Privacy Policy

1. Information we collect

Yutnori (yut.publicutil.com, the "Service") has no sign-up or login and does not collect personal information such as your name, email or phone number. Your game records are not sent to the operator's servers either. The only thing recorded on the operator's server is the visit count (a number), described in section 4.

2. Information stored on your device

To let you pick up your game easily, the following is stored only in your browser's storage (localStorage). It stays on your device and is not sent to the operator.

• Win records (total wins and streaks) and rulebook progress
• Customization choices (character skin and board theme)
• Settings (AI difficulty, rule of the day, character dialogue, sound effects)
• Your language choice (System default, Korean or English)
• A game in progress (one, for "Continue")
• The date of your last visit, used to count visits only once a day

3. Deleting stored information

Press Customize → "Reset records" in the game to erase game records and settings, or delete this site's data in your browser settings to erase all of the above.

4. Visit counts, cookies and ads

To show today's and total visits on the home screen, on your first visit of the day the Service tells the operator's visit counter (counter.publicutil.com) "one Yutnori visit". The server stores only the service name, the date (Korea time) and the visit count — nothing that could identify you, such as an IP address or browser details. Visits by search engine robots are not counted.

The Service uses no cookies, no external analytics tools (such as Google Analytics) and no ads. However, the hosting service that provides the site and the visit counter (Cloudflare) may process access logs (such as IP addresses) for operation and security.

5. Changes to this policy

If this policy changes, we will post the changes and the effective date on this page. If we ever introduce cookies, analytics or ads, we will update this policy before using them.
