Your recording never leaves your device.
ARP the app cleans and transcribes recordings of speech on your iPhone or iPad. Your audio is processed on the device and never uploaded. There is no ARP server and no account. The privacy manifest Apple reviews (PrivacyInfo.xcprivacy) declares NSPrivacyCollectedDataTypes: [] — the empty list — and NSPrivacyTracking: false.
This website (arpaudio.app) is separate: it uses PostHog for website analytics. That does not run inside the app.
Summary
- Recordings are cleaned and transcribed on your device. They are never uploaded.
- The app has no analytics, no telemetry and no third-party SDKs.
- The one network request the app itself triggers is Apple's on-device speech model, downloaded once the first time you transcribe. No audio is sent with it.
- No account. No login. We never receive your name or email through the app.
- Delete the app and everything it stored goes with it.
Website analytics
arpaudio.app loads the PostHog JavaScript SDK to record standard web analytics (for example page views, referrers, demo playback and clicks to the App Store). Events go to PostHog's US cloud (us.i.posthog.com). We do not use it to identify you by name or email, and PostHog is not in the app. PostHog's own privacy terms apply to the data it processes for us. You can block third-party scripts in your browser; the site still works.
1. What we collect
Nothing that leaves your device.
ARP does not collect your name, email, contacts, location, photos, microphone input, camera, calendar, health data, browsing history, advertising identifier, or anything else covered by Apple's privacy labels. ARP does not record audio and does not ask for the microphone.
The manifest lists two kinds of "required-reason" API, both local: file timestamps (reasons 3B52.1 and 0A2A.1), to manage the files you import and export, and UserDefaults (CA92.1), to remember your settings. Neither sends anything anywhere.
2. How your audio is handled
You add a recording from the Files app (including iCloud Drive). ARP copies it into its own storage on your device. Cleaning — measuring the background level, RNNoise noise reduction, tone shaping and a loudness match — runs on your device. So does the "Removed" track, which is the difference between the original and the cleaned version.
Transcription uses Apple's on-device speech recognition (SpeechAnalyzer). Recognition happens on your device; the audio is not sent to Apple or to us.
Exports (M4A, and 24-bit WAV and AIFF with Premium) and transcript files (TXT, SRT) are written only where you send them, through the system share sheet.
3. The one network request
The first time you transcribe, iOS downloads Apple's speech model for your language, if it isn't already on the device. That download is between your device and Apple. It carries no audio and nothing from your recordings. After that, transcription works offline.
Apple's own frameworks also contact the App Store on your behalf for purchases: loading the Premium price, buying, and restoring. ARP has no server of its own.
4. What is stored on your device
Inside ARP's private storage on your device: the recordings you import, their cleaned versions, the "Removed" tracks, the transcripts you create, and a small library file (library.json) with titles, lengths, waveforms and cleaning reports. Settings are kept in UserDefaults: the cleaning intensity, whether AI cleaning is on, list columns and sorting, and display preferences, together with how many free recordings remain and whether Premium is unlocked.
None of this is shared with any other app, synced to iCloud by ARP, or sent anywhere.
5. Notifications
After your first cleaning or import, ARP may ask to send notifications. If you allow it, it tells you when a cleaning finishes while ARP is in the background. These are local notifications created on your device; ARP uses no push service.
6. Payments
10 recordings are free. ARP Premium is a single non-consumable in-app purchase (ARP.ARP.premium) through Apple's App Store: no limit on recordings, plus 24-bit WAV and AIFF export. M4A export is free for everyone.
Apple handles payment. ARP learns what you bought and when, through StoreKit, but not your Apple Account, payment details or address. Refunds are handled by Apple through the App Store.
7. Your rights
Access. Everything ARP stores is in the app; open it to see your recordings, transcripts and settings.
Delete. Remove a recording in the app to delete it and everything made from it, or delete the app to remove all of it. Originals elsewhere in the Files app are untouched.
Children's data. ARP is not directed to children under 13. We do not knowingly collect data from children because we do not collect data from anyone.
8. Changes
If this policy changes materially — a new data flow, a new third-party SDK, a new destination server — we'll update the date at the top of this page and, for substantial changes, say so in the app.
