The short version

The tools run in your browser. What you type, including birth dates and loan amounts, is not sent to us. We use no cookies, no analytics and no advertising trackers today.

What is stored on your device

• localStorage: your screen calibration, unit preference (metric/imperial), ruler orientation and, if you open “Privacy choices”, your consent settings.
• Offline cache: a service worker stores pages and files so the tools work without a connection.

You can delete all of this at any time in your browser settings (site data for this domain).

Shareable links

When you use a calculator, the values appear in the page address so you can bookmark or share the result. They stay in your browser unless you share the link yourself.

Server logs

Our hosting provider may process standard technical data such as IP address and browser type to deliver pages and protect against abuse. We do not use it to identify or profile you.

If this changes

If we add advertising or analytics, we will update this page first, name every provider, and ask for consent where the law requires it (for example in the EU and UK) before anything loads. You will be able to change your choice at any time from the “Privacy choices” link in the footer.

Your rights

Under the GDPR and similar laws you can ask to access, correct or delete personal data. Because we do not hold personal data about visitors, there is usually nothing to retrieve, but you are welcome to write to us.
