Privacy policy

Smetalo does not require registration. The numbers you enter in the calculators are not sent anywhere: all calculations run in your browser.

Your browser only remembers your chosen theme (light or dark) and, for the current tab, the scroll position of the calculator list.

When you send a message through the feedback page, we receive only what you wrote in the form. The message is forwarded to our mailbox through the Web3Forms service. Your email is optional and used only to reply to you.

The site is hosted by Cloudflare and the fonts are loaded from Google Fonts. As with any website, these providers receive technical connection data, such as your IP address, to deliver the page.
