SlimLibrary Privacy Policy

Last updated 2 November 2026

In short: SlimLibrary collects no personal data. Nothing about you or your listening is sent to the developer. The app talks to the music server you point it at, and that server is yours.

Data we collect

None. SlimLibrary has no account system, no analytics, no crash reporting, no advertising, and no third-party tracking software of any kind. The developer receives no information about you, your device, your music or how you use the app.

What is stored on your device

So that you do not have to set it up each time, SlimLibrary saves the following in the app's own storage on your device:

The address and port numbers of your music server.
The username and password for your server, if it requires them.
Your preferences, such as the player you last used and how you prefer lists sorted.

This information stays on your device and is never transmitted to the developer. Your server credentials are sent only to the server address you entered, in order to log in to it.

Deleting SlimLibrary removes all of it. There is nothing stored elsewhere for us to delete, because nothing was ever sent to us.

What the app connects to

SlimLibrary makes network connections to:

Your music server: The Lyrion Music Server you configure. This carries your library browsing, playback commands and album artwork. We do not operate this server and have no access to it — it is on your own network or wherever you have chosen to run it.
mysqueezebox.com: When your server provides artwork or icons hosted at mysqueezebox.com, typically for online music services and plugins you have enabled on your server, the app loads those images from there over an encrypted connection. This happens only because your server supplied those addresses. That service is operated by a third party under its own privacy policy, not by us.

SlimLibrary contacts no other services. It does not call home.

Children

SlimLibrary is not directed at children and collects no data from anyone, regardless of age.

Your choices

Because no data is collected, there is nothing to opt out of, no consent to withdraw and no data export to request. You can remove your stored server details at any time by deleting the app, or change them in Server Settings.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date at the top.
