Privacy Policy

1. Introduction

This Privacy Policy describes how Bitumen Calculator ("we", "us", or "our"), operated by BigTechies, collects, uses, and protects information about you when you use our website and services. We are committed to protecting your privacy and being transparent about our data practices.

Last updated: 11 June 2026.

2. Information We Collect

We collect two types of information:

2.1 Information You Provide Voluntarily

• Contact form submissions: When you use our contact form, we collect your name, email address, and message content. This information is used solely to respond to your enquiry.
• Calculator inputs: Your project dimensions and calculator inputs are processed entirely within your browser. They are not transmitted to or stored on our servers.

2.2 Information Collected Automatically

• Server logs: Like most websites, our hosting provider automatically records standard server log information, including your IP address, browser type, the page you requested, and the date/time of your visit. This data is used for security and operational purposes.
• Analytics data: We may use privacy-respecting analytics tools to understand aggregate usage patterns — for example, which calculators are used most and from which countries. This data is anonymised and cannot be used to identify you personally.
• Cookies and advertising identifiers: We use essential cookies for basic functionality. Google AdSense and related Google advertising services may use cookies, device identifiers, and similar technologies to serve, measure, and improve ads.

3. How We Use Your Information

We use the information we collect to:

• Respond to your contact form enquiries
• Operate, maintain, and improve the Service
• Monitor for and prevent security issues or abuse
• Understand aggregate usage patterns to prioritise new features
• Comply with legal obligations

We do not use your information to:

• Build personal profiles or track individual behaviour
• Send unsolicited marketing emails
• Sell or share your data with third parties for commercial purposes
• Sell your personal information

4. Cookies

Cookies are small text files stored on your device by your browser. We use the following types of cookies:

• Essential cookies: Required for the website to function correctly. You cannot opt out of these without disabling the site.
• Analytics cookies: Anonymous, aggregated data about how visitors use the site. You may opt out by using your browser's cookie blocking settings or a browser extension.
• Advertising cookies: Google AdSense may use cookies such as the DoubleClick cookie to help serve ads, limit repetition, measure performance, and support fraud prevention.

We do not control third-party advertising cookies directly. You can manage cookies in your browser settings and review Google ad personalization controls at Google Ad Settings.

We use Google AdSense advertising. Google and its partners may use cookies or similar technologies to serve contextual or personalized ads, measure ad performance, prevent fraud, and comply with advertising policies. Learn more from Google advertising technologies.

5. Data Storage & Security

Contact form submissions are stored on secure servers with industry-standard security measures including encryption in transit (HTTPS/TLS). We retain contact enquiries for up to 12 months to allow for follow-up, after which they are deleted.

Calculator inputs are never transmitted to our servers and are not stored anywhere beyond your browser session.

Despite our best efforts, no method of transmission over the Internet is 100% secure. We cannot guarantee absolute security.

6. Third-Party Services

We may use the following third-party services, each with their own privacy policies:

• Web hosting provider: Stores and serves website files. May retain server access logs.
• Analytics provider (if applicable): Receives anonymised usage data only. No personally identifiable information is shared.
• Advertising providers: Google AdSense and related Google advertising services may use cookies, web beacons, and similar technologies to serve and measure ads. These providers have their own privacy policies.

7. Your Rights

Depending on your location, you may have the following rights regarding your personal data:

• Access: Request a copy of the personal data we hold about you
• Correction: Request correction of inaccurate data
• Deletion: Request deletion of your personal data
• Restriction: Request restriction of processing of your data
• Objection: Object to processing of your personal data
• Portability: Request transfer of your data in a machine-readable format

To exercise any of these rights, please contact us or email info@bitumencalc.com. We will respond within 30 days.

8. Children's Privacy

The Service is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.

9. International Visitors

Bitumen Calculator is accessible worldwide. If you are accessing the Service from outside the country where our servers are located, your information may be transferred across international borders. By using the Service, you consent to such transfers.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The updated date at the top of this page will always reflect the most recent version. We encourage you to review this policy periodically. Continued use of the Service after changes constitutes acceptance of the updated policy.
