Attempting to reverse-engineer, decompile, disassemble, copy, reproduce, or redistribute the Service's source code, algorithms, or design without prior written permission from SPINAI.
  • Using automated tools, bots, scrapers, crawlers, or other software to access, index, or stress-test the Service without express written authorization.
  • Misrepresenting, framing, or presenting results generated by the Service as official medical assessments, diagnoses, or professional health evaluations.
  • Interfering with or disrupting the Service's infrastructure, servers, or networks, including attempting to gain unauthorized access to any systems connected to the Service.
  • Using the Service to collect, harvest, or aggregate data about other users without their explicit consent.
  • Transmitting any viruses, malware, worms, or other malicious code through or in connection with the Service.

4. Medical Disclaimer

BMI Dashboard does not provide medical advice, diagnosis, or treatment. This is the most important section of these Terms, and we urge you to read it carefully. The calculations, results, health category classifications, educational text, and all other content on this website are provided solely for general informational and educational purposes. They are not intended to serve as a substitute for professional medical advice, clinical diagnosis, or medical treatment of any kind.

Body Mass Index (BMI) and body fat percentage are population-level screening tools and statistical estimates, not clinical diagnostic instruments. These metrics have well-documented limitations that are important to understand. BMI does not distinguish between muscle mass and fat mass, which means that muscular individuals may be classified as "overweight" or "obese" despite having a healthy body composition. BMI may also be less accurate for certain populations, including but not limited to: professional and amateur athletes, elderly individuals experiencing age-related muscle loss (sarcopenia), pregnant or breastfeeding women, growing children and adolescents, and individuals of certain ethnic backgrounds for whom standard BMI thresholds may not be appropriate.

The US Navy circumference method for estimating body fat percentage, while validated in research studies, relies on external body circumference measurements that are inherently subject to measurement error. Factors such as tape placement, posture, breathing, hydration level, recent meals, and time of day can all influence the accuracy of circumference measurements and, consequently, the body fat percentage estimate. Furthermore, neither BMI nor the US Navy method accounts for fat distribution within the body (for example, the difference between visceral fat surrounding internal organs and subcutaneous fat beneath the skin), which is an important factor in assessing metabolic health risk.

Always consult a qualified healthcare professional — such as a licensed physician, registered dietitian, certified clinical nutritionist, or certified fitness professional — before making any decisions or changes regarding your diet, exercise regimen, weight management plan, or overall health management strategy. Never disregard professional medical advice or delay seeking medical consultation because of something you have read on or calculated through this website. If you are experiencing a medical emergency, contact your local emergency services (such as 911 in the United States) immediately. BMI Dashboard is not designed for and should not be used in emergency medical situations.

5. User Responsibilities

As a user of BMI Dashboard, you acknowledge and agree that you bear sole responsibility for the accuracy of the measurements and data you enter into our calculators. The quality and reliability of the results produced by our tools depend directly on the accuracy of the input values you provide. We recommend using properly calibrated measurement tools (such as a digital scale for weight and a rigid stadiometer or wall-mounted height chart for height) and following established measurement protocols for circumference measurements (such as measuring the waist at the narrowest point of the torso, at the level of the navel, while standing and breathing normally).

You agree not to share, distribute, or present calculator results as professional medical assessments, clinical diagnoses, or certified health evaluations. Results from BMI Dashboard are personal reference tools and should be interpreted within the context of your individual health situation, ideally with the guidance of a qualified healthcare provider. You acknowledge that health and body composition are influenced by numerous factors beyond what BMI and body fat percentage can capture, including genetics, medical history, medications, mental health, sleep quality, stress levels, and overall lifestyle habits.

6. Intellectual Property

All content on BMI Dashboard — including but not limited to text, graphics, user interface design, visual layout, JavaScript code, CSS stylesheets, SVG assets, icons, logos, and any other creative or functional elements — is the exclusive intellectual property of SPINAI or its licensors and is protected by applicable copyright, trademark, trade dress, and other intellectual property laws in the United States and internationally.

You may not remove, alter, obscure, or deface any copyright notices, trademark symbols, or other proprietary rights notices affixed to or contained within the Service. Any unauthorized use of our intellectual property may result in legal action and termination of your access to the Service.

7. Third-Party Links and Services

BMI Dashboard may contain advertisements provided by third-party advertising networks, including Google AdSense, as well as hyperlinks to external websites, resources, or services that are not owned, operated, or controlled by SPINAI. These third-party links and advertisements are provided for your convenience and informational purposes only. We do not endorse, sponsor, recommend, or assume any responsibility for the content, products, services, privacy practices, or policies of any third-party websites or services.

When you click on a third-party link or interact with a third-party advertisement, you may be directed to a website or platform that is governed by its own terms of service and privacy policy, which may differ significantly from ours. We strongly encourage you to review the terms and privacy policies of any third-party site before providing any personal information or engaging in any transactions. SPINAI shall not be liable for any loss, damage, or harm of any kind arising from your interaction with third-party content, advertisements, or websites accessed through our Service.

8. Disclaimer of Warranties

THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, SPINAI EXPRESSLY DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. We do not warrant that the Service will be uninterrupted, error-free, secure, or free of viruses or other harmful components. We do not guarantee the accuracy, completeness, reliability, or timeliness of any calculations, results, health information, or other content provided through the Service.

No advice or information, whether oral or written, obtained from SPINAI, the Service, or through any related communication shall create any warranty not expressly stated in these Terms. You acknowledge that you use the Service at your own risk and that you are solely responsible for any decisions you make based on the information provided by the Service.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SPINAI AND ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, SUPPLIERS, AND LICENSORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF PROFITS, DATA, GOODWILL, USE, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF OR INABILITY TO USE THE SERVICE. This limitation applies regardless of whether such damages are based on warranty, contract, tort (including negligence), strict liability, or any other legal theory, and regardless of whether SPINAI has been advised of the possibility of such damages.

Without limiting the foregoing, SPINAI shall not be liable for any harm, injury, adverse health outcome, or medical complication that results, directly or indirectly, from your reliance on calculator results, health category classifications, or any other information provided by the Service. You expressly acknowledge and agree that BMI Dashboard is not a medical device and that its results should never be used as the sole basis for health-related decisions. Some jurisdictions do not allow the exclusion or limitation of certain types of damages or liability, so the above limitations may not apply to you in full. In such jurisdictions, SPINAI's liability shall be limited to the maximum extent permitted by applicable law.

10. Indemnification

You agree to indemnify, defend, and hold harmless SPINAI and its affiliates, officers, directors, employees, agents, contractors, and licensors from and against any and all claims, demands, losses, liabilities, damages, costs, and expenses (including reasonable attorneys' fees and legal costs) arising out of or related to: (a) your use of or access to the Service; (b) your violation of these Terms or any applicable law, regulation, or third-party right; (c) any content or data you provide through the Service; (d) any harm or damage caused to a third party as a result of your use of the Service or your reliance on its results; or (e) your negligence or willful misconduct. This indemnification obligation shall survive the termination of these Terms and your cessation of use of the Service.

11. Governing Law

These Terms of Service shall be governed by and construed in accordance with the laws of the United States and the State of California, without regard to its conflict of law principles. Any legal action, suit, or proceeding arising out of or related to these Terms or the Service shall be instituted exclusively in the federal or state courts located in California, and you consent to the personal jurisdiction and venue of such courts. You agree to waive any objection to the exercise of jurisdiction over you by such courts and to the venue of such courts. Notwithstanding the foregoing, SPINAI may seek injunctive or other equitable relief in any court of competent jurisdiction to protect its intellectual property rights.

12. Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such invalidity, illegality, or unenforceability shall not affect the remaining provisions of these Terms, which shall continue in full force and effect. The invalid or unenforceable provision shall be modified to the minimum extent necessary to make it valid, legal, and enforceable while preserving the original intent of the parties. If such modification is not possible, the offending provision shall be deemed severed from these Terms, and the remaining provisions shall be interpreted as if the severed provision had never been included.
