What the app connects to
The app only connects to servers to show content or carry out something you do:
- Articles, categories, search, authors and archives — loaded from YucDu's service (
api.yucdu.com). When you search, your keywords are sent to this service to get results. - View counts — each time you open an article, the app also sends one request to that article's address on yucdu.com to count the view on the website. As with any web page visit, the yucdu.com server receives connection information such as your IP address.
- Images — loaded from the image addresses in articles (for example YucDu's image server).
- Service Status — fetched from
status.yucts.com. - Legal documents — fetched from
docs.yucts.com. - Push token — if you allow notifications, the app sends this device's push token to YucDu's server. New article notifications are not being sent yet.
- iCloud — favorites sync is handled by Apple's iCloud.
- Sharing and external links — the matching app or website opens only when you tap a share option, Open Video on a YouTube card, or an external link.
All connections use encryption (HTTPS).
Data you can delete yourself
- Favorites — remove them in the Library (with iCloud sync, they're removed from your other devices too).
- Reading history and progress — Library > History > Clear History, or touch and hold a single article to remove it.
- Recent searches — Clear All in the Search tab, or tap the × next to an entry.
- Offline articles — Library > Offline Reading (or Settings > Data > Offline Cache).
- Deleting the app removes the data stored on this device. Favorites stored in iCloud can be deleted from iCloud storage management in iOS Settings.
