This Privacy Policy describes how DIY Fertility ("we", "us", or "our") collects, uses, and protects information when you use the REI Oral Board Prep service ("Service"), accessible through our ChatGPT-based application and the API at api.diyfertility.com.

1. Information We Collect

Account Information: When you create an account, we collect your email address, display name, and a hashed version of your password. If you sign in with Google, we receive your name and email from Google.

Usage Data: We record your quiz activity, including questions attempted, answers provided, scores, and timestamps. This data powers your personalized progress tracking and smart question selection.

Payment Information: Subscription payments are processed by Stripe. We store your Stripe customer ID and subscription status but never see or store your credit card number, which is handled entirely by Stripe.

Feedback: If you submit feedback through the Service, we store your message and any associated case reference.

2. How We Use Your Information

• To provide and personalize the Service (progress tracking, smart case selection, accuracy stats)
• To process your subscription and manage billing
• To improve the question bank and study materials based on aggregate usage patterns
• To respond to feedback and support requests
• To detect and prevent abuse, fraud, or security incidents
