Privacy Policy & Cookie Disclosure
1. Overview & Data Controller
Road Base Calculator ("we", "our", or "the Platform"), accessible at https://roadbasecalculator.com, provides civil engineering estimation tools, volume-to-weight algorithms, and aggregate construction guides.
We are committed to user privacy and data minimization. This Privacy Policy outlines what information is collected, how it is used, your choices regarding cookies, and your rights under applicable privacy regulations, including the European General Data Protection Regulation (GDPR), the UK Data Protection Act / PECR, and California Consumer Privacy Act (CCPA/CPRA). If you have questions, contact our desk at estimator@roadbasecalculator.com.
2. Zero Input Storage (Client-Side Computing)
We believe technical estimation tools should not log private project data. All dimensional inputs—including length, width, radius, compacted depth, material selections, and budget entries—are computed strictly within your web browser using client-side JavaScript.
We do not transmit, log, store, or sell your project square footage, aggregate tonnage, or cost figures on our servers.
3. Website Analytics & Google Analytics 4
We use Google Analytics 4 (GA4), a web analytics service provided by Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA), to understand aggregate traffic patterns, browser screen sizes, and device performance.
Under our Google Consent Mode v2 implementation:
- Analytics storage cookies are denied by default until you click "Accept Analytics" on our cookie banner.
- IP addresses are masked and anonymized by default.
- Data collected includes pseudonymous client identifiers, approximate geographic region (country/city), referring URL, browser type, and pages viewed.
- Data is retained according to standard Google Analytics retention schedules (14 months maximum for user-level data) and is never combined with personally identifiable information.
4. Cookies & Tracking Technologies
A cookie is a small data file placed on your device by your web browser. We categorize cookies into three clear classifications:
Necessary for site security, cross-origin resource isolation, remembering your measurement unit preference (Imperial vs. Metric), and recording your cookie consent preferences (rbc_cookie_consent, duration: 12 months). These do not track personal identity and cannot be deactivated.
Set by Google Analytics (_ga, _ga_*) to distinguish unique visitors and measure aggregate page traffic. These cookies are only activated if you affirmative grant analytics consent on our consent banner.
Set by Google AdSense and certified third-party ad technology partners to serve contextual or personalized advertisements and prevent ad repetition. These cookies are only activated with affirmative user consent in relevant jurisdictions.
You can revoke or modify your cookie choices at any time by clearing your browser cookies for this domain or adjusting your browser settings.
5. Third-Party Advertising & Google AdSense Compliance
