Privacy Policy

1. Information We Collect

When you use Synthesis Astrology, we may collect:

• Account information: email address and password when you create an account.
• Birth chart data: name, date of birth, time of birth, and birth location that you enter to generate charts.
• Chat conversations: if you use the chart chat feature, your messages and AI responses are stored to provide contextual follow-up readings.
• Referral source: how you found Synthesis (e.g. search engine, referral link) to help us understand where our users come from.
• Payment information: processed securely through Stripe. We never store your credit card details on our servers.

2. How We Use Your Information

• To calculate and display your birth chart readings.
• To save your charts to your account for future access.
• To process payments for readings and subscriptions.
• To send transactional emails (chart delivery, account updates).
• To improve our services and fix bugs.

We do not sell, rent, or share your personal data with third parties for marketing purposes.

3. AI-Generated Readings

Our birth chart readings are generated using AI language models. Your birth data is sent to the AI provider solely to produce your reading. We do not use your data to train AI models, and readings are not shared with other users.

4. Data Storage & Security

Your data is stored on secure servers with encrypted connections (HTTPS/TLS). Passwords are hashed and never stored in plain text. Payment processing is handled entirely by Stripe, a PCI-compliant payment processor.

5. Cookies & Analytics

We use browser local storage to maintain your login session and preferences. We use Umami, a privacy-focused, self-hosted analytics tool that does not use cookies, does not collect personal data, and does not track users across websites. No third-party tracking cookies are used on this site.

6. Your Rights

You can:

• Access and download your saved chart data at any time.
• Delete your account and all associated data by contacting us.
• Opt out of non-essential emails.

7. Legal Basis for Processing (GDPR)

We process your personal data on the following bases:

• Consent: when you create an account and provide birth data for chart calculation. You may withdraw consent at any time by deleting your account.
• Contract performance: to deliver paid readings and subscriptions you have purchased.
• Legitimate interest: for service improvement, security monitoring, and fraud prevention.

8. Data Retention

We retain your account data and saved charts for as long as your account is active. If you delete your account, all personal data — including birth details, saved charts, chat history, and generated readings — is permanently removed within 30 days. Payment records may be retained longer as required by tax and accounting regulations.

9. Third-Party Services

We use the following third-party services:

• Stripe for payment processing.
• Brevo (primary) and SendGrid (fallback) for transactional emails.
• Google Gemini for AI-generated readings. Only chart data (planetary positions, aspects) is sent — not your name, email, or birth location.
• OpenCage / OpenStreetMap for converting your birth location into geographic coordinates needed for chart calculation.
• Logtail and Sentry for application monitoring and error tracking.

Each service has its own privacy policy governing how they handle data.

10. Children's Privacy

Synthesis Astrology is not intended for children under 13. We do not knowingly collect data from children under 13.

11. Changes to This Policy

We may update this policy from time to time. Changes will be posted on this page with an updated date.
