Engineering & Feature Specifications

Detailed technical capabilities covering our local vector generator, sub-50ms edge redirection infrastructure, and privacy-preserving scan telemetry.

01 / Vector Precision & Print Production

Deterministic mathematical vector output

QR matrices generated in QRnaly are calculated with pixel-perfect contrast checks and precision geometry. Exported vector files scale infinitely without blur or optical scanning degradation.

Level H Error Correction (30%): Allows center company logos and custom iconography without reducing optical readability.

Pure SVG Geometry: Clean vector paths compatible with Adobe Illustrator, Figma, and CorelDRAW.

300 DPI Print PDF: Direct A4/Letter print templates formatted for professional press.

02 / Dynamic Shortlink & Redirection Engine

Redirection Architecture FlowFast HTTP 302 Routing

1. Optical ScanDevice camera reads qrnaly.com/q/[slug]

2. Index LookupIndexed b-tree scan on PostgreSQL (sub-5ms)

3. Async TelemetryNon-blocking scan event recorded in background

4. HTTP 302 RedirectBrowser navigates directly to target URL

Instant updates post-printing

Dynamic QRs decouple the printed physical graphic from the digital destination. You can change where a code leads anytime in your dashboard without reprinting.

Zero Downtime Destination Switches: Updates apply globally within 1 second.

Grace Period & Asset Retention: Expired subscriptions maintain a 30-day grace period for printed collateral.

Dynamic Quotas: 1 code on Free trial, 50 on Pro, 500 on Business.

03 / Privacy-First Scan Telemetry

METRIC STORAGE

Authoritative Postgres

Scan telemetry is stored exclusively in partitioned PostgreSQL tables, not third-party SaaS trackers.

PRIVACY SHIELD

Salted SHA-256

Raw IP addresses are hashed using a rotating secret salt to compute unique visitor counts without storing PII.

SCANNER COOKIES

Zero Third-Party

No tracking cookies or advertising pixels placed on consumer phones when scanning your physical codes.

EXPORT FORMATS

Raw CSV Export

Export complete timestamped scan logs with OS, browser, and city for custom reporting and BI tools.

04 / Programmatic REST API v1.0

Automate QR code creation via REST API

Generate batches of dynamic QRs, retrieve scan telemetry, and update destinations programmatically.
