Privacy Policy
Last updated: March 28, 2026
Overview
Tremor DJ ("Tremor", "the App") is developed by MindArray. We are committed to protecting your privacy. This policy explains what data the App accesses and how it is used.
Data Collection
Tremor does not collect, store, or transmit any personal data to external servers.
All audio processing, AI analysis (BPM detection, stem separation, key detection, music classification), and DJ performance data stays entirely on your device.
Device Permissions
Tremor may request the following permissions:
- Music Library — To browse and load tracks from your Apple Music or local library for DJ mixing.
- Microphone — For live mic input during mixing, voice effects, and Shazam song identification.
- Camera — For capturing video during live DJ performance for video mixing and streaming.
- Local Network — For syncing playback state with nearby Tremor devices and AirPlay video streaming.
All permissions are optional. The App functions without any permissions granted (you can load files from the Files app instead of the music library).
Third-Party Services
- Apple Music — If you have an Apple Music subscription, Tremor can access the catalog via Apple's MusicKit framework. Apple's privacy policy applies to Apple Music data.
- Shazam — Song identification uses Apple's ShazamKit. Audio fingerprints are processed by Apple's servers. Apple's privacy policy applies.
- SoundCloud — If you choose to upload recordings to SoundCloud, your SoundCloud account credentials are managed by SoundCloud's OAuth. MindArray does not store your SoundCloud credentials.
- RTMP Streaming — If you enable live streaming, video/audio is sent to the streaming platform (YouTube, Twitch, Facebook) you configure. MindArray does not operate or access these streams.
Analytics
Tremor uses Apple's built-in MetricKit framework to collect anonymized performance metrics (crash reports, hang diagnostics). This data is collected and managed by Apple according to their privacy policy. MindArray does not use any third-party analytics SDKs.
Data Storage
All app data (cached analysis results, stem files, recordings, settings) is stored locally on your device in the app's sandboxed container. You can clear cached data from iOS Settings > Tremor.
Children's Privacy
Tremor does not knowingly collect information from children under 13. The App does not require account creation or personal information to function.
Changes
We may update this policy from time to time. Changes will be posted on this page with an updated date.
