Privacy Policy

Last updated: August 2, 2026

1. Overview

Macrocalculator (“we,” “us,” or “our”) operates macrocalculator.pro (the “Site”). This Privacy Policy explains what information we collect when you use our calculators and tools, how we use it, and the choices available to you. By using the Site, you agree to the practices described in this policy.

We built Macrocalculator to be a free, no-signup tool. We do not require an account to use any calculator on this Site, and we aim to collect as little personal information as possible.

2. Information We Collect

We collect information in the following ways:

• Calculator inputs: Values you enter (such as age, weight, height, activity level, or goal) are processed in your browser to generate your results. These inputs are not tied to your identity and are not stored on our servers unless explicitly stated.
• Usage data: Like most websites, we automatically collect certain technical information when you visit, including your IP address, browser type, device type, pages viewed, and time spent on the Site.
• Newsletter sign-up: If you subscribe to our newsletter, we collect your email address to send updates, recipes, and macro tips.
• Contact form submissions: If you contact us directly, we collect the information you provide, such as your name, email address, and message.

3. How We Use Your Information

We use the information we collect to:

• Provide, operate, and improve our calculators and tools
• Understand how visitors use the Site so we can make it more useful
• Send newsletter content to subscribers who have opted in
• Respond to inquiries submitted through our contact form
• Detect, prevent, and address technical issues or abuse

We do not sell your personal information to third parties.

4. Cookies & Tracking Technologies

The Site uses cookies and similar technologies to remember your preferences (such as unit settings) and to understand aggregate usage patterns. You can control or disable cookies through your browser settings; note that some features of the Site may not function properly if cookies are disabled.

Cookie Type	Purpose
Essential	Required for basic site functionality (e.g. remembering unit preference)
Analytics	Helps us understand how visitors use the Site in aggregate
Preference	Remembers settings like your last calculator inputs

5. Third-Party Services

We may use third-party services for analytics, hosting, and email delivery. These providers may collect information sent by your browser as part of a web page request, such as cookies or your IP address, in accordance with their own privacy policies. We encourage you to review the privacy policies of any third-party service we use.

6. Data Sharing & Disclosure

We do not share your personal information with third parties except in the following circumstances:

• With service providers who help us operate the Site (e.g. hosting or email delivery), under confidentiality obligations
• If required by law, regulation, or valid legal process
• To protect the rights, property, or safety of Macrocalculator, our users, or others
• In connection with a business transfer, such as a merger or acquisition

7. Data Retention

Calculator inputs processed in your browser are not retained by us. Newsletter and contact form data is retained for as long as necessary to fulfill the purpose it was collected for, or until you request its deletion.

8. Your Rights & Choices

Depending on your location, you may have rights regarding your personal information, including the right to:

• Access the personal information we hold about you
• Request correction or deletion of your personal information
• Unsubscribe from our newsletter at any time via the link in any email

9. Children’s Privacy

Macrocalculator is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us so we can remove it.

10. Data Security

We take reasonable technical and organizational measures to protect the information we collect. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.

11. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or for legal, operational, or regulatory reasons. We will post the updated policy on this page with a revised “Last updated” date. We encourage you to review this page periodically.
