Account sync links your game progress to an online account, so you can pick up where you left off on a new phone or tablet. It only works if the game supports it and you sign in with the same account on both devices. Check that first, before you trade in, reset or lose a phone. This guide explains how sync works, how it differs from a backup, what to do before you switch devices, and how to troubleshoot missing progress.
If you collect cards, climb divisions and work through daily quests, your progress is the whole point of the game. Losing it hurts. A few minutes of preparation prevents that.
TL;DR
- Account sync ties your progress to an online account. A backup keeps a copy you can restore later. They overlap, but they are not the same thing.
- Signing in to Google or Apple does not prove a game saves to the cloud. Google Play’s own help page warns that not every game saves progress automatically.
- Before you switch phones, confirm that your game supports cloud saves, note which account it uses, and check that your progress is current before you wipe the old device.
- If progress goes missing, the most common cause is the wrong account. Check that first.

What account sync means in a mobile game
A mobile game stores your progress somewhere. That might be only on your phone, in the game’s own servers, or in a cloud service tied to your Google or Apple account. Account sync is the arrangement where the game keeps your progress in an online place tied to an account, so another supported device can retrieve it.
In practice that means three things:
- You sign in, or link an account, on the first device.
- The game writes your state (levels, collection, currency, settings) to the online location.
- On a second device, you sign in with the same account, and the game reads that state back.
Google’s developer documentation describes this pattern as cloud saving: the game writes a player’s state to the cloud and retrieves it when the game starts. The same page notes that this lets players continue on another device and recover after a device is lost, destroyed or replaced.
For a card collection game, that state is the valuable part. Your cards, your squad, your level and your season progress all live in it.
Sync versus backup: why the difference matters
People use the two words as if they were the same. They behave differently, and the difference decides what you can recover.
| Account sync | Backup | |
|---|---|---|
| Main purpose | Keep the same progress available on more than one device | Preserve a copy so you can restore it later |
| When it updates | Usually as you play, or when the game saves | On a schedule, or when you trigger it |
| What you get back | The latest saved state | The state as of the last backup |
| Typical risk | Two devices disagree about which state is newest | The backup is old, or was never made |
The practical lesson: a sync is only as good as the last time the game wrote to the cloud, and a backup is only as good as the last time it ran. Neither helps if it never happened. That is why the checks later in this guide matter more than any single setting.
How the major platforms handle game progress
Your phone’s operating system shapes what is possible. Each platform has its own account layer, and a game can use it, ignore it, or build its own login.
Android
On Android, game saves usually rely on a Google account. Google Play’s help page on restoring game data says that, for games that support it, you should sign in with the same account you used before to restore progress on a new phone. It also says plainly that not every game saves progress automatically.
Two takeaways follow. First, the sign-in alone proves nothing. The game itself has to write the save. Second, the account has to match. If you played on one Google account and sign in to another on the new phone, your progress will not appear.
iPhone and iPad
Apple’s approach is similar. Apple Support explains that supported games use iCloud and Game Center to keep progress, high scores and saves current across your Apple devices. If progress is missing, Apple’s guidance is to first confirm that the same Apple Account is used for both services on each device.
Note the phrase “supported games.” As on Android, support is up to the game.
Moving between Android and iPhone
This is the hard case. Google’s cross-device guidance says a cloud-save solution should work across PC, Android and iOS, so players can switch platforms without losing or resetting progress. That describes what developers should aim for. It does not mean every game does it.
A Google account is not the same as an Apple account, and a game that relies only on one platform’s built-in saves will not follow you to the other. If you plan to move from Android to iPhone, or the reverse, check whether the game offers its own account or a way to link more than one sign-in option. If it does not, assume your progress stays on the platform where you built it.
Before you switch phones: a checklist
Most lost progress is lost before the new phone is even turned on. Work through these steps while you still have the old device.
- Find out whether the game supports cloud saves. Open the game’s settings and look for an account, sync, cloud or link option. Check the game’s official site or support pages for a statement about saving progress. If you find nothing, treat your progress as stored on the device only.
- Note which account the game uses. If you signed in with Google, write down which Google account. If you use Apple, write down which Apple Account. People with two or three accounts often sign in with the wrong one later.
- Play a short session and let the game save. Many games write progress at the end of a match or when you leave a screen. Finish a match, return to the main menu, and give the game a moment on a good connection.
- Check that your device backup is recent. If your phone backs up app data through the operating system, make sure the latest backup finished. Apple and Google both describe their own backup features on their support sites.
- Keep the old phone until you have verified the new one. Do not wipe, sell or trade in the old device until you have signed in on the new one and seen your progress with your own eyes.
- Install the game on the new phone and sign in with the same account. Do this before you start any new game, if you can. Starting fresh can create a second save that you may later have to choose between.
- Compare what you see. Check your level, your collection and your squad. If they match what you had, you are done. If they do not, stop and read the troubleshooting section before you play further.
Step 7 deserves emphasis. Progress made on a new, empty profile can overwrite or compete with the real one, depending on how the game resolves conflicts.
What may and may not carry over
A sync moves the data the game chooses to save. That is usually the important part, but not always everything.
