Privacy policy

We don't ask you to create an account and we don't collect your name, email or address. The calculators run entirely in your browser; nothing you type is sent to us.

Hosting and basic logs

The site is served by Cloudflare, which processes basic technical data (such as IP address and browser type) to deliver pages and protect the site.

Affiliate links

When you click a link to a seller, that seller (or its affiliate network) may set a cookie to record that you came from us. Their privacy policies apply on their sites.

Analytics

We count page views and clicks on the "Check price" buttons so we know which guides help. Each count records only the page, the button, the kind of site that sent you (for example Google), your country and whether you're on a phone or a computer. We don't use cookies for this and we don't store IP addresses or anything else that identifies you. To credit a visit's starting point, your browser tab keeps a short note of where you came from until you close the tab.
