Privacy Policy

1. Introduction

CalcNest ("we," "us," or "our") operates the website mycalcnest.com (the "Site"). This Privacy Policy explains how we collect, use, and protect information when you visit and use our Site. By using CalcNest, you agree to the practices described in this policy.

2. Information We Collect

2.1 Calculator Input Data

When you use our calculators, you may enter personal health or financial information such as weight, height, age, income, or expenses. This data is processed entirely in your browser (client-side) and is never transmitted to our servers, stored in any database, or shared with third parties. We do not have access to your calculator inputs or results.

2.2 Analytics Data

We use Google Analytics 4 to understand how visitors interact with our Site. Google Analytics may collect:

• Pages visited and time spent on each page
• Referring website or search engine
• Device type, browser, and operating system
• Approximate geographic location (city/country level)
• Screen resolution and language preference

This data is aggregated and anonymized. We do not use Google Analytics to identify individual users. You can opt out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

3. Cookies

CalcNest uses a minimal number of cookies, primarily set by Google Analytics for the purposes described above. We do not use cookies for advertising, remarketing, or cross-site tracking. You can control or delete cookies through your browser settings at any time.

4. Third-Party Services

Our Site may contain links to external resources such as PubMed, WHO, USDA, and other authoritative sources cited in our calculator and article references. These third-party websites have their own privacy policies, and we are not responsible for their content or practices. We encourage you to review their policies when visiting.

5. Data Security

We take reasonable measures to protect the security of our Site, including using HTTPS encryption for all pages. Since calculator data is processed client-side and never transmitted to our servers, there is no database of user health or financial information that could be breached.

6. Children's Privacy

CalcNest is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will take steps to delete such information.

7. Your Rights

Depending on your jurisdiction, you may have the right to access, correct, or delete personal data we hold about you. Since we do not store personal calculator data, these rights primarily apply to any analytics data collected by Google Analytics. To exercise your rights or ask questions, please contact us at the email below.

8. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. We encourage you to review this page periodically for any changes.
