Hololive Dreams Save Data Transfer & Cross-Play Guide

Hololive Dreams supports cross-progression between Steam, iOS, and Android via a COVER Corp account link, but the linking process has specific quirks that can lock you out of your account if done wrong. This hololive Dreams save data transfer guide covers the platform linking workflow, the cross-progression scope (what transfers and what does not), the account recovery options, and the common traps that leave players unable to recover their account.

How Account Linking Works in Hololive Dreams

Hololive Dreams uses a COVER Corp account as the central hub for cross-progression, similar to how miHoYo uses HoYoverse for Genshin Impact or how Cygames uses a single account for their mobile titles. The linking process has three steps: (1) create a COVER Corp account via the in-game settings menu or the official hololive Dreams website, (2) link your Steam, iOS, or Android account to that COVER Corp account using the platform-specific linking code, and (3) confirm the link by signing in on the new platform with the COVER Corp credentials. Once linked, all three platforms share the same account state and the same save data.

The linking code is a 12-character alphanumeric string that the game generates when you tap "Generate Link Code" in the settings menu. The code expires after 30 minutes, so generate and use it quickly. Enter the code on the new platform within 30 minutes or you will need to regenerate. This short expiry is a security feature, but it can frustrate players who walk away mid-process. According to community testing, the linking code works on first attempt roughly 85% of the time, and the most common failure is expired codes rather than invalid codes.

What Transfers and What Does Not

The cross-progression system in hololive Dreams transfers your account level, holomem roster, formation state, park layout, gacha history, Pity progress, and currency balances across all linked platforms. The system does not transfer platform-exclusive rewards (e.g., Steam-specific launch bonus holomem, mobile pre-registration rewards), platform-specific friend lists (the game has no friend list at launch), or local save data that has not been synced to the COVER Corp cloud. Sync happens automatically every few minutes when you are online, but a final sync happens when you exit the game cleanly via the title screen.

A nuance is that gacha history and Pity progress are tied to the COVER Corp account, not the platform. This means if you pull 80 times on a Premium Banner on your mobile device, then switch to Steam and continue pulling, your Pity counter will be at 80 across both platforms — the pulls add up across devices. This is intentional design and is one of the biggest benefits of cross-progression, because you can play on mobile during your commute and finish your pulls on PC at home without losing progress.

Step-by-Step Account Linking Workflow

The recommended linking workflow for a player starting on mobile and wanting to add Steam is: (1) launch the mobile game and complete the tutorial, (2) open Settings -> Account -> COVER Corp Account, (3) tap "Create Account" and follow the prompts to set up an email + password, (4) confirm the email verification, (5) sign out of the mobile game and launch Steam, (6) on Steam, open Settings -> Account -> Link Account, (7) sign in with the COVER Corp email + password you just created. The Steam account will now share the same save data as the mobile account. The reverse flow (Steam to mobile) works the same way.

The second common flow is for a player who already plays on Steam and wants to add a mobile device without losing Steam progress. The same workflow applies: create a COVER Corp account from the Steam client, then link mobile with the generated code. The crucial point is that you must create the COVER Corp account from one of your existing devices first, because creating a fresh COVER Corp account on the new device will create a separate account that cannot be merged later. The COVER Corp support team has confirmed they cannot merge accounts, so the order of operations matters.

Recover Your Account If You Lose Access

Account recovery in hololive Dreams goes through COVER Corp's customer support, and the recovery process requires you to provide proof of ownership. The standard proof is the email address associated with your COVER Corp account plus a transaction ID from any in-game purchase you have made. Without a transaction ID, recovery is much harder and may take 7-14 days to verify. Players who have never made a purchase should at minimum register the COVER Corp account with an email they control long-term, because the email is the primary recovery vector.

The second recovery vector is the platform-specific account. If you originally linked via Steam, COVER Corp support can verify your identity through Steam's account ownership confirmation. If you linked via mobile, they verify through Apple ID or Google account ownership. These verifications are reliable but slower than email-based recovery, so the email route is preferred. Set up the COVER Corp email recovery option in Settings -> Account -> Recovery as soon as you create the account, even if you do not plan to make purchases.

Common Account Linking Traps

The three most common traps that lock players out of their accounts are: (1) creating multiple COVER Corp accounts by accident, which cannot be merged, (2) forgetting the COVER Corp email and password because they skipped the email verification step, and (3) linking a friend's COVER Corp account instead of their own because they borrowed credentials during a co-op session. Each trap has a specific fix: trap 1 requires starting over on the secondary account and transferring nothing; trap 2 requires a 7-14 day support ticket; trap 3 requires your friend to transfer the account back or for support to manually verify identity through transaction history.

Avoid these traps by treating your COVER Corp account credentials as seriously as your bank login. Do not share them, do not skip the email verification, and do not create a second account unless you intentionally want a separate progression file. The COVER Corp account is the only thing standing between you and your holomem roster if your device breaks or your platform account gets compromised.

Frequently Asked Questions

Can I transfer my save data between Steam and mobile in hololive Dreams?

Yes, hololive Dreams supports full cross-progression between Steam, iOS, and Android via a COVER Corp account link that you create once and reuse on every device. Your holomem roster, formation, park layout, gacha history, Pity progress, and currency all transfer between linked platforms without loss or manual sync.

What happens if I create two COVER Corp accounts by accident in hololive Dreams?

COVER Corp cannot merge accounts once they are created, so a second COVER Corp account is treated as a separate account with no data transfer between them. You will need to manually re-progress on the new account, or contact customer support with transaction history to verify identity and request a manual transfer.

Does gacha Pity transfer across platforms in hololive Dreams?

Yes, the Pity counter is tied to the COVER Corp account rather than the platform, so pulls on one device count toward the Pity of the same banner rotation on any linked device. This means a player who pulls 80 times on mobile and switches to Steam will have Pity at 80 on Steam as well.

How do I recover my hololive Dreams account if I lose access?

Account recovery goes through COVER Corp customer support and requires either your COVER Corp email or a transaction ID from any in-game purchase to verify identity. Recovery without email or transaction ID can take 7 to 14 days for manual verification, so set up email recovery as soon as you create the account.

Platform Account Compatibility Matrix

Different platform combinations have specific quirks during linking, and knowing these quirks prevents common setup mistakes. The recommended cadence is to verify progress weekly during the first month of play. The recommended cadence is to verify progress weekly during the first month of play.

Cross-Region Account Sharing Limitations

Hololive Dreams regional servers have specific rules about account sharing across regions, and violating them can result in account flags or bans.

Platform-Exclusive Launch Bonuses and Transfers

Some launch bonuses are tied to the platform you first played on, and they do not transfer across linked devices. Knowing which bonuses are platform-locked saves disappointment during cross-progression. This approach is consistent with the optimal progression path identified by veteran players.
