My code is public domain (https://codeberg.org/anarkio/pages/src/branch/main/nostril/), but it is low quality, hacky and non-professional, so it is not worth salvaging.
Hopefully Retnull could claim the bounty with their Android client when it is ready. If not you could claim the bounty with your RebelNet platform. Or you could split it 50:50 with Retnull.
