Privacy Policy

Effective April 29, 2026 · Developer Working Model LLC

# 1.0Overview

Audiary is a text-to-speech app for iOS. Your privacy is important to us. This policy explains what data Audiary collects, how it is used, and your choices.

# 2.0Data Collection

Audiary does not collect, transmit, or store any personal data on external servers. All user content (text, audiaries, settings, and listening history) is stored locally on your device.

2.1What stays on your device

Text you add or import into Audiary
Playback settings (voice selection, speed, theme, word tracking preference)
Listening statistics (total time listened, completed audiaries)
Custom pronunciation entries
Purchase status

2.2Apple services

Audiary uses the following Apple-provided services:

In-App Purchases (StoreKit): Purchase transactions are processed entirely by Apple. Audiary receives only a confirmation of purchase status. We do not have access to your payment information.
Crash Reports (App Store Connect): If you have opted in to share analytics with app developers through your iOS Settings, Apple may share anonymized, aggregated crash data with us. This data contains no personally identifiable information. You can control this in Settings > Privacy & Security > Analytics & Improvements > Share with App Developers.
On-Demand Resources (Apple CDN): The neural voice model (~325 MB) is delivered through Apple's On-Demand Resources system if you choose the neural voice tier. This download is handled by iOS and contains only the model files needed for on-device speech synthesis. No personal data or text is sent during this download.
Apple system voices (AVSpeechSynthesizer): When you select an Enhanced or Default voice, speech is synthesized on-device using Apple's built-in speech engine. No text is sent to any server.

2.3Speech synthesis

All speech synthesis happens entirely on your device:

Neural voices are generated on-device by a locally-stored AI model (Kokoro 82M), executed through Apple's Core ML framework. Your text is never sent to any server for inference.
Enhanced and Default voices use Apple's built-in AVSpeechSynthesizer, which also runs on-device.

In all cases, the text you read in Audiary stays on your device.

2.4Data we do NOT collect

No analytics or usage tracking
No advertising identifiers
No location data
No contacts or calendar access
No microphone or camera access
No network requests to third-party services
No accounts or sign-ins

# 3.0Data Sharing

Audiary does not share any data with third parties. We have no servers, no databases, and no data pipelines.

# 4.0Data Storage and Security

All data is stored in your device's local storage using Apple's SwiftData framework. If you use the Share Extension to import content, that content is stored in a shared app container on your device — it is never transmitted externally.

# 5.0Data Deletion

You can delete any audiary at any time from within the app. Uninstalling Audiary removes all associated data from your device.

# 6.0Children's Privacy

Audiary does not knowingly collect any data from children under 13. Since the app collects no personal data from any user, there is no children's data to protect.

# 7.0Changes to This Policy

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

# 8.0Contact
