Privacy Policy

Last updated: May 30, 2026

ShadowMark is an iOS app for creating, annotating, playing, and recording English shadowing materials. The app is designed around local storage and does not send your learning materials or audio to the developer's servers.

Data We Collect

ShadowMark does not collect personal information, usage data, analytics data, advertising identifiers, location information, contacts, or purchase information. The app does not require account registration.

Learning Materials, Annotations, and Audio

Text you create or import, annotations, selected audio sources, recording data, and settings are stored on your device. ShadowMark does not send this content to external servers.

Microphone Use

The microphone is used only when you record pronunciation practice in recording mode. Recording data is stored on your device and is not sent externally unless you choose to share or export it.

Tracking, Advertising, and Analytics

ShadowMark does not perform tracking, third-party advertising, analytics SDK collection, or external transmission of user behavior.

Exporting and Sharing

If you export images, PDFs, audio files, or similar content, the destination and storage location after export are determined by your own actions.

Changes

If this privacy policy changes, this page will be updated. If there are important changes, they will be announced clearly in the app or on the public page.
