9. User-Generated Content

The Service may allow users to create, upload, generate, or share content, including decklists, comments, images, collection data, profile information, card notes, and other materials.

This is referred to as “User Content”.

By submitting User Content, you confirm that:

You own it or have permission to use and publish it
It does not violate the rights of others
It does not break the law
It does not contain harmful, abusive, misleading, or prohibited material

You keep ownership of your User Content.

By submitting User Content, you grant the Owner a non-exclusive, worldwide, royalty-free license to host, store, display, process, and use that content only as needed to operate, improve, protect, and provide the Service.

Some User Content, such as public decklists, usernames, profile information, comments, or shared pages, may be visible to other users or visitors depending on your settings and the features you use.

The Owner may remove, restrict, or moderate User Content where reasonably necessary, including when content appears to violate these Terms, third-party rights, applicable law, or the integrity of the Service.

10. Account Registration and Account Security

Some features may require an account.

When creating an account, you agree to provide accurate and up-to-date information.

You are responsible for keeping your login credentials safe and for activity that occurs under your account.

If you believe your account has been accessed without permission, please contact the Owner as soon as possible at:

contact@mtgmaster.ai

You may stop using the Service at any time. If you want to request account deletion or exercise data protection rights, please contact the Owner or follow the instructions provided in the Privacy Policy.

11. AI Features and Outputs

MTG Master may include AI-powered features to help with deck analysis, recommendations, explanations, summaries, optimization ideas, and other gameplay or collection-related tools.

These features are designed to support deck-building decisions and make Commander analysis easier, faster, and more useful.

AI results should be understood as helpful guidance based on the information available to the Service, including the decklist, selected bracket, available card data, and the context provided by the user.

Because Commander games depend on playgroup expectations, local meta, budget, card availability, and personal preferences, users should review suggestions and decide what works best for their own decks.

MTG Master is not an official Magic: The Gathering rules authority and does not replace official Wizards of the Coast resources for official rules, tournament policy, card legality, or official card text.

Additional details may be provided in the AI Use & Limitations Policy.

12. Digital Purchases, Credits, and Subscriptions

The Service may offer paid digital features, including credits, subscriptions, premium access, AI tools, or other Pro Features.

Before completing a purchase, the Service will display the relevant price, taxes where applicable, and the main conditions of the purchase.

By purchasing paid features, you agree to:

Pay the displayed price, including applicable VAT when required
Use the selected third-party payment provider, such as Stripe
Follow any usage limits, credit rules, or subscription conditions shown before purchase
Provide accurate billing and payment information

Digital credits and paid features may be delivered or made available immediately after purchase.

Where required by applicable consumer law, you may be asked to expressly consent to immediate access to the digital service and acknowledge that you may lose your right of withdrawal once execution begins or once digital content has been supplied.

This does not affect any mandatory consumer rights that apply under Spanish or EU law.

Because digital services and credits may be consumed immediately, refunds are generally not available once the purchased service has been delivered or credits have been used, except where required by applicable law or where the Owner decides to offer a refund at their discretion.

If you believe there has been an error with a payment, credit balance, subscription, or purchase, please contact:

contact@mtgmaster.ai

13. Data Protection

Personal data is processed in accordance with applicable data protection laws, including:

Regulation (EU) 2016/679, the General Data Protection Regulation
Spanish Organic Law 3/2018 on Data Protection and Digital Rights Guarantee

Details about what data is collected, why it is collected, how it is used, legal bases, retention periods, security measures, and user rights are explained in the Privacy Policy.

14. Third-Party Services and Links

The Service may include links to external websites or use third-party services, such as payment providers, card data providers, analytics providers, hosting services, or authentication tools.

These third-party services are operated by independent providers.

The Owner is not responsible for the content, availability, accuracy, policies, or practices of third-party websites or services.

Use of third-party services may be subject to their own terms and privacy policies.

15. Availability, Changes, and Maintenance

The Owner works to keep the Service available and useful, but uninterrupted access cannot be guaranteed.

The Service may occasionally be unavailable, limited, modified, or interrupted due to maintenance, updates, technical issues, third-party provider problems, security needs, or other reasons.

The Owner may improve, change, suspend, or discontinue parts of the Service over time.

Where a significant change affects paid features, the Owner will take reasonable steps to communicate the change clearly.

16. Disclaimers

To the maximum extent permitted by applicable Spanish and EU law, the Service is provided on an “as is” and “as available” basis.

The Owner does not guarantee that:

The Service will always be available, uninterrupted, secure, or error-free
Card data, pricing data, or third-party information will always be accurate or up to date
AI-generated outputs will always be correct, complete, or suitable for your needs
Deck recommendations will produce any specific result in games or tournaments
Bugs, errors, or compatibility issues will never occur

MTG Master is not an official Magic: The Gathering rules authority. For official rules, tournament policy, card legality, and official card text, users should consult official Wizards of the Coast resources or other recognized official sources.

17. Limitation of Liability

Nothing in these Terms limits or excludes liability where such limitation or exclusion is not permitted under applicable law, including mandatory consumer protection rights.

To the maximum extent permitted by Spanish and EU law, the Owner is not liable for indirect, incidental, special, punitive, or consequential damages, including loss of profits, data, goodwill, opportunities, or business interruption.

If you are dissatisfied with the Service, you may stop using it. If you have purchased paid features, any rights or remedies available to you under applicable consumer law remain unaffected.

Where a limitation of liability is legally allowed and applies, the Owner’s total cumulative liability will be limited to the amount paid by you for the affected paid feature during the twelve months before the event giving rise to the claim, or €100, whichever is higher.

18. User Responsibility

You are responsible for how you use the Service, including any decisions you make based on deck analysis, AI recommendations, card prices, collection data, or other information provided through the Service.

You are also responsible for ensuring that your use of the Service complies with applicable laws, these Terms, and any relevant third-party rules or policies.

19. Misuse and Responsibility for Harm

If you misuse the Service, violate these Terms, infringe third-party rights, or cause harm to the Service, the Owner, or other users, you may be responsible for the losses caused, where permitted by applicable law.

This section is intended to apply only to situations where responsibility can lawfully be attributed to you.

20. Governing Law and Jurisdiction

These Terms are governed by the laws of Spain and applicable EU regulations.

If you are a consumer, you benefit from any mandatory protections and rights provided by the laws of your place of residence.

Unless mandatory consumer law states otherwise, disputes will be submitted to the courts of the Owner’s domicile.

21. Severability

If any part of these Terms is found to be invalid or unenforceable, the remaining parts will continue to apply.

Where possible, the invalid or unenforceable part will be replaced by a valid provision that most closely reflects the original purpose.

22. No Waiver

If the Owner does not enforce a provision of these Terms immediately, this does not mean the Owner waives the right to enforce it later.
