Privacy Policy

This Privacy Policy explains how CalcNest(“we,” “us,” or “our”), available at https://calc.jsonbug.com, collects, uses, and shares information when you visit our website (the “Site”). By using the Site, you agree to the practices described in this policy.

1. Information We Collect

Calculator inputs

The numbers and dates you enter into our calculators are processed entirely in your web browser. They are never transmitted to, stored on, or visible to our servers.

Automatically collected information

Like most websites, we and our service providers may automatically collect certain technical information when you visit, including your IP address, browser type, device type, operating system, referring URLs, pages viewed, and the dates and times of visits. This information is collected through cookies and similar technologies and is used in aggregate to understand how the Site is used.

Information you provide

If you contact us by email, we receive your email address and the contents of your message. We use this information only to respond to you.

2. Cookies and Similar Technologies

Cookies are small text files stored on your device. We use cookies and similar technologies (such as web beacons and local storage) to operate the Site, analyze traffic, and support advertising. You can control cookies through your browser settings — most browsers let you block or delete cookies. Disabling cookies may affect some features of the Site.

3. Advertising and Third Parties

We may display advertisements served by third-party advertising partners, including Google AdSense. These partners may use cookies and similar technologies to collect information about your visits to this and other websites in order to show you personalized (interest-based) advertising.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
• Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this Site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info/choices.

We do not control the data collection practices of third-party ad networks. Their use of information is governed by their own privacy policies.

4. Analytics

We may use analytics services to measure traffic and usage trends. These services collect information sent by your browser, such as pages visited and time on site, in aggregated form that does not personally identify you.

5. How We Use Information

• To operate, maintain, and improve the Site and its tools
• To measure which calculators are most useful
• To display advertising that supports the free Site
• To respond to your messages and requests
• To detect abuse and protect the security of the Site

6. Sharing of Information

We do not sell your personal information. We share information only with service providers who help us operate the Site (such as hosting, analytics, and advertising partners described above), or when required by law.

7. Data Retention

Aggregated analytics data is retained only as long as needed for the purposes described in this policy. Emails you send us are retained as long as necessary to handle your request.

8. Children's Privacy

The Site is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, please contact us and we will delete it.

9. Your Rights and Choices

Depending on where you live, you may have rights regarding your personal information, including the right to access, correct, or delete it, and the right to opt out of certain processing. Residents of the European Economic Area and the United Kingdom have rights under the GDPR; California residents have rights under the CCPA/CPRA, including the right to opt out of the “sale” or “sharing” of personal information. To exercise any of these rights, contact us at the address below.

10. Security

We use reasonable technical and organizational measures to protect information. However, no method of transmission over the Internet is completely secure, and we cannot guarantee absolute security.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page. Continued use of the Site after changes take effect constitutes acceptance of the revised policy.
