Do QR codes created with VividQR expire or have scan limits?

No, never. VividQR generates direct, static QR codes without any intermediary redirect servers. Once generated, your QR code will work permanently with unlimited scans.

Is my personal data or Wi-Fi password stored on any server?

No. VividQR operates 100% entirely inside your browser (Client-Side). Your Wi-Fi passwords, contact details, emails, and crypto addresses are never transmitted over the network or saved in any remote database.

Which download format should I choose: SVG or PNG?

For print materials (posters, billboards, flyers, packaging, business cards), we recommend downloading SVG because it can be scaled infinitely without quality loss. For digital use, high-resolution PNG is ideal.

How do I ensure my QR code with a custom logo scans reliably?

When adding a center logo, error correction is set to High (H - 30% recovery) with a clear margin around the logo. Ensure strong color contrast between QR code modules and the background.

Can I use VividQR codes for commercial projects and business marketing?

Yes. All generated QR codes are free for both personal and commercial use without watermarks, attribution requirements, or hidden paywalls.
