Terms of Service

Silvane is open to Magic players everywhere, with a few basic requirements. You must be at least 13 years old — or older, if your country sets a higher minimum age for using online services. If you are under 18, or under the age of majority where you live, you may use Silvane only with the involvement of a parent or guardian.

If you use the Service for a company or other organization, you confirm that you are authorized to accept these Terms on its behalf. By using the Service, you confirm that you meet these requirements.

Purchases require the age of majority: if you are a minor, a parent or guardian must make or approve any purchase on your behalf.

Some features require an account. You can sign in with an email address or through a third-party provider such as Google or Apple. You are responsible for keeping your login credentials secure and for all activity that happens under your account. Provide accurate information, keep it up to date, and let us know promptly at support@silvane.app if you believe your account has been accessed without your permission.

You may browse limited parts of the Service as a guest, but guest data may not be recoverable if you do not create an account. One account is intended for one person; do not share your account or let others use it in a way that violates these Terms.

Silvane is built to organize what you own and want. The data you add — your collections, binders, decks, lists, wants, cards for trade, quantities, prices you paid, notes, tags, and similar information (“Your Content”) — belongs to you. We do not claim ownership of Your Content.

To operate the Service, you grant us a limited, non-exclusive, worldwide, royalty-free license to host, store, back up, reproduce, process, and display Your Content solely as needed to provide Silvane to you — including syncing it across your devices and, where you choose to share, making the relevant items visible to others. This license exists only to run and improve the Service and ends when you delete Your Content or your account, except for reasonable residual backups and anything you have already shared publicly.

You are responsible for Your Content and for having the rights to it. You can export or delete your data as described in our Privacy Policy. Items you delete inside the app go to a recycle bin for a limited period (currently about 30 days) so you can restore them; after that they are permanently removed.

Silvane lets you share binders, decks, lists, saved views, and your profile — including your “For Trade” and “Wants” pages — through public links. When you make an item public, anyone who has the link can view it without signing in, and search engines may index public pages. You control what is public: each shareable item can be made private again, and you can hide sections of your public profile from your settings.

Please do not put anything in a shared name, note, or profile field that you would not want to be publicly visible.

We do not review, verify, or endorse content that other users choose to make public — deck or binder names, notes, or the cards they list for trade or as wanted. That content comes from those users, not from us, so please use your own judgment when relying on it.

Silvane helps you display the cards you have available for trade and the cards you are looking for. It is an organizational and informational tool only. We do not broker, facilitate, process, guarantee, or otherwise take part in any trade, sale, or other transaction between users. Any arrangement you reach with another person is solely between you and them, at your own risk. Always use your own judgment and verify the other party and the cards before you trade or buy.

Card names, text, images, set and mana symbols, and related metadata are sourced from Scryfall and other community sources. Pricing is aggregated from third-party and community sources and is provided for general informational purposes only.

All prices, valuations, trends, and totals shown in Silvane are estimates. They can be delayed, incomplete, or inaccurate, and they do not represent an offer to buy or sell. Nothing in the Service is financial, investment, or trading advice. Treat any value as a rough guide, and confirm current prices with a store or marketplace before you buy, sell, or trade.

Silvane offers features powered by artificial intelligence — for example the Rules Judge, which answers Magic rules questions (including from photos of the board), and AI-powered search. Some AI features are limited on the free plan or reserved for paid plans.

AI output can be inaccurate, incomplete, or out of date. Rules Judge answers are not official rulings and are no substitute for a certified judge or tournament ruling, and nothing in the Service is professional, financial, or legal advice. Always verify anything important before acting on it. You are responsible for how you use these features and their output.

Silvane provides a Model Context Protocol (MCP) endpoint that lets you connect AI assistants you already use — such as Claude or ChatGPT — to your own account. A client you authorize can read and, where you allow it, modify the data in your account on your behalf.

• Anything a client you have authorized does in your account counts as activity under your account, and these Terms apply to it;
• Your relationship with the AI provider you connect is governed by that provider’s own terms and privacy policy — we do not control what it does with the data it reads;
• Usage limits and plan quotas apply to connected clients the same way they apply in the app;
• You can revoke a client’s access at any time from that client’s settings, which stops further access;
• The MCP endpoint is part of the Service: we may change, limit, or discontinue it like any other feature.

You agree not to misuse the Service. In particular, you will not:

• Break any applicable law or regulation, or infringe anyone’s intellectual property or other rights;
• Upload or share content that is unlawful, harassing, hateful, abusive, deceptive, or otherwise objectionable, or impersonate any person or organization;
• Introduce viruses, malware, or any other harmful code, or attempt to probe, scan, breach, or circumvent the security or authentication of the Service;
• Access the Service with bots, scrapers, or other automated means beyond normal personal use, or copy, harvest, or index its data without our prior written consent;
• Interfere with, overburden, disrupt, or degrade the Service or the servers and networks behind it, or exceed rate or usage limits we may set;
• Reverse engineer, decompile, or attempt to extract source code from the Service, except to the limited extent this restriction is prohibited by applicable law;
• Resell, sublicense, frame, or otherwise commercially exploit the Service or any part of it without our permission.

We handle violations case by case and may take any action we consider appropriate, from a warning to removing content or suspending or terminating your access.

Magic: The Gathering content. Silvane is an independent, unofficial fan project. It is not affiliated with, endorsed, sponsored, or approved by Wizards of the Coast LLC or Hasbro, Inc. Magic: The Gathering, card names and artwork, mana and set symbols, and the related logos and marks are trademarks of and copyrighted by Wizards of the Coast (© 1993–present, all rights reserved). Silvane displays that material to help you manage your own collection, as permitted under Wizards’ Fan Content Policy; all rights in it remain with Wizards.

