Licenses

Last updated: 2026-10-17

Shiyu does not include any third-party open-source libraries. Every feature is built on Apple’s system frameworks. This page lists what is used and which terms apply.

1. Apple frameworks

• SwiftUI — interface
• SwiftData — local storage (backed by SQLite)
• CloudKit — iCloud private database sync
• StoreKit 2 — one-time purchase and offer-code redemption
• WidgetKit — Home Screen and Lock Screen widgets
• UserNotifications — local reminders
• Foundation / Swift standard library — core utilities

These ship with iOS and are governed by the Apple Developer Program License Agreement and the iOS SDK Agreement. They are not open-source licensed.

2. Icons and fonts

Icons in the App use Apple’s SF Symbols, subject to Apple’s SF Symbols license. Text uses iOS system fonts (e.g. PingFang, San Francisco). No third-party font files are bundled.

A few small graphics drawn for the App itself (such as the three thin-line tab icons) are our own work and are used only inside the App.

3. Third-party components

None. The project uses no third-party Swift packages, CocoaPods, Carthage, or binary frameworks.

4. About this page

If an open-source component is ever added, its name, version, license text or link, and required attribution will be listed here.
