Privacy Policy

Effective Date: May 19, 2026
Last Updated: May 19, 2026

Welcome to DRI Calculator (“we,” “us,” “our,” or “the website”). Your privacy is important to us, and we are firmly committed to protecting it. This Privacy Policy explains, in clear and transparent language, what information we collect, how we use it, how we safeguard it, and the rights you have over your personal data when you visit and use our free online Dietary Reference Intake (DRI) calculator.

By accessing or using DRI Calculator, you acknowledge that you have read, understood, and agreed to the practices described in this Privacy Policy. If you do not agree with any part of this policy, please discontinue use of the website.

1. About DRI Calculator

DRI Calculator is a free, publicly accessible online tool that calculates personalized estimates of Dietary Reference Intakes, including daily calorie needs, macronutrient targets (protein, carbohydrates, and fats), and recommended vitamin and mineral intakes. These estimates are generated based on general inputs such as age, biological sex, weight, height, and physical activity level.

The calculations provided by our tool are based on publicly available reference data published by the National Academies of Sciences, Engineering, and Medicine (NASEM), formerly known as the Institute of Medicine (IOM). DRI Calculator is an independent educational resource and is not affiliated with, endorsed by, or sponsored by the National Academies or any government agency.

Educational and Informational Purpose Only. DRI Calculator is intended strictly for general educational and informational purposes. The tool does not provide medical advice, diagnosis, or treatment. It is designed for generally healthy individuals and is not a substitute for professional guidance. Always consult a licensed physician, registered dietitian, or qualified healthcare professional before making decisions about your diet, nutrition, or health, particularly if you are pregnant, nursing, a minor, an elderly individual, or living with a medical condition.

2. Information We Collect

We have designed the DRI Calculator with a privacy-first philosophy. We aim to collect as little personal information as reasonably possible. The information involved when you use our website falls into the following categories.

2.1 Health-Related Calculator Inputs

To generate your personalized estimates, the calculator asks you to provide general physical information, which may include:

• Age or age range
• Biological sex
• Body weight
• Height
• Physical activity level
• Optional life-stage indicators (for example, pregnancy or lactation status, where offered)

Important: These inputs are processed in your browser or transiently on our servers for the sole purpose of producing your results during your active session. We do not require you to create an account, log in, or provide your name, email address, or any directly identifying information to use the calculator. The values you enter are not linked to your identity, and we do not build personal health profiles about you.

2.2 Information You Provide Voluntarily

If you contact us directly — for example, by emailing us or submitting a contact form — we will receive the information you choose to share, such as your name, email address, and the contents of your message. We use this information only to respond to your inquiry.

2.3 Automatically Collected Technical Information

Like most websites, when you visit DRI Calculator, certain technical information may be collected automatically by us and by trusted third-party services. This may include:

• IP address (often truncated or anonymized by analytics providers)
• Browser type and version
• Device type and operating system
• Referring to the website or source
• Pages visited, time spent, and general usage patterns
• Approximate geographic location (typically at the country or region level)

This information is aggregated and statistical in nature and is used to understand site performance, improve user experience, and maintain security.

3. How Information Is Collected

We collect information through the following methods:

• Directly from you when you enter values into the calculator or contact us.
• Automatically through your browser and server logs when you access the website.
• Through third-party tools such as analytics and advertising services that use cookies and similar tracking technologies.

Our website uses cookies and similar tracking technologies to support functionality, analytics, and advertising. A full explanation of how we use these technologies, the types of cookies involved, and how you can manage your preferences is provided separately on our dedicated Cookies Policy page. Please review that page for complete details.

4. Whether Health-Related Input Data Is Stored or Processed

We understand that the information you enter into a health and nutrition calculator can feel sensitive, and we treat it with care and transparency.

• The physical inputs you provide (such as age, sex, weight, height, and activity level) are used only to perform the requested calculation and to display your results.
• Wherever technically feasible, these calculations are performed locally in your browser, meaning your inputs may never leave your device.
• We do not sell, rent, or trade your health-related inputs.
• We do not knowingly use your calculator inputs to identify you as an individual, and these inputs are not linked to your name or contact details.
• We do not retain your individual calculator inputs in a personally identifiable profile after your session ends. Any retained data is limited to aggregated, anonymized, or statistical information that cannot reasonably be used to identify you.

Because the calculator does not require registration, the health-related values you enter are treated as anonymous, non-identifying data.

5. How We Use Your Information

We use the information described in this policy for the following legitimate purposes:

• To operate the calculator and generate your personalized DRI estimates.
• To maintain, secure, and improve the performance and reliability of the website.
• To analyze general usage trends and enhance user experience and content quality.
• To display relevant advertising that helps keep DRI Calculator free to use.
• To respond to your questions, feedback, or support requests.
• To detect, prevent, and address technical issues, fraud, or abuse.
• To comply with applicable legal obligations.

We do not use your information for automated decision-making that produces legal or similarly significant effects on you.

6. Legal Bases for Processing (GDPR)

If you are located in the European Economic Area (EEA) or the United Kingdom, we process your personal data in accordance with the General Data Protection Regulation (GDPR). Our legal bases for processing include:

• Consent — for example, when you agree to non-essential cookies or analytics and advertising technologies.
• Legitimate interests — to operate, secure, analyze, and improve our website in a way that does not override your fundamental rights and freedoms.
• Legal obligation — when processing is necessary to comply with the law.

