## Common questions

**Does it cost anything?** No. Completely free, no subscription.

**Do QR codes expire?** No. Static QR codes encode data directly and work indefinitely as long as the destination (e.g. a URL) is live.

**Is it private?** Yes. No data leaves your device. There is no server-side processing, no cookies, and no analytics.

**What browsers are supported?** Any modern browser with JavaScript enabled. Camera scanning requires a device with a camera and a browser that supports `getUserMedia`.

**Who made this?** GK Nguyen — Pocket QR Code Tools is an open-source personal project.
