When you use our service, we may collect:

• Birth details: Date of birth, time of birth, sex at birth, and optionally your birthplace. These are used solely to generate your Saju (BaZi) reading.

• Usage data: We may collect anonymized analytics data (pages visited, device type) through Google Analytics to improve our service.

2. How We Use Your Data

• Reading generation: Your birth details are sent to our AI service (OpenAI) to generate your personalized reading. We do not store raw birth details beyond the current session unless you create an account.
• Account & archive: If you provide your email, we store your reading in a secure database (Upstash Redis) so you can access it anytime from the "My Saju" portal.
• Authentication: We use one-time verification codes sent via email (Resend) to verify your identity. We do not use passwords.
