Privacy Policy

Last updated: October 9, 2026 · Applies to SunoHelper v1.8.0 and later

TL;DR — SunoHelper has no servers and collects nothing. It talks only to Suno, on your behalf, from your own browser. The little it remembers (preferences, download progress, which songs you already saved) stays on your device.

1. Introduction

SunoHelper ("the Extension") is a Chrome extension that helps you download and organise your Suno songs: batch MP3/WAV downloads, song info and cover art written into MP3 files, TXT/LRC lyric files, and buttons to copy a song's prompt or lyrics. This policy explains exactly what data the Extension touches and why.

2. Data We Collect

We do not collect any data. The Extension has no backend, account system, analytics or telemetry. Specifically:

No personal information (name, email, address, payment details, etc.)
No browsing history or activity on other websites
No analytics, usage tracking, crash reporting or advertising identifiers
Nothing is ever sent to a server owned or operated by us — we don't have one

3. What the Extension Does With Data on Your Device

Signing in to Suno's API: To call Suno's API as you, the Extension needs the short-lived session token that Suno's own sign-in system issues to your browser. It obtains it from the open suno.com tab — from Suno's sign-in library, or from Suno's session cookie on suno.com, refreshing it through Suno's own sign-in endpoint the same way the website does. The token is used only for requests to Suno, kept in memory for at most a few minutes, and never written to disk or sent anywhere else. Your password is never seen, read or stored.
Song information: Song lists, titles, artists, cover art, lyrics and style prompts are read from Suno's official API to show them in the Extension and to write them into the files you download. This information is held in memory while you use the Extension.
Download allowance: Suno limits how many songs an account can download each month. To show how many downloads you have left and warn you before a batch would exceed them, the Extension reads the download-allowance numbers from your Suno billing information. It reads only those numbers; no payment details are read or stored.
Unlocking songs: A song that is not yet unlocked for download is unlocked only after you confirm it in the Extension's own confirmation dialog, using the same request as the Download button on suno.com. It uses one of your Suno downloads, exactly as downloading on suno.com would.
Downloads and tags: Audio files come directly from Suno's servers to your computer through Chrome's download manager. When "Tags & cover" is on, the MP3 is assembled in your browser (in a hidden extension page) with title, artist, cover, lyrics, style and date written in, then saved. Files that carry Suno's Content Credentials (C2PA) are left untouched. Nothing passes through any server of ours.
Copy buttons on suno.com: The Extension adds small "copy prompt / copy lyrics" buttons next to song titles on suno.com, and a toolbar on song pages. Clicking one reads that song's prompt or lyrics from Suno and places it on your clipboard. The Extension never reads your clipboard. These buttons can be turned off in the popup.

Stored locally with `chrome.storage.local` (never leaves your browser)

Preferences: language, audio format, export options (tags, TXT, LRC), last workspace, plan choice, whether the suno.com buttons are shown.
Download queue: song IDs, titles and status of the current batch, so it can resume after the browser restarts. Replaced when you start a new batch; removable with "Clear".
Download history: the IDs of songs you downloaded and when, so the Extension can show which songs are already unlocked and won't spend downloads again.
Monthly unlock count: the IDs of songs unlocked through the Extension in the current month, used for the "downloads used" counter.
Detected plan: your Suno plan name (e.g. Pro), cached for 12 hours.

All of this is deleted when you remove the Extension from Chrome. The download queue can also be cleared at any time with the "Clear" button in the popup.

4. Permissions Explained

activeTab: Read the address of the Suno tab you are on when you open the popup, so the Extension knows which page (library, playlist, style, song) to list.
scripting: Run small scripts inside your open suno.com tab to obtain Suno's session token, make requests to Suno's API from that page, read song links on the page as a fallback, and fetch audio and cover bytes for tagging — the same way suno.com itself does.
storage: Keep the preferences, queue, history and counters listed above on your device.
downloads: Save MP3/WAV files and TXT/LRC lyric files to your Downloads folder.
alarms: Keep a long batch download running. Chrome stops idle extension background processes; a timer wakes the Extension to continue the queue. It exists only while a batch is running and is never used for tracking or scheduled network activity.
offscreen: Open a hidden extension page used only to assemble tagged MP3 and lyric files in memory and hand them to Chrome's download manager (the background process cannot create downloadable files itself). It has no network or tracking role.
Host permissions (suno.com and *.suno.com): Talk to Suno's website, API and sign-in servers, and show the copy buttons on suno.com. The Extension runs on no other website.

The Extension does not request the cookies, tabs, history, webRequest or clipboardRead permissions, does not read your browsing history, and does not run on any site other than Suno.

5. Third-Party Services

The Extension communicates only with Suno's own services (suno.com, its API, sign-in and content-delivery/storage hosts that Suno's API points to). It contains no third-party analytics, advertising or tracking code, and no remotely hosted code. The Ko-fi link in the popup is an ordinary link that opens only if you click it.

6. Data Sharing

We do not sell, trade, share, or transfer any user data to any third party, under any circumstances. We do not use any data for advertising, creditworthiness or any purpose unrelated to the Extension's features.

7. Data Security

Because nothing is sent to us, there is no server-side data to breach. Requests to Suno use HTTPS. Session tokens are held in memory only and are never logged or stored.

8. Children's Privacy

The Extension does not knowingly collect any data from anyone, including children under the age of 13.

9. Changes to This Policy

We may update this Privacy Policy when the Extension changes. Changes are posted on this page with a new "Last updated" date.
