Privacy Policy
Last Updated: January 1, 2025
Introduction
Welcome to MyBirthChart (“we,” “our,” or “us”). We are committed to protecting your privacy and ensuring transparency about how we handle your information. This Privacy Policy explains what data we collect, how we use it, and what rights you have regarding your personal information when using our birth chart calculator at mybirthchartcalculator.com (the “Service”).
Data Collection
Our birth chart calculator is designed with privacy as a core principle. All astrological calculations are performed entirely on the client side — meaning in your web browser. We do not transmit, store, or retain any birth data (including your name, birth date, birth time, or birth location) on our servers.
When you enter your birth details into our calculator, that information stays on your device and is used solely to perform the astronomical calculations needed to generate your natal chart. Once you close or refresh the page, all entered data is cleared from memory.
Cookies and Analytics
We use Google Analytics 4 (GA4) to understand how visitors interact with our website. GA4 uses cookies to collect anonymized, aggregated information such as the number of visitors, the pages they visit, and the time spent on each page. This data helps us improve the user experience and does not personally identify you.
You can control cookie preferences through your browser settings. Most browsers allow you to refuse cookies or delete existing cookies. Please note that disabling cookies may affect certain website functionality.
Third-Party Services
Our Service uses the following third-party services:
- Photon/Komoot Geocoding API: When you search for a birth city, your search query is sent to the Komoot Photon API to retrieve geographic coordinates. This is a free, open-source service that does not require authentication. We do not control the data practices of this third-party service.
- Google Analytics 4: Used for website analytics as described above. Google's privacy policy applies to the data collected through this service.
Data Storage
We do not operate any databases or server-side storage for user data. Your birth chart information exists only in your browser's memory during your active session. When you download your chart as a PNG image, that file is created locally on your device — we do not receive or store a copy.
Your Rights
Since we do not store personal data, there is no personal information to access, modify, or delete from our systems. If you have concerns about the data collected by Google Analytics, you can opt out using the Google Analytics Opt-out Browser Add-on or by adjusting your browser's cookie settings.
Children's Privacy
Our Service is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.
Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last Updated” date. We encourage you to review this page periodically for the latest information about our privacy practices.
