- Does my data leave this browser?
- No. The QR code is generated locally in this tab - nothing is uploaded, tracked, or stored on a server.
- Is there a length limit?
- QR codes can hold up to roughly 4,000 characters of text, but codes with more data get denser and harder to scan - keep it under a few hundred characters for reliable scanning.
- Do these QR codes expire?
- No. Every code here encodes your data directly (a "static" QR code), so it scans forever - there is no subscription or dynamic redirect that can be switched off later.
