App Overview
私语-量子加密输入法
你是否有过这样的体验，刚和朋友聊完某个东西，转眼就在其他软件上看到了推送广告，甚至是接到不厌其烦的电话骚扰，这种感觉就像被人凭空窥探了生活。当大数据越来越大，AI越来越智能，我们的安全感却越来越模糊，你可能已经低估了输入法，才是所有软件里那个最有可能的知情者。它不是唯一的问题，但它可能是最早、最深的那条裂缝……

Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Screen plan
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Differentiate and validate
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Assumption to check: Potential lack of encryption transparency
Validate with people who use this workflow before building.
Hypothesis 3
Design an onboarding process with tutorials to guide new users.
Assumption to check: User interface may be confusing for non-tech users
Validate with people who use this workflow before building.
Hypothesis 4
Implement user accounts and cloud sync for better data management.
Assumption to check: No account or sync features
Validate with people who use this workflow before building.

App Store description
你是否有过这样的体验，刚和朋友聊完某个东西，转眼就在其他软件上看到了推送广告，甚至是接到不厌其烦的电话骚扰，这种感觉就像被人凭空窥探了生活。当大数据越来越大，AI越来越智能，我们的安全感却越来越模糊，你可能已经低估了输入法，才是所有软件里那个最有可能的知情者。它不是唯一的问题，但它可能是最早、最深的那条裂缝…… 【首款量子加密输入法】 基于先进的「类QKD量子密钥分发」技术、「PQC抗量子密钥协商技术」和「金融级商用密码算法SM234」，您可以安全地在传统互联网及任意聊天软件中传输加密消息。 【无联网 无广告 无AI】 这是一款三无产品，让输入法回归简单纯净。坦白说，我们很小、很穷、买不起服务器，所以它只能离线运行。好消息是，没有广告，没有AI，没有数据上传，你的秘密永远留在你手里。 【多种加密模式】 「标准加密」模式：快速完成消息加密，让你的每一句话，不会被拿去训练模型，不会被拿去优化推荐，不会被拿去用户画像。 「好友密聊」模式：使用安全的离线二维码添加好友，实现一对一密聊，我的秘密，只对你可见。 「群组密聊」模式：使用安全的离线二维码添加群组，实现群组内密聊，群里的悄悄话，只留在群里。 【加密还有新玩法】 消息加密：你的长篇大论，终于不用再说给自己听。 图片加密：是谁的私密图片，只想给一个人看？ 文件加密：那些不能见光的合同/图纸/笔记，总算能放心传了。 【一次性购买，无订阅，无内购】 告别订阅，一次拥有！ 安全的输入，不必续租！ 用户协议及隐私政策： https://agreement-and-privacy.pages.dev/SiyuSIME-Agreement

Build scope
Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Define the first version
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Set boundaries
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Check the hard parts
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
