Linthra

Linthra is an open-source Android music player for people who keep their music on

their own devices or self-hosted servers. It plays local files, and it streams

from self-hosted music servers such as Jellyfin and Navidrome/Subsonic — you

bring your own server and sign in with your own account.

Linthra is an unofficial community client. It is not affiliated with Jellyfin,

Navidrome, or Subsonic.

The app is still early alpha. It's usable for testing on a real device, but it

isn't production-stable and has a few rough edges. The lists below separate what

works today from what's still planned.

On privacy:

* No ads, no tracking, no analytics, and no crash-reporting or telemetry SDK.

* No account to create, and nothing phones home — streaming is the default, and

downloads only happen when you ask for them (Wi-Fi only unless you opt in to

mobile data).

* When you sign in to a server, the password is used once to get a session

token, then dropped; the token is stored encrypted and never logged.

* Open-source under the GNU Affero General Public License v3.0 or later, so

anyone can read, build, and contribute to it.

What works today:

* Local library — pick a folder with the Storage Access Framework (no broad

storage permission), scan it, and browse Songs, Albums, and Artists with

search.

* Streaming from your own Jellyfin or Navidrome / Subsonic server: test the

connection, sign in, sync, and play, including over HTTPS.

* A smart offline cache — download tracks for offline play, with a size limit
