Privacy Policy

MTG Rack (“we”, “us”, “our”) respects your privacy. This policy explains what information we collect, how we use it, and your choices regarding your data.

1. Information We Collect

Account Information

When you create an account, we collect your email address and a display name or handle. Authentication is handled by Supabase Auth, and we do not store passwords directly.

Collection & Deck Data

We store the card collections, decklists, binders, and related metadata you create within the app. This data is essential for providing the service.

Usage Information

We may collect basic usage analytics such as page views, feature usage, and error logs to improve the service. We do not use third-party tracking pixels or sell your data to advertisers.

Device Information

Our mobile app may collect device identifiers for sync functionality and crash reporting. Camera access is used solely for card scanning and is processed on-device.

2. How We Use Your Information

• To provide and maintain the MTG Rack service
• To authenticate you and secure your account
• To display your public content (decks, profile) to other users
• To generate portfolio analytics and price tracking features
• To improve the service through aggregated, anonymized usage data
• To enforce our Terms of Service and moderate content
• To communicate important service updates

3. Data Sharing

We do not sell, rent, or trade your personal information. We may share data with:

• Service providers: Supabase (database/auth), Vercel (hosting) — these providers have their own privacy policies
• Legal requirements: If required by law, regulation, or legal process

Public decklists and user profiles are visible to anyone with the link. Private collections and binders are only accessible to you.

4. Data Storage & Security

Your data is stored in secure, managed databases with row-level security (RLS) ensuring users can only access their own private data. We use industry-standard encryption for data in transit (TLS) and follow security best practices.

5. Your Rights & Choices

• Access & Export: You can export your collection data at any time through the app
• Deletion: You can delete your account and associated data by contacting us or through account settings
• Visibility: You control whether your decks and profile are public or private
• Correction: You can update your profile information at any time

6. Cookies & Local Storage

We use essential cookies and browser local storage for authentication sessions and user preferences (such as view settings and theme). We do not use advertising or tracking cookies.

7. Children's Privacy

MTG Rack is not directed at children under 13. We do not knowingly collect personal information from children under 13. If we become aware of such collection, we will delete the information promptly.

8. Third-Party Services

MTG Rack integrates with third-party services for card data (Scryfall), commander analytics (EDHREC), and pricing information. These services have their own privacy policies, and we encourage you to review them. We cache data from these sources to reduce external requests and improve performance.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of significant changes through the application or via email. Continued use of MTG Rack after changes constitutes acceptance of the updated policy.

10. Contact

If you have questions or concerns about this Privacy Policy or your data, please contact us through the feedback mechanisms provided within the application.
