Your Data, Protected

Welcome to AstroChartus. Your birth chart is one of the most personal documents you'll ever encounter — a map of the sky at the exact moment you drew your first breath. We treat it with the reverence it deserves.

This Privacy Policy explains how AstroChartus (“we,” “us,” or “our”) collects, uses, protects, and shares your personal information when you use our website and services at astrochartus.com. By using our services, you consent to the practices described in this policy.

We are committed to transparency. If anything in this policy is unclear, please contact us and we will be happy to explain.

We collect only the information necessary to provide you with accurate, personalized astrological services. This includes:

Account Information

• Your name, email address, and password (password is hashed and never stored in plain text)
• Profile preferences such as display settings and notification choices

Birth Data

• Date of birth, time of birth, and place of birth — the three coordinates required to calculate your natal chart with astronomical precision
• This data is used exclusively for chart computation using VSOP87 planetary theory and is never shared with third parties for marketing purposes

Usage Data

• Pages visited, features used, session duration, and interaction patterns — collected to improve our services
• Device type, browser, operating system, and IP address — collected automatically for security and analytics

Payment Information

• Subscription and billing data is processed securely through Stripe. We do not store your full credit card number, CVV, or banking details on our servers

Communications

• Messages you send us through our contact form, support channels, or email correspondence

Every piece of data we collect serves a specific purpose. We use your information to:

• Generate your birth chart — computing planetary positions, house cusps, and aspects from your exact birth coordinates using Swiss Ephemeris calculations
• Deliver personalized horoscopes — daily, weekly, and monthly forecasts based on real-time transits to your natal chart, not generic sun-sign predictions
• Create in-depth reports — personality profiles, relationship compatibility analyses, and life purpose readings derived from your unique chart data
• Manage your account — authentication, subscription billing, preference storage, and customer support
• Improve our services — understanding how users interact with our platform so we can refine the experience, develop new features, and fix issues
• Communicate with you — sending service-related emails (billing confirmations, security alerts, feature announcements) and responding to your inquiries
• Ensure security — detecting and preventing fraud, abuse, and unauthorized access to your account

We do not use your birth data for any purpose other than astrological computation. We will never use your personal information to build advertising profiles or sell targeted ads.

We take the security of your personal and astrological data seriously. Our protective measures include:

• Encryption in transit — all data transmitted between your browser and our servers is encrypted using TLS 1.2+ (HTTPS)
• Encryption at rest — your birth data and personal information are encrypted in our databases
• Password hashing — passwords are hashed using industry-standard algorithms and are never stored in readable form
• Secure payment processing — financial transactions are handled by Stripe, a PCI DSS Level 1 certified payment processor
• Content Security Policy — strict CSP headers protect against cross-site scripting and injection attacks
• Access controls — only authorized team members have access to user data, and access is logged and audited
• Regular security reviews — we continuously monitor and update our security practices to address emerging threats

While no system is perfectly secure, we are committed to employing best practices and staying vigilant. If you discover a security vulnerability, please report it to us responsibly.

We do not sell your personal data. We never have and we never will. Your birth chart, personal information, and usage data are not commodities.

We may share limited information with the following categories of service providers, solely to operate our platform:

• Hosting & infrastructure — Vercel (website hosting and serverless functions)
• Payment processing — Stripe (subscription billing and payment handling)
• Email delivery — Resend (transactional emails such as receipts, password resets, and support replies)
• Analytics — Google Analytics (anonymized usage statistics to improve our services)

Each of these providers is contractually obligated to protect your data and may only use it to perform services on our behalf.

We may also disclose information when required by law, in response to a valid legal process, or to protect the rights, property, or safety of AstroChartus, our users, or the public.

You have meaningful control over your personal data. Depending on your jurisdiction, your rights may include:

• Right to access — request a copy of all personal data we hold about you
• Right to correction — update or correct inaccurate or incomplete information
• Right to deletion — request that we delete your account and all associated data permanently
• Right to restriction — ask us to limit how we process your data in certain circumstances
• Right to data portability — receive your data in a structured, machine-readable format
• Right to object — object to processing of your data for specific purposes
• Right to withdraw consent — revoke previously given consent at any time, without affecting the lawfulness of prior processing

To exercise any of these rights, please contact us. We will respond to your request within 30 days.

We use cookies and similar technologies to provide a functional, secure, and personalized experience. Here's what we use:

Essential Cookies

Required for the platform to function — session management, authentication, and security tokens. These cannot be disabled.

AstroChartus is not intended for children under the age of 13 (or the applicable minimum age in your jurisdiction). We do not knowingly collect personal information from children.

If you are a parent or guardian and believe your child has provided us with personal data, please contact us immediately. We will promptly delete the information and close the associated account.

AstroChartus operates globally, and your data may be processed in countries other than your own. Our infrastructure is hosted on Vercel's global edge network, with primary data processing in the United States.

• Deleted accounts — when you delete your account, we permanently remove your personal data within 30 days, except where retention is required by law
• Contact messages — support correspondence is retained for up to 12 months to provide continuity in customer service
• Analytics data — anonymized usage statistics may be retained indefinitely as they cannot be linked back to you

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make material changes:

• We will update the “Last updated” date at the top of this page
• For significant changes, we will notify registered users by email
• We will post the revised policy on this page at least 14 days before changes take effect

Your continued use of AstroChartus after the effective date constitutes acceptance of the updated policy.
