FinanceTools

Privacy Policy

Your privacy matters. This page explains exactly what FinanceTools collects, what we don't, and how third-party advertising works.

Last updated: May 18, 2026

The Short Version

We don't ask for your name, email, or any personal information to use this site. All calculations happen in your browser — we never see the numbers you enter. We do show ads through Google AdSense, which uses cookies. The rest of this page goes into the details.

What Information We Collect

Calculator inputs: Nothing. Values you type into any tool are processed entirely in your browser and are never transmitted anywhere.

Server logs: Like most websites, our hosting provider automatically logs basic technical data — IP address, browser type, the page you visited, and the date and time of the request. This is standard infrastructure logging and is not linked to any individual.

Cookies from us: None. FinanceTools does not set any first-party cookies.

Advertising & Cookies

We use Google AdSense to display advertisements on this site. AdSense is a third-party advertising service operated by Google LLC. To serve relevant ads, Google uses cookies — including the DoubleClick cookie — that track your browsing activity on this site and others you've visited.

Google's advertising cookies collect information such as the pages you visit and the links you click, but they don't collect your name, address, email address, or phone number.

You have two main options for controlling this:

Third-Party Services

Beyond AdSense, this site uses Google Fonts (Geist Sans, Geist Mono) delivered through Next.js's font optimisation system. Google may process your IP address as part of serving these font files. See Google's Privacy Policy for details.

No other third-party scripts, analytics platforms, or tracking tools are loaded on this site.

External Links

Some pages on FinanceTools link to external websites — for example, NHLBI.gov for BMI reference data. Once you leave our site, this Privacy Policy no longer applies. We recommend reading the privacy policy of any external site you visit.

Children

This site is not directed at children under 13. We don't knowingly collect any information from children. If you believe a child has submitted personal information through our site, please contact us and we'll handle it promptly.

Changes to This Policy

We may update this page occasionally. When we do, the "last updated" date at the top will change. We won't send notifications for minor wording changes, but if anything significant changes about how data is handled we'll make that clear. Continuing to use the site after a change means you accept the updated policy.

Contact

If you have any questions about this Privacy Policy, email us at hello@online.com. We typically respond within 2 business days.
