MonoBand is built with privacy as a first-class feature, not an afterthought. This page explains, in plain language, what data the app handles, where it lives, and what we do with it.
The one-line version
Everything you do in MonoBand stays on your device. We don't run any servers, we don't have user accounts, we don't use analytics, and we don't embed third-party tracking SDKs. The AI model that splits songs into stems runs locally on Apple's Neural Engine.
What MonoBand can access
Audio files you import
When you import a song — from the Files app, your Music library, the Photos app (for videos), or a fresh recording — that audio is copied into the app's own sandboxed storage. iOS gates this access with the system file picker; we never read files you didn't explicitly choose.
Microphone (only when you record)
MonoBand asks for microphone access the first time you tap the record button. iOS shows the standard permission prompt, and the microphone is only active during an explicit recording session. Recorded audio is saved into the project on your device — it is not streamed or uploaded anywhere.
Photo library (optional, for cover art)
If you choose to set a custom cover image for a song, MonoBand uses the standard iOS PhotosPicker to read the single image you pick. We don't scan your library, we don't see other photos, and we don't keep any references after you've chosen.
What MonoBand does not do
- No servers. MonoBand makes no network requests for stem separation, BPM detection, key detection, transpose, or any other audio processing. All of it runs locally.
- No analytics or telemetry. We don't track which features you use, how long sessions last, or anything else.
- No third-party SDKs. No Facebook, Firebase, Google Analytics, advertising networks, or crash reporters that phone home.
- No accounts or sign-in. There is no MonoBand account because there is no MonoBand backend to sign in to.
- No ads. No banners, no interstitials, no sponsored content of any kind.
Where your data lives
Imported songs, separated stems, recordings, project metadata, playback preferences, and section markers are all stored inside MonoBand's app sandbox on your device. If you have iCloud Drive configured to back up app data, Apple may include the MonoBand sandbox in your encrypted iCloud backup — that's entirely under Apple's privacy terms and we never see the contents.
Sharing
When you tap the Share button — to send a stem, an exported mix, or a recording to Messages, Mail, Voice Memos, or another app — iOS hands the file to that app via the standard share sheet. From that point on, the receiving app's privacy policy applies.
Children
MonoBand is suitable for users of any age and does not knowingly collect any personal information from anyone, including children under 13. There is no account to create and no personal data is transmitted off the device.
Changes to this policy
If we ever change how MonoBand handles data, we'll update this page and bump the "Last updated" date at the top. Any change that would meaningfully reduce your privacy will be called out in the app before it takes effect.
