Terms of Use

Effective Date: May 11, 2026 · Last Updated: May 11, 2026

These Terms of Use (the “Terms”) form a binding agreement between you (“you” or “User”) and MINER TYCOON LIMITED (“Company”, “we”, “our”, or “us”) governing your access to and use of the TCGCardsVault mobile application (the “App”) and any related services we provide (collectively, the “Services”).

By downloading, installing, accessing, or using the App, you agree to be bound by these Terms and by our Privacy Policy, which is incorporated by reference. If you do not agree, do not use the App.

1. Eligibility

You must be at least 13 years old (or the minimum age of digital consent in your jurisdiction, whichever is higher) to use the App. By using the App you represent and warrant that you meet this age requirement and that you have the legal capacity to enter into these Terms. If you are using the App on behalf of an organization, you represent that you are authorized to bind that organization to these Terms.

2. Account & Device Identity

The App identifies you by a randomly generated account UUID derived from a stable device identifier. We do not require traditional account credentials such as a username, email, or password. You are responsible for maintaining the security of the device on which the App is installed. Any activity occurring under your installation is your responsibility.

If you uninstall the App, transfer your device, or reset your device identifier, you may lose access to your portfolio data unless it has been backed up through a Restore Purchases flow or other supported mechanism.

3. License & Acceptable Use

Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the App on devices you own or control, for your personal, non-commercial use.

You agree not to, and not to permit any third party to:

• Reverse engineer, decompile, disassemble, or attempt to derive the source code or underlying ideas of the App, except to the extent such restriction is prohibited by applicable law.
• Modify, adapt, translate, or create derivative works of the App.
• Remove, alter, or obscure any proprietary notices in the App.
• Use the App in any manner that could damage, disable, overburden, or impair our servers or networks.
• Access the App or its underlying APIs through automated means, scrapers, or bots without our written permission.
• Use the App to send spam, malware, or any unlawful content.
• Misrepresent your identity or affiliation with any person or entity.
• Attempt to circumvent any usage limits, subscription requirements, or security mechanisms.
• Resell, lease, sublicense, or commercially exploit the App or its content.

4. Subscriptions & Payments

4.1 Pro Subscription

The App offers an optional paid subscription (“Pro”) that unlocks advanced features such as unlimited price alerts, advanced analytics, bulk card scanning, and additional capabilities listed within the App. Pro is available as weekly, monthly, and annual auto-renewing subscriptions at the prices displayed within the App. Prices are localized to your store region and are inclusive of any applicable taxes where required.

4.2 Billing

All subscription purchases are processed by Apple via App Store In-App Purchase or by Google via Google Play Billing. We do not handle your payment information. Your purchase, renewal, refund, and cancellation rights are governed by the applicable store’s terms in addition to these Terms.

4.3 Auto-Renewal

You can manage and cancel subscriptions at any time in your device’s store account settings:

• iOS: Settings > [Your Name] > Subscriptions
• Android: Google Play app > Profile > Payments & subscriptions > Subscriptions

4.4 Free Trials

Where a free trial is offered, you will not be charged during the trial period. If you do not cancel before the trial ends, your subscription will automatically convert to a paid subscription at the displayed rate. Free trials may not be available in all regions or to users who have previously redeemed a trial.

4.5 Refunds

All subscription purchases are final and non-refundable except as required by applicable law or by the policies of Apple or Google. Refund requests must be submitted directly to the applicable store. We do not process refunds directly.

4.6 Price Changes

We may change subscription prices from time to time. Where required by law, we will notify you in advance and obtain your consent to a renewal at the new price before charging you.

5. Pricing Data & Card Information

The App displays card prices, market trends, and similar collectibles data sourced from third-party catalogs and marketplaces. This data is provided for informational purposes only. It is not investment advice, appraisal, or a guarantee of resale value. Prices fluctuate constantly and may be inaccurate, delayed, or unavailable. You should independently verify any information before making purchase, sale, or trade decisions.

Card images, names, set codes, rarities, and other catalog metadata may be trademarks or copyrights of their respective owners. The App uses such material for informational purposes under fair use and does not claim ownership.

6. Card Scanning & User Content

The App allows you to scan physical cards via your device camera or photo library. By submitting an image, you grant us a non-exclusive, royalty-free license to process the image solely to perform optical character recognition (OCR) and return matching catalog entries. Submitted images are processed in transient storage and are not retained after recognition completes.

You represent that you have all necessary rights to any image you submit and that doing so does not violate any law or any third party’s rights.

7. Notifications

If you enable push notifications, we may send you alerts you have configured (such as price alerts) and occasional service announcements. You may opt out at any time from your device’s system settings or the App’s notification settings screen. Opting out of marketing notifications does not opt you out of transactional notifications (such as subscription receipts) where applicable.

