Privacy Policy

This Privacy Policy explains how WHtRCalc (“we”, “us”, or “our”) collects, uses, and protects information when you visit waisttoheightratio.com and use our free waist to height ratio calculator.

Last updated: August 8, 2026

Quick summary

• You can use the WHtR calculator without creating an account.
• Waist and height inputs are calculated in your browser for the result.
• If you email us or use the contact form, we receive the details you send.
• We may use cookies, analytics, and Google AdSense (or similar ads) to run and improve the free site.
• We do not sell your personal information.

1. Who we are

WHtRCalc operates the Waist to Height Ratio Calculator website — an educational resource that helps people calculate waist to height ratio (WHtR / WTHR) and understand common healthy and higher-risk ranges.

Privacy questions: contact@waisttoheightratio.com or our Contact Us page.

2. Information we collect

2.1 Information you provide

If you contact us by email or through our contact form, we may receive:

• Your name
• Your email address
• Message subject and content
• Any other details you choose to include

We use this only to respond to your request, keep basic support records, and improve the website where relevant.

2.2 Calculator inputs (waist and height)

Our waist to height ratio calculator is designed to run in your browser. Waist, height, and unit selections are processed locally on your device to produce a WHtR result. We do not require a login, and we do not intentionally store your waist or height measurements on our servers as part of the calculation.

If you share a result link, screenshot, or measurement details in an email or form message, those details are treated as information you voluntarily provided.

2.3 Automatically collected technical data

Like most websites, we (and our service providers) may automatically receive limited technical information when you visit, such as:

• IP address
• Browser type and version
• Device type and operating system
• Pages visited, referring URL, and approximate location derived from IP
• Date and time of access

This helps us understand traffic, fix issues, prevent abuse, and keep the site secure.

3. How we use information

We may use information to:

• Operate, maintain, and improve the website and calculator experience
• Respond to messages, privacy requests, and support inquiries
• Monitor performance, security, spam, and abuse
• Understand which educational pages are useful (for example, WHtR chart or how-to guides)
• Comply with legal obligations
• Support free access through advertising partners (including Google AdSense), where ads are enabled

We do not sell your personal information.

4. Cookies and similar technologies

Cookies are small text files stored on your device. We and our partners may use cookies, pixels, local storage, or similar technologies to:

• Remember basic preferences
• Measure site traffic and usage
• Support security and fraud prevention
• Deliver, personalize, and measure advertising (if ads are enabled)

You can control or delete cookies through your browser settings. Blocking some cookies may affect certain features, analytics accuracy, or ad personalization.

5. Advertising and Google AdSense

To keep the waist to height ratio calculator and educational content free, we may display third-party ads, including ads served by Google AdSense and related Google advertising services.

Google and other advertising partners may use cookies or similar technologies to:

• Serve ads based on your visits to this site and/or other websites
• Measure ad performance and prevent fraud or invalid clicks
• Personalize ads where allowed by your settings and applicable law

These partners may collect information such as your IP address, cookie identifiers, and browsing activity. Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to your website or other websites.

Learn more and manage choices:

• How Google uses information from sites that use its services
• Google Privacy Policy
• Google Ads Settings (ad personalization)
• Network Advertising Initiative opt-out
• Your Online Choices (EU)

If we enable consent messaging for ads or cookies in your region (for example, under EU/UK rules), your choices in that message will also control certain advertising and measurement uses.

6. Analytics

We may use analytics tools (for example, Google Analytics or similar services) to understand how visitors use the site — such as which pages are viewed and how people move through the calculator and guides. Analytics providers may set cookies and process technical data on our behalf under their own privacy terms.

7. Third-party services and links

Our website may rely on trusted third parties for hosting, security, analytics, fonts, email delivery, form handling, or advertising. These providers process information only as needed to provide their services and under their own privacy policies.

Our pages may include links to external websites. We are not responsible for the privacy practices or content of those third-party sites. We recommend reviewing their policies before sharing personal information.

8. Data retention

We keep contact messages and related records only as long as reasonably needed to respond, maintain records, improve the site, resolve disputes, or meet legal requirements. Technical and security logs may be retained for a limited period for troubleshooting and abuse prevention.

9. Data security

We take reasonable administrative and technical steps to protect information against unauthorized access, loss, or misuse. No method of transmission over the internet or electronic storage is 100% secure, so we cannot guarantee absolute security.

10. Children’s privacy

Our website is intended for a general audience and is not directed at children under 13 (or the minimum age required in your region). We do not knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us and we will take appropriate steps to delete it.

11. International visitors

If you access the site from outside the country where our servers or service providers operate, your information may be processed in other countries that may have different data-protection laws. By using the site, you understand that this transfer may occur as needed to operate the service.

12. Your privacy rights

Depending on where you live, you may have rights to:

• Request access to personal information we hold about you
• Request correction or deletion
• Object to or restrict certain processing
• Withdraw consent where processing is based on consent
• Opt out of personalized advertising where available
• Ask us to confirm whether we sell or share personal information for cross-context behavioral advertising (we do not sell personal information)

To make a request, email contact@waisttoheightratio.com with the subject line “Privacy Request”. We may need to verify your identity before responding. If you are in the EEA/UK, you may also have the right to lodge a complaint with your local data protection authority.

13. California privacy notice (CCPA/CPRA)

If you are a California resident, you may have additional rights regarding personal information, including rights to know, delete, and correct certain information, and to opt out of “sale” or “sharing” of personal information for cross-context behavioral advertising, where those terms apply.

WHtRCalc does not sell personal information for money. Like many free websites, we may allow advertising and analytics partners to collect identifiers through cookies or similar technologies for ads and measurement. You can limit many of these uses through browser controls, Google Ads Settings, and industry opt-out tools listed above.

To exercise California privacy rights, contact contact@waisttoheightratio.com. We will not discriminate against you for exercising privacy rights.

14. Health information notice

WHtRCalc provides educational tools and information only. Calculator inputs and results are not medical records and are not a substitute for professional medical advice, diagnosis, or treatment. Please do not send sensitive medical details unless they are necessary for a support request.

15. Changes to this Privacy Policy

We may update this Privacy Policy from time to time. When we do, we will change the “Last updated” date at the top of this page. Continued use of the website after changes means you accept the updated policy, unless applicable law requires additional notice or consent.
