Privacy Policy
Effective Date: April 19, 2026
Last Updated: April 19, 2026
TDEEMacroCalculator.com is a free nutrition and fitness calculator tool operated by SquarepegIdeas. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your personal data. By using our website, you agree to the collection and use of information in accordance with this policy.
We are committed to protecting your privacy. Our tools are designed to work without requiring you to create an account or share personal information. The calculations you perform stay in your browser.
Information We Collect
Information You Provide
Our calculators run entirely in your browser. The numbers you enter - including age, weight, height, activity level, and dietary preferences - are processed locally and used only to display your results. This information is not transmitted to our servers or stored beyond your current browser session, except when you use the URL sharing feature, which encodes your inputs in the URL for your own use.
AI Features
When you use our AI Meal Plan Generator or What's in My Fridge recipe tool, your inputs - including macro targets, ingredients list, and dietary preferences - are sent to our server and forwarded to Anthropic's Claude AI model to generate your response. These inputs are processed to generate your results and are not stored by us after your request is completed. Please review Anthropic's Privacy Policy and Vercel's Privacy Policy for their data handling practices.
Analytics Data
We use Vercel Analytics to collect anonymous usage data including page views, session duration, general geographic location at the country or region level, device type, and browser type. This data helps us understand how visitors use our site so we can improve it. Vercel Analytics is privacy-friendly by design: it does not use cookies, does not fingerprint users, and does not track individuals across sessions or sites. No personally identifiable information is collected through our analytics.
Advertising
We display advertisements through Google AdSense. AdSense uses cookies to serve ads based on your prior visits to our website and other sites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and other sites on the internet. You may opt out of personalized advertising by visiting Google's Ads Settings.
Information We Do NOT Collect
We do not collect name, email address, physical address, payment information, health records, or any other personally identifiable information. We do not require account creation or registration to use any feature on this site.
How We Use Information
- Provide and improve our calculator tools and AI features

- Understand which features are most useful to our visitors
- Display relevant advertisements through Google AdSense
Cookies
Our website uses the following types of cookies and local storage:
Advertising cookies: Google AdSense uses cookies including DoubleClick cookies to serve relevant advertisements and measure ad effectiveness. These are set by Google's ad-serving technology.
Functional storage: We store your unit preference (Imperial/metric) and theme preference (dark/light) in your browser's localStorage. These are not transmitted to any server and are used solely to remember your display preferences.
Vercel Analytics does not set any cookies. You can control advertising cookies through your browser settings or Google's Ads Settings. Disabling advertising cookies may affect ad relevance but will not affect calculator functionality.

Data Retention

EU and International Visitors
Vercel Analytics does not use cookies, does not collect personally identifiable information, and does not track users across sessions. Our calculator inputs are processed entirely in your browser and never sent to our servers. If you use our AI features, your inputs are processed by Vercel and Anthropic's Claude API under their respective data processing terms. You may choose not to use the AI features if you prefer not to transmit any data.
Children's Privacy
Our website is not directed at children under 13 years of age. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has provided us with personal information, please contact us at hello@tdeemacrocalculator.com.
Your Rights
Since we do not collect personally identifiable information, most data rights requests do not apply to data we hold. For data processed by third-party services such as Google AdSense or Vercel, requests should be directed to those services. For any questions about data we may hold, contact us at hello@tdeemacrocalculator.com.
