SlyMask 棒球（以下简称“本应用”）由刘肖龙（个人开发者）开发与维护。本隐私政策适用于本应用的 iPhone 版本，以及与其配套的 Apple Watch 版本。
我们重视你的隐私与数据安全。SlyMask 棒球的大多数核心功能采用设备本地处理方式完成。除 Apple 提供的系统服务外，我们不会建立用于存储你的训练视频、分析结果、健康数据或比赛记录的开发者自有服务器。
本政策用于说明：当你使用本应用时，我们会处理哪些信息、如何处理这些信息，以及你可以如何管理自己的数据与权限。
当你使用 AR 测距、训练视频录制等功能时，本应用会请求相机权限。
当你选择本地视频、照片或文件进行动作分析时，本应用会请求相册或文件访问权限。
为了提供功能，本应用会在你的设备上处理你主动创建、记录或导入的内容，例如：
这些内容主要用于实现本应用的训练、记录、回顾、统计、成就与展示功能。
当你在 Apple Watch 上使用训练相关功能并授权 HealthKit 后，本应用可能读取和写入以下健康/运动数据：
相关数据由 Apple Health / HealthKit 管理。我们不会将这些健康数据上传至开发者自建服务器。
当你在 Apple Watch 上使用训练功能时，本应用可能处理设备运动传感器数据，例如：
用途主要包括：
这些数据主要在设备本地处理，不用于广告跟踪。
当你购买、恢复购买或使用 SlyMask Pro 时，购买流程由 Apple 的 StoreKit 处理。
本应用可能读取与你的购买结果和权益状态相关的必要信息，例如：
我们无法访问你的 Apple ID 密码、银行卡号、支付密码或其他完整支付信息。
如果你登录或启用 Apple Game Center，本应用可能会使用 Apple 提供的能力处理：
这些能力由 Apple 提供并管理，不属于开发者自建账号体系。
为了让 iPhone 与 Apple Watch 之间的训练体验保持一致，本应用可能通过 Apple 提供的系统机制在你的设备之间同步必要信息，例如：
如果你的设备登录了同一 Apple 账号并可使用 iCloud，部分轻量状态数据（例如成就解锁状态等）可能通过 Apple 提供的 iCloud Key-Value Store 在你的设备之间同步。
除非你主动通过电子邮件联系我们，否则我们通常不会直接收集以下信息：
本应用不要求你注册账号才可使用主要功能。
我们处理上述信息，主要用于以下目的：
本应用不会将你的数据用于：
本应用的大部分数据默认保存在你的设备本地，包括但不限于：
你导入的视频、照片以及由此生成的大部分分析结果，主要在设备本地完成处理。
我们不会将这些原始媒体内容上传到开发者自建服务器。
如果你授权本应用访问 HealthKit：
订阅、续费、恢复购买等流程由 Apple 处理。
在你的设备满足 Apple 系统条件时，部分轻量状态数据（如成就解锁状态）可能通过 iCloud Key-Value Store 在同一 Apple 账号下的设备之间同步。
该同步能力由 Apple 提供和管理，并非开发者自建云服务。
为了支持 Apple Watch、复杂功能状态同步或相关展示能力，部分轻量训练摘要和状态信息可能存放于 Apple 提供的 App Group 共享容器中，仅用于你自己设备上的功能展示与协作。
当你使用本应用的导出或系统分享功能时：
本应用当前主要使用 Apple 提供的系统框架和服务，例如：
截至当前版本，我们未集成第三方广告 SDK、第三方用户画像 SDK 或第三方追踪 SDK 用于广告跟踪或出售用户数据。
我们不会向第三方出售、出租或交易你的个人信息。
仅在以下有限情形下，相关信息可能被披露或按系统机制处理：
当你主动使用系统分享功能导出图片、视频、卡片或其他内容时，分享对象和范围由你自行决定。
如适用法律、法院或监管机构依法要求披露，或为履行法定义务所必需时，我们可能依法配合。
在为保护你、其他用户、开发者或公众的人身安全、财产安全及合法权益所必要时，可能依法进行必要处理。
当你使用 Apple Health、StoreKit、iCloud、WatchConnectivity、Game Center 等 Apple 系统服务时，相关数据会按 Apple 的平台机制和隐私规则处理。
你可以随时在系统中管理或撤回相关权限，例如：
撤回授权后，相关功能可能无法继续使用或会受到限制。
你可以通过以下方式删除数据：
本应用可能提供清理本地内容的功能。请注意：
如果你不希望 Apple 的 iCloud 机制在你的设备之间同步部分轻量状态，可以通过你的 Apple 账号 / iCloud 设置管理相关同步能力。
你可以在 Apple 账户的订阅管理中随时取消或管理订阅。
如果你对本隐私政策或数据处理方式有疑问、建议或投诉，可以通过本文末尾的联系方式联系我们。

SlyMask Baseball (the “App”) is developed and maintained by Xiaolong Liu, an independent developer. This Privacy Policy applies to the iPhone version of the App and its companion Apple Watch version.
