TL;DR: Your data stays on your device by default. Cloud sync is entirely opt-in. Optional anonymous analytics only if you enable them. Code is reviewed by the Chrome Web Store team and available for security audit upon request.
1. Where Your Data Lives
Everything stays on your device by default. Your entire Suno library, download history, custom names,
manual lineage links, and all curation data is stored in your browser's IndexedDB.
Unless you opt into cloud sync, no music data leaves your device. See Section 1b for details on optional cloud sync.
What's Stored Locally:
Clip Metadata: Song titles, creation dates, model versions, lyrics, durations
Syncs between the extension and the Explorer Go web app
Linked to your Google account via OAuth
Paid tier (subscribers):
Library metadata: Song titles, creation dates, model versions, lyrics, and durations
Stored in a compressed format — no audio files are ever uploaded
What we DON'T store in the cloud:
Audio files or recordings
Your Suno authentication token
Browsing history or extension activity
Google Sign-In:
We use Google OAuth to authenticate you — we receive your email and display name
We do not access your Google Drive, Gmail, or any other Google services
Your Google credentials are handled entirely by Google's servers
Your control:
Cloud sync is entirely opt-in — Explorer works fully offline without it
You can delete all cloud data from the extension settings at any time
Unsynced data stays local and is never uploaded
2. Your Suno Credentials
Your Suno authentication token is stored in your browser and used to fetch your library from Suno's servers.
Chrome extension: Requests go directly from your browser to Suno — your token never leaves your device.
Web app (no extension): Requests are proxied through our server to handle browser security restrictions (CORS). Your token is sent over HTTPS, used for that single request, and never stored or logged on our server.
In both cases, we don't log your token and we don't know your Suno username unless you enable analytics (see below).
3. Optional Analytics
We offer completely optional anonymous analytics for community insights. This is OFF by default. You choose your privacy tier:
Privacy Tier 1: Count Only (Default)
Contributes to the global user count
That's it. Literally one number.
Privacy Tier 2: Aggregate Stats
Anonymous genre distribution (e.g., "35% Electronic, 25% Rock")
Model version usage (e.g., "v3.5 used by 60% of users")
Library size percentiles (e.g., "You're in the top 10% of power users")
No identifying information. Just aggregated numbers.
Privacy Tier 3: Public Curation
For users who want to share curated collections publicly
You explicitly choose which songs to make public
Creates a shareable link to your curated library
Still doesn't include your Suno username or email
How Analytics Work:
Your user ID is hashed with SHA-256 before submission (one-way, can't be reversed)
Data is submitted to Supabase (secure, encrypted database)
Rate-limited to 1 submission per 24 hours
Row-Level Security (RLS) prevents anyone from reading individual submissions
Only aggregated, anonymized data is publicly visible
4. What We DON'T Collect
Your IP address
Your Suno username or email
Your actual song files or audio
Browsing history or other extension activity
Device fingerprints or identifiers
Cookies or tracking pixels
5. Third Parties
The only third parties involved are:
Suno.com: Direct API calls from your browser (not proxied through us)
Supabase: If you enable analytics (anonymized stats) or cloud sync (curation/library data)
Google: Only if you sign in for cloud sync (OAuth authentication)
We don't use Google Analytics, Facebook Pixel, or any tracking services. We don't sell data. Your library data is only stored externally if you explicitly opt into cloud sync.
6. Data Export & Deletion
You have full control over your data:
Export: Use "Data Management" → "Full Backup" to export everything as JSON
Delete: Use "Data Management" → "Clear Index" or uninstall the extension
Selective Delete: Remove individual songs, custom names, or links from Data Management
7. Code Transparency
Suno Explorer is proprietary software, but transparency is a core value. Here's how we ensure trust:
Every release is reviewed by the Chrome Web Store team before publication
Source code is available for security audit upon request
Extension code ships unobfuscated in the Chrome Web Store package — you can inspect it yourself
This privacy policy details exactly what data goes where
If you're a security researcher or have concerns about how your data is handled, reach out and we'll gladly provide source access for review.
8. Security Measures
Local data protected by your browser's built-in security
No network requests except to Suno.com and (optionally) Supabase for analytics or cloud sync
SHA-256 hashing for user IDs in analytics
Row-Level Security (RLS) in Supabase prevents unauthorized access to cloud data
Server-authoritative versioning for cloud sync — no conflicts, no data loss
Rate limiting prevents spam/abuse
Google OAuth for cloud sync — we never see or store your Google password
9. Children's Privacy
Suno Explorer is not directed at children under 13. We don't knowingly collect data from children.
If you're under 13, please don't use this extension.
10. Changes to This Policy
We'll update this page if our privacy practices change. Check back occasionally.
We'll never make changes that compromise your privacy without clear notice.
11. Questions?
If you have concerns about privacy, want to request data deletion, or just want to chat about how we handle your data, reach out. We're happy to explain anything.
12. Legal Stuff
Data Controller: Independent developer (not a company)
Jurisdiction: United States
Contact: See extension listing for developer contact
Bottom Line: I built Suno Explorer to scratch my own itch. We're not in the business of collecting or selling data. Your music library is yours. We just help you explore it better.
