1. Information We Collect
Four Pillars ("the Service") collects the following information:
- Birth date, time, and gender — entered by you for chart calculation. Not stored on our servers; only the interpretation result is cached.
- IP-based location — approximate location (country, region, city) collected automatically. Precise GPS coordinates are never collected.
- Usage records — aggregate statistics such as reading count and access time for service analytics.
2. How We Use Your Information
- Generating and caching chart interpretations (faster responses for repeat requests)
- Understanding service usage and improving quality
- Regional usage statistics analysis
3. Third-Party Services
- Google Gemini API — generates chart interpretation text. Your birth chart data is sent to Google servers for processing.
- Vercel — hosting and database.
- Google AdSense — advertising. Google may use cookies to display personalized ads.
4. Share Feature
URLs generated via the Share button include your birth date, time, and gender. Sharing this URL makes that information visible to recipients. Sharing is entirely at your discretion.
5. Data Retention
- Chart interpretation cache: auto-deleted after 90 days
- Annual cycle cache: auto-deleted after 365 days
- Location statistics: retained indefinitely (aggregate only, not personally identifiable)
