Umamusume: Pretty Derby’s cross-platform support is powerful, but it’s also unforgiving if you rush it. The Steam version isn’t a separate ecosystem or a fresh-start client; it’s a mirror that can fully sync with your existing mobile account when linked correctly. Do it right, and you can bounce between phone and PC without losing a single Skill Hint, Support Card limit break, or hard-earned Champion Meeting trophy.
At its core, account linking in Umamusume is a one-to-one connection between a single Cygames account and one game save. There’s no manual save selection, no rollback, and no safety net if you overwrite data. Understanding how the system decides which data is “correct” is the difference between seamless cross-play and catastrophic progress loss.
One Account, One Save, Shared Everywhere
Umamusume does not support multiple save slots under one account. When you link your mobile account to Steam, both platforms pull from the same cloud-backed profile tied to your Cygames ID. All Trainers, Support Cards, jewels, story progress, and event states are shared in real time.
This means your Steam install is effectively another terminal logging into the same account. If you raise a horse on PC, that progress instantly exists on mobile the next time you log in, and vice versa. There’s no platform-exclusive progression or stat desync to manage.
The Role of the Cygames Account
The Cygames account is the backbone of cross-platform play. Linking does not happen directly between mobile and Steam; both versions independently authenticate to the same Cygames account. If your mobile data is not already linked to a Cygames account, it is functionally local-only and vulnerable.
This is where most data loss horror stories start. Launching Umamusume on Steam without first binding your mobile progress to a Cygames account can cause the Steam version to generate a fresh profile. If that new profile gets linked instead, your original data becomes inaccessible.
Steam Is Not a Fresh Start Button
When you first boot Umamusume on Steam, the game assumes you are either a brand-new player or a returning Trainer logging in via Cygames. There is no prompt asking which save you want to keep. The system simply trusts the account you authenticate with.
If you accidentally log in with a different Cygames account than the one tied to your mobile progress, Steam will treat it as a clean slate. Linking after the fact does not merge accounts, overwrite selectively, or recover progress. Whichever account is linked is final.
Platform Limitations Players Need to Know
Paid jewel balances are platform-restricted due to store policies. While your total jewel count carries over, purchased jewels may only be spendable on the platform where they were bought. This doesn’t affect free jewels, tickets, or gacha rates, but it does impact how you plan pulls across devices.
Event timing, banners, and gameplay systems are otherwise identical between mobile and Steam. There’s no gameplay advantage baked into PC, just higher resolution, smoother performance, and better multitasking for long育成 sessions.
Why Order of Operations Matters
The safe rule is simple: mobile first, Steam second. Your existing progress must be fully linked to a Cygames account on mobile before you ever attempt to log in on Steam. Once Steam is authenticated with that same account, synchronization is automatic.
Reversing that order is where players get burned. Umamusume doesn’t warn you before overwriting unused data, and customer support is notoriously limited when it comes to account recovery. Treat the linking process like a high-stakes gacha pull where RNG is replaced by precision.
Prerequisites Before Linking (Supported Regions, Accounts, and Versions)
Before you even touch the linking menu, you need to confirm that your setup is actually eligible. Umamusume’s account system is rigid, and mismatches in region, account type, or game version are the fastest way to trigger the exact data loss scenarios outlined above. Think of this as checking your build before entering a high-difficulty race: skip it, and you wipe.
Supported Regions and Server Alignment
Steam and mobile linking only works if both versions are on the same regional server. The global Steam release syncs with the global mobile version, while the Japanese Steam client is locked to JP mobile accounts. There is no cross-region migration, no server hopping, and no workaround using VPNs once an account is created.
If your mobile account was started on the JP version, you must use the JP Steam client and a Japanese Cygames account. Mixing global mobile with JP Steam, or vice versa, results in Steam generating a brand-new Trainer profile that cannot see your existing data.
Cygames Account Is Mandatory, Not Optional
Linking is done exclusively through a Cygames account. Guest accounts, device-only saves, or platform-based logins like Google Play or Apple ID do not sync directly with Steam. Your mobile progress must already be bound to a Cygames account before Steam ever enters the equation.
One Cygames account equals one Umamusume profile. You cannot merge multiple mobile saves, switch which Trainer is linked later, or undo a binding once Steam authenticates. This is a hard lock, not a soft preference.
