1. Overview
This Privacy Policy explains how OmniAudio, provided by Chang Studio, handles information. OmniAudio does not require an account and does not include advertising or usage analytics.
2. Audio, video, and image files
Files you choose are processed locally on your Mac for the task you select, such as conversion, trimming, compression, merging, ringtone creation, or metadata editing. OmniAudio does not upload your source files, cover images, or exported files to Chang Studio. Normal processing creates a new output file, and you control where it is saved.
3. File and folder access
OmniAudio accesses only files and folders you select or locations allowed by macOS. A security-scoped folder bookmark may be stored locally so the app can continue using your chosen output folder. You can choose a different folder at any time.
4. Information stored on your device
OmniAudio stores app preferences, output-folder access information, purchase entitlement status, and processing history locally. History may include file names, paths, operation names, times, and results. It is not sent to Chang Studio and can be cleared in the app.
5. Purchases
Optional purchases are processed by the Apple App Store through StoreKit. OmniAudio uses StoreKit to retrieve product information, complete and restore purchases, and determine whether Pro is unlocked. Chang Studio does not receive your payment card details or Apple Account password.
6. Data collection and sharing
OmniAudio does not collect personal information, media files, usage analytics, advertising identifiers, or precise location. Chang Studio therefore does not sell or share this information with third parties.
7. Data retention and deletion
Chang Studio does not retain OmniAudio user data on its servers. You can clear processing history in the app. Removing the app and its data removes locally stored preferences and history; exported files remain where you saved them until you delete them.
8. External links
OmniAudio and this website may open App Store, support, or email links. Those services operate under their own privacy policies.
9. Changes to this policy
If OmniAudio’s data practices change, this policy will be updated before the change takes effect. The current effective date appears at the top of this page.
