4. Server Logs & Anonymous Web Analytics

Like virtually all standard web servers, our hosting infrastructure may record basic technical request information when you load a web page. This includes:

• Your internet protocol (IP) address
• Browser type, device classification, and operating system
• Referring URLs, pages visited, and timestamps

These technical logs are used solely for diagnosing network performance, detecting distributed denial-of-service (DDoS) traffic, and optimizing page load speeds. They are not linked to identifiable individuals.

5. Third-Party Services & External Links

Our guides and calculators may contain informational links to trusted technical standards organizations, such as ASTM International, AASHTO, state Departments of Transportation (DOT), and the National Stone, Sand & Gravel Association (NSSGA).

We have no control over the privacy practices of external websites. When you click an outbound link to an external resource, we encourage you to review that third party's privacy policy.

6. European Economic Area (EEA), UK & Swiss Privacy (GDPR & Consent Framework)

For users residing within the European Economic Area (EEA), the United Kingdom, or Switzerland:
