Yes, QR Code Studio Pro – Vector SVG, PNG & JPG Generator for OpenCart 4 & 3 is officially built with dual-engine architecture natively supporting OpenCart 4 (4.0.0.0 through 4.1.0.0+) and OpenCart 3 (3.0.0.0 through 3.0.3.9+). Separate, optimized packages are provided for each platform.

Absolutely. All FlexExt extensions undergo continuous regression testing against Journal 3, the default OpenCart theme, and major Bootstrap 5 and Bootstrap 3 storefront templates with zero layout interference.

The extension supports PHP 7.4, 8.0, 8.1, 8.2, and 8.3. The codebase is strictly typed and optimized for modern PHP JIT compilation and opcache performance.

Upon purchasing the extension on flexext.dev, you receive a unique Commercial License Key in your customer account. Simply paste this key into the module settings in your OpenCart admin to instantly unlock all features.

Not at all. Performance is our primary benchmark. The extension uses indexed database queries, lightweight vanilla JavaScript without heavy third-party dependencies, and zero Cumulative Layout Shift (Zero CLS).

Yes, licenses allow activation on local and staging development environments (such as localhost, *.test, *.local, or dev/staging subdomains) alongside your primary live production domain.

No. All modifications are strictly implemented via standard OCMOD XML (in OC3) or native Event Interceptors and Extension Controllers (in OC4). Your core OpenCart system files remain 100% untouched.

Yes, 100%. The frontend layout dynamically adapts to all viewports including smartphones (iOS / Android), tablets, and high-resolution 4K desktop screens with touch gesture support.

You can download updated .ocmod.zip packages directly from your flexext.dev customer portal. Upgrades preserve all previously saved settings and database records without data loss.

Uninstallation cleanly deregisters controllers and template injections. Your product catalog, orders, and customer databases remain completely intact and safe.

Yes, full multi-store support is built into the architecture. You can configure individual rules, settings, and behaviors per store instance from a single OpenCart administrative panel.

Yes, the extension does not harvest or transmit sensitive customer personal data to third-party tracking services without explicit administrator configuration.

Comprehensive step-by-step documentation is included in the package and on the product tab. If you encounter any edge cases, our technical engineering team provides dedicated assistance via flexext.dev.

No. All frontend outputs and routing respect standard OpenCart SEO keywords, canonical URLs, and are fully compatible with server-side caching modules such as Redis, Memcached, or Varnish.

We stand behind our software with a 100% functionality guarantee. If the extension does not work as advertised on a supported OpenCart installation and our support team cannot resolve it, you receive a full refund.
