SUNO Bulk Downloader — Privacy Policy

Last updated: April 12, 2026

Overview

SUNO Bulk Downloader is a browser extension that helps you download your own songs from your SUNO account. We respect your privacy and are committed to transparency about how the extension works.

Data Collection

We do not collect, store, transmit, or share any personal data.

Specifically:

• No analytics or tracking of any kind
• No data is sent to any external server
• No cookies are read or stored by the extension
• No browsing history is collected
• No personal information is gathered

How the Extension Works

The extension operates entirely on your local device:

• Authentication token: The extension captures your SUNO session token from your browser to make API requests on your behalf. This token is stored locally in your browser's extension storage and is never transmitted elsewhere.
• Song data: Song metadata (titles, URLs) is fetched directly from SUNO's API using your authenticated session. This data stays on your device.
• Downloads: MP3 files are downloaded directly from SUNO's CDN to your local Downloads folder.
• Download history: A record of which songs you've already downloaded is stored locally to avoid duplicates. This data never leaves your device.

Permissions

The extension requests the following browser permissions:

• downloads: To save MP3 files to your computer
• storage / unlimitedStorage: To save your download queue and history locally
• alarms: To keep the download process alive during long batch operations
• webRequest: To read your SUNO authentication token from API requests so the extension can access your library on your behalf. No requests are modified or blocked.
• Host permissions (suno.com, studio-api.prod.suno.com, cdn1.suno.ai, cdn2.suno.ai): To communicate with SUNO's services and download your songs

Third-Party Services

This extension communicates only with SUNO's own servers (suno.com, studio-api.prod.suno.com, cdn1.suno.ai, cdn2.suno.ai) to access your account data and download your songs. No other third-party services are used.

Data Retention

All data is stored locally in your browser. You can clear your saved token, download queue, and history at any time using the "Clear Token & All Local Data" button in the extension popup, or by removing the extension entirely. No data persists on any external server.

Changes to This Policy

If we update this privacy policy, the changes will be posted on this page with an updated date.
