Privacy policy
Updated: October 14, 2026
Room data
We process nicknames, player colors, room codes, game settings, answers, custom topics, card effects and game results to operate rooms. These can be shared with other participants as the game progresses. Anonymous answers may later reveal their authors. Do not submit secrets or other people’s personal information.
Rooms end when everyone leaves or after 30 minutes without participation or game actions. Expired room records are removed by the room service. Game data is reset when starting a new game. We do not record voices.
Browser storage
Browser storage keeps your session token, nickname, recent room code and language preference. Seat Match drafts may be stored in session storage so you can resume them on the same browser. Clearing storage removes these local settings and may prevent reconnecting as the same player.
Japanese and English
Use the language buttons to change your own interface. Your choice is stored on this device. Without a saved choice, the browser’s preferred supported language is used. If neither Japanese nor English is identified, an approximate country code supplied by Cloudflare is used as a fallback (Japan: Japanese; otherwise: English). This is not GPS location and can be inaccurate, for example with a VPN.
The room language is fixed when the host creates it and applies to all players. Create a new room to play in another language. Player names, answers, custom topics and card effects are never automatically translated. English adaptations of built-in topics may use more general cultural references.
Service providers
Firebase Hosting delivers the site. Cloudflare Workers and Durable Objects run rooms and can provide an approximate country code for language fallback. These providers may process IP addresses and connection information for delivery and security. The application does not create an access analytics record from the country lookup.

Contact messages
The form sends your chosen category, message and reply email through FormSubmit to the operator’s Gmail inbox. FormSubmit states that it retains submissions for 30 days; this does not mean emails in our inbox are automatically deleted after 30 days. Its confirmation and spam-protection pages may use cookies. We use messages to respond and investigate issues, and retain them as needed for that purpose.

Analytics
Only with your consent, Google Analytics 4 uses cookies to measure visits, referrals, device information, approximate region and game starts. We do not send player names, answers, room codes or fortune-telling inputs. Analytics cookies expire after 90 days. Use Analytics settings at the bottom of the page to change or withdraw consent. Games work without consent. Starts count consenting hosts who start a game, not every play.
Advertising
This version does not load Google AdSense or H5 Games Ads serving scripts. Before enabling advertising, we will update this policy and implement any required notices and consent. Advertising providers may use cookies, web beacons and IP information for ad delivery, measurement and fraud prevention.