Where we rely on consent, you may withdraw that consent at any time. Withdrawing consent does not affect the lawfulness of processing carried out before withdrawal.

7. Third-Party Services

To operate efficiently and keep DRI Calculator free, we rely on reputable third-party service providers. These providers may collect or receive certain information through cookies, tags, or similar technologies in accordance with their own privacy policies.

7.1 Google Analytics

We may use Google Analytics to understand how visitors interact with our website. Google Analytics collects aggregated, non-identifying information such as pages visited, session duration, device type, and approximate location. This helps us improve our content and usability. You can learn more by reviewing Google’s Privacy Policy.

7.2 Google AdSense and Advertising Partners

To support the free availability of this tool, we may display advertisements served by Google AdSense and other advertising partners. Please note the following:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites.
• Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to DRI Calculator and other sites on the internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of third-party vendor cookies for personalized advertising by visiting www.aboutads.info.

We adhere to applicable Google Publisher Policies and Google AdSense program policies. Third-party advertising and analytics technologies are explained further on our separate Cookies Policy page.

7.3 Other Service Providers

We may also use hosting providers, security services, and content delivery networks that process limited technical data strictly to deliver and protect the website. These providers are contractually or operationally expected to handle data responsibly.

8. Data Protection and Security Measures

We take reasonable and appropriate technical and organizational measures to protect the information processed through our website against unauthorized access, alteration, disclosure, or destruction. These measures include:

• Encryption of data in transit using secure HTTPS/SSL connections.
• Minimizing data collection by design, so that little or no personally identifiable information is gathered.
• Performing calculator computations locally in the browser wherever feasible.
• Restricting access to any collected data to authorized purposes only.
• Regularly reviewing our practices and third-party integrations for security and compliance.

While we strive to use commercially acceptable means to protect your information, please understand that no method of transmission over the internet or method of electronic storage is 100% secure. We cannot guarantee absolute security, but we are committed to protecting your data using industry-standard practices.

9. Data Retention

We retain personal data only for as long as necessary to fulfill the purposes described in this Privacy Policy, or as required by applicable law. Because the calculator does not require an account and is designed to avoid retaining identifiable inputs, most information is either processed transiently or stored only in aggregated, anonymized form. Inquiry-related communications are kept only as long as needed to address your request and for reasonable record-keeping.

10. Your Privacy Rights

We respect your right to control your personal data. Depending on your location, you may have some or all of the following rights.

10.1 Rights Under the GDPR (EEA and UK Users)

• Right of access — to request confirmation of whether we process your personal data and to obtain a copy of it.
• Right to rectification — to request correction of inaccurate or incomplete data.

• Not receive discriminatory treatment for exercising any of your privacy rights.

To exercise any of these rights, please contact us using the details in the “Contact Us” section below. We will respond to verifiable requests within the timeframes required by applicable law. We may need to verify your identity before fulfilling certain requests to protect your privacy and security.

11. Children’s Privacy

Protecting the privacy of children is extremely important to us. DRI Calculator is intended for use by adults and is not directed at children under the age of 13 (or the minimum age required in your jurisdiction, such as 16 in parts of the EEA).

We do not knowingly collect personal information from children. If you are a parent or guardian and believe that a child has provided us with personal information, please contact us immediately, and we will take prompt steps to delete such information from our records. Children should always use nutrition and health tools only under the supervision of a parent, guardian, or healthcare professional.

12. International Data Transfers

Our website and the third-party services we use may operate globally. As a result, information may be processed in countries other than your own, including the United States, where data protection laws may differ from those in your jurisdiction. Where required, our service providers and we rely on appropriate safeguards, such as standard contractual clauses, to protect personal data transferred internationally.

13. External Links Disclaimer

DRI Calculator may contain links to third-party websites, resources, or references provided for your convenience and educational benefit. These external sites are operated by independent parties, and we have no control over their content, privacy practices, or security.

The inclusion of any external link does not imply endorsement by DRI Calculator. We are not responsible for the privacy policies or practices of any third-party websites. We strongly encourage you to review the privacy policy of every website you visit before providing any personal information.

14. Medical Disclaimer and Limitation of Liability

The information and estimates provided by DRI Calculator are for general educational and informational purposes only and are based on publicly available population-level reference data. The tool is intended for generally healthy individuals and does not constitute medical, nutritional, or professional advice, diagnosis, or treatment.

Individual nutritional needs vary based on numerous factors that a general calculator cannot fully assess. You should never disregard, avoid, or delay seeking professional medical or dietary advice because of information obtained from this website. Always consult a licensed physician, registered dietitian, or qualified healthcare professional before making any changes to your diet, supplementation, or lifestyle.

To the fullest extent permitted by applicable law, DRI Calculator and its owners, operators, contributors, and affiliates shall not be liable for any direct, indirect, incidental, consequential, or special damages arising out of or in any way connected with your access to, use of, or reliance upon this website, its calculations, or its content. You use this website and its tools entirely at your own discretion and risk.

When we make changes, we will update the “Last Updated” date at the top of this page. Significant changes may be communicated more prominently where appropriate.

We encourage you to review this Privacy Policy periodically to stay informed about how we protect your information. Your continued use of DRI Calculator after any changes constitutes your acceptance of the revised policy.
