Summary
FieldToCAD is designed so parsing, localization, projection, visualization, and local export run entirely in your browser using the FileReader API, Web Workers, and local storage (OPFS / IndexedDB). Pro export is the explicit exception described below.
What we do not collect
- Survey point coordinates, observations, or raw field files
- Project geometry or traverse data
- Uploaded files of any kind during local processing
Optional cloud features
When Supabase is configured and you sign in, we store account metadata only: email, localization preset parameters (scale, rotation, shifts, and zone ID only, never coordinates), and Stripe billing subscription status. Row-level security restricts all data to the account owner.
Pro export
Pro export sends already-transformed grid points to a stateless Edge Function for LandXML generation. Points are processed in memory, never persisted or logged, and the function verifies subscription entitlement server-side.
Password safety
During account creation and password updates, FieldToCAD checks password safety using the Have I Been Pwned k-anonymity range API. Only the first five characters of a SHA-1 password hash are sent; the password itself is never sent.
Website analytics
When deployed on Vercel, we use Vercel Web Analytics to measure page views and referrers, and Vercel Speed Insights to measure Core Web Vitals (LCP, INP, CLS, and related load metrics) per page. This helps us understand which pages are useful and how fast they load. Analytics collects page URLs and referrer information only. Speed Insights collects performance metrics and page paths (query strings are stripped before send). Neither service collects survey coordinates, field files, or workspace job data.
