一款市场数据查阅与技术分析研究工具。提供自选列表与 K 线图表、每日市场简报、按技术条件筛查、板块与商品／宏观面板。所有数据来自公开的第三方财经数据服务，均为延时数据。
它不是什么：不连接任何券商或交易所账户，不能下单、不能划转资金，不托管任何资金，也不提供个性化投资建议。“分析”页中的市值与盈亏计算，其输入数字全部由您自己手动键入，应用只做算术并显示结果。
相机取景翻译、照片文字翻译、文本翻译与语音翻译，内置 1117 条工程机械与 IT 专业术语对照表。翻译与文字识别在设备上完成。
请先下载语言包：本应用使用 iOS 系统提供的翻译能力，首次使用某个语言对时需要联网下载一次语言包（在应用内“设置”页一键下载）。下载完成后即可离线使用。
面向工程机械行业的职业英语训练：分阶段词卡、例句发音、单元测验、错题本、收藏夹与行业词典。课程内容全部随应用安装，发音由 iOS 系统语音合成在本机实时生成（安装包内不含音频文件），完全离线可用。
三款应用都不需要注册，也没有登录界面。您的数据只保存在自己的设备上。
三款应用都不设服务器、不收集身份信息、无广告、无追踪。各自的具体数据流向请看下方“隐私政策”一节，每一条都写明了。
数据保存在设备本地，删除应用或更换设备后不会自动迁移。这是“不上传任何数据”的必然代价。
长按主屏幕上的应用图标 → 删除 App。本机数据随之全部清除；开发者处本来就没有您的任何数据。
不是。本应用使用的是公开财经服务提供的延时数据，不是交易所实时授权行情，延迟时长由数据提供方决定。请不要把它当作实时报价使用。
说明该数据源当次请求失败（网络问题，或对方接口临时变更／限流）。应用的设计是明确显示取不到，而不是用别的数字顶替。请稍后重试；若长期不恢复，请发邮件告诉我们具体标的与页面。
完全来自您自己键入的股数与成本价。应用不连接任何券商，无法读取您的真实账户，也不会核对这些数字。它只是一个在本机运行的计算器。
不能，也不会。本应用没有任何下单能力，也不提供投资建议或推荐。所有内容仅供研究参考，任何投资决策及其后果由您自行承担。
翻译能力由 iOS 系统提供，语言包需要由系统下载一次。请到应用内“设置”页选择语言对并点“下载或更新所选语言包”。下载完成后即可断网使用。
请到 iOS「设置 > 隐私与安全性 > 相机」中允许本应用。若您不想给相机权限，仍可使用底部的“文字”与“语音”翻译，以及从相册选图翻译。
请确认已允许“麦克风”和“语音识别”权限。部分语言需要您先在「设置 > 通用 > 键盘 > 听写」中添加对应的听写语言。
不会。翻译全部在设备上完成，应用内没有任何把待翻译内容发往第三方翻译服务的功能。唯一需要联网的只有一次性的语言包下载，而那是由 iOS 系统完成的。
不需要。发音音频随应用一起安装在设备里。
发音统一由 iOS 系统语音合成在本机实时生成，全部词条音色一致，不需要网络。
不会。本应用只有“播放发音”，没有录音功能，也不申请麦克风权限。

A market-data reading and technical-analysis research tool: watchlists and candlestick charts, a daily market brief, technical screening, plus sector, commodity and macro panels. All data comes from public third-party financial data services and is delayed.
What it is not: it connects to no brokerage or exchange account, cannot place orders or move funds, custodies nothing, and offers no personalised investment advice. In the Analysis tab, every input figure is typed in by you; the app only performs arithmetic and displays the result.
Live camera translation, photo text translation, text translation and voice translation, with a built-in glossary of 1,117 construction-machinery and IT terms. Translation and text recognition run on device.
Download a language pack first: the app uses the translation capability provided by iOS, so the first use of a language pair requires a one-time online download of the language pack (one tap in the app's Settings screen). After that it works offline.
Vocational English training for the construction-machinery industry: staged flashcards, sentence pronunciation, unit quizzes, a mistakes notebook, bookmarks and an industry dictionary. All lesson content ships inside the app; pronunciation is generated on the device by the iOS speech synthesiser — fully usable offline.
No. None of the three apps has registration or a login screen. Your data stays on your own device.
None of the apps runs a server, collects identity data, shows ads or does tracking. Each app's exact data flow is spelled out in its privacy policy, linked below.
Data is stored locally, so it does not transfer automatically when you delete the app or switch devices. That is the unavoidable cost of uploading nothing.
Press and hold the app icon on the Home Screen and delete the app. All local data goes with it; the developer never had any of it.
No. The app uses delayed data from public financial services, not exchange-licensed real-time feeds. The delay is determined by each provider. Please do not treat it as a real-time quote.
That request to the data provider failed (network issue, or the provider changed or throttled its endpoint). The app is deliberately designed to state clearly that data could not be retrieved rather than substitute some other number. Please retry later; if it persists, email us with the symbol and screen.
Entirely from the share count and cost basis you type in. The app connects to no broker, cannot read any real account, and does not verify those numbers. It is a calculator running on your phone.
No, and it will not. The app has no order-placement capability and gives no investment advice or recommendations. Everything is for research reference only; all investment decisions and their consequences are yours.
Translation is provided by iOS, and the language pack must be downloaded once by the system. Open Settings inside the app, pick your language pair and tap "Download or update the selected language pack". After that it works offline.
Allow the app in iOS Settings > Privacy & Security > Camera. If you prefer not to grant camera access, the Text and Voice translation modes at the bottom still work, as does translating an image picked from your photo library.
Make sure Microphone and Speech Recognition are allowed. Some languages also require you to add the matching dictation language under Settings > General > Keyboard > Dictation.
No. Translation happens entirely on the device; the app has no feature that sends translatable content to a third-party translation service. The only thing that needs the internet is the one-time language-pack download, and that is performed by iOS.
No. Pronunciation is generated on the device by the iOS speech synthesiser at playback time. The app bundle contains no audio files, so nothing is downloaded and nothing extra is stored.
Yes. Reading speed is set on the “Me” page (slow / normal / fast). The voice is the English voice provided by iOS; which voices are available depends on the voices installed in iOS Settings.
No. The app only plays pronunciation. It has no recording feature and requests no microphone permission.
