General provisions 1.1. Purpose and Scope These Terms of Service (hereinafter "Terms") constitute a legally binding agreement between Jackz Intelligent Technology Co., Ltd. (株式会社 Jackz Intelligent Technology), the operator of the "Cardz.game" platform (hereinafter "the Company"), and the individual (hereinafter "User") regarding the use of the platform (hereinafter "the Service"). By registering an account, purchasing Cardz Game Points, or using any feature of the Service, the User agrees to be bound by these Terms. Acceptance applies at account registration and again at each purchase, and the version of these Terms in effect at the time of a transaction governs that transaction. 1.2. Relationship to Other Rules Any separate rules, guidelines, probability tables, shipping policies, or help center articles posted by the Company on the Service form an integral part of these Terms. In the event of a conflict, the specific rule shall prevail solely for that subject matter. 1.3. Modification of Terms The Company may modify these Terms at its discretion. For material changes, the Company will provide reasonable advance notice through the Service or by email. Modifications take effect upon posting on the Service unless otherwise stated. Continued use of the Service after any change constitutes acceptance of the revised Terms. 1.4. Electronic Communications By using the Service, the User consents to receive communications from the Company electronically, and agrees that electronic records maintained by the Company have the same legal effect as paper records. Automated or operational messages, including allocation notices, shipping notices, and correction notices, do not modify these Terms, do not create title or other rights beyond these Terms, and do not waive any right of the Company. The Company may correct an erroneous communication. In the event of any inconsistency, the Company's records and these Terms prevail. 1.5. Privacy The Company handles personal information in accordance with its Privacy Policy posted on the Service. This includes the use of account, device, and transaction information for fraud prevention and security purposes. ## Article 2. Definitions For the purposes of these Terms: 1. "User": An individual who has registered an account on the Service and satisfied the eligibility requirements. 2. "Cardz Game Points" or "Points" or "Pts": A prepaid balance issued by the Company, purchased with money, usable solely within the Service. There is only one such balance. Cardz Game Points have zero cash value and cannot be redeemed for money. 3. "Gems": Promotional credits granted by the Company without monetary consideration through campaigns or promotions, subject to the rules of the applicable promotion. 4. "Mystery Pack" (Gacha): A purchase mechanism where the User expends Points or Gems to receive a randomized Card. 5. "Card": A collectible item shown in the User's collection within the Service as the result of opening a Mystery Pack. Subject to these Terms, including Article 5.4, a Card in the User's collection belongs to the User's account and may be kept in the collection, offered back to the Company through Buyback where available, or shipped to the User on request. 6. "Physical Item": The tangible trading card, sealed box, or memorabilia held by the Company or its partners that corresponds to a Card. 7. "Buyback": The optional transaction where the Company offers to purchase a Card back from the User in exchange for Points. ## Article 3. Eligibility and account 3.1. Eligibility The Service is limited to individuals who: * Are at least 18 years of age (or the age of majority in their jurisdiction). A minor may use the Service only with the prior consent of a parent or legal guardian, and any use by a minor is deemed to have such consent. * Have the legal capacity to enter into binding contracts. * Are not resident in a jurisdiction where the Service or gacha mechanics are prohibited by law. * Are not designated on any trade embargo or sanctions list. By registering an account, the User represents and warrants that all of the above criteria are met. 3.2. Account Responsibility The User is responsible for the confidentiality of login credentials and for all activity conducted through the account. Information provided, including shipping details, must be accurate and current. The Company is not liable for losses resulting from unauthorized use of the User's credentials or from inaccurate information provided by the User. 3.3. One Account Per Person Each User may hold only one account and shall not transfer, sell, lend, or share it. Where the Company reasonably determines that a User holds multiple accounts or has shared an account, it may suspend or close the accounts and cancel the associated Points, Gems, and delivery entitlements. 3.4. Registration Review The Company reserves the right to refuse registration or restrict access where it reasonably detects false information, automated registration, or abuse of promotions. 