Frequently Asked Questions
- How does the built-in QR Code generator operate?
- Text and URLs are encoded client-side as a QR Code with error-correction level M. Scanning still depends on size, contrast, focus, distance and camera.
- Are messages stored on external database servers?
- No. State remains strictly within the local browser memory session.
Technical Methodology & Display Science
Typography scales with the viewport. Check the message at the real venue because distance, acuity, glare, character size and contrast affect legibility.
QR content is encoded locally with error-correction level M. Redundancy helps, but cannot guarantee scanning through glare, blur, excessive distance or angle.
Themes offer contrast options; check legibility for the chosen colors and text size. There is no claim of comprehensive WCAG AAA certification.
