FAQ

Practical answers.

Where are generated QR files stored?

FastAPI stores them in `output/session` for quick local downloads while the app runs.

What happens after closing the app?

The session folder is cleared on server shutdown and again on the next startup.

Do QR codes expire?

These are static QR codes. Once downloaded, the image keeps working as long as the encoded content remains valid.