3.5. Regional Availability Specific features and payment methods depend on the User's location, applicable law, and the approval of the relevant payment providers, and may vary over time. The User shall not use a VPN, proxy, or any other means to disguise their true location or to circumvent regional restrictions. Access obtained through such means may be treated as a violation of these Terms. 3.6. Responsible Use The Company may apply spending or usage limits to any account and may offer self-exclusion or cooling-off tools on request through the support channel shown on the Service. ## Article 4. Cardz Game Points 4.1. Nature Cardz Game Points are a prepaid balance usable only within the Service as consideration for Mystery Packs and other designated features. Cardz Game Points have zero value. They have no cash value, no residual value, no redeemable value, and no independent market value. They are not cash, deposits, electronic money, stored value, securities, property, or any financial product, and do not bear interest. Cardz Game Points are non-refundable, non-withdrawable, and non-transferable, and cannot be exchanged for cash or any value outside the Service. Unused Cardz Game Points create no refund, payout, or withdrawal right. 4.2. Purchase Cardz Game Points may be purchased by Users located in Hong Kong, Macau, Japan, Taiwan, Malaysia, and Singapore through the payment methods shown in the Service. Purchase units, payment methods, and any applicable fees are displayed before the User confirms each purchase. 4.3. Finality Except where required by applicable law, all Cardz Game Points are final and non-refundable. Dissatisfaction with a Mystery Pack result, the market value of any Card, an unused balance, or a change of mind is not a ground for refund. The amount paid is fully earned by the Company upon completion of payment. A request for a refund, reversal, or chargeback after Cardz Game Points have been credited is a material breach of these Terms. 4.4. Display Units In certain regions outside those listed in Article 4.2, the Service may display balances and prices using the unit "USDC". The applicable purchase amounts and units are shown in the Service before confirmation. The display unit does not change the nature of the balance or create or alter any rights attached to it, including any withdrawal feature available in a specific region. 4.5. No Transfer Cardz Game Points may not be assigned, sold, lent, or otherwise disposed of to any third party, and may not be combined or moved between accounts. 4.6. Gems Gems may be used for designated Mystery Packs as shown in the Service. Cards obtained using Gems are not eligible for Buyback. Gems carry no cash value and are never withdrawable. 4.7. Records The User may review the balance and history in the Service. The Company's records constitute the authoritative record of balances. 4.8. Integrity Cardz Game Points or Gems obtained through fraud, payment reversal, a system error, exploitation of a system error, or any breach of these Terms may be cancelled. Where a payment provider reverses or refuses a completed purchase, the Company may deduct the corresponding Cardz Game Points and suspend related transactions. 4.9. Payment Providers The User's payments are processed by third-party payment providers under their own terms. Disputes regarding a payment provider's fees or processing are between the User and that provider. ## Article 5. Mystery Packs 5.1. Purchase Mystery Packs are purchased with Points, or with Gems where indicated. The required amount for each pack is displayed on the purchase page. 5.2. Allocation and Completion Each Mystery Pack draws from the disclosed pool for that pack. The Card is allocated to the User's collection at the moment the purchase is completed, and the opening animation is a presentation of the result already allocated. Once a pack offering is published, its pool and odds are fixed for that offering. Subject to Article 5.4, the Service is deemed fully performed when the Card is allocated to the User's collection, and the User has no right of withdrawal or cooling-off once a pack has been opened, without limiting any rights that cannot legally be excluded. 5.3. Final Sales Except where required by applicable law, and subject to Article 5.4, completed purchases are final and non-refundable, including purchases of Cardz Game Points, Mystery Pack purchases, and shipping fees. Mystery Pack purchases provide a randomized collectible experience. Marketing materials provide no guarantee that a particular Card will be allocated. A result that the User dislikes, a Card whose market value is lower than the amount spent, or any loss on a Mystery Pack does not constitute a defect, a failure of performance or grounds for a refund, reversal or chargeback. 