We value your privacy and data security. Most core features of SlyMask Baseball are completed through on-device local processing. Except for Apple-provided system services, we do not operate developer-owned servers to store your training videos, analysis results, health data, or game records.
This Policy explains what information we process when you use the App, how we process it, and what rights and choices you have.
When you use AR distance measurement, training video recording, and related features, the App may request camera access.
When you select local videos, photos, or files for motion analysis, the App may request access to your photo library or files.
To provide the App’s features, we process content that you actively create, record, or import, including for example:
This content is used to provide training, recording, review, statistics, achievements, and display features within the App.
If you authorize HealthKit when using training-related features on Apple Watch, the App may read and write health / fitness data such as:
This data is managed by Apple Health / HealthKit. We do not upload health data to developer-owned servers.
When you use Apple Watch training features, the App may process motion sensor data such as:
This data is primarily used for:
It is mainly processed locally on the device and is not used for advertising tracking.
When you purchase, restore, or use SlyMask Pro, purchases are handled by Apple’s StoreKit.
The App may read necessary information related to purchase results and entitlement status, such as:
We cannot access your Apple ID password, payment password, bank card number, or full payment credentials.
If you sign in to or use Apple Game Center, the App may use Apple-provided capabilities related to:
These functions are provided and managed by Apple and do not create a separate developer-owned account system.
To keep the training experience consistent between iPhone and Apple Watch, the App may synchronize necessary information between your devices through Apple system mechanisms, such as:
If your devices are signed into the same Apple account and iCloud is available, some lightweight state data (such as achievement unlock state) may also sync through Apple’s iCloud Key-Value Store.
Unless you voluntarily contact us by email, we generally do not directly collect:
The App does not require account registration to use its main features.
We process the above information mainly to:
We do not use your data for:
Most App data is stored locally on your device, including but not limited to:
Imported videos and photos, and most analysis results generated from them, are processed locally on your device.
We do not upload raw media content to developer-owned servers.
If you authorize HealthKit:
Subscriptions, renewals, and purchase restoration are handled by Apple.
When Apple system conditions are met, some lightweight state data (such as achievement unlock state) may sync across devices under the same Apple account through iCloud Key-Value Store.
This sync capability is provided and managed by Apple, not by a developer-owned cloud service.
To support Apple Watch integration, advanced sync, or related display functions, certain lightweight training summaries and states may be stored in Apple’s App Group shared container for use across your own devices.
When you use export or system sharing features:
The App currently mainly uses Apple-provided frameworks and services, such as:
As of the current version, we do not integrate third-party advertising SDKs, profiling SDKs, or tracking SDKs for ad tracking or data selling.
We do not sell, rent, or trade your personal information to third parties.
Information may only be disclosed or handled under system mechanisms in limited situations such as:
When you voluntarily use system sharing features to export images, videos, cards, or other content, you control the recipients and scope.
We may comply when disclosure is required by applicable law, court order, regulator request, or other legal obligation.
We may process information where reasonably necessary to protect your rights, the rights of other users, the developer, or public safety.
When you use Apple Health, StoreKit, iCloud, WatchConnectivity, Game Center, or other Apple services, related data may be processed according to Apple’s own platform rules and privacy policies.
You can manage or revoke permissions at any time through system settings, such as:
If you revoke permission, related features may stop working or become limited.
You may delete data in the following ways:
The App may provide features to clear local content. Please note:
If you do not want Apple’s iCloud mechanism to synchronize certain lightweight state across your devices, you can manage related sync settings in your Apple account / iCloud settings.
You may manage or cancel subscriptions through your Apple account subscription settings at any time.
If you have questions, suggestions, or complaints regarding this Privacy Policy or our data handling practices, you may contact us using the contact information below.
The App is designed for baseball / softball training, recording, and learning scenarios and may be used by people of different age groups.
We do not knowingly collect unnecessary personal information from children under 13.
If you are a guardian and believe a minor has provided unnecessary personal information while using the App, please contact us and we will assist after verification.
We may update this Privacy Policy from time to time based on product changes, legal requirements, or Apple platform requirements.
Updated versions may be presented through one or more of the following methods:
By continuing to use the App after an update takes effect, you acknowledge and accept the updated Privacy Policy.