Likely to carry over when a game supports cloud saves:
- Your collection and unlocked items
- Your level and progression
- Your squad or deck setup
- Game currency and rewards you have already earned
Less certain, and worth checking in the game’s own help:
- Settings such as sound, language or notification preferences
- Progress in a mode that is tied to a time-limited event
- Anything that depends on the store you bought it from, such as purchases
- Data that lives only on the device, such as temporary files and cached downloads
For time-limited modes, the safest habit is to finish or save before you move. Weekly leaderboards and monthly season resets run on their own clocks, and a delay on your side can cost you a ranking you worked for.
Why conflicts happen
When the same account runs on two devices, the game can end up with two different versions of your progress. Google’s developer documentation says games must account for conflicts between local and cloud states, including cases where the same user plays on multiple devices or uses multiple accounts.
Here is a simple example. You play on your old phone on Monday, then open the game on your new phone on Tuesday before the old phone has uploaded its last session. The cloud holds Monday morning’s state, and the old phone holds Monday night’s. The game has to choose one. Depending on its design, it may ask you, or it may pick the newest, or it may pick the cloud copy.
Three habits reduce the risk:
- Play on one device at a time while you are moving.
- Let each session end cleanly before you switch.
- If the game asks which save to keep, read the details (level, time played, last saved) before you pick.
Troubleshooting missing progress
If your cards, level or squad are not there, work through this list in order. It goes from the most common cause to the least.
Check the account first
The wrong account is the usual culprit. On Android, confirm the Google account on the new phone matches the one you used before, as Google Play’s help page advises. On iPhone, Apple’s guidance is to confirm the same Apple Account is used for iCloud and Game Center on every device.
Confirm the game supports saving
If you cannot find any sync or cloud option in the game and its help pages say nothing, the game may not save to the cloud at all. In that case there may be nothing to restore from the account, and the game’s support team is your next step.
Check your connection and update the game
A weak connection can stop the game from reaching its servers. Switch to a stable Wi-Fi network, update the game from the store, and open it again. An outdated version may not read a newer save.
Look for a second profile
If you started playing on the new phone before signing in, you may have created a new profile. Look in the game’s settings for a way to switch accounts or load a different save. Do not keep playing on the new profile until you understand which save the game will keep.
Contact the game’s support team
If none of this works, contact the developer’s support with details: your device model, your operating system, the account you used, your player name or ID, and roughly when you last played. Screenshots of your old profile help.
Perspective: why we care about this
We build Vladers around collecting and competing, so here is exactly how it handles your progress. Your cards, squad, coins and level are stored on our servers, not only on your phone. You can start playing straight away as a guest, with no account. A free account, created with an email address, a username, or Apple or Google sign-in (Google sign-in works on Android only for now), keeps that progress on any device you log in from, including when you move between Android and iPhone. If you register after playing as a guest, the progress you made carries over to your new account. An account also unlocks Vladers League, Weekly Clash, Story Mode and Away Missions.
So our advice is simple. If you are still playing as a guest, register before you change phones, because a guest session belongs to the device you started on. Then log in with the same account on the new phone, and keep the old phone until the new one shows your squad exactly as you left it. We also believe progress should not depend on spending money: Vladers is free to play, progression does not require any purchase, and rewarded ads are optional.
If something looks wrong after you log in, check that you used the same email, username, Apple or Google account as before, then contact us from the game’s settings with your username.

Play Vladers on your next phone
If you like fast matches and collecting, Vladers is a free football card game built around real-time reaction duels. You tap faster than your opponent to win possession, then use your card stats, formation, special actions and powers to create scoring chances. Modes include Vladers League with live PvP and monthly season resets, Weekly Clash, Story Mode with fire, water, earth and wind trials, Season and Cup, Friend Challenges and Away Missions. It is available in English, French and Spanish.
When you are ready to build your squad, try the Vladers football card game and take your first pack into a match.
A short routine to keep your progress safe
You do not need to think about this every day. A light routine is enough:
- Once, when you start a new game: find the account or sync option and read what it says.
- Every few months: confirm your phone’s own backup is still turned on and finishing.
- Before any device change: follow the checklist above, and keep the old phone until you verify the new one.
- After any big milestone: let the game save, then close it cleanly.
This routine takes minutes. Recovering a lost collection, if it is possible at all, takes far longer.
FAQ
Is account sync the same as a backup?
No. Sync keeps your progress available across devices through an online account, usually updating as you play. A backup preserves a copy you can restore later. A good setup uses both, but each can fail on its own, so check them separately.
Will my progress move automatically when I get a new phone?
Only if the game supports it and you sign in with the right account. Google Play’s help says not every game saves progress automatically. Check the game’s settings and support pages before you switch, and keep the old phone until you have confirmed your progress on the new one.
Can I move my progress between Android and iPhone?
Sometimes, but only if the game offers its own account or another cross-platform option. A Google account does not work as an Apple account, and platform saves are separate. Google’s developer guidance says cloud saves should work across Android, iOS and PC, but that is a goal for developers, not a promise for every game.
Why is my progress missing after signing in?
The most likely reason is that you used a different account. Confirm the account, check your connection, and update the game. On iPhone, Apple recommends confirming the same Apple Account is used for iCloud and Game Center. If that does not help, contact the game’s support with your player ID and device details.
Can I play on two devices at once?
It is risky. When two devices hold different versions of your progress, the game has to resolve the conflict between local and cloud states, and the result is not always the one you want. Play on one device at a time, especially while you are moving to a new phone.
