Privacy Policy

Last updated: May 6, 2026

Our Privacy Commitment

Your data stays on your device. Contour Digitizer processes all uploaded images entirely within your browser. We have no access to your contour plots, simulation results, or any FEA data you analyze with our tool. This is enforced by our architecture, not just our policy.

Introduction

Contour Digitizer ("we", "us", or "our") operates the website contourdigitizer.com and the Contour Digitizer application (app.contourdigitizer.com). This Privacy Policy explains how we collect, use, and protect your personal information when you use our services.

Contour Digitizer is suitable for use by professionals in regulated industries (defense, aerospace, nuclear, etc.) due to our local-processing architecture:

  • No data leaves your device when using the application for image analysis.

  • Air-gapped compatible (desktop version, when available).

However, users are responsible for compliance with their organization's specific data handling requirements (ITAR, EAR, NIST 800-171, CMMC, etc.). We recommend consulting your security officer before using any tool with controlled information.
