Planium Third-Party Licenses
Planium is written from scratch in plain HTML, CSS and JavaScript — there is no framework behind it. The one thing it borrows is artwork: most of its icons come from the open-source Lucide icon library. This page reproduces that license, as its terms require, and lists exactly which icons it covers. The iPhone app additionally ships the native shell it runs in, whose licenses follow further down.

Lucide (icons)
Most of the icons in Planium are taken from, or adapted from, the Lucide icon library. Some have been modified for this project — changed viewBox, different stroke widths, wrapped as <symbol> sprites, or combined and partially redrawn. Lucide is distributed under the ISC License, reproduced below as required.

Original artwork (not from Lucide)
The following are original Planium/Softium artwork and are not covered by the license above:

The iPhone app (native shell)
The iPhone app is the same website wrapped in a native shell built with Capacitor. The components below are compiled into the app binary, so their licenses are reproduced here as those licenses require. None of this applies to the website or the installed web app, which ship no third-party code beyond the icons above.
Capacitor (app runtime)
The native shell around Planium. @capacitor/ios is the iOS runtime; it is built into the app through the capacitor-swift-pm 8.4.1 Swift package, which is the same code from the same authors.
