Privacy Policy
Effective
Norrklang is a music player for Navidrome and Subsonic-compatible servers, published by Koeda Studio for Android Automotive OS. It is a client for a server you choose and control. This policy describes what the app itself does with data.
What the app stores, and where
All data the app stores stays on your device:
- Server connection details — the server address, your username, and a derived authentication token (never your password; the password is used once at sign-in to compute the token and is not retained). The token is encrypted with a hardware-backed Android Keystore key. App data is excluded from device backups and device-to-device transfers.
- Playback state — the last played track and position, so playback can resume after a restart.
- Caches — library listings and cover art fetched from your server, kept per-account and cleared when you sign out or switch accounts.
Signing out deletes the stored connection details and playback state. Uninstalling the app deletes everything.
What the app sends, and to whom
The app communicates only with the server address you configure:
- browsing and search queries, to show your library
- audio streaming requests, to play music
- playback reports (“scrobbles”), so your server can track play counts
- playlist updates you trigger (e.g. the “liked songs” button in the car)
Norrklang has no analytics, no advertising, no crash reporting, and no third-party services. The developer receives no data from the app. What your server operator logs is governed by that server’s own policies — if you use someone else’s Navidrome server, ask them.
Data shared with the car
On Android Automotive OS, the car’s media interface displays your library metadata (titles, artists, cover art) and playback state. That data stays within the car’s media system; the app grants it no access to your credentials.
Children
Norrklang is not directed at children and collects no personal data from anyone.
Changes
Changes to this policy will be published on this page and noted in the project changelog with a new effective date.