Version Parity Between Mobile and Steam
Both the mobile app and the Steam client must be fully updated before linking. If your mobile version is behind due to a delayed store update or region mismatch, the linking menu may not appear or may fail silently. Steam auto-updates by default, so mobile is usually the weak point here.
Always launch the mobile app first, confirm it loads your correct Trainer data, and verify you can access the Cygames account settings. Only then should you proceed to install or launch Umamusume on Steam.
Account State and Session Safety Checks
You should be logged out of Umamusume on all other devices before initiating linking. While simultaneous sessions won’t always cause errors, they increase the risk of syncing the wrong state, especially if one device is still on a guest profile.
Also confirm that your Cygames account email and password are correct and accessible. If Steam prompts for authentication and you fumble the login, it won’t pause and ask again later; it will just bind whatever account successfully logs in first.
Understanding Umamusume Account Types: Cygames ID vs Device-Local Data
Before you even think about linking Steam and mobile, you need to understand what kind of account you’re actually playing on. Umamusume doesn’t treat all saves equally, and the difference between a Cygames ID and device-local data is the difference between seamless cross-play and permanent progress loss.
This is the point where a lot of Trainers brick their own accounts without realizing it. The game doesn’t warn you in big red letters, and Steam will not ask for confirmation if you link the wrong thing.
What Device-Local Data Really Means
Device-local data is exactly what it sounds like: your Umamusume progress exists only on that phone or tablet. It’s created when you start the game as a guest or rely solely on platform-level logins like Google Play Games or Apple Game Center.
This data does not live on Cygames’ servers in a way Steam can see. If you uninstall the app, switch devices, or attempt to log in on Steam without binding first, that Trainer is effectively invisible and treated as if it never existed.
From Steam’s perspective, device-local data might as well be a fresh reroll. No characters, no supports, no progress, no takebacks.
Why a Cygames ID Is the Only Account That Matters
A Cygames ID is the authoritative account system for Umamusume. It’s the only account type that actually stores your Trainer profile, gacha history, and progression in a way that can be accessed across platforms.
When you bind your mobile save to a Cygames ID, you’re uploading your data to Cygames’ servers and assigning it a permanent identity. That identity is what Steam looks for during first launch authentication.
Without a Cygames ID, Steam has nothing to link to. It won’t wait, it won’t prompt you to bind later, and it won’t guess which save you meant to use.
How Steam Interacts With These Account Types
On first launch, the Steam version immediately checks whether a Cygames account is logged in. If it finds one, it pulls that Trainer profile and locks it to your Steam installation.
If it doesn’t find one, Steam generates a brand-new Umamusume profile and binds it instantly. That new profile is now associated with Steam, even if your real progress still exists on your phone as device-local data.
This is where players lose accounts. Once Steam binds a fresh Trainer, you cannot overwrite it with your old mobile save later.
The One-Way Nature of Account Binding
Binding is a hard commitment. You cannot swap Cygames IDs, merge saves, or “reselect” which Trainer Steam should use after the fact.
If your mobile account is already bound to a Cygames ID, you’re safe as long as you log into that exact account during Steam’s first authentication. If it’s not bound, linking later won’t retroactively fix the mistake.
That’s why understanding your account type comes before any step-by-step linking guide. In Umamusume, account structure isn’t just a backend detail—it’s the entire foundation of cross-platform play.
Step-by-Step: Linking a Mobile Umamusume Account to Cygames ID
With the stakes clear, this is the point where you lock your progress down for good. The goal here is simple: take the Trainer profile currently living on your phone and bind it to a Cygames ID before Steam ever gets involved. Done correctly, this guarantees Steam will recognize your real account instead of rolling you into a blank save.
Prerequisites Before You Touch Anything
First, confirm you are logged into the correct Umamusume account on mobile. This should be the account with your actual characters, support cards, jewels, and event progress, not a reroll or alt. If you have multiple devices, double-check Trainer name and Player ID from the profile screen.
Next, make sure your game client is fully updated. Older versions can hide or relocate account options, and you do not want to troubleshoot UI quirks while dealing with irreversible account binding. Stable internet is also non-negotiable here, since this process writes data directly to Cygames’ servers.
Finding the Account Binding Menu in Umamusume Mobile
From the home screen, tap the Menu button in the top-right corner. Navigate to Data Link or Account Link depending on your region and client language. This is the only place where Umamusume exposes its backend account tools, and it’s intentionally buried to prevent accidental taps.
