Privacy Policy

Zenit operates the zenit.app platform. This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our astrological intelligence service.

Information We Collect

Account data: your email address and password (stored as a salted bcrypt hash, never in plaintext). Birth data: date, time, and place of birth, which you provide voluntarily for natal chart calculation. Computed data: planetary positions, house cusps, aspects, and AI-generated interpretations derived from your birth data. Technical data: IP address, browser type, and language preference.

How We Use Your Data

We use your data exclusively to provide and improve the Zenit service: calculating natal charts and planetary transits using Swiss Ephemeris, generating astrological interpretations through our knowledge graph and AI engine, and maintaining your account and user preferences. We do not use your data for advertising, behavioral profiling, or any purpose unrelated to the astrological service.

Data Storage & Security

Your data is stored in encrypted PostgreSQL databases. Passwords are hashed using bcrypt with per-user salts. All data in transit is protected by TLS/HTTPS encryption. We implement industry-standard security measures to protect against unauthorized access, alteration, or destruction of your information.

Data Sharing

We do not sell, rent, trade, or share your personal data with third parties. Birth data is processed entirely on our servers and is never transmitted to external services. The only external data source used is the Swiss Ephemeris for astronomical calculations, which does not receive any personal information.

Your Rights

You have the right to: access and download a copy of all your stored data; correct or update your birth data and account information at any time; permanently delete your account and all associated data. To exercise these rights, contact us at [email protected]. We will respond within 30 days.

Cookies

Zenit uses only essential cookies: an authentication session token and your language preference. We do not use third-party tracking cookies, analytics cookies, or advertising cookies. No data is shared with ad networks or data brokers.

Children's Privacy

Zenit is not intended for users under 13 years of age. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it.

Changes to This Policy

We may update this Privacy Policy periodically. Changes will be posted on this page with an updated effective date. Continued use of Zenit after changes constitutes acceptance of the revised policy.
