Privacy & Security
SpanInsight is built with a strict Privacy-First architecture:
Direct Cloud VM Routing: When connected to Google Colab, code execution and data processing run directly in your private Colab sandbox. No third-party servers intermediate your raw dataset files.
Encrypted Gateway Transit: All AI prompts sent to the gateway are encrypted via TLS 1.3 with cryptographic client challenge headers.
Turnstile Bot Shield: Public survey forms on forms.spaninsight.com require non-intrusive Cloudflare Turnstile human verification.
Data Sovereignty: Exported notebooks (.ipynb), CSV responses, and PDF reports reside 100% on your local device.
