Privacy Policy

1. Overview

This Privacy Policy explains how CalculatorHub ("we," "us," or "our") collects, uses, and protects information when you use our website and calculators. We built CalculatorHub with a simple principle in mind: the numbers you type into a calculator are yours. We don't require an account, and calculator inputs are processed in your browser — they are not stored on our servers or associated with your identity.

2. Information We Collect

We collect limited information to operate and improve the site:

• Calculator inputs: Values you enter into a calculator (income, loan amounts, dates, etc.) are processed locally in your browser to generate results and charts. We do not transmit or store these values on our servers.
• Usage analytics: We may use standard analytics tools to understand which pages are visited and how the site performs, using aggregated, non-identifying data such as page views and browser type.
• Contact information: If you email us, we retain that correspondence (including your email address) to respond to your inquiry.
• Cookies: We may use cookies for basic site functionality and analytics. You can disable cookies through your browser settings; this may affect some site features.

3. How We Use Information

Aggregated usage data helps us understand which calculators are most useful and where the site can be improved. Contact information is used solely to respond to your inquiries. We do not sell personal information to third parties.

4. Third-Party Services

We may use third-party services for analytics or site infrastructure (such as hosting providers). These providers may collect standard technical information (like IP address and browser type) as part of delivering the site to you. We do not control these providers' independent data practices; we encourage you to review their respective privacy policies if you have concerns.

5. Data Security

We take reasonable technical measures to protect information we do collect, but no method of transmission or storage is 100% secure. Because calculator inputs are processed client-side and not stored on our servers, sensitive financial figures you enter into a calculator are not retained by us after you leave the page.

6. Children's Privacy

CalculatorHub is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

7. Your Choices

You can use most CalculatorHub tools without providing any personal information at all. You may disable cookies in your browser, and you may contact us at any time to ask what information we hold about correspondence you've sent us.

8. Do Not Track Signals

Some browsers offer a "Do Not Track" (DNT) setting. There is currently no industry standard for how websites should respond to DNT signals, and CalculatorHub does not currently alter its data practices in response to a browser's DNT setting. Regardless of this setting, calculator inputs are still processed only in your browser and are not transmitted to or stored on our servers, as described in Section 2.

9. International Visitors

CalculatorHub is operated from the United States, and any information we do collect (such as correspondence you send us) may be processed and stored in the United States. If you are visiting from outside the United States, you understand that any information you choose to share with us, such as through the Contact page, will be transferred to and processed in the United States, which may have different data protection laws than your home country.

10. Data Retention

Because calculator inputs are never transmitted to or stored on our servers, there is nothing to retain or delete on that front — that data simply doesn't exist outside your own browser session. Correspondence sent to us through the Contact page is retained for as long as reasonably necessary to address your inquiry and for a limited period afterward for our internal records, after which it may be deleted as part of routine account and inbox maintenance.

11. California and Other State Privacy Rights

Depending on your state of residence, you may have additional rights regarding personal information, such as the right to know what categories of information a business has collected about you, the right to request deletion, and the right to opt out of the sale of personal information. CalculatorHub does not sell personal information as defined under applicable state privacy laws. If you have questions about your rights under a specific state's privacy law, you can reach us using the contact information in Section 13.

12. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. Material changes will be reflected by an updated "Last updated" date at the top of this page, and where changes are significant, we may provide a more prominent notice on the site. We encourage you to review this page periodically to stay informed about how we handle information.

13. Contact Us

Questions, concerns, or requests related to this Privacy Policy — including any state-specific privacy rights described in Section 11 — can be sent to [email protected]. We aim to respond to privacy-related inquiries within a reasonable timeframe.
