Privacy Policy

Effective Date: October 2026 | Last Mathematically & Legally Audited: October 2026

1. Information We Do Not Collect

Unlike traditional cloud computation engines, our dimensional calculators do not transmit numerical values (length, width, height, radius, or conversion factors) to our servers. All mathematical models run through client-side JavaScript. If you utilize the "Recent Calculations" history feature, those figures remain sandboxed in your browser's private LocalStorage and never leave your personal machine.

2. Advertising & Google AdSense Compliance

This website displays digital advertisements powered by Google AdSense and affiliated third-party advertising vendors. To deliver relevant advertising, Google and certified advertising networks use cookies, including the DoubleClick DART cookie:

• Google, as a third-party vendor, uses cookies to serve ads on our site. Google's use of the DoubleClick cookie enables it and its partners to serve ads to our users based on their visit to our sites and/or other sites on the Internet.
• Third-party vendors and ad networks may also place and read cookies on your browser, or use web beacons to collect information as a result of ad serving on this website.
• Users may opt out of personalized advertising, including the DoubleClick cookie for interest-based advertising, at any time by visiting Google Ads Settings.
• Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative Opt-Out Page or AboutAds.info.

3. Cookies, Log Files, and Web Analytics

Like virtually all modern web properties, we collect non-identifiable technical data through server log files and analytics partners (Google Analytics 4 & Histats) upon user consent. This data includes:

• Internet Protocol (IP) addresses (anonymized where mandated by EU regulations)
• Browser type and version
• Internet Service Provider (ISP)
• Referring and exit pages, date/time stamps, and dwell metrics

This information is used strictly to analyze operational trends, diagnose calculator performance regressions, prevent fraudulent abuse, and enhance user experience.

4. GDPR & European Economic Area (EEA) Rights

If you are a resident of the European Union, European Economic Area, or United Kingdom, you hold fundamental data protection rights under the General Data Protection Regulation (GDPR), including:

• The right to access, rectify, or erase any personal data held about you.
• The right to restrict or object to automated data processing.
• The right to withdraw cookie or analytics consent at any time via our persistent cookie banner.

5. California Consumer Privacy Act (CCPA / CPRA)

Under the California Consumer Privacy Act (CCPA), California consumers have the right to request disclosure of categories of personal data collected, request deletion, and opt-out of the "sale" or "sharing" of personal data. CubicToFeetCalculator does not sell consumer personal information.

6. Contact Form Submissions

When you voluntarily submit inquiries via our Contact Us portal, your name, email address, topic, and message content are transmitted securely to provide technical customer support. We retain inquiry correspondence only as long as necessary to resolve your request and never distribute contact details to third-party marketing lists.
