常见问题 (FAQ)

Does this QR code expire?
Never! This is a **static** QR code, meaning your text or URL data is directly encoded into the image itself. It will work forever without relying on any servers.
Is my data sent to the cloud?
Absolutely not. The entire QR code generation process happens locally in your device's browser using JavaScript. No data is ever transmitted.
What's the maximum text length?
Theoretically, a QR code can store up to about 4,296 alphanumeric characters. However, the more text you encode, the smaller and denser the modules (squares) become, making it harder for low-resolution cameras to scan.
