ARTICLE 3 — THE PLATFORM AND THE SERVICES

3.1 Nature of the Platform. JOYBOX is a mini-game aggregation platform. The Operator aggregates multiple Mini-Games and makes them available to Users in a single Platform. The Operator may add, update, replace, or remove any Mini-Game or other content on the Platform at any time at its discretion, and may launch new functions or discontinue existing functions from time to time.

3.2 Guest Access. Certain Mini-Games may be played in Guest Mode, that is, without registration or login. Guest Mode is provided for convenience only and is subject to limitations, including without limitation: (a) In-App Purchase functions are unavailable in Guest Mode; and (b) game progress, records, and other data generated in Guest Mode may be temporary, may not be saved or synchronized across devices, and may be lost or cleared upon cache clearing, application update, device change, long-term inactivity, or for other technical reasons. The Operator has no obligation to preserve, back up, or recover any data generated in Guest Mode.

3.3 Login Required for In-App Purchases. Where a Mini-Game involves In-App Purchases, you must register an Account, complete any required verification, and log in to the Platform before you may use the In-App Purchase and related paid functions of that Mini-Game. In-App Purchase transactions completed while you are logged in are recorded in your Account, and Virtual Items acquired are credited to your Account for use in accordance with the applicable game rules.

3.4 Changes to the Services. The Operator may modify, upgrade, suspend, or discontinue any part of the Services at its discretion. Where a change materially affects your use of the Services, the Operator will use commercially reasonable efforts to notify you through announcements on the Platform or other reasonable means.

3.5 Third-Party Mini-Games. Certain Mini-Games on the Platform are developed and provided by third-party developers or publishers. The Operator aggregates and distributes such Mini-Games but does not control their internal designs, rules, or content. The Operator may remove from the Platform any Mini-Game that violates this Agreement or applicable rules.

ARTICLE 4 — ACCOUNT REGISTRATION AND SECURITY

4.1 You may register an Account by providing the information required by the Platform and completing the verification procedures as prompted. You shall provide true, accurate, current, and complete registration information and shall promptly update such information when it changes.

4.2 You are responsible for properly safeguarding your Account credentials, including your password and any login or verification means. You are responsible for all activities carried out through your Account, whether or not authorized by you. If you suspect any unauthorized use of your Account, you must notify the Operator immediately through the channels published on the Platform.

4.3 Accounts registered through automated or fraudulent means, and Accounts registered in breach of this Agreement, may be suspended or cancelled by the Operator at its discretion.

4.4 The Operator may suspend, restrict, or deactivate an Account that has been registered with false information, obtained by fraud, used in breach of this Agreement, or inactive for 【e.g., twelve (12) consecutive months】, in each case where permitted by applicable law and, where practicable, after reasonable notice to you.

ARTICLE 5 — IN-APP PURCHASES, PAYMENT, AND VIRTUAL ITEMS

5.1 In-App Purchases are available only to registered Users who are logged in to their Accounts. Before completing an In-App Purchase, you should carefully review the price, quantity, description, and terms of the Virtual Items or Paid Features displayed at the time of purchase. If you are a minor, you must obtain your parent's or legal guardian's consent before making any In-App Purchase.

5.2 All payments for In-App Purchases are processed through the available Payment Channels. Prices displayed on the Platform include applicable taxes or, where taxes are displayed separately, are exclusive of such taxes. Billing and payment handling by a Payment Channel are further subject to the terms of that Payment Channel.

5.3 Upon successful payment, the Virtual Items you have purchased will be credited to your Account and made available for use in accordance with the rules of the applicable Mini-Game.

5.4 License to Virtual Items. Virtual Items constitute a limited, personal, non-exclusive, non-transferable, and revocable license to use the relevant virtual goods within the Platform, and are licensed to you rather than sold. Virtual Items have no cash value, are not redeemable or exchangeable for cash or other value, and may not be traded, sold, transferred, or converted except through functions expressly provided by the Platform or the applicable Mini-Game.

5.5 The Operator may adjust the prices, contents, or availability of Virtual Items and other Paid Features from time to time with prospective effect. Price adjustments do not affect transactions already completed.

5.6 If you identify any billing error or any transaction that you did not authorize, you should contact the Operator at joybox-global@huya.com promptly and provide the relevant transaction information.

ARTICLE 6 — REFUND POLICY FOR PAID FEATURES

6.1 No Refund. You acknowledge and agree that, except as required by mandatory applicable law, all Paid Features on the Platform, including Virtual Items, are provided on a non-refundable basis. Once an In-App Purchase transaction is completed and the relevant Virtual Items or Paid Features have been delivered or credited to your Account, the Operator does not support or provide refunds for such transaction.

6.2 Scope of the No-Refund Policy. The no-refund policy in Article 6.1 applies regardless of: (a) whether the Virtual Items have been consumed or remain unused; (b) whether the relevant Mini-Game is subsequently modified, suspended, or removed from the Platform; (c) whether your Account is suspended, restricted, or terminated in accordance with this Agreement; (d) your dissatisfaction with any Mini-Game, Virtual Item, or other Paid Feature; or (e) any other circumstances, in each case subject only to mandatory applicable law.

6.3 Chargebacks. You shall not initiate a chargeback or payment dispute in respect of an In-App Purchase without first contacting the Operator. If you initiate an unauthorized chargeback, the Operator may, to the extent permitted by applicable law, suspend or restrict your Account, recover the relevant Virtual Items, and pursue any other remedies available to it.
