Privacy Policy

Last updated: March 21, 2026

Overview

VoiceNPC is built around a simple principle: your voice data never leaves your device. All voice cloning, speech generation, and audio processing happens entirely on your device using on-device machine learning. No server, no cloud, no exceptions.

What We Don't Collect

• Voice recordings or audio files
• Generated speech content
• Text you type for generation
• Voice fingerprints or embeddings

We have zero access to the content you create with VoiceNPC. The AI model runs locally on Apple Silicon, and all data stays in your app's private sandbox.

What We Do Collect

To operate the app and improve your experience, we may collect minimal, non-identifying data:

• Crash reports — anonymous crash logs via Apple's built-in crash reporting to help us fix bugs.
• Purchase records — managed by Apple through the App Store. We receive subscription status but not payment details.
• Ad interactions & advertising data — if you choose to watch rewarded ads for energy, the ad network (Google AdMob) may collect standard ad interaction data. This only applies to free-tier users who opt in to watching ads. See "Advertising & Your Choices" below for details.

Advertising & Your Choices

Free-tier users may watch optional rewarded ads to earn energy. These ads are served by Google AdMob. To help show relevant ads, the app may request access to your device's advertising identifier (IDFA) via Apple's App Tracking Transparency framework.

You are always asked for permission first. If you decline tracking, you will still see ads — they simply won't be personalized. Your choice does not affect any other app functionality.

If you are located in the European Economic Area (EEA) or the United Kingdom, a consent dialog will appear before any ad data is collected, in compliance with the General Data Protection Regulation (GDPR). You may consent to, decline, or withdraw consent for personalized advertising at any time. To change your choice later, delete and reinstall the app, or contact us at the email below.

Data that may be collected by the ad network when you watch an ad includes: device identifiers, IP address, ad interaction data (views, taps), and general device information. This data is processed by Google under Google's Privacy Policy. We do not receive or store any of this data ourselves.

On-Device Processing

VoiceNPC uses the Qwen3-TTS neural network model, which runs entirely on your device via Apple's MLX framework. The model is bundled with the app — no download or server connection is needed for voice cloning or speech generation. Your voice data is processed in-memory and stored only in local files within the app sandbox.

Data Storage

All app data is stored locally on your device:

• Voice recordings and clones are saved in the app's Documents directory
• Generated audio files are saved locally
• App preferences are stored in UserDefaults
• Generation history is stored in a local SwiftData database

Uninstalling VoiceNPC permanently deletes all associated data from your device.

Third-Party Services

• Apple App Store — for app distribution and in-app purchases
• Google AdMob — for optional rewarded ads (free tier only). May serve personalized or non-personalized ads depending on your consent choices. Subject to Google's Privacy Policy.
• Google User Messaging Platform (UMP) — used to present consent dialogs for advertising preferences and GDPR compliance.

Your Rights

Since VoiceNPC processes nearly all data on-device, your data is already under your control — deleting the app removes everything. For advertising data collected by Google when you watch ads, you can manage or delete it directly at Google's Data & Privacy page. You can also reset your advertising identifier or disable personalized ads in your device's Settings > Privacy > Tracking at any time.

Children's Privacy

VoiceNPC is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
