1. How to contact us
In the game, open Settings > Support > Contact. This opens an email with your app version and device details already filled in, which lets us look into your case fastest. If you write to contact@lemoncubestudio.com directly, please include:
- Your Player ID shown at the bottom of the Settings screen (CB-XXXX-XXXX)
- For purchase issues, the order number (starts with GPA) and the time of purchase
- A screenshot of the screen where the problem occurred
We reply in order on business days. If a case needs investigation, we first confirm receipt and then follow up with the result.
2. Refunds and withdrawal
All Core Breaker purchases are made through Google Play, and refunds follow Google Play's policy and procedure. We do not store your payment details.
How to request a refund
- Open the Play Store app, tap your profile, then Payments & subscriptions > Budget & history.
- Select the order and tap Request a refund or Report a problem.
- Google Play decides the outcome and notifies the email address registered with Google.
If Google Play cannot process your case, email us with the order number. We cooperate to the extent required by applicable law and Article 7 of the Terms of Service.
Withdrawal
Under Korea's Act on the Consumer Protection in Electronic Commerce, you may withdraw a purchase within 7 days. Withdrawal may be limited for items that have already been used or take effect immediately and cannot be restored. In Core Breaker this applies to:
- In-game currency such as bills, gold, or core shards that is granted instantly and has been spent
- Supply crates (work orders) that have already been opened
- Timed or permanent items whose effect has started, such as the ad-free pass or paycheck
Items after a refund
When a refund is issued, we do not take back in-game currency or items that were already granted. This is not an error, and you may purchase the same product again without restriction. Action on repeated refunds is governed by Google Play's policy.
Purchases by minors
If a person under 19 made a purchase without consent from a legal guardian, the minor or the guardian may request cancellation. Cancellation may be limited where the minor paid with funds the guardian permitted them to use, or misrepresented themselves as an adult. Please contact Google Play or email us.
3. Frequently asked questions
Q1. My progress disappeared. I switched phones and the game started over.
If you ever signed in with a Google account under Settings > Cloud Backup, your progress can be restored. Sign in with the same account on the new device and tap Restore. The confirmation shows the last backup time and device name so you can check it is yours. The app closes once after restoring; launch it again to continue. Only the most recent backup is kept, so progress made after it cannot be restored.
Q2. I played without signing in and uninstalled the app.
Progress without sign-in is stored only on your device. Once the app is uninstalled or the device is changed, there is no copy on our side and it cannot be recovered. If the app is still installed on the same device, try Settings > Cloud Backup > Restore first. Signing in with a Google account in Settings lets you continue on any device in the future.
Q3. My backup is not uploading.
Right after sign-in, if a backup from another device is found, automatic backup is paused so that the empty save on the new device does not overwrite it. Tap Restore to pull the existing backup, or Back up now to overwrite it with this device's progress. Automatic backup then resumes.
Q4. I paid but did not receive the item.
First fully close the app and launch it again with a network connection. If the app was closed or the connection dropped right after payment, delivery is completed on the next launch. If it still does not appear, send us the order number (starts with GPA) and the time of purchase. If there is no completed payment record, a temporary card authorization is released automatically within a few days.
Q5. How do I get my ad-free pass or welcome kit back?
Products tied to your account can be restored with Restore purchases at the bottom of the cash shelf in the Trading Post, or under Settings > Support > Restore purchases. Tapping it repeatedly never grants duplicates. Consumable products such as bill packs, paychecks, and supply crates cannot be restored.
Q6. How do I get a refund?
Follow the steps in 2. Refunds and withdrawal in the Play Store app. We do not approve or deny refunds ourselves; Google Play decides according to its policy.
Q7. I got a refund but the items are still there.
This is expected. We do not take back in-game currency or items that were already granted. You may keep using them, and you may buy the same product again.
Q8. My coupon code is not accepted.
Coupons are entered in one place only: Settings > Support > Redeem code. Enter the code exactly as given, including hyphens, with no leading or trailing spaces. If it says the code was already redeemed, check your mailbox in the game first. Expired codes are not extended, and codes not issued by us are not honored.
Q9. How do I delete my account?
In the game, go to Settings > Cloud Backup > Delete account. This removes the cloud backup, the sign-in account, and the save on this device. It cannot be undone, and playing again starts a completely new record. If you are asked to sign in again during deletion, do so and retry. To remove only the on-device data, uninstall the app or clear its data in your device settings.
Q10. Where can I see the supply crate drop rates?
Open Drop Rates on the Gear screen in the game to see the grade probabilities, pity rules, and your current counters. The same information is published on this site at Drop Rates. Crates earned for free and crates purchased use the same probability table and the same pity counters.
