Privacy Policy

Last updated: August 2026

YUVA ("we", "us", "our") respects your privacy. This policy explains what data we collect, why, and how we handle it.

Information We Collect

Account identity — email address and identity information provided through Clerk sign-in
Birth date and birth hour — to generate your chart reading
Usage data — AI chat messages, credit usage, session activity
Payment information — processed by Creem (we never store card numbers)

How We Use Your Data

To generate and display your Zi Wei Dou Shu birth chart
To authenticate your account through Clerk and map it to your YUVA profile
To track AI credit usage and subscription status
To process payments via Creem
To improve the app and fix bugs

Data Storage

Your YUVA business profile, saved birth data, account entitlements, and saved conversations are stored in a PostgreSQL database. Clerk owns customer login sessions; YUVA does not persist Clerk session tokens. Scoped payment and report-recovery tokens are stored as hashes where supported. We do not sell your data to third parties.

Third-Party Services

Clerk — account authentication and session management
Resend — product-transactional email delivery
Creem — payment processing
Anthropic — AI-powered chart readings (birth date context is sent to generate readings)
Vercel — frontend hosting

Data Retention

We retain your account data for as long as your account is active. Anonymous paid-report delivery emails may be retained for recovery and support, then redacted after the retention window. You may request deletion of your account and associated data by emailing hello@yuvachart.com.

Data Choices

Chart preview can be used before sign-in; saved Charts, Readings, and Ask history belong to your account. New relationship Match creation is not currently available. To delete your account, saved charts, messages, or historical relationship profiles, email hello@yuvachart.com from the email tied to your account.

Cookies & Sessions

Clerk manages the browser session used to keep you signed in. YUVA may use a separately scoped anonymous cookie for supported checkout recovery; it cannot authenticate a customer account. We do not use advertising cookies or third-party tracking.

Children's Privacy

YUVA is not directed at children under 13. We do not knowingly collect data from children under 13.

Changes

We may update this policy occasionally. Continued use of YUVA after changes means you accept the updated policy.
