Terms of Service

Service: Core Breaker · Package: com.lemoncube.corebreaker
Effective: August 9, 2026 · Last updated: August 26, 2026 (amendment effective September 2, 2026)

1. Purpose

These Terms govern your use of the mobile game Core Breaker (“the Game”) and related services provided by Lemon Cube Studio (“we”), and set out the rights, obligations, and responsibilities of both parties.

2. Definitions

• Service: the Game and all services incidental to it
• User: anyone who uses the Service under these Terms
• App store: the operator that distributes the Game and processes payments (Google Play and similar)
• Paid items: in-game products purchased for a fee
• Game data: your progress — currency, facilities, stage progression, and characters
• Cloud save: backup and restore of game data, available only while you are signed in with a Google account

3. Posting and amendment of these Terms

We publish these Terms in the Game or on our website. We may amend them within the limits of applicable law. We will announce any amendment, with its effective date and reason, at least 7 days in advance, or at least 30 days in advance where the change is unfavourable or material to users.

If you do not accept an amendment, you may stop using and uninstall the Game. Continuing to use the Service after the effective date constitutes acceptance.

4. Provision of the Service and accounts

The Game is provided without registration, and every part of it is playable as a guest. Cloud save requires signing in with a Google account, which is your choice to make. We use that account solely to identify the owner of a cloud save; we do not create separate game accounts or grant tiers or privileges through it.

You can sign out or delete your account at any time from the in-game settings. Deleting your account removes the cloud backup and the authentication account; the processing involved is described in our Privacy Policy.

We aim to keep the Service continuously available. Because the Game runs primarily on your device, it may function independently of our servers. We may change the Game's structure, values, and content in order to improve the Service.

5. Storage and loss of game data

Game data is stored on your device by default. While you play as a guest it is not transmitted to or retained by us. If you sign in and use cloud save, a backup of your game data is stored on Google Firebase, which we use for this purpose, and only your own account can access that backup.

If you used cloud save, signing in with the same account restores the data from your most recent backup. Progress made after that backup, backups deleted through account deletion, and data replaced when you overwrite another device's backup cannot be recovered.

6. Paid items

The Game may offer the following types of paid items:

• Consumable: in-game currency that is depleted when used
• Time-limited: benefits provided for a defined period
• Permanent: a one-time purchase that continues to apply (such as ad removal)

All payments are processed by the app store. We do not collect or retain your payment credentials. Prices and contents are shown on the purchase screen. We may change them with prior notice; such changes will not worsen the terms of items you have already purchased.

7. Withdrawal and refunds

Refunds for paid items follow the refund policy and procedure of the app store through which you paid. Refund requests should be submitted to that app store; we will cooperate as needed.

Under the Korean Act on Consumer Protection in Electronic Commerce, users may withdraw a purchase within 7 days. However, withdrawal may be restricted for items already used or that take effect immediately and cannot be restored; where this applies, it is indicated before purchase. Users in other jurisdictions retain any mandatory rights granted by their local law.

Purchases by minors: where a minor makes a purchase without the consent of their legal guardian, the minor or the guardian may cancel that purchase, subject to the exceptions provided by law. Please contact us or the app store to request this.

8. Advertising

The Game shows no forced interstitial advertising. Ads are rewarded ads that play only when you deliberately tap a button to watch one. The reward and any daily limit are shown in the Game.

Personal data handling related to advertising is governed by our Privacy Policy.

9. User obligations

You must not:

• Modify or reverse-engineer the game client, save files, or network data
• Obtain currency, items, or progression by abnormal means, or circumvent payment processes
• Use automation such as macros or bots
• Reproduce, distribute, or create derivative works from our content without permission
• Otherwise violate applicable law or interfere with the normal operation of the Service

Where such conduct is identified, we may restrict use of the Service or reclaim abnormally obtained currency and progression.

10. Intellectual property

All rights in the Game and its software, graphics, text, audio, and characters belong to us or to the rightful owners. You are granted a right to use the Game for personal, non-commercial purposes only, and may not reproduce, distribute, or sell it without our prior consent.

Capturing or recording your own gameplay and sharing it on your personal channels is permitted, provided it does not amount to unauthorised commercial exploitation.

11. Suspension and termination of the Service

We may change or discontinue all or part of the Service for business, technical, or force majeure reasons. If we discontinue the Service, we will give notice in the Game or on our website at least 30 days before the closure date.

On discontinuation, refunds for unused paid currency will be handled in accordance with applicable law and app store policy.

12. Limitation of liability

• We are not liable for service disruption caused by events beyond our reasonable control, including natural disasters, carrier outages, and changes to app store or device manufacturer policy.
• We accept no obligation to restore or compensate for loss of game data we do not hold, as described in Section 5 — guest data kept on your device, backups you deleted by deleting your account, and the like.
• We are not liable for a user's failure to obtain the enjoyment or results they expected from the Service.
• Nothing in this Section limits our liability for wilful misconduct or gross negligence, or any liability that cannot be excluded under applicable law.

13. Governing law and disputes

These Terms are governed by the laws of the Republic of Korea. We will first seek to resolve any dispute through good-faith discussion. Failing that, either party may bring proceedings before the court having jurisdiction under the Korean Civil Procedure Act. This does not deprive consumers of the protection of mandatory provisions of the law of their country of residence.

14. Business information and contact

Addendum

These Terms take effect on August 9, 2026.

The amendment of August 26, 2026 (Sections 2, 4, 5, and 12 — cloud save and account clauses) takes effect on September 2, 2026.
