Privacy Policy

Last updated: July 19, 2026

This Privacy Policy explains what information SmartDietChoices (smartdietchoices.com, the site) collects, how it is used, who it is shared with, and the choices and rights you have. We aim to collect as little as possible. By using the site you agree to the practices described here. If you do not agree, please stop using the site.

Who we are

SmartDietChoices operates smartdietchoices.com, a free collection of nutrition and body-composition calculators. For any privacy question you can contact us by email at tophealthies@gmail.com or by phone at +1 571-591-1790. For the purposes of applicable data protection law, SmartDietChoices is the data controller for the limited personal data described below.

Information we collect

We collect very little, and most of it is gathered automatically to keep the site running and to understand usage in aggregate:

  • Calculator inputs: the numbers you type into our calculators, such as weight, height, age, and goals. These are processed entirely in your browser. They are not sent to our servers, not saved to your device, and not shared with anyone. Refreshing or closing the page clears them.
  • Usage and device data: when you visit, our analytics and advertising partners may automatically receive standard information such as your approximate location (derived from IP address), device and browser type, operating system, referring page, pages viewed, time on page, and anonymized interactions like completing a calculation or opening an FAQ.
  • Cookies and similar technologies: small files and identifiers stored by your browser, used for analytics and advertising as described below.
  • Information you send us: if you email or call us, we receive whatever you choose to share, used only to respond to you.

How we use information

We use the information above to operate and secure the site, understand which calculators are useful and how visitors arrive, fix errors and improve the tools, display advertising that keeps the site free, and respond to messages you send us. We do not sell your personal information for money.

Analytics

We use Google Analytics 4 to understand how the site is used in aggregate. Google Analytics may set cookies and collect information such as your approximate location, device and browser type, pages viewed, and anonymized interactions. We enable IP anonymization. This data is aggregated and helps us improve the tools; it is not used by us to identify you personally. Google processes this data under its own privacy terms, available at policies.google.com/privacy.

Advertising and Google AdSense

We display advertising to keep the site free, including through Google AdSense and its advertising partners. The following disclosures apply:

  • Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
  • Google's use of advertising cookies, including the DoubleClick DART cookie, enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet.
  • You may opt out of personalized advertising by visiting Google Ads Settings.
  • You can also opt out of a third-party vendor's use of cookies for personalized advertising through aboutads.info/choices and youronlinechoices.eu for European users.
  • Some third-party advertising partners may place and read their own cookies, web beacons, and similar technologies. Their use of this technology is governed by their own privacy policies, not this one. A list of Google's advertising partners is available in the Google Ads Settings linked above.

For more on how Google uses information from sites that use its services, see policies.google.com/technologies/partner-sites.

Cookies and your choices

Cookies are small text files stored by your browser. We and our partners use them for analytics (to measure usage) and advertising (to serve and, in some cases, personalize ads). You can control or delete cookies through your browser settings, and you can opt out of Google Analytics using the Google Analytics Opt-out Browser Add-on. Blocking cookies will not stop the calculators from working, since they do not rely on cookies. Where required by law, we request your consent before setting non-essential cookies through a consent banner, and you can change your choice at any time.

Consent for users in the European Economic Area and United Kingdom

If you are in the EEA or the UK, we and our advertising partners rely on your consent to set non-essential cookies and to use data for personalized advertising, in line with the General Data Protection Regulation (GDPR) and Google's EU user consent policy. Our legal bases for processing are your consent (for advertising and analytics cookies) and our legitimate interest in operating and securing the site. You have the right to access, correct, delete, or restrict processing of your personal data, to object to processing, to data portability, and to withdraw consent at any time. You may also lodge a complaint with your local data protection authority. To exercise any right, email tophealthies@gmail.com.

Your California privacy rights

If you are a California resident, the California Consumer Privacy Act (CCPA), as amended by the CPRA, gives you the right to know what personal information is collected, to request deletion, to correct inaccurate information, and to opt out of the sale or sharing of personal information. We do not sell personal information for money. Certain advertising cookie activity may be considered a sale or share under California law; you can opt out using the advertising controls listed above or by contacting us. We will not discriminate against you for exercising your rights. To make a request, email tophealthies@gmail.com.

Data retention

Calculator inputs are never stored, so there is nothing to retain. Aggregated analytics data is retained according to Google Analytics settings, typically up to 14 months. Advertising data is retained by our partners under their own policies. Emails you send are kept only as long as needed to handle your request.

Data we do not collect

We do not require you to create an account, and we do not ask for or store your name, email, or health information through the calculators. The health-related numbers you enter stay in your browser and never reach us.

Children's privacy

This site is intended for a general adult audience and is not directed to children under 13 (or the minimum age required in your country). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.

International visitors

The site is operated from the United States and served globally. If you access it from another country, you understand your information may be processed in the United States and other countries where our service providers operate, which may have different data protection rules than your own.

Security

We take reasonable technical and organizational measures to protect the limited data we handle. No method of transmission or storage over the internet is completely secure, so we cannot guarantee absolute security.

Changes to this policy

We may update this policy as the site evolves, for example when advertising or analytics practices change. Material changes will be reflected here with a new date at the top. Your continued use of the site after changes are posted means you accept the updated policy.
