Yuzu Springs IdleYuzu Springs Idle privacy policy
Last updated 28 October 2026
In short: Yuzu Springs Idle works without sending anything about you anywhere. The itch.io copy only asks itch.io for the newest version number. It only sends something if you join the leaderboards. Then it sends your name there (a made-up one the game picked for you, or your Discord username if you choose), three totals and the coins you have. You can leave at any time.

In the game
The same policy is in the game: in Settings → More → Privacy, and behind Privacy on the Leaderboards' Join card.
Who we are
Yuzu Springs Idle is made by Sullifish. For anything about this policy or your data, email SullifishStudios@outlook.com.
What stays on your computer
Your spring, your settings and your answer to "What are you up to today?" are saved only on your computer, in your Windows user folder (for the itch.io version, in AppData\LocalLow\Sullifish\Yuzu Springs). None of it leaves your computer. Deleting that folder removes it, and uninstalling the Microsoft Store version removes it too.
The game has no ads, no analytics and no crash reporting. It never reads your other windows, files or what you are working on.
Updates
As it opens, the itch.io copy of the game asks itch.io for the number of the newest version, so it can tell you when an update is out. If you sign in to itch.io in the game (Connect itch.io, or Sign in on the update message), it also asks itch.io which builds of the game your account can download, and downloads the newest one, so the game updates itself. The sign-in's key is kept in the game's folder in your Windows user folder and only ever sent to itch.io. Nothing about your spring goes with any of this; like any internet connection, itch.io sees your IP address. The Microsoft Store copy doesn't ask: the Store updates it.
If you join the leaderboards
The leaderboards are off until you choose Join: in the Guestbook, or when the game asks you once, a few minutes in. If you join, the game sends:
- your name on the boards: the made-up name the game picked for you, such as "Sleepy Otter 4127", or your Discord username if you choose Discord name (below). You never type a name.
- three totals: coins earned, guests welcomed, and time the spring has been open. Our check (below) works out this week's from them.
- the coins your spring has at that moment, so our check can tell a real spring from an edited save.
- the number of your weekly league (1, 2, 3 and so on), which the game works out from your all-time place, so it can show you the players you race that week.
- an anonymous player ID. Unity's sign-in service makes this ID when you join. It isn't linked to your name, email or any account.
Like any internet connection, it also shows your IP address to the service it connects to.
All players can see the names, places and scores on the boards. Nobody else sees the player ID.
We use this only to show the leaderboards and keep them fair. The legal basis is your consent: you choose Join, and pressing Leave stops all sending at once.
Keeping the boards fair
Players can't write to the boards themselves. Each time the game sends your totals, a small check of ours on Unity's servers compares them with your last ones and the time since, and only puts them on the boards if a spring could really have grown that fast. To do that, it keeps your last few totals, when they came, where this week started, your Discord username if you linked it, and the totals and coins of the last few sends it found impossible. Only the server can read this, not other players or the game. If your totals grow faster than any spring can, or your spring has more coins than it could have earned (a changed save or game), your scores are set to 0 on every board, the game starts that spring again from one wooden tub, and the Yuzu Springs Idle Discord server removes that player's rank. The new spring goes on the boards as it grows.
If you use your Discord name
Only if you press Discord name in the Guestbook: Discord's own sign-in opens in your browser and asks your OK to share your account's basic details with the game (Discord calls this "identify"). The game passes the access Discord gives it to our check on Unity's servers, which asks Discord for your username, so nobody can use someone else's, then the game gives the access straight back to Discord. Only the username is kept, as your name on the boards in place of the made-up one. It is first checked for rude words, and one that fails isn't used. Your scores then carry a note that the name is a Discord username, so the Yuzu Springs Idle Discord server can give you a rank role (Common to Ungodly) for your all-time coins earned. Once linked, it stays your name on the boards: Leave stops sending your scores, and an email to us removes those already sent. Discord's privacy policy: discord.com/privacy.
Who handles it
The leaderboards and our check run on Unity Gaming Services from Unity Technologies (Authentication, Leaderboards, Cloud Code, which runs the check, and Cloud Save, which keeps what it needs). Unity stores this data for us and may process it outside the UK, including in the United States. Unity's own privacy policy explains how they look after it: unity.com/legal/privacy-policy. We don't sell or share it with anyone else.
Buying a theme
The themes are supporter packs. In the Microsoft Store copy, Microsoft takes the payment, and the game asks the Microsoft Store which themes you own. In the itch.io copy, itch.io takes the payment. If you choose to connect your itch.io account in the game's Themes panel, itch.io's own sign-in opens in your browser, and with your OK itch.io gives the game a key that can only ask whether you own each Yuzu Springs Idle theme. The key stays on your computer, beside your save, and the game asks itch.io nothing else. Disconnect any time in the Themes panel, or remove the game from the connected apps in your itch.io settings. A theme added from its file sends nothing at all.
How long it is kept
Your scores stay on the boards until you ask us to remove them, or until the boards close. The weekly boards start fresh every Monday. Unity keeps past weeks as archives, which the game doesn't show. Pressing Leave stops new scores. Scores already sent stay until you ask.
Removing your scores
Email SullifishStudios@outlook.com with the name shown in the game. We remove your scores from every board, and what our check kept, within one month. Press Leave first, or the game sends your totals again when they change.
Children
The leaderboards are for players 13 and over, and the game says so before you join. Players under 13 can enjoy everything else, which sends nothing. If you think a child under 13 has joined, email us and we will remove their scores.
Your rights
Under UK data protection law, you can ask to see, correct or delete the data we hold about you, and you can object to its use. Email us. You can also complain to the Information Commissioner's Office at ico.org.uk.
Changes
If this policy changes, the date at the top changes too. A change that sends anything new will ask you first in the game.
