This Privacy Policy explains how the TDEE & Body Fat Calculator (the “Service”), operated by Varyense (“we”, “us”, “our”), collects, uses, and protects information when you visit the website. By using our calculator and related pages, you agree to the practices described below.

1. Information We Collect

Our calculators are designed to run entirely in your browser. Values you enter (such as age, height, weight, gender, and measurements) are processed locally and are not transmitted to our servers as part of normal calculator use. We collect the following limited information:

Form submissions: if you contact us, we receive the name, email address, subject, and message you provide.
Technical data: standard server logs may record your IP address, browser type, operating system, referring URL, and timestamps.
Locally stored preferences: we use your browser's local storage to remember your theme (light or dark) and recent calculator snapshots so you can keep your history on this device.

2. Sensitive Personal Financial Information

We do not request, process, or store sensitive personal financial information. No sensitive personal financial information is stored unless explicitly submitted through forms on our website. We strongly recommend that you do not share financial account numbers, government IDs, or similar data through our contact form.

3. Cookies

Cookies are small text files stored on your device. We may use cookies and similar technologies for:

Essential functions: remembering your theme preference and basic site settings.
Security: protecting against cross-site request forgery on forms.
Analytics: understanding how visitors use the site in aggregate (see below).

Most browsers let you control or disable cookies through their settings. Disabling cookies may impact some features.

4. Analytics

We may use privacy-respecting analytics tools to measure aggregate traffic and improve our calculators. These tools may collect anonymized usage data, such as page views, device type, country, and session duration. No personally identifiable information is intentionally collected through analytics, and we do not sell analytics data.

5. Third-Party Services

We may rely on a small number of third-party services for hosting, fonts, content delivery, security, and analytics. These providers process limited data on our behalf and are required to keep it confidential. Examples include:

Hosting and CDN providers used to deliver our website.
Web font providers (e.g., Google Fonts) used to render typography.
Analytics platforms used to measure aggregate traffic.

Each third party operates under its own privacy policy, which we encourage you to review.

6. User Privacy and Your Rights

We respect your privacy. Depending on your jurisdiction, you may have the right to:

Request access to the personal information we hold about you.
Request correction or deletion of inaccurate information.
Object to or restrict certain processing of your data.
Withdraw consent where processing is based on your consent.

To exercise these rights, please contact us using the details below.

7. Data Retention and Security

We retain contact form submissions for as long as necessary to respond to your inquiry and comply with our legal obligations. We use reasonable technical and organizational safeguards to protect information transmitted to us. However, no method of internet transmission or storage is 100% secure, and we cannot guarantee absolute security.

8. Children's Privacy

The Service is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us so we can delete it.

9. Changes to This Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top will indicate the most recent revision. Material changes will be highlighted on this page.
