About

Squarelatch is a small independent project run by Hydr₳, an individual operator: a QR code generator that is genuinely free, works without an account and does not deactivate codes.

How it is built

• Plain HTML, CSS and JavaScript. No trackers, ads, cookies or third-party scripts.
• Codes are generated in your browser with the open-source qrcode-generator library by Kazuhiko Arase (MIT licence).
• The PDF and SVG exports and the scan check are our own code.

Contact

You can contact the operator by email at rdalio321@gmail.com.