5.4. Errors The Company may correct any pricing, inventory, description, probability, pool, allocation, configuration, display, processing, balance, communication, or technical error, including any error that results in a transaction, allocation, balance, communication, or delivery that does not match the Company's intended terms or records, whether discovered before or after payment, allocation, or a delivery request. The Company may cancel, limit, void, or reverse any affected order, allocation, Card, Buyback, balance change, or delivery request, including where it reasonably suspects fraud or payment failure, and may remove the affected Card from the User's collection. The User is not entitled to retain any Card, Physical Item, Points, Gems, or other benefit obtained as a result of such an error. If the User knew, or reasonably should have known, that a price, allocation, balance, or result was in error, the Company may treat the affected transaction as void. Where an affected transaction is voided or reversed, the Company will, at its discretion, restore the Points or Gems expended on that transaction, or require payment of the correct amount if the User elects to keep a correctly priced result. If a delivery request is cancelled under this Article before dispatch, any shipping fee paid for that request will be refunded. Title to a Physical Item does not pass while the related Card is subject to correction under this Article. Displays, screenshots, emails, chat messages, and automated notices do not create title or any right to retain an erroneous result. The Company's records prevail. A delay in discovering or correcting an error, or any communication concerning it, does not waive the Company's rights under this Article. The Company may pause purchases, deliveries, and Buybacks on the affected account while it reviews the error. If a Physical Item affected by an error has already been dispatched, the User shall return it on the Company's request. If it is not returned, the Company may recover the intended price or the item's value as shown in the Company's records, including by deducting Points, cancelling other Cards, reversing a related Buyback, and recovering costs. Restoration of the Points or Gems expended, or a refund of a shipping fee paid for a cancelled pre-dispatch request, is the User's sole remedy for an error under this Article. 5.5. Records In the event of any inconsistency between the value, name, and image shown for a result, or between any communication and the Company's records, the Company's records shall prevail. 5.6. Fulfillment Issues If the Company is unable to deliver the Physical Item corresponding to an allocated Card for any reason, the Company may, at its discretion, provide a substitute remedy, such as a comparable item or a Points credit, and such remedy shall be the User's sole remedy for the affected result. ## Article 6. Probabilities and fairness 6.1. Random Outcomes The outcome of any Mystery Pack is determined by a random number generator. The Company maintains internal controls designed to prevent any person, including Company staff, from predicting or influencing the result allocated to any User, and maintains records sufficient to demonstrate the integrity of results. Results are based purely on chance. 6.2. Probability Disclosure The potential contents of each Mystery Pack and the probability of obtaining each rarity tier, together with the corresponding value ranges, are displayed on the purchase page. * Variance: Stated probabilities are calculated over a large sample size and may not reflect the outcome of a small number of draws. * No Guarantee of Value: The market value of the Physical Item associated with a result may be lower than the cost of the Mystery Pack. The User assumes this risk. ## Article 7. Your collection 7.1. Ownership of Results Subject to Article 5.4, Cards in the User's collection belong to the User's account. The User may keep them, offer them back through Buyback where available, or request physical delivery at any time. There is no time limit for keeping Cards in the collection, and the Company does not charge for holding them. 7.2. Physical Delivery Subject to Article 5.4, legal title and risk in a Physical Item pass to the User upon dispatch of the item to the shipping carrier following a delivery request. Until dispatch, Physical Items remain the property of the Company. 7.3. Account Closure If the User closes the account, the User should request delivery of any Cards beforehand. If the Company terminates the account for a violation of these Terms, Cards and Points obtained in connection with the violation may be cancelled. In all other cases of termination, the User may request delivery of remaining Cards within thirty (30) days of termination, subject to Article 8. 