Privacy Policy
Last Updated: September 2026
1. Local Client-Side Calculation Guarantee
At DielineKit CAD, we understand that client packaging dimensions, new product unreleased prototypes, and custom brand artwork represent highly confidential trade secrets. All 2D geometric vector calculations, caliper clearances, and 3D WebGL renderings execute locally inside your web browser. Your dimension numbers and uploaded preview artwork files are never uploaded, stored, or indexed on our servers.
2. Information We Collect
When you authenticate via Magic Link or OAuth (Google, GitHub), we store your email address and account identifiers securely in Supabase with row-level security (RLS). For commercial purchases, payments are processed directly via PayPal’s PCI-DSS compliant servers. We do not process, transmit, or store credit card numbers on our servers.
3. Export Tokens & Security
When an export pass is redeemed, our backend generates a short-lived (15-minute) cryptographic HMAC-SHA256 signature to verify single-use authorization. Once verified, the CAD file stream is downloaded immediately and the token is marked used.
4. Third-Party Analytics & Cookies
We do not sell user data to advertising brokers. Minimal session cookies are utilized strictly to maintain your active authentication state and manage export credits.
