Privacy Policy
TL;DR
AI Audio Cleaner runs entirely on your iPhone. We do not collect, store, or transmit your audio files or any personal data to our servers. We have no servers, no accounts, no analytics, and no third-party tracking SDKs.
1. Who we are
This app is published by Crocolab, an independent developer operating as a sole individual based in Israel ("we", "us", "our"). If you have questions about this policy, contact us at crocolab.support@gmail.com.
2. What this app does
AI Audio Cleaner is an offline tool that removes background noise from audio files using on-device AI (DeepFilterNet via Core ML). You select an audio file from the Files app, the app processes it locally on your iPhone, and you receive a cleaned file you can save or share.
3. Data we do NOT collect
We do not collect, see, store, transmit, or share any of the following:
- The audio files you import, process, or export
- Any content of those files
- Any analytics about your use of the app (number of sessions, features used, time spent, crashes, etc.)
- Your name, email address, phone number, location, contacts, photos, or any other personal information
- Your IP address, device identifiers (IDFA, IDFV), or advertising identifiers
- Cookies (we have no web component)
The app does not contain any third-party analytics SDKs (Firebase, Mixpanel, Amplitude, AppsFlyer, etc.) or advertising SDKs.
4. Data the app stores locally on your device
Everything below is stored only on your iPhone and never leaves your device. It is removed when you delete the app.
| Item | Where | Purpose |
|---|---|---|
| Cleaned audio files | App's local Documents folder | History feature (last 10 cleanups) |
| Original imported audio files | App's local Documents folder | Before/After comparison in History |
| App preferences (color scheme, denoise strength, app icon, onboarding flag) | UserDefaults | Remember your settings |
| Usage counter (number of files cleaned this calendar month) | UserDefaults | Enforce the 5-files-per-month free tier limit |
| Review prompt timestamps | UserDefaults | Avoid showing the rating prompt too often |
| Purchase status (Pro unlock) | StoreKit (Apple's system) | Determine whether you have the Pro upgrade |
You can erase all of this at any time by deleting the app or, for the locally-stored files, by clearing entries from the History screen.
5. Audio processing
All audio processing is performed locally on your iPhone using Apple's CoreML framework and the DeepFilterNet model bundled with the app. Your audio never leaves your device. No internet connection is required for processing.
We do not have, and do not maintain, any server infrastructure that could receive your audio.
6. Third-party services we use
The app uses a small number of Apple-provided system frameworks. These do not transmit your audio content. The full list:
- StoreKit (Apple). Handles the optional one-time Pro purchase. Apple may collect transaction data as described in their privacy policy. We receive only a yes/no signal about whether the purchase has been completed, with no personally identifying details.
- SKStoreReviewController (Apple). Used to display the system's native "Rate this app" dialog. We receive no information about whether you submitted a rating or what rating you gave.
- StoreKit AppStore.sync() (Apple). Used when you tap "Restore Purchase". Restores any previous purchase from your Apple ID. Same privacy applies as for StoreKit above.
- Files / Document Picker (Apple). Used to import audio files. We receive only the file you select; we do not browse, list, or access any other file on your device.
- Share Sheet (Apple). Used to share the cleaned file. We do not see or store where you send it.
The DeepFilterNet model itself is bundled inside the app at install time. It does not make any network requests.
7. Required-reason API declarations
In accordance with Apple's App Store policy, we declare the following required-reason APIs in our Privacy Manifest (PrivacyInfo.xcprivacy):
- UserDefaults — reason
CA92.1("Access info from same app on same device"). Used to store your preferences and free-tier usage counter, as described in Section 4.
No other declared categories apply because we do not access file timestamps, disk space, system boot time, or any other restricted APIs.
8. Children's privacy
This app is rated 4+ on the App Store. We do not knowingly collect any data from children of any age. If you believe a child has somehow provided us with personal information, please contact us — but note that we do not have any mechanism to receive such data, since the app does not transmit user data of any kind.
9. Data security
Because we do not collect or transmit your data, there is nothing on our side that can be breached. All data remains in your iPhone's app sandbox, which is protected by iOS-level encryption and access controls.
10. International transfers
We perform no data transfers because we do not collect data. The DeepFilterNet model and the app code are downloaded from the App Store and installed entirely on your device.
11. Your rights
Because we do not collect or store your personal data, there is no personal data we can grant access to, correct, export, or delete on your request. You retain full control over the audio files and app data on your device through the Files app and through deleting the app.
If your jurisdiction (e.g. EU, UK, California) provides additional consumer rights, those rights still apply by default — they simply do not have a target, because no data exists on our side.
12. Changes to this policy
If we make any material change to this policy, we will update the Last updated date at the top and post the new version at the URL where you found this document. Continued use of the app after the change constitutes acceptance of the new policy.
