PlumFM Privacy Policy

Last updated: September 26, 2026

PlumFM is a Last.fm client for iPhone. It has no servers, no accounts of its own, no analytics, no ads and no tracking. Your data lives in two places: your Last.fm account and your iPhone.

Your Last.fm account

You log in on Last.fm’s own website. PlumFM never sees your password. Last.fm gives PlumFM a session key, which is stored in the iOS Keychain. Your Last.fm username is stored in the app’s settings on your iPhone.

Logging out removes the session key and username from your iPhone.

What PlumFM sends, and to whom

Last.fm. PlumFM talks directly to Last.fm’s API to:

• load your profile, scrobbles, top charts, loved tracks and friends
• download your full scrobble history to your iPhone, so Insights can work on it
• love and unlove tracks, and submit scrobbles, when you ask it to
• look up artists, albums and tracks, and run your searches

Last.fm handles that data under its own privacy policy.

Deezer. To show artist photos, PlumFM sends artist names to Deezer’s public API and loads the photos Deezer returns. No account or personal information is involved. Deezer’s privacy policy applies.

catcatplum.com. PlumFM loads its roadmap from catcatplum.com, which is hosted on GitHub Pages. Nothing about you is sent. GitHub’s privacy statement applies.

Like any app on the internet, these services can see your IP address. Every request also identifies the app as PlumFM, with its version number.

Apple Music

If you connect Apple Music, PlumFM reads your recently played songs, and checks your music library for when a song was last played, so you can pick songs to scrobble. Songs are sent to your Last.fm account only when you tap to scrobble them. PlumFM also looks up the artists, albums and tracks you open in the Apple Music catalog, under Apple’s privacy policy.

You can disconnect Apple Music in PlumFM’s Account. Catalog lookups continue while PlumFM has access to Apple Music; turn off access in iOS Settings to stop them.

Stored on your iPhone

• your scrobble history, synced from Last.fm: artist, album, track and time
• sync progress for your account
• artists, albums and tracks you opened from Search (you can clear these in Search)
• your settings, like Top Charts options and whether Apple Music is connected

This data stays on your iPhone. It’s included in your iPhone’s backups, like most app data.

If you log in with a different Last.fm account, the previous account’s scrobble history and recent searches are deleted first.

Deleting your data

Deleting PlumFM deletes your scrobble history, recent searches and settings from your iPhone. Logging out alone keeps them on your iPhone until you delete the app.

To stop PlumFM from accessing your Last.fm account, revoke it in your Last.fm settings. Data in your Last.fm account itself, like your scrobbles and loved tracks, is managed on Last.fm.

TestFlight and the App Store

If you test PlumFM through TestFlight, Apple may share crash reports and any feedback you send with the developer.

If you install PlumFM from the App Store, Apple gives the developer reports about the app as a whole, such as how many people downloaded it, and — when you’ve allowed it on your device — crash reports. That comes from Apple, not from PlumFM, and is handled under Apple’s privacy policy. PlumFM itself still collects nothing.

Feedback by email

If you use Send Feedback, your email app sends a message to hello@catcatplum.com with the PlumFM and iOS versions filled in. What you write, and your email address, are used only to read and reply to your message.

Changes

If this policy changes, the new version will be posted here with a new date.
