Licences

The work of other people that this website carries, and under which licence. Three items, and that is the whole list.

Reading a QR code

jsQR — Apache License, Version 2.0. Contributors: Cosmo Wolfe and Jeff Nelson, github.com/cozmo/jsQR.

It is loaded only on the page that scans, and only where the browser cannot read a code by itself. Safari has no BarcodeDetector; this fills that gap and nothing else. The licence.

The two typefaces

Barlow — SIL Open Font License 1.1. Copyright 2017 The Barlow Project Authors, github.com/jpt/barlow. The licence.

Public Sans — SIL Open Font License 1.1, a fork of Libre Franklin by the United States Web Design System. Copyright 2015 The Public Sans Project Authors, github.com/uswds/public-sans. The licence.

Both are served from this server and never fetched from anybody else. A page that pulls a font from a third party tells that third party who is reading it, and that is a visit nobody asked for.

What is not on this list

Everything else here was written for this service. The server runs on Node's standard library and installs nothing: there is no dependency to name. The QR codes on the pages are drawn by code of our own rather than by a library.

“QR Code” is a registered trademark of DENSO WAVE INCORPORATED.

This page covers the website. The iPhone and Android apps carry other people's work as well — Google's WebRTC under the three-clause BSD licence on both, and on Android the libraries the app is built from — and each names it in the app, under This phone › Licences.
