Privacy Policy

Arcade (arcade.zuz.kr) · Effective: 2026-10-28 · 한국어

1. Who we are

• Operator: cooctal (representative and privacy officer: 옥창훈, Ok Changhoon)
• Business registration number: 121-41-64681
• Address: 402, 140 Tojeong-ro, Seoul, Republic of Korea
• Contact: cooctal8@gmail.com

2. What we process and why

You do not need an account. We do not ask for your email or any contact details.

• Ranking entries (to run the public ranking): the name you type (optional, up to 12 characters — please do not use your real name or contact details), score, play time, game ID and the time the entry was saved. They are shown publicly in the ranking.
• Game sessions (to check that scores are real and to count each play once): a random session ID, game ID, a random number used to set up the game, and the times it was issued, used for a score, and counted as a play.
• Play counts: one anonymous total per game. It is not linked to you.
• IP address (to limit too many requests): used only for a moment while handling a request. We do not save it in our database.
• Request logs (to find errors): our hosting provider Cloudflare records each request handled by our server code (Workers Logs, turned on by us): the address and method of the request, the time, the result, and connection details Cloudflare adds, which may include your IP address. Requests for images and other files are not included.

3. How long we keep it

• Ranking entries: until the service ends or you ask us to delete them.
• Game sessions: deleted automatically by a daily job once they are 2 days old (so at most about 3 days).
• Request logs: deleted automatically by Cloudflare after 3 days.
• Play counts: until the service ends.

4. How we delete it

When the period ends or you ask, we delete the data from the database so it cannot be shown again. Cloudflare keeps database recovery points for 30 days, so deleted data disappears from them within 30 days. Database backups we make before maintenance are kept only on the operator’s access-controlled computer.

5. Service providers and transfer abroad

• Cloudflare, Inc. (USA; data centers worldwide) hosts the site, the database and the request logs. What: everything in section 2. When and how: sent over the network each time you use the site. Kept: as in section 3. Contact: privacyquestions@cloudflare.com.
• This is needed to provide the site. If you do not want it, please do not use the site; there is no other effect.
• Google ads are currently off. Before we turn them on, we will add Google LLC (USA) here and update this page.

6. Security

• All traffic is encrypted (HTTPS); plain HTTP addresses are sent to HTTPS.
• Only the operator can access the database and logs, through a protected Cloudflare account.
• We do not store IP addresses, emails or passwords. Inputs are checked and requests are rate-limited.

7. On your device and cookies

• Your best score for each game is kept in your browser (local storage) and is not sent to us. You can clear it in your browser settings.
• This site sets no cookies of its own today. You can refuse or delete cookies in your browser settings (for example, Chrome or Edge: Settings → Privacy → Cookies; Safari: Settings → Privacy). The games still work.

8. Ads

• The result screen has one small ad space. Ads are not shown on the start page or during a game.
• Today the space shows only a banner for our own service ZUZ. It uses no cookies or tracking.
• When Google ads (AdSense) are turned on: third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies lets it and its partners serve ads to you based on those visits. You can opt out of personalized advertising in Google Ads Settings. See also how Google uses information from sites that use its services. Users in the European Economic Area, the United Kingdom and Switzerland will be asked for consent before cookies are used for ads and can change their choice at any time. To avoid showing ads too often, your browser tab then also keeps the time of the last ad request (removed when you close the tab).

9. Your rights

• You can ask to see, correct, delete or stop the processing of your ranking entries. Email us the game, score, name and approximate date and time so we can find the entry. Someone you authorize can ask for you.
• We will answer within 10 days.
• For help with privacy complaints in Korea: Personal Information Infringement Report Center (privacy.kisa.or.kr, 118), Personal Information Dispute Mediation Committee (www.kopico.go.kr, 1833-6972).

10. Changes

If this policy changes, we will update this page and the effective date.
