What we collect
The calculators run entirely in your browser. The measurements, prices and other numbers you type are not sent to us or stored.
Analytics
We use Google Analytics to understand how many people visit, which pages they read and roughly where they come from, so we can improve the site. Google Analytics uses cookies and collects information such as your browser type, device, approximate location derived from your IP address, the pages you view and how long you stay. We don’t use it to identify you personally.
Google processes this data under its own privacy policy. You can opt out of Google Analytics on all websites with Google’s browser add-on, or by blocking cookies in your browser.
Advertising
The site doesn’t currently show ads. If that changes, this policy will be updated to describe the advertising partners and cookies involved before ads appear.
If you email us, we receive your email address and whatever you write. We use it only to reply and don’t share it or add you to a mailing list.
Children
The site is a general-audience tool and isn’t directed at children under 13. We don’t knowingly collect personal information from children.
Your choices
You can browse the site with cookies blocked; the calculators will still work. If you’d like us to delete an email conversation, write to hello@sodcalculators.com.
Changes
We’ll update this page if our practices change, and change the date at the top.
