Privacy Policy

Effective Date: April 19, 2026

Last Updated: June 28, 2026

TDEEMacroCalculator.com is a free nutrition and fitness calculator tool operated as TDEE Macro Calculator. 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. Calculator inputs stay in your browser unless you choose to include them in a contact message or share URL.

Information We Collect

Calculator Inputs

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.

Contact Form Information

If you use the contact form, we collect the name, email address, subject, and message you submit so we can read and respond to your inquiry. The contact form is optional. Messages are sent to us through Resend and delivered to our email inbox. Do not send sensitive health, financial, or account information through the contact form.

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.

We also use Google Analytics 4, which loads Google's gtag.js and uses cookies such as _ga to measure how visitors use the site. This includes which pages are viewed, your approximate location, device and browser type, and the source that referred you. Where consent is required, Google Analytics only sets these cookies after you accept. See Your Consent Choices below for how that works.

We use Vercel Speed Insights to measure page performance and Web Vitals. It is cookieless and collects no personally identifiable information.

Advertising

When advertising is active on this site, ads are served by Google AdSense. In that case Google and its partners may use cookies, including DoubleClick cookies, to serve and measure ads based on your visits to our site and other sites. Ads are not always running, so you may see none.

You can opt out of interest-based advertising through the Digital Advertising Alliance at optout.aboutads.info, the Network Advertising Initiative at optout.networkadvertising.org, and Google's Ads Settings.

Information We Do NOT Collect

We do not collect payment information, physical address, health records, or account credentials. We do not require account creation or registration to use any calculator on this site. Contact details are collected only if you voluntarily submit the contact form or email us directly.

Cookies

Our website uses the following types of cookies and local storage:

Analytics cookies: Google Analytics 4 sets cookies such as _ga to distinguish visitors and measure how the site is used. Where consent is required, these are set only after you accept.

Advertising cookies: When AdSense is enabled, Google and its advertising partners may use cookies, including DoubleClick cookies, to serve relevant advertisements and measure ad effectiveness. These are set by those ad-serving technologies.

Functional storage: We store your unit preference (Imperial or metric) in your browser's localStorage. This value is not transmitted to any server and is used solely to remember your display preference between visits. If you are in the EEA, UK, or Switzerland, we also store your consent choice in localStorage under the key tmc-consent for about six months. That value is client-only, is never sent to a server, and clearing your site data resets it.

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

We do not store calculator inputs on our servers. Contact form messages are delivered through Resend to our email inbox and may be retained as ordinary business correspondence. Vercel Analytics retains aggregate, anonymized usage data in accordance with Vercel's data retention policy. Google retains Google Analytics data according to its own retention settings. Your EEA, UK, or Swiss consent choice is stored locally in your browser for about six months, not on our servers.

We enforce per-IP rate limits on form submissions and certain API endpoints, namely the contact form and the OG image endpoint, to protect the site against abuse. Before it is used, your IP address is hashed with SHA-256 plus a server-side salt. Only that short-lived hash is held in memory. The raw IP is never written to disk or logs, and no third party receives it.

Your Consent Choices

We use Google Consent Mode v2 to control when analytics and advertising cookies are set. Four signals are managed: analytics storage, ad storage, ad user data, and ad personalization. If you visit from the EEA, the UK, or Switzerland, all four default to denied and a banner asks you to choose. Nothing in those categories is set until you select Accept. Choose Reject and they stay denied.

Visitors outside those regions default to granted, and you can opt out at any time through your browser settings and the advertising opt-out links above. Your choice is stored locally for about six months. Clearing your site data removes it, and the banner asks again on your next visit.

EU and International Visitors

Our calculator inputs are processed entirely in your browser and never sent to our servers. Vercel Analytics is cookieless, collects no personally identifiable information, and does not track users across sessions. Google Analytics and our advertising partners may set cookies as described above, and for EEA, UK, and Swiss visitors that happens only after you accept on the consent banner. See Your Consent Choices for how to change your decision.

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 athello@tdeemacrocalculator.com.

Your Rights

Since calculator inputs are not sent to our servers, most calculator-related data rights requests do not apply to data we hold. For contact form messages, you may ask us to review or delete correspondence associated with your email address. For data processed by Google services, requests should be directed to Google. EEA, UK, and Swiss visitors can withdraw analytics or advertising consent at any time by clearing site data, which makes the consent banner ask again, or by using the advertising opt-out links above. For any questions about data we may hold, contact us at hello@tdeemacrocalculator.com.

Changes to This Policy

We may update this Privacy Policy from time to time. We will note the date of the last update at the top of this page. Your continued use of our site after changes constitutes acceptance of the updated policy.
