When you use our service, we process the geographic coordinates you query (latitude/longitude). These coordinates are not linked to your identity and are used solely to provide the flood risk analysis. We log coordinates in anonymized form (rounded to 3 decimal places) for aggregate usage statistics only. No account or registration is required to use the service.
Our servers automatically collect IP addresses, browser type, and access timestamps for security, rate limiting, and performance monitoring. These logs are retained for 30 days and then deleted. IP addresses are used for rate limiting (30 requests per hour) to prevent abuse of the service.
If you submit your email through our enterprise contact form or waitlist, we store your email address solely to respond to your inquiry or notify you about API access. You can request removal at any time by emailing us at office@terraflood.com.
