Ukiyo Duels Privacy Policy

Last updated: 26 October 2026

Ukiyo Duels is made by Kitchen Labs. It's a card duel game you play in your browser, against other players or the computer. This page says, in plain English, what happens to your information.

The short version

You play as a guest straight away. There's no password, and an email address is only needed if you choose to save your progress to one.
Your name, cards and progress are kept on our database so they're there next time.
Other players see the name you pick. Friends you accept can watch your duels.
When no other player is free, your opponent may be played by the computer: ordinary game code on our server. No AI service is used, and nothing you do is sent to one.
There are no ads and no analytics or tracking code. Nothing can be bought with real money.
You can delete your account yourself in Settings.

What we handle, and why

A guest account. The first time you open the game, it signs in to Kitchen Labs' database (hosted by Supabase) with a random anonymous ID. Nothing links that ID to your real name, email or phone. We make a player for it with a starting name like "Wanderer 417", which you can change in Settings (up to 24 characters). The same sign-in system is shared by Kitchen Labs' other apps.

Your email, only if you add one. In Settings → Save your progress you can add an email so you can get your player back on another device or after clearing your browser. We send a link to that address to confirm it, and later to sign you in. The email is kept with your sign-in and is used for nothing else: no newsletters, no marketing.

Your progress. To run the game we keep, linked to your anonymous ID: your name; your Coins, Pearls and Gold Leaf, with a record of what earned or spent each one; the cards you own and their levels; your saved hands; your place on the Road (Honor and the stations you've reached); your fortunes and what they held; the looks and items you've collected and are wearing; your daily and weekly tasks; your Festival Pass progress; your Pilgrimage runs; and the cards the daily shop offered you.

Duels. While you look for an opponent, a short entry (the mode, your Honor and your hand) waits in a queue and is removed once you're paired, or within minutes if you stop waiting. Each duel keeps a short record: the two players' names and how they looked, the mode, who won and what each side earned. The full turn-by-turn record, which is what lets you watch a replay, is deleted after 30 days. During a duel the game sends short live signals between the two players (that a move landed, and the Fan emotes you send); they hold no personal details. We also count, across all players and without names, how often each card is played and wins each day, to keep the game fair.

What other players see. Your opponent sees your name, your fighter and your hand during a duel. The leaderboard shows the top 100 players' names and Honor to everyone who plays. Once you reach Kyoto, your Road duels also give you a Court rating for the season, and the top 1,000 players' names, ratings and number of rated duels are shown the same way. Your friend code is a short code made from your anonymous ID; anyone you give it to can send you a friend request. Friends you accept see your name, your Honor and whether you're in a duel, and can watch your duels live and replay them while the turn-by-turn record is kept. You can remove a friend at any time.

Computer opponents. Practice is always against the computer, and an online duel can be too when no other player is free. That opponent is game code running on our server. No AI service is involved and nothing you do leaves our systems for one.

What stays on your device

Your browser keeps your sign-in (so you stay the same player), your sound, motion and camera choices, which "Learn to play" lessons you've finished, and which tips and notes you've already seen. These stay until you clear this site's data. If you haven't saved your progress to an email, clearing this site's data means losing access to your player.

What we don't do

No ads, no selling or sharing of data.
No analytics or tracking code is included in the game.
No AI service receives anything from the game.
Nothing can be bought with real money: there is no checkout, and we never ask for payment details. Random rewards are never sold, and their exact odds are listed on the game's Odds page.
Fonts are served from our own site, not from Google.

Deleting your information

Open Settings → Delete account and confirm. If you're in a duel, it ends and your opponent gets the win. Then your name, cards, hands, Coins, Pearls, Gold Leaf, Road, fortunes, tasks, Festival Pass, Pilgrimage runs, looks, friends and friend requests are deleted for good. Your sign-in, and the email on it if you added one, is deleted too, unless you also use another Kitchen Labs app with the same sign-in.

The short records of duels you've already played stay so your opponents' histories make sense. They keep the name you played under and a random ID that no longer leads to an account; their turn-by-turn records are deleted 30 days after the duel, like everyone's.

If you can't get into the game to delete your account, contact us with the name you played under.

Children

Ukiyo Duels isn't meant for children under 13.
