MellVox AI — Privacy Policy

App: MellVox AI Platforms: iOS, iPadOS, macOS Last Updated: September 10, 2026 Version: 1.1.0

1. Summary

MellVox AI is a fully on-device voice recording and transcription app.

  • There is no membership or user account.
  • No audio or transcript data is ever sent to, collected by, or processed on any server. We do not operate a server.
  • The only network traffic is purchase-related (product prices, purchases, restore, and entitlement checks), and it goes exclusively to Apple via the system StoreKit framework.
  • All audio processing, transcription, and storage take place on the user’s own device.
  • Recording and transcription work without an internet connection (model files are included in the app package). Product prices, purchases, restore, and grandfather checks require an internet connection.

This policy transparently explains the app's privacy approach.

2. What Data Is Collected?

No personal data is collected.

The app does not collect:

  • Name, surname, email, or phone number
  • Location, IP address, or device identifiers
  • Usage statistics or analytics data
  • Crash reports or telemetry
  • Any third-party services (Firebase, Analytics, etc.)

Data stored locally (never leaves the device):

  • Your voice recordings (WAV files)
  • Transcript text and timestamps
  • Recording titles, durations, and favorite markers
  • In-app simple counters (e.g., successful transcription count — used only to trigger the App Store review prompt; never sent externally)
  • Monthly transcription quota counters and Premium / grandfather status (stored only to manage the free tier and unlocked features; never sent externally)

3. Where and How Is Data Stored?

  • Audio files: Stored as .wav files in your device's Documents/Recordings folder (16 kHz mono PCM).
  • Transcripts and metadata: Stored in a local SwiftData database (Application Support/default.store).
  • User preferences: Standard UserDefaults (review prompt status, monthly quota counters, and locally cached Premium / grandfather status).

This data:

  • Exists only on your device.
  • Is permanently deleted when you uninstall the app or use "Delete App" / "Remove Data from My Device."

4. System Permissions Used

The app requests only the following permissions:

Permission Purpose Required?
Microphone (NSMicrophoneUsageDescription) To record audio Yes (for recording)
Background audio (UIBackgroundModes: audio) To continue recording when the app is sent to the background Yes (iOS)
Read/write user-selected files To import audio files and export transcripts Yes (only when the user selects a file)

The app never:

  • Accesses photos, camera, location, contacts, calendar, or health data.
  • Requests push notifications.
  • Includes advertising or tracking SDKs.

5. Transcription (Speech → Text)

  • Transcription is performed on-device using the Whisper (whisper.cpp + Core ML) model included in the app package.
  • Audio data is never sent over the network.
  • Model files are bundled inside the app.
  • No external APIs are used (OpenAI, Google, Apple Speech Recognition, etc.).

6. Export

When the user voluntarily exports a transcript:

  • A file is created in TXT, Markdown, SRT, or VTT format.
  • The file is sent directly to the system share sheet or file saver.
  • The app does not upload or copy this file to any server outside its control.

Exported content is the user's own responsibility.

7. Import

When the user selects their own audio files (MP3, M4A, WAV, etc.):

  • The file is read locally and converted to 16 kHz mono WAV format.
  • The original file is not modified.
  • Temporary copies are cleaned up after processing completes.

8. Payments and Purchases

MellVox AI is free to download. Unlimited transcription is available through optional In-App Purchases:

  • Auto-renewable subscriptions (monthly and yearly)
  • A one-time lifetime purchase

Purchases are processed exclusively by Apple through the App Store / Mac App Store (StoreKit). As the developer, we do not collect credit card details, billing addresses, or any payment information. We do not operate a purchase server, and we do not receive Apple receipts or Apple ID data.

Apple’s privacy policy applies to the purchase process. You can manage or cancel subscriptions in your Apple ID settings.

Users who previously paid to download MellVox AI keep unlimited transcription on that Apple ID (lifetime access). Audio and transcripts are never uploaded as part of a purchase.

9. Third-Party Software

The app uses the following open-source component:

  • whisper.cpp (MIT License) — developed by Georgi Gerganov and contributors. Runs entirely on-device; includes no network connectivity or data collection.

The license text is displayed in the in-app "License" screen.

10. Children's Privacy

The app is not designed for children under 13. We do not knowingly collect personal data from anyone under 13. If you become aware of such a situation, please contact us.

11. Data Security

  • All data is stored within the device's sandbox environment.
  • The app benefits from Apple's App Sandbox and data protection mechanisms.
  • Device security (Face ID / Touch ID / Passcode) is the user's own responsibility.

12. Changes

This Privacy Policy may be updated from time to time. When significant changes occur:

  • They will be noted in the app's release notes.
  • The "Last Updated" date of this policy will be revised.
  • Users are encouraged to review the policy periodically.
