Privacy Policy
Last updated October 2, 2026
This policy explains what information BuildKit handles when you use this website.
Your calculator inputs
Calculations are performed in your browser. The measurements and options you enter are not sent to our servers and are not stored after you leave the page.
Information collected automatically
Like most websites, our hosting provider may log technical data such as IP address, browser type, pages requested and timestamps. This is used to keep the site secure and working.
Advertising
BuildKit is free and may show advertisements served by third parties, including Adsterra. These providers may use cookies or similar technologies to show ads and measure their performance, and may collect information such as your IP address and device details. See the Adsterra privacy policy for details. You can block or delete cookies in your browser settings, or use your browser's privacy controls and ad settings.
Analytics
We may use privacy-conscious analytics to see which pages are used and to improve the calculators. If we do, it measures aggregate usage, not your calculator inputs.
Cookies
BuildKit itself does not require cookies to work. Cookies may be set by advertising or analytics providers as described above.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.
Your rights
Depending on where you live, you may have rights to access, correct or delete personal data held about you. Because we do not collect personal data directly, most requests would need to go to the relevant third-party provider. Questions can be sent through our contact page.
Changes
We may update this policy from time to time. The date at the top shows when it was last changed.
