Privacy Policy

1. Information We Collect

• Automatically Collected (via Analytics): Usage data like IP address, browser type, device info, pages viewed, time spent, referral sources, and interactions (e.g., inputs for previews). Collected via Posthog (self-hosted/open-source analytics) for site improvement and performance monitoring. No personally identifiable information (PII) tied to individuals unless anonymized.
• Payment Data (via Stripe): For premium unlocks (single downloads, bundles, or subscriptions), Stripe processes payment details (card info, billing address if provided). We do not store or access full payment data—Stripe handles it securely under their privacy policy.
• Voluntary Email Submissions: If you submit your email for a discount or updates, we store your email address and send a welcome email plus occasional follow-ups (e.g., printing tips). You can unsubscribe at any time.
• Local Browser Storage: Draft inputs (localStorage) and premium unlock status (cookie for functionality, e.g., auto-save previews). Stored only on your device; not transmitted to us.
• Cookies: Essential cookies for site function (e.g., premium status, cookie consent banner). Analytics cookies via Posthog (anonymous). No marketing/third-party advertising cookies.

We only collect direct PII (like email addresses) when you voluntarily provide it for promotions or updates.

2. How We Use Information

• Provide and improve the service (generate accurate star maps using astronomy libraries).
• Process payments securely via Stripe.
• Analyze anonymous usage (Posthog) to fix bugs, optimize performance, and understand features.
• Comply with legal obligations.

No data sold or shared for marketing.

3. Third-Party Services

• Stripe: Processes payments. Subject to Stripe's Privacy Policy. We receive only transaction confirmation (no full card details).
• Posthog: Analytics tool configured for anonymized data; no PII collected. See Posthog privacy.
• Cloudflare: Hosting and edge infrastructure.
• Astronomy Libraries: Client-side processing (no data sent).

These providers act as processors; we ensure compliance via agreements.

4. Data Storage and Security

• Data processed at the edge (Cloudflare Workers) with TLS encryption.
• No central user database; minimal/no PII stored server-side.
• LocalStorage/cookies are device-specific.
• Retention: Analytics anonymized/retained as needed for improvement (up to 12 months); payment records per legal requirements.

We implement reasonable security (encryption, access controls) but no system is fully secure.

5. Your Rights (GDPR/CCPA/Others)

• Access, correct, delete data: Contact support@starmapco.com.
• Opt-out analytics: Clear browser cookies/storage or use Do Not Track (honored where possible).
• CCPA: No sale of personal information.
• GDPR lawful basis: legitimate interests (analytics/service), contract (payments). International transfers via adequacy/standard clauses.
• Children under 13: Service not directed; no knowing collection.

6. Cookies and Tracking

Essential for function; analytics optional (consent via banner). Manage via browser settings.
