- 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.
- Which number format should I use?
- Use the full international format with a country code (e.g. +1 555 123 4567) so it dials correctly no matter where the phone scanning it is set up.
- 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.