Silvane’s property. The Silvane name and logo, the website and apps, and their design, text, graphics, and software are owned by us or our licensors and are protected by intellectual property laws. Subject to these Terms, we grant you a personal, revocable, non-exclusive, non-transferable license to use the Service for its intended purpose. We may limit, suspend, or revoke that license at any time. You may not copy, modify, distribute, or create derivative works from the Service except as these Terms allow or as we authorize in writing. All rights not expressly granted are reserved.

The Service depends on and links to services provided by others — including Scryfall for card data, sign-in providers such as Google and Apple, cloud hosting and sync infrastructure, and the Apple App Store and Google Play. Your use of those services is governed by their own terms and privacy policies. We do not control third-party services or content and are not responsible for them.

If you download our app from the Apple App Store or Google Play, you also agree to that store’s terms. Where required by Apple, you acknowledge that these Terms are between you and Silvane and not Apple; that Apple has no obligation to provide support for the app; and that Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them.

Silvane offers a free plan with limited usage and a paid subscription — Silvane Pro — that unlocks higher limits and additional features, available monthly or annually. What each plan includes and its current price are always shown before you buy.

Billing. Subscriptions are purchased in the app and billed exclusively through your Apple App Store or Google Play account under that store’s terms. Silvane does not process payments and never receives your card details. Prices may vary by country and may exclude taxes the store applies.

Auto-renewal and cancellation. Subscriptions renew automatically at the end of each billing period unless you cancel at least 24 hours before renewal. You cancel in your App Store or Google Play subscription settings — deleting the app, or your Silvane account, does not cancel a store subscription. After you cancel, Pro stays active until the end of the period you already paid for.

Refunds. Because billing runs through the app stores, refunds are handled by Apple or Google under their policies; we cannot issue refunds for store purchases ourselves. Nothing here limits any non-waivable refund rights you have under the law where you live.

If your subscription ends. When Pro expires or is canceled, your account returns to the free plan. Your data is not deleted — but free-plan limits apply again: Pro-only features stop working, and you may not be able to add new items beyond the free limits until you make room or resubscribe.

Changes. We may change subscription prices or what each plan includes. If a price increase affects an active subscription, you will be notified in accordance with the applicable store’s rules and can cancel before it takes effect. If we offer free trials or promotional pricing, their specific terms will be shown before you accept them.

We are actively developing Silvane. We may add, change, suspend, or discontinue features (including experimental or beta features) at any time, and we may set or adjust limits on use. We will try to avoid disruption, but we are not liable to you for changes to or the discontinuation of any feature.

You can stop using Silvane at any time, and you can delete your account from within the app. When you delete your account, we remove your personal data as described in our Privacy Policy; items you shared publicly may persist for a time in cached or anonymized form that no longer identifies you. Deleting your account does not cancel an active subscription — manage or cancel it in your App Store or Google Play settings, or the store may keep billing you.

We may suspend or end your access if you break these Terms, if we reasonably believe it is necessary to protect the Service or other people, or if the law requires it. If we end your access for a breach of these Terms, you are not entitled to a refund, except where the law requires one (store purchases remain subject to the store’s refund policies). When your access ends, the license we grant you ends with it. Sections that by their nature should continue — such as intellectual property, disclaimers, limitation of liability, and indemnification — survive termination.

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied. To the maximum extent permitted by law, we disclaim all implied warranties, including merchantability, fitness for a particular purpose, and non-infringement.

We do not warrant that the Service will be uninterrupted, secure, or error-free, that defects will be corrected, or that any card data, prices, or other information will be accurate, complete, or current. You use the Service at your own risk.

To the maximum extent permitted by law, Silvane and its operators will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, data, goodwill, or cards, arising out of or relating to your use of — or inability to use — the Service, even if we have been advised of the possibility of such damages.

To the extent any liability is not excluded, our total liability for all claims relating to the Service is limited to the greater of the amount you paid us for the Service in the twelve months before the claim, or US $100. Your sole and exclusive remedy for dissatisfaction with the Service is to stop using it. Any claim relating to the Service must be brought within one (1) year after it arises.

You agree to indemnify and hold harmless Silvane and its operators from and against any claims, losses, liabilities, and reasonable expenses (including legal fees) arising out of your use of the Service, Your Content, or your violation of these Terms or of any law or the rights of a third party.

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Any dispute arising out of or relating to these Terms or the Service will be subject to the exclusive jurisdiction of the state and federal courts located in Delaware, except where mandatory law in your country of residence gives you the right to bring proceedings where you live. You are also responsible for complying with any laws that apply to your own access to and use of the Service, including any applicable export or sanctions rules.

We may update these Terms from time to time. When we do, we will revise the effective date at the top of this page, and for material changes we will make reasonable efforts to notify you. Your continued use of the Service after the changes take effect means you accept the updated Terms. The current version always supersedes earlier ones.

Our Privacy Policy explains what information we collect and how we use and protect it. It forms part of these Terms, and by using the Service you also agree to it.

These Terms, together with our Privacy Policy, are the entire agreement between you and Silvane regarding the Service. If any provision is found unenforceable, the rest stays in effect and the unenforceable part is limited to the minimum extent necessary. Our failure to enforce any provision is not a waiver of it. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.

Feedback. If you send us ideas, suggestions, or other feedback about Silvane, you are welcome to — but you are never required to, and we are not obligated to keep it confidential. You allow us to use that feedback freely to improve the Service, with no obligation or payment to you.

If you have questions, concerns, or notices about these Terms, reach us at support@silvane.app.