7.4. Service Changes and Wind-Down The Company may modify, suspend, or discontinue the Service or any feature at its discretion. If the Company discontinues the Service entirely, it will provide reasonable advance notice, and Users may request delivery of Cards in their collection during the notice period, subject to Article 8. Points remain subject to Article 4.3 and are not refundable upon discontinuation. ## Article 8. Shipping and delivery 8.1. Delivery Requests Users may request physical delivery of their Cards through the Service. The Company may require identity verification and the resolution of any outstanding payment dispute before releasing items for shipment. The Company may refuse, hold, or cancel a delivery request for any Card that is or may be affected by Article 5.4, including after the request has been submitted and before dispatch. Shipping fees are non-refundable once processing has begun, except as provided in Article 5.4. Processing, dispatch, transit and arrival dates or periods shown in the Service, order updates or support communications are estimates. The Company provides no guaranteed deadline or maximum waiting period on the basis of an estimate. Actual fulfillment may take longer. Estimates may be revised because of request volume, item preparation, required account or payment checks, carrier availability, destination conditions or customs clearance. An order acknowledgement, delivery request, tracking update or payment of shipping fees provides no delivery-date guarantee by itself. Expressly agreed delivery commitments and any deadline, cancellation right or other remedy required by applicable law remain applicable. 8.2. Shipping Fees Shipping fees are calculated at the time of the request based on destination, weight, volume, and applicable surcharges, and are displayed before confirmation. Shipping fees are payable using the options shown for the delivery request. Under the Social Sharing Reward free-shipping campaign, Points (PTS) credited following manual approval may be used to pay card delivery fees, subject to that campaign's requirements. Users should wait for the approved PTS to be credited before paying shipping fees or submitting the delivery request. This campaign does not authorize shipping payment with Gems and does not imply coverage of duties, taxes or other charges. An application or sharing post does not itself constitute approval, crediting of PTS or a refund of previously paid shipping fees. See the FAQ and Shipping & Delivery Policy for the application process. The Company may consolidate multiple delivery requests from the same User into a single shipment. 8.3. Duties and Taxes Unless otherwise shown at checkout, shipments are sent with destination duties and taxes unpaid by the Company. The User is the importer of record and is responsible for all import taxes, duties, and clearance fees. If a package is returned because the User declined these charges or provided an invalid address, the shipping fee is forfeited and no Points refund will be issued. 8.4. Delivery Risk Title and risk of loss pass to the User upon dispatch to the carrier. Shipments include tracking. Once dispatched, responsibility for any loss, delay, or damage in transit rests with the carrier. The Company will provide reasonable assistance with carrier claims where available, and any recovery is limited to the amount actually recovered from the carrier. The Company is not liable for packages lost, delayed, or damaged in transit. 8.5. Delivery Issues The User should contact the Company through the support channel shown on the Service to report a damaged shipment within seven (7) days of delivery, with photographs of the packaging and contents. The User agrees to preserve the packaging and to cooperate with any carrier claim. 8.6. Address Errors If the Company cannot ship due to an incomplete or inaccurate address, or a package is returned due to an address error, absence, or refusal of receipt, and the matter is not resolved within thirty (30) days of the original delivery request, the corresponding Card is cancelled without compensation. 8.7. Condition on Arrival For sealed boxes, minor case or shrink-wrap imperfections are not eligible for exchange. To request an exchange for a suspected re-sealed box, the User must provide an unedited video of the unboxing. ## Article 9. Buyback 9.1. Nature The Company may, at its sole discretion, offer to purchase a Card back from the User in exchange for Points. Buyback is a separate, optional transaction available only after the User holds the Card. Buyback creates no payout, refund or return entitlement in respect of a prior purchase. Offers are discretionary and time-limited as shown at the time of the offer. The User is never obligated to accept. Cards obtained using Gems are not eligible for Buyback. 9.2. Pricing Buyback prices are dynamic and determined by the Company based on market data, comparable sales, inventory levels, and other internal considerations. There is no guaranteed buyback ratio, and offer prices may differ significantly from the amount originally paid. 9.3. Settlement Buyback proceeds are credited to the User's account balance in the unit shown at the time the offer is made. Settlement of a Buyback does not create any withdrawal right beyond what the User's balance already carries under Article 4. 9.4. Availability The Buyback feature is not guaranteed. The Company may disable it during periods of high volatility, decline specific Cards, or limit volumes per User. ## Article 10. Withdrawals 10.1. Limited Availability A withdrawal feature may be offered to Users in certain regions outside those listed in Article 4.2, for balances originally purchased in those regions, through the networks shown in the Service. Availability, supported networks, minimums, and any applicable fees are as displayed in the Service from time to time and may change. Points, Gems, Buyback proceeds, and any balance derived from them are never withdrawable. 