Privacy

We collect as little as we can.

Newsletter

If you subscribe, we keep your email address, the date you signed up, the page you signed up on and your country (worked out from your connection, not your exact location). We use it only to send you the newsletter. We do not sell or share your address. Every email has an unsubscribe link, and you can ask us to delete your address at any time by replying to any newsletter.

Visiting the site

The site does not use advertising or tracking cookies. Our hosting provider, Cloudflare, processes basic technical data (such as your IP address) to deliver the pages and protect the site from abuse.

Free tools

Our calculators and invoice generator run entirely in your browser. What you type is saved only on your own device (in your browser's local storage) so it is there next time; it is never sent to us. You can clear it at any time.

Links to other sites

When you follow a link to a tool's website, that site's own privacy policy applies. Some links may tell the tool's company that you came from us, so a commission can be credited; see how we earn.
