Privacy Policy

Information you provide. When you create an account, we collect your email address and, if you sign in with Google or Apple, the basic profile information they share with us (such as your name and email). Your profile may also include a username, display name, avatar, short bio, and color identity. As you use Silvane, you add the content that makes up your collection — binders, decks, lists, wants, cards marked for trade, quantities, prices you paid, notes, tags, watchlists, and price alerts. We also receive anything you send us directly, such as support messages and the content you submit to AI features — for example a rules question, or a photo you ask the Rules Judge about.

Information we collect automatically. When you use the Service, we automatically receive basic technical and usage information needed to run and secure it — for example your IP address, device and browser type, operating system, app version, timestamps, general activity within the app, and diagnostic or crash data. We may infer approximate location (such as country) from your IP address. We do not collect precise GPS location.

We use the information we collect to:

• Provide the Service — store your collection and keep it in sync across your devices;
• Create and secure your account, and sign you in;
• Send notifications you have turned on, such as watchlist or price alerts;
• Respond to your questions and provide support;
• Understand how the Service is used so we can fix problems and improve it;
• Detect, prevent, and address fraud, abuse, security issues, and violations of our Terms;
• Comply with the law and enforce our agreements.

We do not use your information to show you third-party advertising, and we do not sell it.

Silvane’s AI features — such as the Rules Judge and AI-powered search — send what you submit (your question or search, any photo you attach, and the context needed to answer) to a third-party AI provider solely to generate a response for you. Please do not include sensitive personal information in those messages. We do not sell this content, and we do not use your private collection to build advertising or marketing profiles.

You can connect AI assistants you already use — such as Claude or ChatGPT — to your Silvane account through our MCP integration. When you authorize a client, the data it reads from (or writes to) your account flows to that provider and is handled under that provider’s own privacy policy, not this one. You choose which client to connect, you control what you ask it to do, and you can revoke its access at any time from that client’s settings.

Paid subscriptions are billed by Apple or Google through your app-store account. We never receive or store your card number or full payment details. We use RevenueCat, a subscription-management service, to know which plan you are on: it processes your account identifier, store transaction identifiers, the product you bought, and the subscription’s status, and notifies us of lifecycle events such as purchases, renewals, cancellations, and expirations.

We store your current plan, your subscription history, and — for features with usage limits, such as scans and AI searches — usage counters, so we can apply each plan’s limits correctly.

We share information only in the limited ways described here.

• Service providers. We rely on trusted companies to run Silvane — including cloud hosting and database, data synchronization, sign-in providers (Google and Apple), our AI provider, subscription management (RevenueCat), and push-notification delivery. They may process your information only to provide these services to us and are required to protect it.
• When you choose to share. If you make a binder, deck, list, view, or profile public, it becomes visible to anyone with the link, and your username, display name, and avatar appear on those public pages. You control this and can make items private again at any time.
• Legal and safety. We may disclose information if required by law or legal process, or where we believe it is necessary to protect the rights, property, or safety of Silvane, our users, or the public.
• Business transfers. If Silvane is involved in a merger, acquisition, or sale of assets, information may be transferred as part of that transaction; we will let you know and honor this Policy.

We do not sell your personal information.

On the web, we use essential cookies to keep you signed in and to remember basic preferences (such as your light or dark theme). In the app, Silvane stores your collection on your device so it works offline and stays in sync. We do not use advertising cookies or cross-site tracking.

Because we do not track you across other websites, our Service does not respond to browser “Do Not Track” signals.

We keep your information for as long as your account is active. When you delete your account, we remove your personal data from our active systems within 30 days, except where we need to keep some of it for legal, security, or fraud-prevention reasons. Residual copies in routine backups are overwritten in the ordinary course, and anything you shared publicly may persist for a time in cached or anonymized form that no longer identifies you. Records of purchases and subscription events may be kept longer where tax, accounting, or other legal obligations require it.

You are in control of your information. From within Silvane you can review and update your profile, change what is public or private, manage the notifications you receive, export your data, and delete your account. Deleting your account removes your personal data as described above.

Depending on where you live — for example in the European Economic Area, the United Kingdom, or California — you may have additional rights, such as the right to access, correct, delete, or port your personal information, or to object to or restrict certain processing. To make a request, email us at support@silvane.app and we will respond as required by applicable law. We will not discriminate against you for exercising your rights.

We use reasonable technical and organizational measures to protect your information, such as encryption in transit and access controls. However, no method of transmission or storage is completely secure, so we cannot guarantee absolute security. Please help keep your account safe by protecting your login credentials.

Silvane is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child under 13 has provided us with information, please contact us at support@silvane.app and we will delete it.

Silvane is operated from, and relies on service providers in, the United States and other countries. Your information may be processed in countries whose data-protection laws differ from those where you live. Where required, we take steps to ensure your information receives an appropriate level of protection when it is transferred.

We may update this Privacy Policy 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 Policy.

If you have any questions or requests about this Privacy Policy or your information, reach us at support@silvane.app.