Once inside, you should see Cygames ID listed as an available linking option. If the game already shows an ID as linked, stop immediately and verify it’s the one you actually control. Linking to the wrong Cygames ID is functionally the same as handing your account to someone else.
Creating or Logging Into a Cygames ID
If you don’t have a Cygames ID yet, select the option to create one. You’ll be pushed to a browser window where you register an email and password directly with Cygames. This email becomes the master key for your Umamusume account, so use one you’ll never lose access to.
If you already have a Cygames ID from another title like Granblue Fantasy or Shadowverse, log into that existing account instead. Cygames IDs are universal across their ecosystem, and Umamusume treats them as a shared identity. Just be aware that once linked, this Trainer is permanently tied to that ID.
Confirming the Link and Uploading Your Save
After logging in, the game will prompt you to confirm the data link. This is the critical moment where your mobile save is uploaded and assigned to the Cygames ID. Read the confirmation screen carefully, especially the Trainer name shown, to ensure it matches your account.
Once confirmed, Umamusume will return you to the main menu and display a message indicating the link is complete. At this point, your progress is no longer device-local. It now exists as server-side data that Steam can authenticate against.
Verifying the Link Before Launching Steam
Do not assume the process worked without checking. Re-enter the Data Link menu and confirm that Cygames ID now shows as linked. If the option is grayed out or marked as completed, that’s your green light.
For extra safety, fully close the app and relaunch it once. If your account loads normally and the link status remains intact, your Trainer profile is secure. Only after this verification should you install or launch Umamusume on Steam for the first time.
Step-by-Step: Logging Into the Same Account on Steam (PC Version)
With your mobile data now safely anchored to a Cygames ID, the Steam side of the process is all about authentication, not transfer. You are not “moving” data to PC. You’re simply telling the Steam client to pull the exact same Trainer profile from Cygames’ servers.
Installing Umamusume on Steam
First, download Umamusume: Pretty Derby from Steam like any other PC title. There are no special launch options, beta branches, or region toggles required at this stage. Let the full install complete before launching to avoid partial downloads causing login errors.
Once installed, launch the game directly from your Steam library. The first boot may take longer than expected as it compiles shaders and checks files, which is normal. Do not force close the game during this initial startup.
Selecting Cygames ID at the Title Screen
At the title screen, Umamusume will prompt you to log in or start a new game. This is the most dangerous screen in the entire process from a data-loss perspective. Do not click any option that resembles “New Game” or “Start Fresh,” even if it looks like the default path.
Instead, look specifically for the Cygames ID login option. This usually appears as a button or menu choice related to data linking or account login. Selecting this tells the game you are pulling existing server-side data, not creating a new Trainer.
Logging Into the Correct Cygames ID
After selecting Cygames ID, a browser window will open, either in-game or externally. Log in using the exact same email and password you linked on mobile earlier. This is non-negotiable; even one different ID means a completely separate account.
If you have multiple Cygames IDs, slow down here and double-check. The login screen will not warn you if you choose the wrong one. Once authenticated, Umamusume assumes you know what you’re doing and proceeds accordingly.
Confirming Account Data on PC
After successful login, the game will return to the client and attempt to sync data. You should see a confirmation screen displaying your Trainer name and basic profile information. Treat this like checking a hitbox before committing to a risky play; if anything looks off, stop immediately.
If the name, rank, or icon don’t match your mobile account, do not proceed. Close the game and re-evaluate which Cygames ID you logged into. Continuing with mismatched data can result in the Steam client initializing a blank profile tied to that ID.
First Successful PC Login and Save Verification
Once confirmed, Umamusume will load into the main menu using your existing account. This is your proof that the link worked. Check a few high-signal indicators like owned Uma Musume, support cards, or Jewels to ensure nothing is missing.
For extra safety, fully close the Steam client and relaunch the game once. If your progress loads correctly a second time, the link is stable. From here on out, Steam and mobile are simply two front ends accessing the same Trainer data, with no further setup required.
What Data Is Shared Across Steam and Mobile — and What Is Not
Now that you’ve confirmed your account loads correctly on PC, the next thing to understand is how Umamusume actually treats cross-platform data. Steam and mobile do not function as separate save files; they are two clients pulling from the same server-side account tied to your Cygames ID. That distinction matters, because some things are perfectly synced, while others are intentionally siloed.
