Privacy Policy

Last updated: 2026-09-26

ToolDune is built to need as little of your data as possible. This policy explains what that means in practice.

Tool inputs never leave your browser

Every tool on this site — calculators, converters, counters, generators — runs entirely in your browser with JavaScript. The text, numbers and files you enter into a tool are processed on your device and are never transmitted to us, logged, or stored.

Cookies and advertising

This site currently runs no third-party advertising. If that changes, this policy will describe exactly what is used before it goes live.

Analytics

We use Google Analytics 4 with IP anonymization to count page views in aggregate. We never see individual browsing histories.

Local storage

The only thing we keep in your browser is one preference: your light or dark theme choice, saved via local storage when you use the theme toggle in the header. It never leaves your device and you can clear it anytime from your browser settings. We set no cookies of our own.

Changes

If this policy changes, the updated date at the top will change with it.
