Do these QR codes expire?

No. They are static codes: the content is stored in the pattern itself, with no redirect through our servers, no tracking and no expiry. They work for as long as the content stays valid.

Is what I type sent to a server?

No. The code is generated in your browser. Passwords, payment IDs and contact details never leave your device.
