Mjudio does not collect your personal data. Everything you do in the app stays on your device, whether that is a Mac, an iPhone or an iPad.
Effective 10 September 2026
The short version. Mjudio has no user accounts, no servers and no tracking. Your audio files, images, lyrics and finished videos never leave your device. We cannot see them, because there is nowhere for them to go.
None. Mjudio does not ask for your name, email address, phone number or any other identifying information. There is no sign-up and no account.
Mjudio is an offline application. The audio you import, the images and video you add, the lyrics you write and the videos you export are all read, processed and written locally on your Mac, iPhone or iPad. None of it is uploaded, transmitted or backed up to us or to anyone else.
Mjudio runs inside the App Sandbox on macOS and inside its own app container on iOS and iPadOS. It can only read files you explicitly choose through a file picker or drag into the app. It has no general access to your disk or your photo library.
Mjudio records a small local diagnostic log — for example, that an export started, its resolution and frame rate, and how long it took. This log is written to a plain file inside the app's own private folder on your device.
This log is never transmitted. It is not sent to us, and it is not shared with any analytics provider. It exists so the app can behave sensibly and so that you can inspect it if you want to. You can turn the recording off entirely in Settings, and deleting the app removes it along with everything else.
The log contains no personal information and no content from your projects — no file names, no file paths, no audio, no images and no lyrics.
This version of Mjudio makes no network requests at all. The app is fully functional with no internet connection.
Purchases are handled by Apple's StoreKit framework rather than by the app — see the next section.
Mjudio offers optional paid upgrades. All payments are processed by Apple through the App Store using StoreKit. We never see, receive or store your payment details, credit card numbers or Apple Account credentials.
Mjudio asks Apple whether the current Apple Account holds a valid Mjudio purchase, and uses the yes-or-no answer to unlock premium features. Apple's handling of that transaction is governed by Apple's Privacy Policy.
We do not sell, rent, trade or share your data, because we do not collect any.
Mjudio contains no third-party advertising, no third-party analytics SDKs and no social media trackers.
Mjudio is suitable for general audiences and does not knowingly collect information from anyone, including children.
If a future version of Mjudio adds a feature that requires transmitting data — for example an online template library — this policy will be updated before that version is released, and the effective date above will change. Continued use of a new version after such an update means you accept the revised policy.
