Privacy Policy

1. Introduction

At Asphalt Calculator (accessible via asphaltcalculatorai.com), your privacy is of paramount importance. This Privacy Policy details what information is collected, how it is used, and how your data is protected when you use our paving estimation tools and website services.

2. Information We Collect

Local Calculator Inputs: All calculations performed on this utility—such as driveway length, width, thickness, compaction factors, and unit costs—are executed exclusively in your web browser via client-side JavaScript. We do not transmit, log, store, or sell your calculation parameters on our servers.

Technical Server Logs: Like most modern web utilities, our hosting provider and content delivery network (Cloudflare) automatically collect standard technical access logs, including your anonymized IP address, browser type, operating system, referring URL, and access timestamps. This information is utilized solely for DDoS protection, site stability, and security diagnostics.

Voluntary Inquiries: If you contact us via our contact form or support email, we collect only the information you choose to provide (such as your name, email address, and message) strictly to respond to your support request.

3. Cookies & Analytics Technologies

We do not deploy intrusive tracking cookies or sell marketing profiles. We may utilize standard aggregate analytics tools (such as Google Analytics 4) to monitor general site performance, popular screen resolutions, and traffic volumes. All collected analytics data is anonymized and aggregated. You can adjust your browser settings to refuse cookies or delete existing cookies at any time without impacting any calculation features.

Theme Preference Storage: We use your browser's local storage (localStorage) solely to remember your chosen display theme (light mode or dark mode) across browser visits.

4. Third-Party Infrastructure

Our web services are delivered through reputable global cloud infrastructure providers, including Cloudflare Pages. These enterprise providers adhere to strict international privacy protocols (including SOC 2 and ISO 27001 certifications) and process web requests securely on our behalf.

5. Your Data Protection Rights (GDPR & CCPA)

Depending on your jurisdiction, you possess specific legal rights under applicable privacy legislation, such as the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA):

• The right to request disclosure of personal data retained about you
• The right to request prompt deletion or rectification of your information
• The right to opt out of the sale or sharing of personal data (we do not sell personal data)
• The right to non-discrimination for exercising your legal privacy rights

6. Children's Online Privacy Protection

Asphalt Calculator is an engineering and home-improvement utility designed for adult homeowners, DIYers, and commercial contractors. We do not knowingly solicit or collect personally identifiable information from children under the age of 13.

7. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect enhancements to our tool or statutory compliance updates. The effective revision date will always be prominently noted at the top of this document. Continued use of the website following any update signifies your acceptance.
