How it works: your text is encoded as UTF-8 into a standard QR code in your browser. Nothing is sent anywhere, and the code never expires because it contains your text or link directly (no redirect service).
Print tips: dark code on a light background scans best; inverted (light on dark) codes fail on some phone cameras. Keep the quiet zone, print at least about 2 cm (0.8") wide for short URLs, and use SVG for cover or interior layouts. Test-scan with two different phones before you publish.
