1. Zero-Server Computing Architecture

SquarebodyTech is built using modern pre-compiled static architecture deployed globally across edge networks. There are zero traditional relational databases, zero user registration requirements, and zero backend sessions that can be compromised or leaked.

When you use our VIN decoder, RPM simulator, or cylinder head torque sequence tools, the calculation logic runs entirely within the JavaScript sandbox of your local browser. No vehicle identification numbers, engine specifications, or user queries are sent across the wire.

2. Zero Third-Party Tracking & Cookie Free

SquarebodyTech uses no third-party tracking pixels, no advertising trackers, and no persistent cross-site tracking cookies. We do not participate in behavioral advertising ad exchanges or data broker syndicates.

Any configuration preferences—such as your selected model year in the trim matrix or high-contrast dark theme mode—are saved in standard browser localStorage on your machine alone.

3. Cryptographic Edge Delivery & Subresource Integrity

All web assets are served over encrypted TLS 1.3 connections with automated HSTS (HTTP Strict Transport Security) headers. Modern edge security rules prevent clickjacking, cross-site scripting (XSS), and unauthorized iframe embedding.

4. Vulnerability Disclosure & Technical Integrity

If you discover an engineering calculation anomaly or web security vulnerability, please submit details via our interactive Technical Correction Drawer or by contacting our engineering desk at [email protected].
