Terms of Service

Hero's Journal: Idle RPG

Effective date: 2026-10-26

Article 1 (Purpose)

These Terms set out the conditions for using the mobile game Hero's Journal (영웅의 성장일지) (the "Game") provided by TERAGAMEZ (the "Company"), and the rights and obligations of the Company and its users.

Article 2 (Effect and changes)

  1. These Terms apply to everyone who installs and uses the Game.
  2. The Company may change these Terms within the limits of applicable law, and will announce changes on this page and in the Game 7 days before they take effect (30 days for changes unfavourable to users).
  3. If you do not agree, you may stop using the Game and request deletion of your account. Continuing to use the Game after the effective date means you accept the change.

Article 3 (Account)

  1. There is no sign-up. On first launch the Game automatically creates a guest account from a device ID and saves your progress on the Company's server. We do not collect your name or email.
  2. A guest account is tied to its device. If you use Link Google Play account in Settings, you can continue your progress on another device with the same Google Play account. If you change devices or clear app data without linking, your progress may not be recoverable.
  3. You can keep playing from the on-device save when the server is unreachable; it syncs when the connection returns. Features that need server confirmation, such as purchases, are available only while connected.
  4. An account has hero slots: 1 by default, up to 4 with a paid item. Each slot holds an independent hero (class, level, gold, equipment, codex, stage, etc.). Magic Stones, the ad-removal pass and purchase history are shared by all slots of the account. Offline rewards accrue only to the slot currently selected.

Article 4 (Service)

  1. The Game is free to download. Some items are paid (Article 5), and there are optional rewarded ads (Article 8).
  2. The Company may change Game content (balance, stages, equipment, shop items, etc.) through updates for operational or technical reasons.
  3. If the Company ends the Game, it will give at least 30 days' notice in the Game, on the store listing or on this site.

Article 5 (Magic Stones and paid items)

  1. Through Google Play billing or the Apple App Store you can buy the premium currency Magic Stones and bundles (e.g. Starter Pack, Growth Pack, Ad-removal pass, Unlock slot). Contents and prices are shown in the shop before purchase.
  2. Magic Stones can be exchanged in the shop for equipment chests, enhancement scrolls, spellbook pages and similar items. They can also be earned through play — the free reward box, first stage clears, dungeons and more.
  3. The Company's server record is authoritative for your Magic Stone balance, which all slots share. One-time items can be bought once per account.
  4. Gold can be transferred between slots only if you own at least one extra slot; 50% of the transferred gold is taken as a fee and the rest arrives in the current slot.
  5. Magic Stones and items are digital content usable only in the Game. They have no cash value, cannot be exchanged for money, and may not be transferred or sold to others.

Article 6 (Randomised items)

  1. The Game contains randomised items. Opening a Standard or Premium Equipment Chest determines the grade (Common, Uncommon, Rare, Epic, Legendary, Mythic) and item by probability. Equipment from battles, offline rewards and dungeons is also random.
  2. The grade probabilities of each chest are shown under View odds in the shop and in the purchase confirmation, based on your current stage. Because the equipment sets available depend on the stage, the odds can change; the updated odds are shown in the same place.

Article 7 (Payment, withdrawal and refunds)

  1. Payments are processed by Google Play or the Apple App Store. The Company does not receive card or other payment details.
  2. Refunds follow each store's procedures and policies (Google Play: request from your order history / Apple: reportaproblem.apple.com).
  3. Your rights under the Korean Act on Consumer Protection in Electronic Commerce and other applicable laws are not limited by these Terms. However, under Article 17(2) of that Act, withdrawal may be restricted for digital content already used (e.g. spent Magic Stones, opened chests).
  4. If a minor paid without a legal guardian's consent, the minor or the guardian may cancel the payment as provided by law.
  5. When a store refund is made, the Company takes back what that purchase granted: Magic Stones up to your remaining balance, effects such as the ad-removal pass are turned off, and a refunded slot is locked (its data is preserved). Anything already spent that cannot be taken back is recorded, and repeated cases may lead to restrictions under Article 9.
  6. If you were charged but did not receive the item, contact us with the order number from your store receipt.

Article 8 (Rewarded ads)

  1. The Game has rewarded ads (free reward box, extra dungeon entry, double offline reward, boss revive). Ads play only when you tap an ad button, and the reward is given only if you watch to the end. Daily use is limited.
  2. Accounts that bought the ad-removal pass receive those rewards without watching ads.
  3. Ads are provided by Google AdMob and may not always be available. 

Article 9 (Prohibited conduct and restrictions)

  1. You must not:
    • tamper with game files, save data or network traffic, or obtain currency, items or progress by abnormal means;
    • abuse payment or refund systems, such as repeatedly requesting refunds for items already used;
    • reverse-engineer, copy, modify or redistribute the Game, or infringe the intellectual property of the Company or third parties;
    • otherwise violate the law.
  2. The server checks whether saved progress is achievable through normal play. If progress looks abnormal the Company may hold back some rewards for that account, and if prohibited conduct is confirmed it may restrict use for a set period or permanently. If you disagree, contact us at the email below.

Article 10 (Intellectual property)

Rights to the Game's software, art, text, music and other content belong to the Company or their rightful owners. Some art, fonts and sounds are used under their creators' licences.

Article 11 (Account deletion)

You may request deletion of your account at any time; A deleted account and the Magic Stones and items in it cannot be restored.

Article 12 (Limitation of liability)

  1. The Company is not liable for service interruptions caused without its intent or negligence, such as failures of stores, ad networks or carriers.
  2. The Company is not liable for progress lost for reasons attributable to the user, such as clearing app data or losing or replacing a device without having linked Google Play.
  3. To the extent permitted by law, the Company is not liable for free portions of the service except for damage caused by its intent or gross negligence.

Article 13 (Governing law and disputes)

These Terms are governed by the laws of the Republic of Korea. We will first try to resolve disputes by email; otherwise they will be settled by the competent court under the Civil Procedure Act. Where the consumer-protection laws of your country of residence give you greater protection, those laws prevail. The Korean version prevails if the two versions differ.
