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.
• 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.
• Email preferences: your choices about which types of emails you wish to receive from us.
• Social media messages: if you contact us via Instagram Direct Messages, we collect the content of your messages, your Instagram username, and any birth data you voluntarily share in conversation. We use this to provide personalized astrology guidance.

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, purchase confirmations, password resets).
• To send promotional emails about your chart and readings, if you have opted in.
• To send personalized weekly chart emails to Pro subscribers who have opted in.
• To respond to your questions and provide astrology guidance via Instagram Direct Messages.
• To improve our services and fix bugs.

We do not sell your personal data for money. We do share certain online identifiers and cookie data (such as advertising and analytics identifiers) with partners like Google so we can measure and advertise our service, including remarketing, where you have consented. You can withdraw consent or opt out of analytics and advertising cookies at any time through your cookie settings.

You can manage your email preferences at any time from the Email Preferences page, or by clicking the unsubscribe link in any marketing email. Transactional emails (chart delivery, purchase confirmations, password resets) cannot be disabled as they are necessary for service operation.

3. AI-Generated Readings

Our birth chart readings are generated using third-party AI language models (currently NVIDIA NIM and Anthropic). For your one-time reading, only derived chart data — planetary positions and aspects — is sent to the AI provider; your name, email address, and birth location are not. If you use the interactive chart chat, the chart name and your birth details (date, time, and location) may be sent to the AI provider so it can answer your questions. We do not use your data to train AI models, and your readings are not shared with other users.

4. Social Media Messaging

When you message our Instagram account (@synthesisastrology), we receive and process your messages through the Meta (Instagram) Messaging API. Here is how we handle this data:

• What we collect: your Instagram username, message content, and any birth data you choose to share (date, time, location of birth).
• How we use it: to provide personalized astrology responses, including transit interpretations and chart insights based on data you share.
• AI-assisted responses: our responses are generated with the help of AI language models. Your message content and any birth data you share may be sent to the AI provider to generate a relevant response. We do not send your Instagram username or profile information to the AI provider.
• Data retention: conversation history is stored to maintain context across messages. You can request deletion of your conversation data at any time by contacting us.
• No marketing use: we do not use your DM conversations for advertising, marketing, or any purpose other than providing the astrology guidance you requested.

5. Data Storage & Security

Your data is stored on secure servers with encrypted connections (HTTPS/TLS). Passwords are hashed and never stored in plain text, and payment processing is handled entirely by Stripe, a PCI-compliant payment processor. Your data may be processed in the United States and in other countries where we or our service providers operate. Where personal data is transferred outside the EEA or the UK, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses, the UK International Data Transfer Addendum, or the EU-US Data Privacy Framework, where applicable.

6. Cookies, Analytics & Advertising

We use browser local storage to keep you signed in and to remember your preferences. For analytics and advertising we use Umami, a self-hosted, cookieless analytics tool that does not set cookies or track you across websites — and, subject to your consent where required, Google Tag Manager, which loads Google Analytics 4 (analytics cookies), Google Ads (advertising and remarketing cookies), and Microsoft Clarity (session-replay and usage analytics). These tools set cookies and similar identifiers. If you are in the EEA or the UK, we ask for your consent through a cookie banner before any non-essential cookies are set, and you can change or withdraw your choices at any time.

7. Your Rights

You can:

• Access, and receive a copy of, the personal data we hold about you — including your saved charts — in a portable, machine-readable format.
• Ask us to correct inaccurate personal data, or to delete your account and all associated data (right to erasure).
• Opt out of promotional and marketing emails via the Email Preferences page or by clicking unsubscribe in any email.
• Restrict or object to certain processing, withdraw consent at any time, and lodge a complaint with your local data protection supervisory authority. We aim to respond to any privacy request within one month.

8. 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, and when you opt in to receive marketing emails or consent to non-essential analytics and advertising cookies. You may withdraw consent at any time by updating your preferences, changing your cookie settings, or deleting your account.
• Contract performance: to deliver paid readings and subscriptions you have purchased.
• Legitimate interest: for service improvement, security monitoring, and fraud prevention.

9. 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, and generated readings — is permanently removed within 30 days. Payment records may be retained longer as required by tax and accounting regulations.

10. Third-Party Services

We use the following third-party services:

• Stripe for payment processing.
• Brevo (primary) and SendGrid (fallback) for transactional and marketing emails.
• Third-party AI / LLM providers (currently NVIDIA NIM and Anthropic) for AI-generated readings and chart chat. For the one-time reading, only chart data (planetary positions, aspects) is sent — not your name, email, or birth location. The interactive chart chat may also send the chart name and birth details (date, time, and location) so it can answer your questions.
• OpenCage / OpenStreetMap for converting your birth location into geographic coordinates needed for chart calculation.
• Meta (Instagram) for receiving and responding to Instagram Direct Messages through the Instagram Messaging API. Messages are transmitted through Meta's servers.
• Analytics, advertising & operational providers: Google (Google Tag Manager, which loads Google Analytics 4 and Google Ads) for analytics, advertising, and remarketing; Microsoft Clarity for session-replay and usage analytics, which may receive identifiers and is governed by Microsoft's privacy terms; Sentry for error monitoring, which may process technical data, including your email address, when an error occurs; RevenueCat for managing subscriptions purchased through the Apple App Store; and Umami, our self-hosted, cookieless analytics. Non-essential analytics and advertising tools load only with your consent where required.

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

11. Children's Privacy

Synthesis Astrology is not intended for children under 16. We do not knowingly collect personal data from anyone under 16 (or the applicable minimum age of digital consent in your country) without verifiable parental or guardian consent. If you believe a child has provided us with personal data, please contact us and we will delete it.

12. California Privacy Rights (CCPA)

If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA):

• Right to know: you may request a copy of the personal information we have collected about you in the past 12 months.
• Right to delete: you may request deletion of your personal information, subject to certain legal exceptions.
• Right to opt out of sale or sharing: we do not sell your personal information for money. However, our use of advertising and analytics cookies (such as Google Ads) may be considered a "sale" or "share" of personal information under the CCPA. You may opt out at any time through your cookie settings or by contacting us.
• Non-discrimination: we will not discriminate against you for exercising your CCPA rights.

To exercise any of these rights, email us at synthesisastrology@outlook.com. We will respond within 45 days.
