Terms of Service

Yarn Maze (실타래 미로) · Effective date: Effective date

1. Purpose and agreement

These Terms set the conditions for using the mobile game Yarn Maze (실타래 미로, the "Game") and related services provided by Operator name (the "Operator", "we", "us"). By installing or using the Game you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the Game.

Nothing in these Terms limits rights you have under the consumer protection laws of the Republic of Korea, such as the Act on the Consumer Protection in Electronic Commerce and the Content Industry Promotion Act, or under the consumer protection laws of the country where you live.

2. Operator information

3. Definitions

• Coins: virtual currency used in the Game to get items and avatars. "Free coins" are earned by playing or watching ads; "paid coins" are bought with money.
• Items: consumable content used in the Game, such as hints, wall breakers, rewinds, and continues.
• Avatars: cosmetic content that changes the ball and the color of its thread.
• Paid content: content bought with money, such as paid coins and Remove Ads.
• Store: an app marketplace such as the Apple App Store or Google Play.

4. Changes to these Terms

We may change these Terms within the limits of applicable law. We will post the effective date and what changes on this page and in the Game at least 7 days in advance, or 30 days in advance for changes that are unfavorable to you. If you do not agree to the changes, you can stop using the Game and ask us to delete your data. If you keep using the Game after the effective date, you are treated as agreeing to the changed Terms.

5. Account and nickname

1. The Game creates an anonymous account automatically the first time you open it. There is no separate sign-up.
2. The anonymous account is tied to this installation on this device. If you uninstall the app, change devices, or clear the app's data, you may not be able to recover your progress, coins, or items. Non-consumable purchases such as Remove Ads can be recovered with "Restore purchases" using the same store account.
3. After clearing stage 5 you choose a nickname (up to 12 characters), which is shown publicly on the leaderboards. You may not use a nickname that:
   • is profane, obscene, hateful, discriminatory, or violent;
   • impersonates another person or the Operator;
   • contains someone's personal information, advertising, or contact details;
   • breaks the law or infringes someone else's rights.
   We may change or remove such a nickname.
4. You may not sell, lend, or transfer your account to anyone else.

6. The service

1. The Game is free to download and is supported by ads and paid content. From stage 16, interstitial and banner ads are shown. Rewarded ads are shown only when you choose to watch one.
2. Features that need our server, such as leaderboards, wallet sync, and purchase verification, require an internet connection.
3. We may pause the service temporarily for maintenance, equipment failure, network outages, natural disasters, or similar reasons. We will announce planned maintenance in the Game in advance.
4. We may change the Game's content (stages, items, prices, leaderboard rules, and so on). We will notify you in advance of changes that are significant or unfavorable to you.

7. Paid content and coins

1. Paid content is bought through the store's payment system. The price and contents are shown on the purchase screen; the price shown by the store, including tax, applies.
   • 500, 1,200, or 3,000 coins (consumable)
   • Remove Ads (non-consumable): permanently removes interstitial and banner ads. You can still choose to watch rewarded ads.
2. We deliver a purchase after checking the receipt directly with the store. If you paid but did not receive what you bought, please contact us.
3. Coins and items are licenses to use content within the Game only. They have no cash or other property value and cannot be exchanged for cash, moved to another account, or bought and sold.
4. Paid coins can be used for 5 years from the date of purchase. Free coins and items can be used until the service ends.
5. We may take back or correct coins and items obtained through bugs, errors, or improper means.

8. Withdrawal and refunds

1. You can withdraw from (cancel) a purchase of paid content within 7 days of buying it, or of when it became available to you.
2. Withdrawal is not available for the following. We show this on the purchase screen in advance (Act on the Consumer Protection in Electronic Commerce, Article 17(2)).
   • Paid coins you have already spent, to the extent spent. If you have used only part of a coin pack, you can still withdraw for the unused paid coins.
   • Remove Ads, which takes effect as soon as you buy it, once it has been applied.
   • Items and avatars bought with paid coins.
3. If paid content differs from how it was displayed or advertised, or was not provided as agreed, you can withdraw within 3 months of receiving it and within 30 days of when you found out, or could have found out, about the problem.
4. Payments are processed by the store, so refunds follow the store's process:
   • App Store: request at reportaproblem.apple.com
   • Google Play: request in the Google Play app under Payments & subscriptions > Budget & history, or as described in Google Play's refund policy
   If the store does not refund you but your case meets the conditions above, contact us and we will handle it as the law requires.
5. When a refund is made, the related paid coins, items bought with them, or Remove Ads are taken back. If you have already spent those coins, your balance may go below zero or some features may be limited.
6. Free coins, ad rewards, and event rewards are not refundable.

9. Purchases by minors

1. A minor needs consent from a legal guardian (such as a parent) to buy paid content.
2. If a minor made a purchase without a legal guardian's consent, the minor or the legal guardian can cancel that purchase (Korean Civil Act, Article 5).
3. A purchase cannot be cancelled if:
   • it was made within money or property the legal guardian allowed the minor to use, such as an allowance; or
   • the minor used deception to make us believe they were an adult or had a guardian's consent (Korean Civil Act, Article 17).
4. To request cancellation, send us the purchase details and a document showing the relationship between the minor and the legal guardian (such as a family relationship certificate). We use these only to confirm the request and destroy them afterward.
5. If the store account belongs to a legal guardian, we recommend using the store's parental controls, such as purchase approval.

10. Prohibited conduct

If you do any of the following, we may delete records, remove you from the leaderboards, take back coins and items, or restrict your use of the Game:

• modifying, hacking, or reverse engineering the app or server, or using automated input tools (macros);
• exploiting bugs or errors to get records, coins, or items (please report them instead);
• sending abnormal requests to our server or otherwise disrupting the service;
• buying or selling accounts, coins, or items for cash or other goods;
• impersonating others or infringing other people's rights;
• anything else that breaks the law or these Terms.

When we restrict use we will tell you the reason and the period, and you can appeal. If the restriction turns out to be our mistake, we will lift it right away and compensate you for any loss.

11. End of service

If we end the Game, we will announce the end date and the reason in the Game and on this page at least 30 days in advance. After the announcement we will stop selling paid content, and unused paid coins as of the end date will be refunded as required by law and the Korean Content User Protection Guidelines. For non-consumable paid content with no stated period of use (such as Remove Ads), the period of use is until the service ends.

12. Intellectual property

All rights in the Game, including its graphics, sounds, software, and design, belong to the Operator or the rightful owners. You receive only a personal, non-commercial right to use the Game under these Terms. You may not copy, distribute, modify, or sell it without our permission.

13. Liability

1. We are responsible under the law for damage we cause you intentionally or through negligence.
2. Unless we acted intentionally or negligently, we are not responsible for damage caused by:
   • events we cannot prevent, such as natural disasters, war, or outages at third parties like carriers or stores;
   • your own actions, such as uninstalling the app, losing your device, or breaking these Terms;
   • use of content provided free of charge.
3. Ads in the Game, and any outside services they link to, are the responsibility of the advertisers and those companies.

These Terms take effect on Effective date.
