1. Introduction

This Privacy Policy explains how Mulligan, operated by eldrazi.dev ("we", "us", or "our"), collects, uses, and protects your information when you use our Service.

2. Information We Collect

Account Information

When you create an account, we collect your email address, display name, and any profile information you choose to provide. If you sign in through a third-party provider, we receive basic profile information from that provider.

Usage Data

We automatically collect information about how you interact with the Service, including pages visited, features used, and playtest activity. We use Vercel Analytics to collect anonymized performance and usage metrics.

User-Generated Content

We store content you create on the Service, including saved hands, comments, votes, replays, puzzles, and decklist references.

Patreon Data

If you connect your Patreon account, we receive your Patreon member ID, email, subscription tier, and payment status to manage premium features. We do not store your payment details—those are handled entirely by Patreon.

3. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the Service
• Authenticate your identity and manage your account
• Enable community features such as comments, voting, and shared replays
• Manage premium subscriptions and feature access
• Analyze usage patterns to improve the user experience
• Communicate important updates about the Service

4. Information Sharing

We do not sell your personal information. We may share information in the following limited circumstances:

• Public content: Hands, comments, replays, and puzzles you create may be visible to other users depending on visibility settings
• Service providers: We use third-party services (Vercel for hosting and analytics, PostgreSQL for data storage, Patreon for subscriptions) that may process data on our behalf
• Legal requirements: We may disclose information if required by law or to protect our rights and the safety of users

5. Data Storage & Security

Your data is stored in a PostgreSQL database hosted with industry-standard security practices. We use HTTPS for all data transmission. While we take reasonable measures to protect your information, no method of electronic storage is 100% secure.

6. Cookies & Tracking

We use essential cookies for authentication and session management. Vercel Analytics collects anonymized, privacy-friendly usage data without using cookies for tracking. We do not use third-party advertising cookies.

7. Third-Party Services

The Service integrates with the following third-party services:

• Scryfall: Card data and images (subject to Scryfall's terms of use)
• Moxfield: Decklist imports (subject to Moxfield's terms)
• Patreon: Subscription management (subject to Patreon's privacy policy)
• Vercel: Hosting and analytics (subject to Vercel's privacy policy)

Each of these services has its own privacy policy governing how they handle your data.

8. Your Rights

You have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information

• Export your data in a portable format

9. Children's Privacy

10. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Your continued use of the Service after changes constitutes acceptance of the revised policy.
