Eridanus — Bundled Component Notices
====================================

Eridanus's own source code is licensed under the Mozilla Public License
2.0. See LICENSE.

Eridanus ships in two build flavors (the `rnsImpl` Gradle product-flavor
dimension). Each APK bundles a different Reticulum implementation, and
the two carry different downstream terms — read this before
redistributing a build.


Kotlin flavor  —  eridanus-kotlin-*.apk
---------------------------------------

Bundles reticulum-kt (https://github.com/torlando-tech/reticulum-kt),
licensed under the Mozilla Public License 2.0 — the same license as
Eridanus's own code. No additional restrictions; the APK as a whole is
distributable under MPL-2.0 terms.


Python flavor  —  eridanus-python-*.apk
---------------------------------------

Bundles the upstream reference implementation of Reticulum (the Python
RNS, https://github.com/markqvist/Reticulum), pip-installed at build
time via Chaquopy — pinned to `rns==1.2.5` in
eridanus-rns-backend-py/build.gradle.kts. It is licensed under the
**Reticulum License** — see the LICENSE file at the root of the
upstream Reticulum repository for the authoritative text. The
Reticulum License is an MIT-derived permissive license with two
additional field-of-use restrictions:

  - The software shall not be used in any kind of system which includes
    among its functions the ability to purposefully do harm to human
    beings.

  - The software shall not be used, directly or indirectly, in the
    creation of an artificial intelligence, machine learning or language
    model training dataset.

MPL-2.0 governs only Eridanus's own files and places no restriction on
the remainder of a Larger Work (MPL-2.0 §3.3), so the two licenses
combine cleanly. However, the field-of-use restrictions above apply to
the Reticulum-licensed portion of the python-flavor APK and ride along
with any redistribution of that APK.

The python flavor also bundles:

  - Chaquopy (https://github.com/chaquo/chaquopy) — MIT License — the
    Python runtime/build system that embeds CPython into the APK.
  - CPython and the Python standard library — Python Software
    Foundation License.
  - PyCA `cryptography` (https://github.com/pyca/cryptography) —
    Apache-2.0 OR BSD-3-Clause — native crypto wheel from Chaquopy's
    prebuilt package repo, used by RNS in place of its pure-python
    fallback. Pinned to `>=42.0.0` in
    eridanus-rns-backend-py/build.gradle.kts.

All three are standard permissive licenses and impose no field-of-use
restrictions.
