Nothing. Wenyang has no account system, no sign-in, and no server of its own. It does not send your data anywhere. It contains no third-party analytics, advertising or attribution SDKs.
These are stored in the app's own sandbox on your device. Deleting the app deletes them. Because we hold no copy, they cannot be recovered afterwards and there is no cloud backup. If you want a backup, use the system-wide iCloud device backup.
Wenyang offers one non-consumable in-app purchase that unlocks exporting. The purchase is handled entirely by Apple's App Store. We never see your payment details. Whether you have unlocked the app is verified on your device against your App Store receipt; that check does not involve any server of ours. Apple's own handling of the transaction is covered by Apple's Privacy Policy.
The app works fully offline. The only network traffic it can cause is Apple's own App Store communication when you tap to purchase or to restore a purchase.
When you export an SVG or a citation list, the file is created on your device and handed to the system share sheet. Where it goes from there is your choice; we are not involved and receive nothing.
The app is rated 4+ and is not directed at children specifically. Since it collects no data, it collects no data from children either.
The ornament in this app is drawn from a program, not scanned from anyone's artwork. Its rules are taken from historical Chinese treatises that are in the public domain, and from museum objects published under CC0. Each entry names its source inside the app, and the app can export that list of citations for you. No image from any modern pattern book is used, and no ornament is AI-generated.
