Overview
The ShowLark Playlist Generator for Suno ("the Extension") is designed to help you generate playlists from your Suno.com account and visualize them in ShowLark. This privacy policy explains what data the Extension accesses, how it's used, and how it's protected.
Data Collection Summary
| Data Type | Collected | Stored | Sent to Our Servers |
|---|---|---|---|

What Data We Access
1. Suno Authentication Cookies
What: Session cookies from suno.com (e.g., __session, __client)
Why: These cookies are required to authenticate API requests to Suno on your behalf. Without them, the Extension cannot generate songs or browse your library.
How it's used:
- Cookies are read from your browser when you're logged into Suno
- They are used to make authenticated requests to Suno's API
- All requests are made directly from your browser to Suno's servers
- Cookies never leave your browser. They are not sent to ShowLark or any other third party
Storage: Stored locally in Chrome's extension storage (chrome.storage.local)
2. Device Identifier
What: A randomly generated UUID stored locally
Why: Suno's API requires a device identifier in request headers
How it's used:
- Generated once when you first use the Extension
- Included in headers when making requests to Suno's API
- Never sent to ShowLark servers
Storage: Stored locally in Chrome's extension storage
3. Generation History
What: Records of playlists you've generated (genre, song count, results)
Why: To show your generation history and allow re-pushing songs to ShowLark
How it's used: Displayed in the Extension popup's History tab
Storage: Stored locally in Chrome's extension storage (last 10 generations)
4. ShowLark Account Information (Optional)
What: If you sign in to ShowLark, your subscription tier and feature entitlements
Why: To enable tier-based features like higher song limits
How it's used:
- Synced from the ShowLark website when you're signed in
- Used to determine feature limits in the Extension
- If available, a ShowLark auth token is stored locally and used for direct entitlement requests to ShowLark's backend
Storage: Stored locally in Chrome's extension storage
5. Feature Usage Analytics (Collected by ShowLark Web App)
What: Anonymized usage data about extension-related features, collected by the ShowLark Visualizer web application when you use the extension with app.showlark.com — not by the Extension itself. The Extension package itself contains no analytics or tracking code.
Why: To understand how extension features are used, detect errors, and improve the product
What's tracked:
- Feature usage events (e.g., library opened, generation started, songs added to playlist)
- Success/failure status and error messages
- Aggregate counts and timing (e.g., number of songs loaded, load duration)
- Build metadata for regression detection (commit hash, branch, build time)
What's NOT tracked:
- No song content, titles, lyrics, or search queries
- No Suno authentication data (cookies, tokens, user IDs)
- No personally identifiable information
How it works: When you use extension-related features through the ShowLark Visualizer website, the web app may record anonymized usage events. These events are sent by the web page to ShowLark's analytics services. The Extension itself is not the component sending analytics data.
Storage: ShowLark servers (Supabase). Usage events are retained for 90 days; UI interaction events for 30 days.
What Data We DO NOT Collect
- Browsing history: We don't track or record what websites you visit
- Personal information: We don't collect names, emails, or other personal data through the Extension
- Audio files: Songs are streamed directly from Suno's CDN; we don't intercept or store audio
- Payment information: All payments are handled directly by Stripe/PayPal through ShowLark's website
