Overview
Huqqs is a music visualizer and live lyrics app for iOS. It listens to music playing around you, identifies songs, displays synchronized lyrics, and generates real-time visual effects driven by audio analysis. Some data stays only on your device, some data persists locally so the app can keep your heard-song history, and some data is sent to service providers that power song recognition, lyrics, cloud scene direction, analytics, and optional bug reports.
Information we access
Microphone audio
Huqqs uses your device's microphone to identify songs playing nearby via Apple's ShazamKit framework. Huqqs does not record or store raw microphone audio. Audio is processed in real time for song recognition and live visual response.
Song metadata and heard-song history
When a song is identified, Huqqs may receive metadata such as the title, artist, ISRC, track key, and duration. This information is used to fetch lyrics, generate scene direction, and populate your heard-song history. Huqqs stores heard-song history locally on your device in a rolling 30-day window so your heard songs persist between launches unless you clear them or remove the app.
Audio analysis and derived features
Huqqs performs real-time FFT, beat detection, and other audio analysis on-device to drive visuals. These runtime values are transient. However, derived audio features such as energy, tempo, and band activity may be sent to Huqqs cloud services to generate visual plans and lyric-related responses.
User preferences
Settings such as preferred visual stage, mood, translation preferences, menu choices, color selections, dancing pet companion selection, pet enabled/disabled state, and pet on-screen position are stored locally on your device. This data stays on your device unless you choose to submit a bug report that includes diagnostics.
AI and scene direction
Huqqs does not currently use Apple's on-device Foundation Models language model in production. Scene direction currently comes from Huqqs cloud plan generation and on-device rule-based systems. Huqqs does not use your microphone audio to train a custom model.
Third-party services
Huqqs communicates with the following third-party services:
| Service | Purpose | Data sent |
|---|---|---|
| ShazamKit | Song identification | Audio fingerprint (not raw audio) sent to Apple for recognition |
| Huqqs Cloud API | Scene direction, lyrics bootstrap, translation support, rate limiting | Song metadata, device identifier, country/region, derived audio features, translation preferences |
| Musixmatch | Lyrics and translation retrieval | Song metadata such as title, artist, ISRC, duration, and Apple Music identifiers when available. Per Musixmatch terms, lyrics text is never cached server-side — only plan metadata and translations are cached. |
| LRCLIB | Lyrics retrieval fallback | Song title, artist name, and duration |
| Firebase Crashlytics | Crash reporting and error telemetry in production builds | Crash logs, device model, OS version, and diagnostic event data |
| Google Cloud Firestore | Cloud caching and optional bug report storage | Cached cloud request data and any bug report payload you choose to submit |
These services have their own privacy policies:
Data storage and retention
- Huqqs does not require user accounts or sign-in.
- Heard-song history persists locally on your device in a rolling 30-day window until you clear it or delete the app.
- User preferences persist locally between sessions.
- Raw microphone audio is not recorded or stored by Huqqs.
- Runtime audio-analysis values are transient, but derived audio features may be transmitted to Huqqs cloud services for plan generation.
- Huqqs cloud bootstrap request data may be cached remotely for performance and reliability.
- If you voluntarily submit a bug report, the report contents, diagnostics, and redacted logs may be stored remotely so we can investigate the issue.
- Huqqs does not sync your local heard-song history to iCloud or another Huqqs account service.
Data sharing
Huqqs does not sell or rent your personal information. Huqqs shares limited data only with the service providers needed to identify songs, fetch lyrics, generate cloud scene direction, process analytics/error telemetry, and store optional bug reports.
Children's privacy
Huqqs is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13.
Your rights
Most Huqqs data lives locally on your device, and you can remove it by clearing heard-song history in the app or deleting the app. If you submitted a bug report and want it removed from our systems, email support@huqqs.com with enough detail for us to locate it, such as the approximate submission time, app version, and device model.
Changes to this policy
We may update this privacy policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of Huqqs after changes constitutes acceptance of the revised policy.
