It ships with its own application ID, so it installs alongside upstream RikkaHub on the same device, with separate data and no automatic import from the upstream app.

After that, the built-in updater detects your device ABI and offers matching updates.

The listed OrcaRouter gateway is paid promotion only, not affiliated with the project.

Updates also require the project's own signing key - an APK signed with a different key cannot update an existing install.

Sensitive tools (workspace, clipboard, calendar, screen time) sit behind approval boundaries, and Firebase only enables if you opt in.

Standard AGPL copyleft - worth knowing before forking.

Assistant memory retrieval is embedding-based with a lexical fallback.
