Privacy
The calculators run entirely in your browser. The prices and costs you type are never sent to us.
What we collect
Our web server keeps standard access logs (IP address, page, browser) for security and is fronted by Cloudflare. We don't use accounts, and we don't sell data. Analytics never receive the numbers you type.
Analytics
We use Google Analytics to count visits and see which calculators are used, and Microsoft Clarity, only if you click Accept, to see where pages are confusing. Visitors in the EEA, UK and Switzerland get no analytics cookies unless they accept. You can change your choice by clearing this site's data in your browser.
Changes
If we add advertising, we'll update this page first and ask for consent where the law requires it.
