Frequently Asked Questions
Do generated QR codes expire?
No. These are static QR codes that encode your data directly into the matrix pattern without third-party redirect links. They never expire.
How does a WiFi QR code work?
WiFi QR codes follow the standard `WIFI:S:ssid;T:type;P:password;;` format. When scanned by modern iOS or Android smartphones, the device prompts to join the network automatically.
Are my WiFi passwords uploaded to a server?
No. All QR matrix calculations happen purely inside your browser. No data leaves your machine.
