Fairwater Software, LLC ("we," "us," or "our") operates Deck Studio ("the Service"). This Privacy Policy explains how we collect, use, and protect your information when you use the Service.

1. Information We Collect

Account Information: When you create an account, we collect your email address and a password (stored in hashed form). If you register using a third-party provider (e.g., Google or Facebook), we collect the basic profile information provided by that service.

Collection Data: When you import your Magic: The Gathering Arena card collection, we store your card inventory data so that the Service can generate decks tailored to the cards you own.

Deck Building Data: We store the decks you create and the strategy descriptions you provide to the AI.

Usage Data: We collect information about how you interact with the Service, including pages visited, features used, and other analytical data.

2. How We Use Your Information

We use the information we collect to:

  • Provide, maintain, and improve the Service
  • Generate AI-powered deck recommendations based on your collection
  • Communicate with you about your account or the Service
  • Monitor usage patterns to improve user experience
  • Prevent fraud and ensure the security of the Service

3. Data Storage and Security

Your data is stored on secure servers and transmitted using encryption (TLS/SSL). We implement industry-standard security measures to protect your personal information. However, no method of electronic storage or transmission is completely secure, and we cannot guarantee absolute security.

4. Third-Party Services

The Service integrates with the following third-party services:

  • Authentication Providers: Google and Facebook for optional sign-in functionality. These services may collect information as described in their respective privacy policies.
  • AI Providers: We use third-party AI services to generate deck recommendations. Your strategy descriptions and collection data may be sent to these providers solely for the purpose of generating your requested deck.
  • Analytics: We use Google Analytics to collect anonymized usage data. This information helps us understand how users interact with the Service.

5. Cookies and Tracking

The Service uses cookies and similar technologies for authentication, security, and analytics purposes. You can control cookie settings through your browser preferences. Disabling certain cookies may affect the functionality of the Service.

6. Data Retention
