YAMP Privacy Policy

Effective date: November 11, 2026

YAMP (“Yamp”, “the app”) is a free, open source music player available at https://github.com/Julius-IX/yamp. This policy explains what data the app handles, where it goes, and how you can remove it.

In short: YAMP has no server and no developer-run backend. Nothing is sent to the developer. Your library stays on your device, and goes to a cloud service only if you choose to connect one. Features such as streaming, downloads and radio contact third-party services directly from your device, see “Other services YAMP connects to” below.

Data stored on your device

YAMP stores its data in the app data folder of your device, in a local database. This includes your library (likes, playlists and followed artists), your settings, your downloaded songs, the folders you add as local music, and your listening statistics. Listening statistics stay on your devices and can be turned off in the settings.

This data stays on your device unless you turn on cloud sync, described below. The developer cannot see it.

Optional cloud sync (Google Drive and OneDrive)

Cloud sync is off until you sign in to a service yourself. If you do, the following applies.

Google Drive

• What the app accesses: YAMP requests only the scope https://www.googleapis.com/auth/drive.appdata. This gives access to a hidden folder in your Google Drive that only YAMP can see. YAMP cannot see, read, or change any of your other Drive files.
• What is stored there: your YAMP library (likes, playlists and followed artists) and the sections of your settings that you choose to sync.
• What is stored on your device: a refresh token and your account name, in the file cloud_tokens.json in the app data folder. Access tokens are kept in memory only and are discarded when the app closes.

OneDrive

• What the app accesses: YAMP requests the Microsoft Graph permissions Files.ReadWrite.AppFolder and offline_access. This gives access to a dedicated app folder in your OneDrive and does not give access to your other files.
• What is stored on your device: the same as for Google Drive: a refresh token and your account name in cloud_tokens.json.

Other services YAMP connects to

Some features work by your device contacting a third-party service directly. The developer does not receive these requests, and each service handles them under its own privacy policy:

• YouTube and YouTube Music: searching, streaming and downloading music, using the tools yt-dlp (desktop) and youtubedl-android (Android). Your search terms and the songs you play are sent to YouTube.
• Radio Browser: finding internet radio stations by search or tag.
• GitHub: checking for and downloading updates to the app and to yt-dlp.
• Discord: if you enable Rich Presence on desktop, what you are listening to is passed to the Discord app running on your own computer.

Data collection and sharing

• The developer does not collect, receive, or store any of your data, including your Google or Microsoft account data.
• YAMP does not sell, share, rent, or transfer your data to any third party.
• Data from your Google or Microsoft account is sent only to that service’s own APIs, to read and write the app’s folder, and to nowhere else.
• YAMP does not include advertising or analytics, and does not track you.
• The in-app log (Settings > Debugging > Logs) stays on your device.

Google API Services User Data Policy

YAMP’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Retention and deletion

You can remove your data at any time:

1. Sign out of the service in YAMP’s settings, or delete cloud_tokens.json from the app data folder, to remove the stored tokens from your device.
2. Revoke access for YAMP in your account:
   • Google: https://myaccount.google.com/permissions
   • Microsoft: https://account.live.com/consent/Manage
3. Delete the synced data by removing YAMP’s app folder from your Google Drive or OneDrive, or by uninstalling the app and deleting its app data folder.

Data in your cloud account is stored under your own account and counts against your own storage. The developer has no access to it.

Children

YAMP is not directed at children and does not knowingly collect any personal information.

Changes to this policy

If this policy changes, the updated version will be posted at this location with a new effective date.
