Privacy

We don't ask for your name or any account. Calculators and tools on this site run in your browser: what you type into them is not sent to us.

Analytics and cookies

We count visits with Cloudflare Web Analytics, which uses no cookies and doesn't track you across sites.

Videos

Some pages show one of our short videos from YouTube. Nothing loads from YouTube until you press play: before that you see a still picture, which may come from YouTube's image server (i.ytimg.com, no cookies). Pressing play loads YouTube's privacy-enhanced player (youtube-nocookie.com) on the page, and YouTube's privacy policy covers what it does from then on.

Affiliate links

When you follow an affiliate link, the seller may set its own cookie to record that you came from us. Their privacy policy applies on their site.

Your sound settings

The sound mixer remembers where you left each slider for each place. That's kept in your own browser (local storage), never sent to us, and clearing your browser's site data removes it.
