Privacy Policy for MixScout & MixScout Companion Chrome Extension
Last updated: November 8, 2026
MixScout ("we", "our", or "us") operates the MixScout Web Studio (https://mixscout.app) and the MixScout Companion — DJ Playlist Harmonic & Set Coach Chrome Extension. We are committed to protecting your privacy. Neither the MixScout Companion Chrome Extension nor the MixScout Web Studio sells, rents, or monetizes your personal data or browsing history.
1. What Data the Chrome Extension Accesses
When you open a supported music playlist page or click Sync in the MixScout Companion Side Panel, the extension accesses only:
- Publicly visible playlist track metadata: Song titles, artist names, track durations, and visible track order on supported music websites (Spotify Web Player, YouTube, YouTube Music, Beatport, SoundCloud, Apple Music, Deezer, TIDAL, and Bandcamp).
- User interface preferences: Your chosen interface language (
ENorES), whether on-page BPM/Key badges are enabled, your locally saved Collector Basket tracks, and tracks marked as "Played Tonight".
The extension does not read or collect your account passwords, authentication cookies, payment information, personal communications, or general web browsing history.
2. How Data Is Stored
- Local Device Storage Only: All resolved track BPM and Camelot harmonic key cache entries, language settings, Pinned Crate items, Collector Basket tracks, and Played Tonight lists are stored strictly on your device using browser local storage (
chrome.storage.local). - Studio Handoff: When you explicitly click "Open Full Crate in MixScout Studio", the extension transfers your current playlist track list into your local browser storage on
https://mixscout.app/dashboardso you can inspect and arrange your crate in the full studio view.
3. How Data Is Used & Third-Party Catalog Services
To display tempo (BPM), Camelot harmonic key (1A–12B), and 30-second audio previews for songs detected in your playlist, the extension queries public music catalog endpoints:
- Deezer Public API (
api.deezer.com) & Apple iTunes Search API (itunes.apple.com): Public song title and artist strings are sent solely to look up public catalog BPM, ISRC, album artwork, and 30-second preview audio clips. No user identifiers, cookies, or personal information are transmitted with these catalog lookups.
4. Data Sharing & Chrome Web Store User Data Policy Compliance
We do not sell, transfer, or share any user data with third parties, advertising networks, data brokers, or analytics providers. The use of information received from Google APIs and Chrome Extension APIs adheres strictly to the Chrome Web Store User Data Policy, including the Limited Use requirements:
- Data is not sold to third parties.
- Data is not used or transferred for purposes unrelated to the extension's single purpose (analyzing music playlists for tempo, harmonic key compatibility, and transition order).
- Data is not used or transferred to determine creditworthiness or for lending purposes.
5. Data Retention and Deletion
All extension state stays locally on your computer. You can clear your Collector Basket or reset your "Played Tonight" history at any time directly inside the MixScout Side Panel, or remove all locally cached data immediately by uninstalling the MixScout Companion extension from Chrome.
6. Changes to This Policy
If we update this Privacy Policy, we will post the revised version on this page (https://mixscout.app/privacy) and update the "Last updated" date above.