10.2. Review and Holding Withdrawals are subject to identity verification and security review. Only balances that have been used at least once for a transaction within the Service are eligible for withdrawal. The Company may apply a holding period before processing any withdrawal, and may delay, refuse, or cancel a withdrawal where it reasonably suspects fraud, abuse, payment disputes, or any breach of these Terms. 10.3. User Responsibility The User is solely responsible for the accuracy of withdrawal destination details and the security of the destination account. Completed withdrawals are irreversible. The Company is not liable for losses resulting from incorrect destination details, compromised accounts, or failures of third-party networks or providers. ## Article 11. Prohibited conduct The User agrees not to engage in any of the following: 1. Market manipulation, wash trading, or collusion related to the Service. 2. Use of bots, scrapers, emulators, or modified client software, or reverse-engineering of the Service. 3. Knowingly exploiting bugs, glitches, logic errors, or other errors for an unfair advantage, including requesting delivery of Cards the User knows or reasonably should know were obtained in error. 4. Abuse of pack mechanics, promotions, or new-user offers, as reasonably determined by the Company. 5. Money laundering or use of the Service to obscure the source of funds. 6. Accessing the Service from a jurisdiction subject to comprehensive sanctions. 7. Payment Disputes: initiating a refund request, reversal, chargeback, or payment dispute after Cardz Game Points have been credited or after a Mystery Pack result has been allocated. The User agrees to contact the Company through the support channel shown on the Service first so the Company has the opportunity to resolve the issue. Because a Mystery Pack is, subject to Article 5.4, performed in full when the result is allocated, disputing a completed purchase after receiving the result is a breach of these Terms. The Company will contest such claims. While any payment dispute is being reviewed, the Company may pause the affected account's purchases, deliveries, and other transactions, and may recover amounts associated with a reversed payment, including by deducting the corresponding Points, cancelling results obtained with them, and recovering chargeback fees, collection costs, and legal fees. The Company may pursue the User for those sums. The Company will provide transaction, allocation, account, and delivery records to the payment provider, and may provide those records to card networks, banks, collection agents, and competent authorities. 8. Publishing false information about the Service, or harassment, threats, or defamation toward the Company, its staff, or other Users. 9. Selling, transferring, or sharing an account, or accessing another User's account. 10. Using automated purchasing systems or agents. Consequences: Violation of this Article may result in suspension or termination of access, freezing of pending transactions, and cancellation of Points and Cards obtained in connection with the violation, in each case to the extent permitted by applicable law. The Company may also pursue the User for losses, fees, and legal costs arising from the violation. ## Article 12. Grading and condition All Physical Items are sourced through established distribution channels and inspected prior to listing. * Graded Cards: The Company relies entirely on the certification of third-party grading authorities (PSA, BGS, CGC, etc.) and makes no independent representation regarding the accuracy of grades. Minor imperfections on a grading case are not grounds for exchange. * Raw Cards: Condition assessments for ungraded cards are subjective opinions of the Company's staff, and a specific grading outcome is not guaranteed. * Sealed Products: Sealed products are sourced through partner stores and inspected by the Company. The exchange remedy in Article 8.7 applies to suspected re-sealed products. * Authenticity: If a Physical Item supplied by the Company is conclusively determined to be counterfeit by the original grading or authentication provider, the Company will refund the purchase price upon return of the item. This refund is the sole and exclusive remedy for a confirmed counterfeit determination and does not apply to disputes regarding condition, grading outcomes, or market value. ## Article 13. Disclaimers 13.1. "As Is" Basis The Service is provided on an "as is" and "as available" basis without warranties of any kind, whether express or implied, including accuracy, reliability, merchantability, fitness for a particular purpose, and non-infringement. 