Personal data

You don't need to register. The calculator runs entirely in your browser: the values you enter are never sent to a server. We only receive personal data if you write to us through the contact form: your name, email and message, used only to reply and deleted within 12 months of our last exchange. They are not shared with third parties or used for advertising.

Cookies

The site uses no advertising or analytics cookies. To count visits we use GoatCounter, a cookie-free analytics service that does not store IP addresses or identify visitors: it only records the page viewed, the referring site, the browser type, the screen size and the country. If advertising services (for example, Google AdSense) are used in the future, this page will be updated and your consent will be requested before any non-essential cookie is set, as required by the GDPR and Portuguese Law No. 41/2004.

Links to other sites

Some pages may contain links to stores or manufacturers. If any of them is an affiliate link, this will be stated next to the link.

Hosting

The hosting provider may log technical access data (IP address, date and page visited) for security and to keep the service running.
