Last updated: July 2025
BitumenCalculator.world is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights. Our calculators are free to use and require no personal information.
Information We Collect
BitumenCalculator.world does not require account registration or sign-up. We do not collect personal information such as your name, email address, or payment details. All calculations are performed entirely in your browser — no calculation data is transmitted to our servers.
Analytics
We may use privacy-respecting analytics tools to understand aggregate traffic patterns (e.g. page views, country of origin). This data is anonymised and cannot be used to identify individual users. We do not sell or share this data with third parties.
Cookies
This website does not use tracking cookies or advertising cookies. We may use a single session cookie to support basic site functionality (e.g. unit preference). You can disable cookies in your browser settings without affecting the core calculator functionality.
Third-Party Services
This website may be hosted on a third-party infrastructure provider (e.g. Vercel). Their privacy policy applies to data processed at the hosting layer. We do not use third-party advertising networks or cross-site tracking scripts.
Children
This website is a professional engineering tool. We do not knowingly collect any information from children under 13 years of age.
Changes to This Policy
We may update this privacy policy occasionally. Changes will be posted on this page with an updated date. Continued use of the site after any changes constitutes acceptance of the updated policy.