8. Intellectual Property

All rights, title, and interest in and to the App, including all associated software, designs, logos, trademarks, service marks, trade names, and content (excluding User Content and third-party catalog data), are owned by MINER TYCOON LIMITED or our licensors and are protected by copyright, trademark, and other intellectual property laws. Nothing in these Terms grants you a right to use any trademark, logo, or service mark of MINER TYCOON LIMITED without our prior written consent.

9. Third-Party Services

The App integrates with third-party services including Apple App Store, Google Play, Firebase, RevenueCat, and Singular. Your use of those services is governed by the respective third-party terms and privacy policies. We are not responsible for the availability, accuracy, or content of third-party services.

10. Disclaimers

THE APP AND SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, OR NON-INFRINGEMENT.

We do not warrant that the App will be uninterrupted, secure, error-free, or that defects will be corrected. We do not warrant the accuracy, completeness, reliability, or timeliness of any catalog data, pricing data, or other content displayed in the App. You assume all risk arising from your use of the App.

11. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL MINER TYCOON LIMITED, ITS OFFICERS, DIRECTORS, EMPLOYEES, OR AGENTS BE LIABLE TO YOU FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES (INCLUDING DAMAGES FOR LOSS OF PROFITS, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES) ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF, OR INABILITY TO USE, THE APP, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR AGGREGATE LIABILITY TO YOU FOR ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS OR THE APP SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO US FOR THE APP IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) USD $50.00.

Some jurisdictions do not allow the exclusion or limitation of certain warranties or damages, so some of the above limitations may not apply to you.

12. Indemnification

You agree to indemnify, defend, and hold harmless MINER TYCOON LIMITED and its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses, including reasonable attorneys’ fees, arising out of or in any way connected with: (a) your access to or use of the App; (b) your violation of these Terms; (c) your violation of any third-party right; or (d) any content you submit through the App.

13. Termination

We may suspend or terminate your access to the App at any time, with or without cause and with or without notice, including if we reasonably believe you have violated these Terms. You may stop using the App at any time by uninstalling it. Sections that by their nature should survive termination shall survive, including Sections 8 (Intellectual Property), 10 (Disclaimers), 11 (Limitation of Liability), 12 (Indemnification), 14 (Governing Law), and 15 (Dispute Resolution).

Termination does not entitle you to a refund of any subscription fees already paid except where required by applicable law.

14. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Hong Kong Special Administrative Region, without regard to its conflict-of-laws principles. Apple App Store users in the European Union may have additional rights under EU law that are not affected by this clause.

15. Dispute Resolution

Any dispute, controversy, or claim arising out of or relating to these Terms or the App shall first be addressed through good-faith negotiation between the parties. If the dispute cannot be resolved within thirty (30) days of written notice, it shall be submitted to the competent courts of the Hong Kong Special Administrative Region, unless mandatory law in your jurisdiction provides otherwise.

Class action waiver: To the fullest extent permitted by applicable law, you and we agree that each may bring claims against the other only in your or our individual capacity and not as a plaintiff or class member in any purported class or representative proceeding.

16. Apple App Store Additional Terms

If you obtained the App through the Apple App Store, the following additional terms apply:

• These Terms are between you and MINER TYCOON LIMITED only, and not with Apple. Apple is not responsible for the App or its content.
• The license granted to you for the App is limited to a non-transferable license to use the App on Apple-branded products you own or control, subject to the Apple Media Services Terms and Conditions.
• Apple has no obligation to provide maintenance or support for the App.
• In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the App purchase price to you (where applicable). To the maximum extent permitted by law, Apple has no other warranty obligation.
• Apple is not responsible for addressing any claims by you or any third party relating to the App, including product liability, regulatory compliance, or consumer protection claims.
• If a third party claims the App infringes its intellectual property rights, MINER TYCOON LIMITED, not Apple, is responsible for handling that claim.
• Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms with respect to your license to use the App and may enforce these Terms against you.

17. Google Play Additional Terms

If you obtained the App through Google Play, your use is also subject to the Google Play Terms of Service. Google is not a party to these Terms and is not responsible for the App.

18. Modifications to the App or Terms

We may modify, suspend, or discontinue any aspect of the App at any time without liability to you. We may also amend these Terms from time to time. When we do, we will update the “Last Updated” date above. Material changes will be communicated through the App or by other appropriate means. Your continued use of the App after the effective date of any change constitutes your acceptance of the updated Terms.

19. Miscellaneous

Entire Agreement. These Terms, together with the Privacy Policy and any store-specific terms, constitute the entire agreement between you and us regarding the App.

Severability. If any provision of these Terms is held invalid or unenforceable, the remaining provisions will continue in full force and effect.

No Waiver. Our failure to enforce any right or provision shall not constitute a waiver of that right or provision.

Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms at any time without notice.

Notices. Notices to you may be delivered through the App or via email if we have one for you. Notices to us must be sent to the contact address below.
