We will respond to your request within 30 days. You may need to verify your identity before we can fulfill your request.

Children's Privacy

CalcFFMI.com is not intended for users under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately at privacy@calcffmi.com and we will delete it.

Disclaimer

Medical Disclaimer: The calculators and information provided on CalcFFMI.com are for educational and informational purposes only. They are not intended to be a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or qualified health provider with any questions regarding your health, fitness, or nutrition.

Accuracy Disclaimer: While we strive for accuracy in our calculators and content, results are estimates and may not be perfectly accurate for every individual. Factors like genetics, body composition, and measurement accuracy can affect results.

Privacy at a Glance

This section summarizes the policy in plain language and should be read together with the detailed provisions above. CalcFFMI is designed around fitness calculators and educational content. The existing policy states that calculator values are generally processed in the browser unless a user deliberately chooses a feature that saves information. Other information, such as basic device, usage, account, or communication data, may be handled when necessary to operate the website, understand usage, respond to users, or provide optional features.

Privacy choices can depend on which features you use. A visitor who only reads an article may provide less direct information than a user who creates an account, saves results, submits a contact form, or subscribes to communications. You should review the sections describing cookies, third-party services, retention, and privacy rights so you understand the differences.

Fitness Calculator Data and Sensitive Context

Fitness calculators can ask for information such as age, sex, height, weight, activity level, body-fat estimates, and performance data. These values may feel personal because they describe the body and fitness goals. The policy above explains how calculator inputs are handled and when saved data may be retained. Users should avoid entering information they do not want associated with an account or saved history.

Calculator outputs are estimates for educational and planning purposes. They should not be treated as medical records or medical diagnoses. If you use the FFMI Calculator, Body Fat Calculator, or TDEE Calculator, review each tool’s assumptions before deciding whether to save or share a result.

Local Browser Processing and Saved Features

There is an important distinction between information processed temporarily in the browser and information deliberately saved to an account or feature. Local processing can allow a calculator to display a result without sending every input value to a server. Saved features, by contrast, may require storage so that data remains available later. If a save option is offered, read the interface carefully and only save information you want retained.

Browser storage can also be used for preferences such as units or settings. Clearing cookies or browser storage may remove some locally remembered preferences. Likewise, blocking essential browser storage may affect functions that depend on it. These behaviors vary by browser and by how a feature is implemented.

Account and Progress-Tracking Information

If CalcFFMI offers accounts or a Progress Tracker, account-related data may be different from anonymous calculator use. An account can make it possible to associate saved results, progress entries, preferences, and authentication information with a particular profile. Users should protect account credentials, use a unique password, and sign out on shared devices.

If you no longer want saved information associated with an account, use available account controls or contact CalcFFMI using the privacy contact method listed in this policy. Some information may need to be retained where necessary for security, dispute resolution, legal requirements, or record integrity, depending on applicable law and the nature of the request.

Analytics, Measurement, and Site Improvement

Web analytics can help website operators understand which pages are used, whether visitors encounter technical problems, and how devices or browsers affect performance. The policy identifies analytics as one category of automatically collected information. Analytics data is generally more useful when viewed in aggregate, such as page popularity, session patterns, or device categories, rather than as a fitness profile for an individual visitor.

Where consent or opt-out choices are required by applicable law, users may be presented with cookie or privacy controls. Browser settings can also limit certain categories of storage, although doing so may affect some site features. Refer to the cookie section above for the categories described by CalcFFMI.

Advertising and Third-Party Technologies

If advertising or third-party services are enabled, those services may use their own technologies under their own terms and privacy policies. CalcFFMI does not control every independent third party’s privacy practices. Users who want to understand a third-party service should review the privacy information linked or identified for that provider and use available opt-out or consent controls when applicable.

A third-party link does not mean that CalcFFMI receives every piece of information collected by that provider. Likewise, a third party can have its own legal basis, retention period, or account relationship with the user. This policy describes CalcFFMI’s stated practices; third-party notices describe the third party’s practices.

Data Minimization and Purpose Limitation

A useful privacy principle is to collect only information reasonably connected to a defined purpose and to avoid retaining it longer than necessary for that purpose. The detailed retention section above describes the periods currently stated for different categories. Where a feature can work without saving a calculator value, users may prefer the non-saved option. Where saving is useful, users should understand that persistence is the point of the feature.

CalcFFMI may update features over time. If a new feature materially changes what information is collected or how it is used, this policy should be updated so visitors can review the change. The “Last Updated” date helps indicate when the policy was most recently revised.

Security Responsibilities Shared With Users

Website security is a shared process. CalcFFMI describes measures such as encrypted transmission and access controls, but users also influence security through their own devices and account habits. Keep browsers updated, avoid reusing passwords, be cautious on shared computers, and do not send sensitive information through ordinary contact forms unless the form specifically requests it and you understand why it is needed.

No website can promise absolute security. If you believe an account or communication has been compromised, contact the site promptly and change relevant passwords. Do not include unnecessary health, payment, or identity documents in an ordinary support request.

Privacy Rights Requests: What to Include

Where applicable, a user may request access, correction, deletion, restriction, portability, or another right recognized in the user’s jurisdiction. A useful request should identify the email address or account involved, clearly describe the action requested, and provide enough information for CalcFFMI to locate the relevant records without requesting excessive additional data.

Identity verification may be necessary before disclosing or deleting personal information. This helps prevent another person from using a privacy request to obtain or erase someone else’s data. The exact verification method should be proportionate to the sensitivity of the request and the information involved.

International Visitors

Privacy rights and consent requirements vary by location. This policy uses general language because CalcFFMI may be accessed internationally. Nothing in this policy is intended to remove rights that cannot lawfully be waived. If local law gives you specific privacy rights, you may contact CalcFFMI using the privacy contact information above to ask how those rights apply to your use of the site.

Children and Teen Users

The policy above explains the site’s position regarding children under 13 and parental supervision for younger users. Fitness calculators can generate numbers that are easily misinterpreted, especially during growth and development. Parents, guardians, and qualified health professionals should be involved when minors use body-composition or nutrition information. General adult fitness reference ranges may not be appropriate for children or adolescents.

Links to Other CalcFFMI Pages

This Privacy Policy applies to privacy practices described for CalcFFMI, while individual tools provide their own functional context. For example, the FFMI Calculator explains the inputs used for an FFMI estimate, and the Body Fat Calculator explains body-fat estimation. The Terms of Service addresses site-use terms, while the Contact page provides a general communication route.

Policy Review Checklist for Users

  • Read what calculator and account information may be processed or saved.
  • Review the cookie categories and third-party services that apply to your visit.
  • Use browser or consent controls if you want to limit optional tracking where available.
  • Do not save fitness information you do not want retained.
  • Protect account credentials and avoid sharing unnecessary sensitive information through contact forms.
  • Use the privacy contact route if you want to exercise an applicable data right.

Important: This page describes CalcFFMI’s stated privacy practices and is not legal advice to visitors or other website owners. Site operators should verify that the policy accurately matches the technologies, vendors, retention settings, account features, and legal requirements actually in use.

Browser Controls and Practical Privacy Choices

Modern browsers provide controls for cookies, site storage, location permissions, notifications, camera access, and other device capabilities. CalcFFMI visitors can use these controls in addition to any consent interface provided by the website. Blocking all storage may reduce functionality, while selectively limiting optional tracking can preserve more site features. Browser documentation explains how to clear stored data for a specific site.

If you use a shared or public device, avoid saving login credentials in the browser and sign out after using account features. Clearing browsing data can reduce local traces, but it may also remove preferences or locally saved information. Users should decide which tradeoff fits their situation.

Email, Newsletter, and Contact Communications

If you voluntarily send an email, submit a contact form, or subscribe to updates, the information in that communication is necessarily processed so CalcFFMI can deliver or respond to the request. Do not include unnecessary sensitive details. For example, a technical support question about a calculator usually does not require identity documents, complete medical history, or unrelated health records.

Marketing messages should include a practical way to unsubscribe where required and where such communications are offered. Transactional or service-related messages may be treated differently because they can be necessary to operate an account, respond to a request, or communicate a policy or security issue.

Policy Accuracy and Future Feature Changes

Privacy policies should match the website that is actually operating. If CalcFFMI changes analytics providers, adds account features, introduces cloud-saved progress photos, changes advertising technology, or alters retention practices, the policy should be reviewed and revised. Users can use the Last Updated date as one signal that the notice has been maintained.

Likewise, if a feature is described as local browser processing, the site owner should periodically verify that implementation. A privacy notice is most useful when technical behavior, vendor configuration, and written disclosures remain aligned.

Privacy Questions Before Using a Feature

Before using a new account, save, upload, or communication feature, ask what information the feature needs, whether saving is optional, how long the information may remain available, and how you can delete or export it if applicable. This simple check helps users make informed choices instead of assuming every feature handles information in the same way.

If a feature requests information that appears unrelated to its purpose, users can contact CalcFFMI for clarification before submitting it. Privacy is easier to protect when collection is understandable and proportional from the start.

Questions About This Privacy Policy

If any section is unclear, users can contact CalcFFMI before providing optional information. A privacy notice should be understandable enough that a visitor can identify the major categories of data, purposes, storage choices, third parties, and available rights. Questions can also help identify where future revisions need clearer language.

Because technologies and laws change, users should review the current version rather than relying on a copy saved long ago.
