Privacy Policy
Last Updated: September 23, 2026
This Privacy Policy explains how Astrocartography Calculator ("we", "our", or "us") collects, uses, and protects information when you visit astrocartographycalculator.com.
1. Information We Collect
Account Information
If you create an account, we may collect information you voluntarily provide, such as your email address. An account is optional for generating a chart, but some features may require one.
Birth and Location Details
To generate an astrocartography chart, you may provide:
- Birth date
- Birth time (or an indication that the time is unknown)
- Birth location and related geographic coordinates
- Timezone
These details are used only to calculate planetary positions and draw chart lines. If you sign in and save a birth profile, you can edit or remove it later.
Usage Information
We automatically collect certain information when you visit the site, including:
- IP address
- Browser type and version
- Device and operating system
- Referring pages
- Pages viewed and time spent on the site
- Interaction and navigation data
We may use Microsoft Clarity for heatmaps, session recordings, and behavioral analytics to improve usability.
Advertising and Cookie Information
We may use third-party advertising services, including Google AdSense. These services may use cookies and similar technologies to collect browser and device identifiers, IP address, approximate location, and site interaction data in order to show ads, measure performance, and prevent fraud.
Place Search and Maps
When you search for a birth location, we send your query to geocoding and map providers so we can return matching places, timezones, and map tiles. Those providers process the query under their own policies.
2. How We Use Your Information
We use collected information to:
- Generate your astrocartography chart
- Prefill saved birth details if you have an account
- Operate, secure, and improve the website
- Respond to support requests
- Send account-related notices
- Display advertising where enabled
- Process payments if you purchase a paid plan
We do not use your birth chart as a public profile, and we do not sell your personal information.
3. How We Share Information
We may share information only:
- With service providers that help us run the site (hosting, authentication, analytics, maps, payments, advertising)
- To comply with law or lawful requests
- To protect the rights, safety, and security of users and the service
- In connection with a merger, acquisition, or similar transaction
Chart results are generated for you. We do not share your birth details with third parties for their own marketing.
4. Third-Party Services
We may use:
- Supabase for authentication and account data
- Microsoft Clarity for analytics and session insights
- Google AdSense for advertising
- Geocoding and map providers (such as GeoNames, OpenStreetMap-related services, CARTO, or Esri) for place search and basemap tiles
- Payment processors (such as Paddle or Stripe) if you subscribe
Each provider processes data under its own privacy policy.
5. Data Security and Retention
We use reasonable administrative and technical safeguards. No online transmission or storage is completely secure.
We keep personal information only as long as needed to provide the service, comply with law, resolve disputes, and enforce our agreements. Chart calculations you run without an account are not stored as a permanent personal profile.
6. Your Privacy Rights
Depending on your location, you may have the right to access, correct, delete, or object to certain processing of your personal information, and to withdraw consent where applicable.
To exercise these rights, contact support@astrocartographycalculator.com.
7. Children's Privacy
The service is not directed to children under 16. We do not knowingly collect personal information from children.
8. Changes
We may update this policy from time to time. The "Last Updated" date at the top will change when we do. Continued use of the site after an update means you accept the revised policy where permitted by law.
