Frequently Asked Questions
Will my QR code have a watermark?
No — CalcNation's QR code generator adds absolutely no watermark, logo, or branding to your generated QR codes. The downloaded PNG or SVG is completely clean and ready for commercial use. This is unlike many competitors who add "generated by" text on free plans.
Do I need to create an account?
No account or sign-up required. Open the tool, enter your content, and download your QR code immediately. No email address, no password, no cookies for tracking. The tool works entirely client-side — nothing is stored on CalcNation's servers.
How many QR codes can I generate for free?
Unlimited — there are no daily or monthly generation limits. Generate as many QR codes as you need. The batch generator lets you create up to 500 QR codes in a single session. All features — logo embed, custom colors, SVG export, bulk generation, and QR decoding — are permanently free.
Can I use these QR codes commercially?
Yes — QR codes generated on CalcNation can be used for any commercial purpose including product packaging, restaurant menus, business cards, signage, advertisements, and marketing materials. There is no licensing restriction on your use of the generated QR codes.
Is my data private when generating QR codes?
Completely private. All QR generation happens in your browser using JavaScript — no content is sent to CalcNation's servers. Your WiFi passwords, UPI IDs, contact details, and URLs never leave your device. The QR decoding feature also runs locally using the BarcodeDetector API without any server upload.
Can I generate QR codes for my business on mobile?
Yes — CalcNation works on all devices including smartphones and tablets. The QR generator is responsive and works on Chrome and Safari on iOS/Android. However, for batch generation and SVG export, a desktop browser is recommended for the best experience.
