Privacy policy

How guest sessions, room chat, browser storage, visit analytics and anonymous game totals are processed and retained.

Join a game

No account is required, and real names, email addresses and passwords are not collected as a condition of playing. Online play uses a random guest ID and nickname. An authentication HttpOnly cookie lasts up to 24 hours. IP addresses are processed for security and rate limits, not stored in our game totals.

Game chat

Nicknames, moves and the latest 100 room messages are held in server memory. Public listings show nicknames and room status. Waiting rooms expire after 30 minutes; finished rooms after one hour. Games stop without a result after four hours. Restarting the server clears online records.

Play AI

The current AI game, the latest ten completed AI games and preferences are stored only in this browser. They are not uploaded to the game server. Delete this site's browser data to remove them. Records do not sync across devices.

Analytics preferences for this browser

Our server stores daily totals for AI starts and finishes, room creation and joining, matches and connection errors for up to 90 days. It stores no individual visit histories, nicknames, chats, IPs, cookies, search terms, invite codes or full URLs in that file. Development, automation and excluded browsers are omitted.

Naver Analytics

Naver Analytics is used on public information and AI pages. Naver processes page address and title, referral source, browser, device, screen, IP and visit identifiers in cookies or browser storage. Its standard script synchronizes visit identifiers. It is disabled on online lobbies and rooms, errors, query/hash URLs and visits from sensitive paths. We do not send chat, nicknames, authentication cookies, invite codes or game contents. Reports therefore do not count every site connection.

Exclude this browser from analytics

Our 90-day limit does not apply to Naver's data, which follows Naver's own privacy and analytics policies at policy.naver.com/policy/privacy.html. Use the browser exclusion control below or browser tracking protection. Do Not Track, test automation and development are excluded. Opting out does not retroactively delete data already processed. Search terms are available only as aggregated reports from Google, Naver and Bing; we cannot identify every visitor's query.

AWS · Cloudflare

The game server and daily totals are hosted on AWS in Seoul. Cloudflare's global network processes IP and request data for HTTPS, DNS and attack protection. Its Free dashboard provides recent security events for 24 hours and analytics for seven days; these are viewing windows, not a statement of all provider retention. Normal access logs are disabled. Diagnostic logs may contain IPs or paths and are kept up to seven days or a size limit. Private backups of configuration and totals are retained in Seoul for seven days; guest authentication, rooms and chat are not backed up.

Contact

The service operator can be contacted at [email protected] for access, deletion and privacy questions. Mail is forwarded by Cloudflare Email Routing to the operator's Gmail, so Cloudflare and Google process the sender address and message. The operator deletes resolved inquiries within 90 days. Providers may use global infrastructure under their policies. Browser data can be deleted locally; anonymous daily totals cannot be separated by person. Effective date: 3 October 2026.

Spoken results

When sound is on, the browser speech engine reads win, loss or draw. Voice availability and pronunciation vary by device. If the browser uses a remote voice, only the fixed result phrase is processed by that voice service. Nicknames, chat, room codes and game history are never passed to the speech engine. Use the sound button to turn it off.

Analytics preferences for this browser

Exclude operator, developer and test browsers. This controls Naver visits and our game totals without affecting play. Changing it reloads this page; also reload other open tabs.