13.2. Service Interruption The Company may suspend all or part of the Service without prior notice for maintenance, system failure, network disruption, natural disaster, requests from public authorities, or operational necessity, and shall not be liable for any resulting disadvantage, except in cases of the Company's willful misconduct or gross negligence. 13.3. Force Majeure The Company shall not be responsible for any delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, epidemics, government actions, utility or network failures, and failures of carriers or suppliers. 13.4. No Investment Advice Cards and Physical Items are collectibles offered for entertainment and collecting purposes. Nothing in the Service constitutes investment, financial, appraisal, or tax advice, and no representation is made regarding the present or future market value of any item. ## Article 14. Limitation of liability and indemnification 14.1. General Limitation To the maximum extent permitted by applicable law, the Company, its affiliates, directors, and employees shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, data, or goodwill. 14.2. Monetary Cap In the event the Company is found liable for damages (excluding willful misconduct or gross negligence), the Company's total cumulative liability shall not exceed the total amount actually paid by the User to the Company in the transaction giving rise to the claim. 14.3. Indemnification The User agrees to indemnify and hold harmless the Company, its affiliates, directors, and employees from and against any claims, damages, losses, and expenses (including reasonable legal fees) arising out of the User's violation of these Terms, misuse of the Service, refund or chargeback activity, or infringement of any third-party rights. 14.4. Assumption of Risk The User acknowledges and assumes the risks inherent in randomized purchase mechanics and the price volatility of collectibles, including that the User may receive a Card worth less than the amount spent. ## Article 15. Promotions and giveaways From time to time the Company may run campaigns, competitions, or giveaways. Each promotion is governed by its own official rules in addition to these Terms. Gems and other promotional credits are subject to the rules of the applicable promotion and carry no cash value. The Company may modify, suspend, or cancel any promotion where reasonably necessary, and may disqualify entries that violate these Terms. Employees of the Company and its affiliates, and members of their immediate households, are not eligible to participate in promotions or giveaways and are not eligible for Buyback. ## Article 16. Unlawful organizations The User represents and warrants that they are not a member of, or affiliated with, any criminal or unlawful organization, and that they do not provide funds or cooperation to such organizations. The Company may immediately terminate the agreement in case of breach of this Article, or of violent or threatening behavior toward the Company or its staff. ## Article 17. Governing law and disputes 17.1. Governing Law These Terms are governed by the laws of the jurisdiction in which the Company is incorporated, without regard to conflict of law principles. 17.2. Jurisdiction Disputes arising out of or in connection with these Terms shall be submitted to the exclusive jurisdiction of the courts of the jurisdiction in which the Company is incorporated, except where mandatory applicable law provides otherwise. 17.3. Individual Claims To the maximum extent permitted by applicable law, all claims and disputes must be brought on an individual basis only, and not as a plaintiff, claimant, or class member in any class, collective, consolidated, or representative action or proceeding. The User waives any right to participate in any such class, collective, consolidated, or representative action against the Company, except where such waiver is prohibited by applicable law. 17.4. Consumer Rights Nothing in these Terms excludes, restricts, or modifies any consumer right or remedy that cannot lawfully be excluded, restricted, or modified under the laws applicable to the User. ## Article 18. General 18.1. Entire Agreement These Terms, together with the policies and rules referenced in them, constitute the entire agreement between the User and the Company regarding the Service and supersede all prior or contemporaneous statements, whether written or oral. 18.2. Assignment The Company may assign or transfer its rights and obligations under these Terms, in whole or in part, including in connection with a merger, reorganization, or sale of assets. The User may not assign or transfer these Terms without the Company's prior written consent. 18.3. Severability and Waiver If any provision of these Terms is held invalid or unenforceable, the remaining provisions shall continue in full force and effect. The failure of the Company to enforce any right or provision shall not be deemed a waiver. 18.4. Language These Terms may be made available in languages other than English for convenience. In the event of any inconsistency, the English version prevails. ## Article 19. Contact For inquiries regarding these Terms, the User may contact the operator of the Service at: * Email:
