Privacy policy.
The current policy is: nothing is collected.
The short version
OhmTune collects no data. None.
Silo Systems receives no recordings, audio features, take names, keeper choices, settings, or usage analytics from the app. OhmTune has no account, telemetry, advertising IDs, or app-operated crash reporting. Your recordings and settings are stored locally on your Mac.
Pitch correction, diatonic harmony, vocal separation, and audio export run on your Mac using native Apple frameworks. The vocal-separation model is bundled inside the app. There is no cloud component, server, or OhmTune account.
What we don't have, and therefore never see
The app sends no audio, content, identifiers, session history, or diagnostics to Silo Systems. If you separately email support, the message and any files you choose to attach are information you send through your email provider, not background collection by the app.
A native app, without a local server
The interface is native SwiftUI. Audio processing and separation run inside the app using Apple frameworks, including Core ML. OhmTune has no web backend or local listening port, and its App Store sandbox entitlements do not permit app-initiated network connections.
Downloads and links
OhmTune does not download model weights. Its processing works offline after installation, and the app itself opens no network connections. If you choose Share take, macOS and the service you pick (such as AirDrop, Mail, or Messages) send that take where you direct it; Silo Systems receives nothing. These separate system services may also use a connection:
- App Store installation and updates. Apple delivers the app and its updates through the App Store, subject to Apple's privacy practices. After a saved take the app may also show Apple's standard rating prompt; any rating or review you choose to submit is sent to Apple through the App Store, and the app itself sends nothing to Silo Systems.
- Links you click. If you click an external link inside the app, your default browser handles the request. OhmTune is not involved.
Permissions we request, and why
- Microphone. Capture your vocal input for real-time pitch correction and harmony.
- Files you choose. Import and export access outside the app's own storage is granted through macOS file-selection and sharing controls.
Recording starts only when you choose Start singing and grant microphone permission. OhmTune does not request Camera, Contacts, Location, or Full Disk Access. It can access its bundled resources and its own sandbox storage without asking for access to unrelated files.
On-device data you create
Recordings are saved in Documents/OhmTune Takes within the app's sandbox. Names and keeper choices stay local, and settings use local macOS preferences. Exports live wherever you choose to save them. Removing the app does not automatically remove your exported files; you control those files in Finder.
On-device components
These components process audio locally; they are not remote services:
- Native audio processing. Apple audio frameworks perform pitch correction, harmony playback, recording, and export.
- Spleeter 2-stems. The bundled model runs through Core ML to separate vocals and accompaniment from an imported track.
Children's privacy
OhmTune is rated 4+. Because no personal data is collected from any user, no special treatment is required for users under 13. Same policy applies regardless of age: nothing collected.
Changes
If we ever materially change how OhmTune handles data, we will publish an updated version of this page, announce the change prominently in the release notes, and require explicit consent in-app before any new collection begins. The current policy is: nothing is collected.
