I did not find anything about this cool office solution on F-Droid.org.
F-Droid is an alternative to Google Play Store which features open-source apps. As I see, you do publish your code as open-source versions. Is there a way you could publish this on F-Droid, too?
F-Droid also has a community forum which could be involved for that task.
Please consider having a look: f-droid.org
