## Frequently Asked Questions
### Do I need permission to use QR Studio codes commercially?
No permission required. All generated codes are 100% royalty-free for both personal and commercial use without attribution.

### Can you recover or edit a QR code I generated earlier?
Because QR Studio operates entirely client-side with zero server storage, we do not store your data. We cannot access, edit, or recover previously generated codes.

### What format should I use for commercial packaging print?
Always use the SVG vector export. It scales infinitely without raster degradation, ensuring optimal scannability at any print size.

### Why might a camera scanner fail to read a custom QR code?
Scanners fail most often due to low contrast between modules and the background, insufficient quiet zone margins (minimum 4 modules), or overly dense payloads without adequate Reed-Solomon error correction (ECC). When embedding logos, always select Level H.

### What are the performance limits for in-browser batch generation?
Because all rendering and ZIP packaging occurs directly in your browser's Web Worker thread without server uploads, batch generation can comfortably handle 500 to 2,000 codes depending on your device's available RAM.

### Why does QR Studio only generate static QR codes?
Static QR codes store all information directly inside the physical black-and-white matrix. Unlike dynamic codes, they require no intermediary redirect server, never expire, cannot be hijacked, and collect zero tracking telemetry.
