Privacy

Numbaru works in your browser. The numbers you generate and the numbers you mark on a slip are never sent to a server. The site is run by IVEL.

What is stored on your device

When you mark numbers on a slip, the marks are saved in your browser's local storage so they are still there when you come back. You can remove them with "Clear marks" or by clearing your browser data.

What we collect

We do not ask for an account, a name or an email address. The web host keeps standard server logs (IP address, browser type, page requested) for security and to keep the site running. If you write to [email protected], we keep your message and address to answer you.

Visit counts and the most viewed pages are measured with Cloudflare Web Analytics, which uses no cookies and does not identify you.
