Privacy policy

The short version: what you type into our calculators stays in your browser. We never see your income, savings, debts or any other number you enter.

Calculator inputs

Every calculation runs on your own device. Your inputs are not sent to us or to anyone else, and we do not ask for an account, name or email.

Analytics

We use Google Analytics to count visits and see which pages and tools get used. It records things like the pages you view, your device and browser, your approximate location (city or region) and whether you started using a calculator. Google sets cookies to tell repeat visits apart. In the EU, UK and Switzerland, analytics cookies stay off.

You can block analytics with your browser settings, a content blocker, or Google's opt-out add-on.

Outside services

Pages load fonts from Google Fonts. Car calculators may load photos and short descriptions from Wikipedia. Those services receive your IP address when your browser requests them.

Changes

If we add advertising or affiliate links, we will update this page first. Last updated October 28, 2026.