Progress That Is Fully Shared
All core progression is shared between Steam and mobile without exceptions. This includes your Trainer rank, owned Uma Musume, support cards, limit breaks, skill unlocks, story progress, and campaign clears. If you pull a new SSR support card on mobile, it will be waiting for you on Steam the next time you log in.
Currency is also unified. Jewels, money, fans, items, and exchange points all live server-side, meaning spending on one platform immediately affects the other. There is no delay, no manual refresh, and no way to “double dip” by swapping devices.
Gacha History, RNG, and Time-Limited Content
Gacha banners, pity counters, and pull history are shared globally across platforms. Your RNG doesn’t reset just because you switch from phone to PC, so don’t expect a fresh pity meter or hidden luck modifier. If you’re 150 pulls deep chasing a banner Uma, that count carries over exactly.
Event progress works the same way. Ongoing events, daily missions, and limited-time campaigns track progress account-wide. Clearing content on Steam instantly advances your mobile progress and vice versa, making platform switching purely a comfort or performance choice.
Platform-Specific Settings and Local Data
Not everything transfers, and this is where players sometimes get confused. Graphics settings, audio preferences, keybinds, and UI layout are stored locally per device. If your PC version is running at max settings, your phone won’t suddenly melt trying to match it.
Cached data like downloaded voice lines or assets are also platform-specific. Deleting the game or clearing cache on one device won’t affect the other, as long as your Cygames ID remains linked.
Purchases and Paid Currency Caveats
This is the most important limitation to understand before spending money. Paid Jewels are tied to the platform where they were purchased due to store policies. Jewels bought on mobile may not appear as paid currency on Steam, and the reverse is also true.
However, once paid Jewels are converted into free Jewels through spending, the resulting progress is shared normally. The game will still show your total Jewel count correctly for pulls, but the paid/free distinction can affect which bundles or discounts you’re eligible to use on each platform.
What Never Transfers Under Any Circumstances
Account links do not merge data. If you accidentally start a fresh account on Steam using a different Cygames ID, there is no way to combine it with your existing mobile progress. Think of each Cygames ID as a completely separate save slot with no rollback option.
This is why confirming your Trainer name and data during first login is so critical. Once a blank profile is initialized and linked, the only fix is logging out and starting over with the correct ID before any progress is made.
Common Account Linking Mistakes That Cause Data Loss (And How to Avoid Them)
Even though Umamusume’s linking system is straightforward on paper, most data loss horror stories come from a handful of repeat mistakes. These aren’t edge cases or freak bugs. They’re preventable errors that usually happen during first login, rushed setup, or platform hopping without double-checking IDs.
If you’re juggling Steam and mobile, understanding these traps is just as important as knowing how the link works in the first place.
Logging Into Steam Before Linking Your Mobile Account
This is the single most dangerous mistake players make. Launching the Steam version and clicking through without linking your existing Cygames ID will immediately generate a brand-new account tied to Steam.
Once that fresh profile exists, the game treats it as a completely separate save. If you then try to link your mobile account afterward, you’ll hit a wall because Umamusume does not support account merging under any circumstances.
To avoid this, always link your mobile account to a Cygames ID first, then log into Steam using that exact same ID on the very first launch. If Steam shows a Trainer name you don’t recognize, stop immediately and log out before progressing.
Using the Wrong Login Method for the Same Cygames ID
Cygames ID supports multiple login methods, including email, Apple ID, Google, and social logins. The trap is assuming these methods automatically point to the same account when they don’t.
Logging in with Google on mobile and then using email on Steam can silently create two separate Cygames IDs, even if the email address looks identical. From the game’s perspective, those are different accounts with zero shared data.
Pick one login method and stick to it across every platform. Before launching Steam, confirm which method your mobile account uses by checking the Cygames ID management page.
Skipping the Data Confirmation Screen Too Quickly
Umamusume gives you one clear warning before locking in an account. On first login, the game shows Trainer name, rank, and basic profile data, asking you to confirm it’s correct.
Players rushing to get into a race often spam confirm without reading. If that profile doesn’t match your main account, you’ve just authorized the wrong save file.
Always pause here. If the Trainer name or progress looks off by even one race, back out and recheck your Cygames ID login before continuing.
Assuming Paid Jewels Will Protect Your Account
Many players think spending money somehow anchors their account or makes it recoverable. It doesn’t. Paid Jewels don’t prevent data loss, and platform-specific store records won’t restore a mislinked account.
Worse, buying Jewels on a newly created Steam account can make players hesitate to reset, even though the progress itself is worthless compared to a fully built mobile roster. This hesitation often leads to permanent loss when the correct account could have been recovered early.
Always verify the account before making any purchases on a new platform. Treat first login like checking aggro before pulling a boss.
Deleting the App Before Confirming the Link Worked
Uninstalling the mobile app too early is another common self-own. Some players link accounts, log into Steam, see their data, and immediately delete the mobile version without testing a relog.
If something went wrong with the link or you were logged into a cached session, you may not realize the issue until reinstalling later. At that point, confusion over login methods can spiral into lost access.
After linking, log out and back in on both platforms at least once. Confirm your Trainer name and progress load correctly every time before cleaning up old installs.
Confusing Guest Data With Linked Accounts
Guest accounts feel permanent until they’re not. If you’ve been playing on mobile without linking to a Cygames ID, that data exists only on the device.
Launching Steam and linking a new Cygames ID will not pull in guest data automatically. Once the mobile app is deleted or the device changes, that progress is gone.
Before touching Steam, bind your mobile progress to a Cygames ID through the in-game menu. Consider this mandatory, not optional, no matter how casual your playtime feels.
Thinking Support Can Undo a Bad Link
Cygames support is excellent at handling bugs, but they cannot merge accounts or roll back incorrect links. If two Cygames IDs exist, they will stay separate forever.
Support may help recover access if you lose login credentials, but they won’t transfer Umas, Jewels, or progress between accounts. Planning ahead is the only real safety net.
Treat account linking like a one-time, high-stakes decision. Move slowly, verify everything, and you’ll never have to learn this lesson the hard way.
Troubleshooting, Unlinking, and Account Recovery Best Practices
Even when you follow every step correctly, account linking can still go sideways thanks to cached logins, platform quirks, or simple human error. This is where most players either save their account or permanently lose months of training, banners, and RNG luck.
Think of this section as your defensive toolkit. You’re not chasing DPS here, you’re managing risk.
When Steam Loads the Wrong Account
If Steam launches Umamusume and drops you into a fresh tutorial, stop immediately. Do not complete the race, do not claim rewards, and definitely do not spend Jewels.
Close the game, log out of the Cygames ID in your browser, then relaunch Umamusume and relink using the correct ID tied to your mobile progress. Steam aggressively caches sessions, so one bad login can snowball fast.
If you already progressed on the wrong account, abandon it. Progressing further only makes recovery more confusing, not more likely.
Account Linking Failed or Didn’t Carry Over Progress
This usually means one of three things happened: you linked the wrong Cygames ID, your mobile data was still a guest account, or you were logged into a different regional account.
Double-check the Trainer name, birthdate, and support card roster shown after login. These are faster indicators than story progress and will immediately tell you if you’re on the correct save.
If the data doesn’t match, log out and retry the link process from scratch before touching anything else. Treat it like resetting a failed run before RNG locks you out.
Unlinking Accounts: What You Can and Can’t Do
Here’s the hard truth: Umamusume does not support true unlinking. Once a Cygames ID is bound to a save, that connection is permanent.
You can log out of an ID on Steam or mobile, but you cannot detach that save and attach it to another ID. There is no respec here, only commitment.
This is why verifying the correct account before linking is more important than speed. Once the link is set, the decision is final.
Recovering an Account If You Lose Access
If you lose access to your Cygames ID credentials, recovery is still possible, but only under specific conditions. You’ll need identifying details like Trainer name, approximate account creation date, device history, and purchase receipts if available.
Cygames support can restore access to an ID, but they cannot reconstruct progress from a deleted guest account. If the data was never linked, it’s effectively gone.
Always keep a screenshot of your Trainer profile and linked email. It’s boring prep, but it’s the kind that saves entire rosters.
Best Practices to Future-Proof Your Progress
Log into your Cygames ID on both mobile and Steam at least once every few months. This keeps credentials fresh and reduces login-related issues after updates.
Avoid creating multiple Cygames IDs unless you’re intentionally running alts. More IDs means more chances to misclick, mislink, and misread confirmation screens.
Most importantly, slow down. Account management in Umamusume is not a speedrun. Treat it like lining up for a championship race: check conditions, confirm your build, then commit.
If you respect the process, your stable will follow you anywhere, from phone to PC, without ever missing a stride.
