Privacy
Your numbers stay yours.
IFN Tools is built to answer your question and forget you asked. This page explains what we collect (very little), what we don't, and how advertising works here.
The short version
Every calculation happens locally in your browser. We have no accounts, no logins, and no server-side profiles. We cannot see the numbers you type into a calculator, and we don't want to.
What we do collect
We use Cloudflare Web Analytics to understand aggregate traffic — roughly how many people visit, which tools get used, and which countries visits come from. It does not use cookies, does not track you across websites, and does not identify you personally.
Cookies
The site itself sets no cookies. If we display advertising in the future, our advertising partners (such as Google) may use cookies to serve and measure ads. You can control cookies through your browser settings at any time.
Advertising
IFN Tools is free, supported by advertising and occasional affiliate links. Advertising partners may collect data as described in their own privacy policies. A calculator page will never sell you something you didn't come for, and we don't share personal data with advertisers because we don't collect it.
Children
IFN Tools is a general-audience site and does not knowingly collect information from children under 13.
Changes
If this policy changes in a meaningful way, we will update this page and note the revision date below.
