Privacy Policy

Last updated: February 2025

At CalcLabHQ, we take your privacy seriously. This policy explains what data we collect and how we use it.

Who We Are

Our website address is: https://calclabhq.com

Calculator Data

All calculations happen locally in your browser using JavaScript. We do not:

• Send your financial information to our servers
• Store your calculator inputs
• Track what numbers you enter
• Require you to create an account

What We May Collect

Like most websites, we may collect anonymous analytics to understand how our site is used:

• Page views — Which calculators are popular
• Device type — Desktop vs. mobile usage
• Country/region — General geographic data
• Referrer — How you found us

This data is aggregated and anonymous. We cannot identify individual users from this information.

Cookies

We may use minimal cookies for:

• Analytics (understanding site usage patterns)
• Remembering your preferences (if any features require it)

We do not use cookies for advertising or tracking across other websites.

Embedded Content

Our calculators may load resources from third-party CDNs (Content Delivery Networks) for:

• Chart libraries (Chart.js)
• PDF export functionality

These services have their own privacy policies. They do not receive your calculator inputs.

Media

If you upload images to our image tools, the processing happens entirely in your browser. We do not upload, store, or transmit your images to any server.

Children's Privacy

Our site is not directed at children under 13. We do not knowingly collect information from children.

Changes to This Policy

We may update this policy occasionally. Changes will be posted on this page with an updated date.
