Privacy Policy

The short version
This website has no user accounts, no comment system, and sets no tracking cookies. Our tools and calculators run entirely in your browser; the values you type into them are not transmitted to us.
What is technically processed
Like any website, our hosting infrastructure processes standard server logs (such as IP address, user agent and requested URL) for security and operations. These are handled by the hosting provider under their own terms.
If you contact us by email, we receive what you send and use it only to respond and to act on the content of your message (for example, a correction). We do not add you to lists or share your address.
Newsletter
If a newsletter signup is offered, subscribing is optional, the address is used only for the newsletter, and every issue includes an unsubscribe link.
Changes
Material changes to this policy will be reflected on this page with a new updated date.
