You don't need an account to use Yastero, and your measurements stay in your browser.
Your project list
When you press Add to my list, the result is saved in your browser's local storage on this device. It is not sent to us. Clearing your browser data, or pressing Clear list, deletes it.
What we collect today
The site does not use accounts, forms or tracking cookies. Our hosting provider (Cloudflare) processes standard technical data, such as IP addresses, to deliver and protect the site.
Visit statistics
We use Cloudflare Web Analytics to count visits, so we know which calculators people use and which pages need work. It does not set cookies, does not use your browser's storage and does not follow you to other sites. We only see totals, such as page views, the site that sent you, your country and your type of device.
Changes
If we add advertising, this page will be updated before it goes live, including any consent options required where you live.
