Privacy Policy

閱讀 (Yuedu Reader) · Last updated: May 26, 2026

Yuedu Reader is a local-first iOS reading app. We do not operate any analytics, tracking, or advertising servers, and we do not collect, sell, or share your personal data. Your books and reading data stay on your device by default; data only leaves your device for services you connect to (iCloud, and the content/speech sources you configure), governed by those services' own privacy policies.

1. What we do not collect

• No third-party analytics, behavioral tracking, or advertising SDKs.
• No developer-operated server logging your activity — the in-app telemetry function is a no-op (sends nothing).
• We never sell or share your data for advertising.

2. Data stored on your device

The following is stored locally on your device (and optionally synced via your own iCloud — see §3):

• Books you import (EPUB / TXT) and their files.
• Reading position, bookmarks, highlights, and annotations.
• Your bookshelf, RSS subscriptions, book sources, and reader preferences.

3. iCloud sync (optional)

If you enable iCloud sync, the app backs up/restores the above data to your own private iCloud account via Apple's CloudKit. This data lives in Apple's iCloud, is accessible only to you, and never passes through or is stored on our servers. It is governed by Apple's Privacy Policy. You can disable sync or delete the iCloud backup at any time.

4. Account & sign-in (optional)

The app offers optional Sign in with Apple and Google Sign-In, used only to identify your account. After signing in, the app stores basic details (your display name, email, and an account identifier) locally on your device. We do not use this to build advertising profiles. Data handled by Apple and Google during sign-in is governed by their respective privacy policies. You can use the app's reading features without signing in.

5. Network sources you configure

The app connects to services for which you provide the URL, sending the necessary requests to those servers:

• RSS feeds and web book sources / online reading: to fetch the content you subscribe to or configure.
• WebDAV: to sync with a WebDAV server you set up.
• Text-to-Speech (TTS): if you configure an HTTP TTS service URL, the app sends the text to be spoken to that service to generate audio. If not configured, nothing is sent.

These are third-party services you choose to connect to; we neither operate them nor receive the data above. Data you send to them is governed by those services' own privacy policies.

6. Children's privacy

This app is not directed to children under 13, and we do not knowingly collect personal data from children.

7. Changes to this policy

If this policy changes, we will update the "Last updated" date at the top of this page. Material changes will be noted in the app or on this project page.
