The short version
Ohm Studio collects no data. None.
No analytics. No telemetry. No account. No personal data. No usage metrics. No error beacons. No advertising IDs. No fingerprinting. No crash reports. No data of any kind is collected, stored, transmitted, or shared by Ohm Studio about you, your device, or your activity.
Everything Ohm Studio does (text-to-music generation, LoRA / LoKR adapter training, stem separation, audio analysis, lyrics generation) runs entirely on your Mac, on-device, using Apple's MLX framework and locally-stored open-weights models. There is no cloud component. There is no server. There is no Ohm Studio account.
What we don't have, and therefore never see
Because Ohm Studio has no server-side component, the following do not exist anywhere in our infrastructure (and our infrastructure consists of: nothing):
- Your name, email, phone, or address.
- Your IP address, device identifier, MAC address, or any other hardware fingerprint.
- Your prompts, lyrics, generated audio, reference audio, training datasets, trained LoRA adapters, or any other content you produce in the app.
- Microphone recordings.
- The contents of your Documents, Downloads, Desktop, or any other folder.
- Session timing, feature usage, button clicks, or any other behavioural data.
- Crash reports. Ohm Studio does not implement a crash-reporting SDK.
We never see any of this because none of it is ever sent. The app does not phone home, ever.
Outbound traffic you initiate
Three classes of outbound network traffic can originate from your Mac while Ohm Studio is running. None of them go to Ohm Studio. All of them are user-initiated:
- Model weight downloads. The first time you choose to install a model, the app downloads the relevant ACE-Step or stem-separation checkpoint from public open-weights repositories, primarily ModelScope with Hugging Face as a fallback. The download is anonymous by default; no token, account, or registration is required. If you optionally paste a Hugging Face token into Settings to access a gated model, the token is stored only in your local preferences file on your Mac and is sent only to
huggingface.coto authenticate the download. Ohm Studio never sees the token. - Mac App Store updates.When Apple ships an Ohm Studio update, the Mac App Store delivers it. This traffic is between your Mac and Apple's servers, governed by Apple's privacy policy. Ohm Studio is not involved.
- Links you click. If you click an external link inside the app (for example, opening this privacy policy), your default browser handles the request. Ohm Studio is not involved.
On-device data you create
The audio you generate, the datasets you assemble, the adapters you train, the lyrics you draft, and your local preferences live on your disk under ~/Library/Containers/com.ohmstudio.app/Data/Library/Application Support/Ohm/ (plus any folders you explicitly choose). They are yours. We do not have access to them. Deleting Ohm Studio removes the app; your work remains under its container until you delete it manually.
Children's privacy
Ohm Studio is rated 4+ on the Mac App Store. 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.
Third-party services
Ohm Studio uses these open-source components and public services. None of them receive any data about you from Ohm Studio:
- ACE-Step 1.5 (open-weights music model, MIT): runs locally.
- MLX(Apple's array framework): runs locally.
- librosa (audio analysis): runs locally.
- Ultimate Vocal Remover models (stem separation): runs locally.
- Hugging Face Hub / ModelScope: contacted only when you choose to download a model checkpoint.
Changes
If we ever materially change how Ohm Studio handles data (for example, if a future version of the app begins to collect anything at all) 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 effective date at the top of this document reflects the current policy.
The current policy is: nothing is collected.
