Open-source components — Pyfone for Android
Ready-to-publish attribution page. Host it on the company domain (alongside the
privacy policy and terms of use) and point LegalLinks.LICENSES (https://pyfone.com/legal/open-source/) in
LicensesSection.kt at it.
Why it has to exist: the components below are redistributed in binary form inside the app. BSD-3-Clause requires their copyright notice to be reproduced in “the documentation and/or other materials provided with the distribution”, and Apache-2.0 §4 requires the licence text and attribution notices to reach the recipient. Publishing this page satisfies both without putting the list in the app UI.
Keep it in step with native/build-android.sh and gradle/libs.versions.toml —
the four native components are compiled from vendored sources and appear in no
dependency graph, so nothing will flag them if they drift.
