Privacy Policy
Vision Music Visualizer collects no data about you. Your audio is never recorded, never stored, and never uploaded.
Microphone
The app uses your device's microphone for one purpose: analyzing the music playing around you, in real time, to drive the visualizations. Audio is processed on your device in memory. It is never recorded and never stored. The app has no ability to save audio.
Song identification
While you're listening, the app can identify the song that's playing so it can show you the title and album art and lock the visuals to the track's true tempo. This works the way Shazam does, using Apple's ShazamKit framework:
- Your device generates a compact, irreversible acoustic fingerprint of the ambient sound and sends only that fingerprint to Apple's recognition service for matching. The fingerprint cannot be turned back into audio — speech and conversation cannot be recovered from it. Apple's handling of these requests is governed by Apple's privacy policy.
- When a song is identified, the app sends the track's standard recording identifier (its ISRC — a public catalog code, nothing about you) to Deezer's public catalog API to look up the song's tempo.
Neither request contains personal information, identifiers, or your audio, and we operate no servers of our own — nothing about these lookups is collected or retained by us.
What we collect
- No personal information
- No audio recordings
- No usage analytics or telemetry
- No location data
- No identifiers or tracking of any kind
Purchases
The optional lifetime unlock is processed entirely by Apple through the App Store. We never see your payment details, and the app stores no purchase information beyond the entitlement Apple provides to your device.
Accounts, ads, and third parties
The app has no accounts, no sign-in, no advertising, and no third-party analytics SDKs. Its only network activity is the song identification described above — anonymous fingerprints to Apple and a public catalog lookup to Deezer.
Children
Because the app collects no data from anyone, it collects no data from children.
Changes
If a future version of the app ever changes how it handles data, this policy will be updated here before that version ships, with a new effective date.
