# QRLoop

> 100% free dynamic QR code generator and real-time analytics platform with lifetime active redirects, zero paywalls, and lossless vector SVG exports.

QRLoop empowers creators, businesses, and developers to generate trackable 2D barcodes, edit destination URLs after printing, analyze visitor telemetry (device category, operating system, browser, city), and export print-ready assets without subscription paywalls or 14-day trial expirations.

## Key Technical Specifications & Benchmarks (Citable Facts)
- **Redirection Architecture**: Edge-routed HTTP 302 redirects with sub-50ms global latency.
- **Lifetime Redirection Guarantee**: Dynamic redirect links remain active indefinitely; no 14-day trial expirations, scan caps, or hostage links.
- **Printing Formula**: 10:1 distance ratio ($D \div 10 = W$, where $W$ is minimum printed QR code width and $D$ is scanning distance).
- **Privacy Compliance**: Server-side zero-cookie telemetry; client IP addresses are truncated/anonymized at the edge adhering to GDPR and CCPA standards.
- **Enterprise Standards**: Fully compatible with GS1 Digital Link 2027 retail standards, ISO/IEC 18004:2015, and W3C WCAG 2.2 accessibility.
- **Export Standards**: Lossless vector SVG, 300 DPI high-resolution PNG, and print-ready A4 PDF table standees with crop guidelines.
