Privacy policy

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

We do not set advertising or tracking cookies. If analytics are added in future, this page will say so before they are switched on, and they will be limited to aggregate page views.

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