问易
于变易之中，照见本心。
Consult the I Ching. Reflect within.

A local-first companion for the I Ching. Every AI interpretation runs on your iPhone — never through a cloud LLM.
为什么是问易
Why Yi
端上 AI 解卦
On-device interpretation
解卦由设备端模型生成，你的提问与卦象从不离开手机，也不发往任何第三方服务。
Readings are generated by an on-device model. Your questions and hexagrams never leave the phone, and never reach any third-party service.
本地优先
Local-first by design
所有占问、笔记与复盘都存在本机。没有账号也能完整使用，离线亦然。
Every casting, note and review lives on your device. Fully usable with no account, and offline.
端到端加密同步
End-to-end encrypted sync
可选的跨设备同步采用 AES-256-GCM 端到端加密，密钥只存在你的 iCloud 钥匙串里，服务器只见密文。
Optional cross-device sync is end-to-end encrypted with AES-256-GCM. The key lives only in your iCloud Keychain; the server sees nothing but ciphertext.
复盘与回顾
Reflection & review
为过往的占问安排间隔回顾，把一次卜问变成长期的自我对照。
Spaced review of past castings turns a single question into an ongoing dialogue with yourself.
易学知识库
I Ching knowledge base
六十四卦、爻辞与经典注解随手可查，解卦时即时呈现上下文。
All 64 hexagrams, line statements and classical commentary at hand — surfaced in context as you read.
使用 Apple 登录
Sign in with Apple
开启同步只需 Apple 账户，无需密码，我们不收集你的姓名或通讯录。
Turn on sync with just your Apple ID — no passwords. We never collect your name or contacts.
你的占问，只属于你。
Your questions belong to you alone.
问易按「零知识」原则构建：AI 在端上，数据在本地，同步的内容经端到端加密。我们无法读取你的任何记录——这是设计使然，而非承诺。
Yi is built zero-knowledge: AI on the device, data on the phone, synced content end-to-end encrypted. We cannot read any of your records — by design, not by promise.
