隐私政策
决策大师由 Guoyun Liu 提供。决策记录保存在你的设备本地，我们不运营接收这些记录的服务器，也不将回答用于训练 AI 模型。
设备本地的数据
App 使用本地存储保存决策标题、六步回答、进度、日期、报告和历史记录；设置偏好保存在本机。App 没有自建账户、云数据库、广告或第三方分析 SDK，也不跟踪你在其他 App 或网站的活动。
报告和检查提示在本机生成，不向外部 AI 服务发送回答。App 不单独录音、不保存声音，也不请求麦克风权限；若使用系统键盘听写或第三方键盘，其数据处理由对应系统或键盘服务的政策决定。
购买与验证
付款由 Apple 处理。App 通过 StoreKit 获取商品、价格、试用资格及经验证的购买状态，以确认有效使用权限。相关查询可能需要联网；App 不读取你的银行卡或支付密码，不将交易信息发送到开发者服务器。Apple 按其政策处理 App Store 和交易数据。
锁定、导出与分享
若启用 App 锁，身份验证由系统处理，App 不读取或保存面容、指纹等生物识别模板。
复制报告会把内容写入系统剪贴板。导出会在本机生成 JSON、PDF 或图片文件；使用系统分享后，内容将交给你选择的接收方或服务。请自行判断是否包含敏感信息，并注意目标服务的隐私政策。
保留与清除
你可以在 App 内删除记录或清除全部决策数据。这不会自动撤回已复制、导出、备份或分享的独立副本，也不会取消 Apple 订阅。导出临时文件由设备和系统管理；请在相应位置管理需要删除的副本。
本 App 不提供自建云同步。设备系统备份是否包含本地数据，取决于你的系统设置和 Apple 服务；换机或删除 App 前，请自行保存重要记录。
联系与政策更新
如需支持或有隐私问题，请联系 byjackliu@gmail.com。你主动发送的邮件由所用邮件服务处理，我们仅用其内容回应请求。请不要在邮件中发送不必要的敏感资料。
功能或数据处理方式变化时，我们会更新此页面及上方日期。
Privacy policy in English
Decision Master is provided by Guoyun Liu. Decision records stay on your device. We do not operate a server that receives these records and do not use your answers to train AI models.
Local data
The app stores decision titles, six-step answers, progress, dates, reports and history locally. Preferences are stored on the device. There are no app-operated accounts, cloud databases, advertisements or third-party analytics SDKs, and no tracking across other apps or websites.
Reports and rule-based prompts are generated locally without sending answers to external AI services. The app does not record audio or request microphone access. System dictation and third-party keyboards are governed by their respective providers.
Purchases
Apple processes payments. StoreKit provides products, prices, trial eligibility and verified purchase status to determine access. These queries may use the network. The app does not read card details or payment passwords and does not send transactions to a developer-operated server. Apple handles App Store data under its own policies.
App lock, export and sharing
Optional app-lock authentication is performed by the operating system. The app does not read or store biometric templates. Copying a report places its text on the system clipboard. Exports create local JSON, PDF or image files. Sharing sends selected content to the recipient or service you choose; review that service’s privacy practices before sharing sensitive information.
Retention and deletion
You can delete records or clear decision data in the app. This does not remove separate clipboard, exported, backed-up or shared copies and does not cancel an Apple subscription. Exported temporary files are managed on the device; manage independent copies in their respective locations.
The app does not provide its own cloud sync. System backups may include app data depending on your device and Apple service settings. Preserve important records before changing devices or deleting the app.
Contact and changes
For support or privacy questions, contact byjackliu@gmail.com. Emails you send are processed by the relevant email services, and we use their contents to respond to your request. Do not include unnecessary sensitive information. We will update this page and its date when the app’s data practices change.
