Agreement to Terms

Welcome to Diet Planner, accessible from dietplanner.io (the “Website,” “we,” “us,” or “our”). These Terms and Conditions (“Terms”) govern your access to and use of the Website, including every calculator, tool, and piece of content available on it — from our Health Calculators (BMI, Calorie, Macro, DRI, A1C, Iron Intake, Vitamin D, Electrolyte, Water Intake, Intermittent Fasting, and Ultra Processed Food) to our Fitness Calculators (Strength Level, FFMI, DOTS Score, Body Fat Percentage, Body Type, Metabolic Age, and the rest of our fitness toolkit) and our general-purpose utility tools (Scientific Calculator, CGPA Calculator, Age Calculator, Password Generator, Stylish Name Generator) collectively, the “Service.”

Diet Planner is operated by an individual, not a registered company, consistent with how we describe ourselves in our Privacy Policy.

By accessing or using the Service, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated into these Terms by reference. If you do not agree, please do not use the Service.

We may update these Terms at any time. Changes take effect immediately upon posting, and the “Last Updated” date above will be revised. Continuing to use the Service after changes are posted means you accept the revised Terms.

Who Can Use This Service

Diet Planner is not intended for children under the age of 13, and our health and fitness calculators are designed for users aged 15 and older. If you are between 13 and 17, please use the Service only with the involvement of a parent or guardian, particularly for any calculator producing health, nutrition, or training-related results. By using the Service, you confirm that you meet this age guidance.

What This Service Is — and Is Not

Diet Planner provides free, browser-based calculators and educational content covering nutrition, body composition, and fitness planning, alongside a small set of unrelated general-purpose utilities (scientific calculator, age calculator, password generator, and similar tools).

Our health and fitness calculators are built on established, named formulas and public health guidelines, including but not limited to the Mifflin-St Jeor equation and Harris-Benedict formula (BMR/TDEE), World Health Organization (WHO) BMI classifications, the U.S. Navy circumference method (body fat percentage), the Epley formula (one-rep max estimation), ADA-referenced formulas (A1C conversion), and published strength-scoring systems such as Wilks and DOTS. We reference these sources so you know exactly what’s behind each result — but referencing a formula does not mean the output is a clinical measurement.

Our general-purpose utility tools (Scientific Calculator, CGPA Calculator, Age Calculator, Password Generator, Stylish Name Generator) are provided as a convenience and are not health-related; use of these tools is governed by these Terms but not by the medical disclaimers in Section 4 below.

Not Medical, Nutritional, or Professional Advice

This is the most important section of these Terms — please read it carefully.

Nothing on Diet Planner — no calculator result, article, or piece of content — constitutes medical, nutritional, dietary, or fitness advice, and using the Service does not create a doctor-patient, dietitian-client, or trainer-client relationship of any kind.

Do not use any result from this Service as a substitute for professional judgment from a physician, registered dietitian, or certified fitness professional. Always consult a qualified healthcare provider before making decisions about your diet, exercise routine, supplementation, or any existing medical condition — and before acting on any calculator result, particularly if you are pregnant, nursing, managing a diagnosed health condition, have a history of disordered eating, or are new to structured training.

If you believe you may have a medical emergency, contact your doctor or emergency services immediately — do not rely on this Service.

Accuracy and Limitations of Our Calculators

We build every calculator on validated, published formulas and reputable public health sources (WHO, ADA, CDC, and peer-reviewed exercise science research, as referenced on individual calculator pages and our About Us page). That said:

  • Results are estimates, not diagnoses. Formulas like Mifflin-St Jeor or the Navy body fat method are population-derived approximations — individual results vary with genetics, hormonal health, hydration, measurement technique, and other factors no formula can fully account for.
  • Accuracy depends on your inputs. Since every calculation happens locally in your browser using the numbers you provide, an inaccurate self-reported measurement (weight, waist circumference, lift weight, etc.) will directly affect your result.
  • No calculator on this Service is a substitute for clinical testing — such as a DEXA scan, blood panel, or in-person fitness assessment — where higher precision is genuinely needed.

How the Service Works — No Sign-Up, No Data Sent to Us

Every calculator on Diet Planner runs entirely in your browser. Your inputs — age, weight, height, gender, measurements, or any other figure you enter — are processed locally on your device and are never transmitted to our servers, stored in a database, or shared with any third party. Some tools may use your browser’s local storage to remember preferences on your own device; this data never leaves your device and can be cleared at any time through your browser settings.

Full detail on data handling, including our use of Google Analytics for anonymized usage statistics, is available in our Privacy Policy, which forms part of these Terms.

Acceptable Use

By using the Service, you agree not to:

  • misrepresent calculator results as a diagnosis, clinical assessment, or professional recommendation to others (including clients, if you’re a fitness or health professional using our tools as a reference);
  • use automated tools (bots, scrapers, or similar) to access the Service at a volume beyond normal human use;
  • attempt to interfere with, disrupt, reverse-engineer, or gain unauthorized access to the Service or its underlying code;
  • reproduce, republish, or redistribute our calculators, formulas as implemented, or written content without our permission;
  • use the Service for any unlawful purpose.

We may restrict or block access for anyone who violates these Terms.

Intellectual Property

The content, calculators, design, source code, and written material on Diet Planner belong to us or our licensors and are protected by applicable copyright and intellectual property law. You’re welcome to link to our tools, cite our content with attribution, and share results for personal, non-commercial use. You may not copy, republish, or build a competing product from our calculators or written content without prior permission.

Third-Party Links and Sources

Where our content cites external research, public health guidelines, or named studies (for example, WHO, ADA, or CDC sources, or peer-reviewed formulas like Epley or Wilks), we do so to be transparent about our methodology — this does not mean we control, endorse, or are responsible for the entirety of that third party’s content. Any links to external websites are provided for reference only, and we’re not responsible for their content or privacy practices.

No Warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF ACCURACY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT GUARANTEE THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY CALCULATOR RESULT WILL BE ACCURATE FOR YOUR INDIVIDUAL CIRCUMSTANCES.

Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, DIET PLANNER AND ITS OPERATOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING FROM YOUR USE OF THE SERVICE, INCLUDING ANY HEALTH, FITNESS, DIETARY, OR TRAINING DECISION MADE IN RELIANCE ON A CALCULATOR RESULT OR ANY CONTENT ON THIS SITE.

BECAUSE THE SERVICE IS PROVIDED FREE OF CHARGE, WITH NO ACCOUNT, SUBSCRIPTION, OR PAYMENT INVOLVED, OUR TOTAL LIABILITY TO YOU FOR ANY CLAIM RELATED TO THE SERVICE IS LIMITED TO ZERO. Some jurisdictions don’t allow certain liability limitations, so parts of this section may not apply to you depending on where you live.

Health and Safety Notice

If you have a pre-existing medical condition, are pregnant or nursing, are under 18, or have any health concern, consult a qualified healthcare professional before acting on any information or result from this Service. Stop any diet, training, or supplementation approach immediately and seek medical attention if you experience pain, dizziness, irregular heartbeat, or any other concerning symptom.

Privacy

Your use of the Service is also governed by our Privacy Policy, which explains in full detail that we collect no personal data directly, process all calculator inputs locally in your browser, and use Google Analytics only for anonymized usage statistics. Please review it.

Changes to the Service

We may add, modify, or remove calculators, tools, or content at any time, and may update or discontinue the Service in whole or in part without prior notice.

Governing Law

These Terms are governed by applicable law, without regard to conflict of law principles, consistent with the governing law provision in our Privacy Policy. [Note: if you’d like a specific jurisdiction named here for stronger enforceability, let us know which country/region you want these Terms tied to — currently left general to match your Privacy Policy’s existing language.]

Severability

If any part of these Terms is found unenforceable, the remaining provisions stay in full effect.
