Privacy Policy
Vortex (Android, Android TV, Android Auto, iPhone and iPad. Android package com.quada.vortex)
This privacy policy applies to Vortex (the "App") provided by Quad-A Digital ("we"). The App is a music player that plays music stored on your device, NAS or cloud storage. Please read it before using the App.
1. Your music files
The App reads music files directly from the device folders, NAS / PC (SMB) shares and cloud storage that you register, and plays them. Your music files and their contents are never uploaded to our servers. No account sign-up is required.
2. Data stored on your device
The following data is, as a rule, stored only on your device (it is not sent to our servers, except for the optional sync described below).
- Registered folders and the library (tag information such as title, artist, album, genre and artwork)
- Playback history and positions, favorites, playlists and the play queue
- Equalizer, display and other settings, and lock (PIN) settings
- Connection settings for NAS (SMB), WebDAV and Emby / Jellyfin (user name, password, etc.) and sign-in tokens for Dropbox and Google Drive. These are stored encrypted on the device and used only to communicate with the server you set up
3. Connecting to cloud storage and servers
These connections are made only when you set them up yourself, and all of them are read-only. The App never changes or deletes files in your cloud storage.
- Dropbox … Uses only
account_info.read(shows the connected account name),files.metadata.read(lists folders and shows file names and sizes) andfiles.content.read(streams songs for playback) - Google Drive (beta) … Uses
drive.readonlyto list and play songs in your Drive. Sync usesdrive.file, which only allows access to the sync files the App creates - WebDAV, NAS (SMB), Emby / Jellyfin … The App communicates only with the server you enter
Data from Google Drive and Dropbox is used only to provide user-facing features in the App (browsing, playback and sync) and is never sent to or stored on our servers. The App's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. See also the Quad-A Digital privacy policy for all apps.
4. Sync between devices (optional)
- Android … Only when you turn on Google Drive sync, playback history and positions, favorites, playlists, registered folders and connection settings are saved to the "Vortex Sync" folder in your own Google Drive
- iPhone / iPad … When iCloud sync is on, the same kind of data is saved in your iCloud
- Nothing is sent to our servers. To stop syncing, turn it off in the App's settings and delete the sync data in your cloud storage if needed
5. Free trial and purchase (Pro)
- Firebase (Google) … Used to manage the 7-day free trial and purchase status. On Android, the device identifier (Android ID) and, if you sign in with Google, your Google account identifier (Firebase Authentication) are used; on iPhone and iPad an anonymous identifier (Firebase Anonymous Authentication) is used. Information such as the trial start date is recorded in Cloud Firestore
- Google Play Billing / App Store (StoreKit) … Used to purchase Pro (one-time purchase) and to verify the purchase. Payment information is handled by each store and is never received by us
6. Ads
The free version shows ads served by Google AdMob. AdMob may use device information such as the advertising ID to serve and measure ads. Ads are not shown once you buy Pro. For details, see Google's advertising policies.
7. Crash reports
The iPhone and iPad version uses Firebase Crashlytics to fix bugs. When the App crashes, it sends the device model, OS version and error details. The contents of your music files and your playback history are not included.
8. Permissions
- Folder access … Used to read songs in the folders you choose (on Android, access is granted only to the folders you pick)
- Local network / Wi-Fi state … Used to connect to NAS (SMB), WebDAV and Emby / Jellyfin, and to find NAS devices on the same network
- Microphone (RECORD_AUDIO, Android) … Android requires this permission for the visualizer to analyze the audio being played. The App never records, reads or sends microphone audio
- Photo library (iPhone / iPad) … Used when you choose artwork images
- Notifications, foreground service and wake lock … Used to keep playing in the background and to control playback from notifications and the lock screen
- Biometrics (fingerprint / face) … Used to unlock the App. Authentication happens only on the device
9. Sharing with third parties
We do not sell or provide your information to third parties, except as required by law. The services above (Google Firebase, Google AdMob, Google Play, App Store, Dropbox and Google Drive) are used only as needed to provide the App.
10. Deleting your data
Uninstalling the App (or clearing its data) deletes the settings, library and connection settings stored on the device. Your music files stay where they are. Google Drive sync data can be removed by deleting the "Vortex Sync" folder. You can revoke the App's access to Dropbox and Google Drive at any time by disconnecting in the App or from each service's account settings. To request deletion of trial or purchase records, please contact us below.
11. Children's privacy
The App is not directed at children under 13. We do not knowingly collect personal information from children under 13.
12. Changes to this policy
We may update this policy as needed. Significant changes will be announced on this page or in the App. The updated policy takes effect when it is posted on this page.
