Privacy Policy

Last updated: October 31, 2026

This Privacy Policy explains what information Cosmillion (“we”, “us”) collects when you use www.cosmillion.org (the “Site”). In short: we don’t collect personal data.

1. Information we collect

We do not ask you to create an account, and we do not collect your name, email address or any other personal information while you play.

2. Data stored on your device

Your last 50 completed games (date, answers and score) are saved in your browser’s local storage so you can see them in the Logbook. This data stays on your device and is never sent to us. You can delete it at any time by clearing your browser’s site data.

3. Cookies and tracking

The Site does not use cookies, analytics or advertising trackers.

4. Server logs

Like most websites, our hosting provider may automatically record basic technical information (such as IP address, browser type and the pages requested) for security and performance. We do not use this information to identify you.

5. Share buttons

When you click a share button (X, Facebook, WhatsApp, Reddit), you are taken to that service, and its own privacy policy applies. Nothing is sent to those services unless you click.

6. Children

The Site is suitable for all ages and does not knowingly collect information from children.

7. Changes to this policy

We may update this policy from time to time. Changes take effect when posted on this page.

8. Contact
