1. Introduction & Scope

TDEECal.com ("TDEECal," "we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website https://tdeecal.com/ (the "Site") and use our TDEE calculator (the "Service").

Please read this privacy policy carefully. By accessing or using our Site, you acknowledge that you have read, understood, and agree to be bound by this Privacy Policy. If you do not agree with our policies and practices, please do not use our Site.

πŸ’‘
Our Core Privacy Principle: We designed our calculator to work entirely in your browser. Your health data (age, weight, height, etc.) is processed locally on your device and is never transmitted to our servers. We literally cannot see or access the information you enter into the calculator.

What This Policy Covers

  • The TDEECal.com website and all pages within it
  • Our TDEE calculator tool
  • Any forms on our site (such as contact forms)
  • Any future services we may offer

What This Policy Does NOT Cover

  • Third-party websites we may link to
  • Third-party services' own data practices (see Section 7)
  • Other websites or services not operated by TDEECal

πŸ›‘οΈ Our Privacy Guarantee for Calculator Data

πŸ”’
100% Client-Side Processing

All calculations happen in your web browser using JavaScript. Your data never leaves your device.

🚫
No Server Transmission

We do not send your calculator inputs to any server, database, or third party.

πŸ‘οΈ
We Cannot See Your Data

We have no technical ability to access, view, or retrieve the information you enter.

πŸ—‘οΈ
Automatic Clearing

When you close the calculator or navigate away, your entered data is gone (unless you save it locally).

Technical Note: You can verify this yourself by using your browser's developer tools (Network tab) while using the calculator. You will see that no requests containing your personal data are sent to any server.

4. Automatically Collected Data

When you visit our Site, certain information is collected automatically by our servers and analytics tools. This is standard for virtually all websites on the internet.

What We Automatically Collect

πŸ“± Device Information

  • Browser type and version (e.g., Chrome 120, Safari 17)
  • Operating system (e.g., Windows 11, iOS 17)
  • Device type (desktop, mobile, tablet)
  • Screen resolution
  • Language preferences

🌐 Usage Information

  • Pages visited on our Site
  • Time spent on each page
  • Links clicked
  • Referring website (how you found us)
  • Date and time of visit

πŸ“ Location Information

  • Country (derived from IP address)
  • General region/city (approximate only)
  • We do NOT collect precise GPS location

πŸ”— Network Information

  • IP address (anonymized/truncated)
  • Internet service provider (general)
  • Connection type

Why We Collect This

  • Improve our Site: Understanding how visitors use the site helps us make it better
  • Technical optimization: Ensuring the site works well on different devices and browsers
  • Security: Detecting and preventing abuse, attacks, or fraudulent activity
  • Performance: Monitoring site speed and identifying issues
ℹ️
Note on IP Addresses: We use IP anonymization where available. In Google Analytics, for example, the last octet of your IP address is removed before storage, making it impossible to identify you personally from the IP address alone.

5. Cookies & Tracking Technologies

What Are Cookies?

Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work more efficiently and provide information to website owners.

Cookies We Use
