Privacy and Permissions
In development
The YucDu macOS app is still in development and is not yet available on the Mac App Store. This guide is based on the current development build; features and screens may change before release.
What YucDu doesn't do
- No account and no sign-in required.
- The macOS version has no ads. It doesn't load ads or ask for permission to track you.
- No third-party analytics or advertising tools.
Permissions the app uses
| Permission | Purpose |
|---|---|
| Notifications | New-article notifications (being prepared; not being sent yet). You can decline, and change it any time in macOS System Settings > Notifications. |
| Network | Loading articles, images, service status and legal documents. |
| iCloud | Syncing your favorites across your devices. |
The app does not ask for access to your location, camera, microphone or contacts, and it doesn't ask for access to your files.
Where your data is stored
| Data | Where it's stored |
|---|---|
| Favorites | Your own private iCloud database, synced across devices signed in to the same Apple Account; we can't read its contents. When iCloud isn't available, they're saved on this Mac only. |
| Reading history and progress | On this Mac only (up to 20 articles in your history). |
| Search history | On this Mac only (up to 10 entries). |
| Offline articles | On this Mac only; they expire after 14 days. |
| Appearance and notification sound settings, window state | On this Mac only. |
Connections the app makes
- Articles, categories, search and other content are loaded over encrypted connections (HTTPS) from yucdu.com-related services; service status and legal documents come from Yucts services.
- When you open an article, the app sends one request to yucdu.com to count the article's views. Just as when you visit the site in a browser, the website receives your IP address.
- If you allow notifications, the app sends this Mac's push token and your notification sound setting to our notification service (api.yucdu.com). The token isn't linked to your identity and isn't used for tracking; it expires automatically if it isn't updated for 180 days.
- The share pages of LINE, X, Threads or Facebook open only when you choose to share.
Deleting your data
- Favorites — remove them one at a time; the synced copy in iCloud is deleted too. You can also manage your Apple Account's iCloud storage in macOS System Settings.
- Reading history and progress — click "Clear History" in "History".
- Search history — in "Recent Searches" under "Search", delete entries one at a time or click "Clear All".
- Offline articles — click "Clear All" in "Offline Reading".
- Removing the app — when you delete the app, the app data stored on this Mac is removed as well.
