Privacy policy

The tools on this site run entirely in your browser. The numbers you type are never transmitted, stored or logged.

We use Google Analytics 4 to count page views and see which tools get used. It sets a first-party cookie (_ga) and sends aggregate usage data to Google. It is not used to identify you, and the numbers you type into the tools are never sent to it. You can block it with any content blocker or Google's Analytics opt-out add-on — every tool keeps working without it.

If advertising is added later, this page will be updated before any ad code goes live.

Server logs from our hosting provider may record standard request information (IP address, user agent, requested URL) for security and abuse prevention.
