AudX Privacy Policy

Last updated: 2026-06-20

1. Information we process

(1) Audio and video files

• The audio or video you select in AudX is used only for on-device voice separation, accompaniment extraction, and instrument stem separation.
• AudX decodes audio, runs the separation model, and exports results locally on your device. Your selected media files are not uploaded to our own servers.
• Processed results and temporary files are typically stored in the app sandbox or in the Files folder you choose. You can delete them at any time.

(2) Device permissions

• Photos/Photo Library: used only to read audio or video you explicitly choose from Photos for local separation. AudX does not scan your entire library and does not save results back to Photos.
• Files access (macOS / iOS "Files"): used only to read the audio or video files you choose and to export separated audio into the folders you select.

(3) Basic device information and necessary network requests

• When a free user needs to load ads, determine the ad route, or when the app needs to sync membership / purchase status, the app may make necessary network requests and related services may process basic device information, request logs, approximate region information, ad request / impression / interaction data, diagnostic data, and anti-fraud data.
• These flows do not upload the contents of your selected audio or video files to us for ad delivery.

We do not access files, photos, or media that are unrelated to your use of AudX.

2. Advertising and third-party services

• Free users may see ads in some scenarios, such as a start-task interstitial ad, or may choose to watch a rewarded video ad to receive extra same-day task executions. Subscription and lifetime members do not see these ad flows.
• The iOS version currently integrates Google AdMob and WindSDK (Youlianghui / Sigmob) advertising services. When ads are needed, the app may choose the appropriate service based on storefront region, network region, and ad availability.
• These ad partners may collect or process data required for ad delivery, attribution, frequency control, performance measurement, diagnostics, anti-fraud, and compliance under their own privacy policies, such as device identifiers, IP address, approximate region, and ad impression or click data.
• On supported iOS versions, the app may request App Tracking Transparency permission before loading some ads. You can decide whether to allow this. Denying permission does not affect the core audio and video separation features.
• We do not sell the contents of your selected audio or video files to advertisers, and we do not upload those contents to ad platforms for ad targeting.

2.1 macOS platform note

• The macOS version does not currently display ads and does not integrate the Google AdMob or WindSDK (Youlianghui / Sigmob) ad presentation flows used by the iOS version.
• As a result, the macOS version does not currently trigger the ad requests, rewarded ad flows, or ad-tracking permission prompts used in the iOS version.
• If the macOS version later adds ads, online features, or other capabilities that change how privacy-related data is handled, we will update this privacy policy accordingly.

3. Data storage and retention

• Processed audio and video results and temporary intermediate files are typically stored locally on your device. You can remove them at any time by deleting the files or uninstalling the app.
• We do not operate an audio- or video-processing server that is directly linked to your personal identity. However, Apple StoreKit, advertising SDKs, and necessary network infrastructure may process the minimum data needed for purchase validation, ad delivery, or region routing within their respective services.

4. Children’s privacy

AudX is intended for a general audience and is not designed specifically for children under 13 years of age. If you are a minor, please use this app under the guidance and supervision of a parent or guardian.

5. Your choices and control

Because we do not store your media files or account data on our own servers, you can manage your information by:

• Deleting audio results you no longer need from Files or the output folders you selected;
• Revoking Photos, Files, or other permissions in system settings;
• Uninstalling the app to remove local data stored in the app sandbox;

6. Changes to this policy

We may update this privacy policy from time to time. If there are material changes, we will highlight them in the app update notes and encourage you to review the latest version.
