What Data We Collect

Contact Form: If you submit a message via the contact form, your name, email address, and message are collected solely to respond to your inquiry. No data is sold, shared, or reused for marketing purposes.

Analytics: Google Analytics 4 (via Google Tag Manager) is used to understand site performance and user interaction. It may collect anonymized technical data such as browser type, device, screen size, approximate location (city-level), and pages visited. IP addresses are not stored, and reports are aggregated. Analytics data helps improve site structure, content, accessibility, and performance.

Server and Security Logs: Our hosting provider automatically collects limited technical information—such as IP address, browser type, device identifiers, and access timestamps—for the purpose of maintaining security, detecting abuse, and ensuring system reliability. These logs are not used to personally identify visitors.

Site Chat Assistant:

  • Your question is transmitted securely via HTTPS to an AWS Lambda function.
  • The message is then processed by OpenAI's GPT API to generate a contextual response.
  • No personal data is stored or logged on our servers.
  • Your browser may temporarily store chat history in sessionStorage for your convenience.
  • Please avoid submitting sensitive or personal information in chat interactions.
