Privacy notice

1. Information stored on your device

Your best scores, completed desks, number of rounds, layout records, sound and graphics settings are stored in browser local storage. These saved records are not uploaded to an operator database. Delete them in Choose desk → Delete my records, or clear this site's browser data.

2. Optional analytics

We use Google Analytics 4 after you select Allow analytics. Events can include page visits, starting and finishing a game, scores, sharing button use and visits through challenge links. They help us understand and improve the game. We do not send names, email addresses or friend lists in analytics events.

Google LLC may process cookies, device and connection information on servers outside your country. If you decline, we do not load the analytics script. You can change your choice using Privacy choices in the footer, or Analytics choice in Choose desk. Withdrawing permission stops subsequent analytics from the site; you can delete existing cookies through your browser's site-data settings. See Google's privacy policy.

3. Sharing a challenge

Challenge links contain a layout identifier and score, not your name or contact details. Anyone receiving a link can read that layout and score. Result images are generated in your browser and downloaded to your device.

Your device's share sheet and the Facebook, WhatsApp and X links open the sharing service you select. The KakaoTalk button loads Kakao's JavaScript SDK on demand. You choose the recipient or posting destination yourself. We do not collect your social passwords, friend lists, private chats or selected recipients. Each platform's own privacy policy applies when you use its sharing service.

4. Advertising and site delivery

Advertising scripts are currently disabled. An AdSense account or site review does not mean that ads have been approved. We will update the notice and applicable consent settings when advertising is activated.

Cloudflare delivers the site and may process IP addresses and connection logs for delivery, security and troubleshooting. We do not create member accounts or a separate database of personal browsing histories. See Cloudflare's privacy policy.

5. Contact and changes

If you email us, your email address and message reach the operator so we can reply. We use them to address your inquiry and delete them on request unless retention is required by law. You do not need to include sensitive personal information.

Privacy contact and deletion requests: Seongjin Shin (신성진), sjshin@cdsa.kr.
