数学达人是一款面向儿童数学启蒙与思维训练的本地学习应用。我们重视隐私保护。本应用不要求注册账号，不建立用户档案，不通过自有服务器收集或存储您的个人信息。
为了方便家长快速了解，我们先用简明方式说明本应用的隐私情况。
本隐私协议适用于“数学达人”iOS 应用及其在应用内提供的儿童数学启蒙、关卡闯关、数字认知、数量认知、形状认知、比较训练、规律训练、加减练习、思维训练、奖励中心、家长中心等相关功能。
本协议用于说明我们如何看待和处理隐私问题，以及在应用运行过程中可能涉及的本地数据、系统能力和内购状态使用方式。
在正常使用本应用过程中，我们不要求您提供以下信息，也不会主动收集以下信息：
为了实现数学闯关、学习进度保存、奖励展示和家长查看学习情况等功能，应用可能会在您的设备本地保存部分数据，例如：
这些数据主要用于在您的设备上维持应用功能与学习体验，不用于对外共享，也不通过我们的自有服务器进行集中存储。
数学达人主要提供本地数学启蒙和闯关学习功能，通常不需要访问相机、相册或麦克风权限。
本应用不需要获取您的精确定位信息，也不会基于地理位置建立用户画像。
应用内可能提供语音播报、点击音效、答题反馈音效等功能，用于提升儿童交互体验。相关设置保存在设备本地，不会上传到服务器。
本应用的核心学习功能主要可在本地运行。如涉及 App Store 内购、恢复购买、系统验证等能力，可能需要通过苹果系统服务完成。
我们重视儿童用户的使用安全与隐私保护。本应用的设计目标是提供轻量、温和、适合儿童的数学启蒙与思维训练体验。
由于本应用未提供账号体系，也未通过自有服务器收集或留存儿童个人信息，因此我们不会主动建立儿童信息档案。
对于涉及内购、家长中心、恢复购买等功能，我们建议由家长或监护人在了解功能后协助操作。
本应用可能提供 App Store 内购或会员解锁功能。相关购买、支付、订阅、恢复购买等流程由苹果 App Store 系统能力提供支持。
我们不会直接收集您的银行卡号、支付密码等支付敏感信息。相关支付信息由苹果平台按照其规则进行处理。
应用可能会根据苹果系统返回的购买状态，在设备本地记录或判断功能是否已经解锁。
本应用如接入苹果官方提供的系统能力，例如 App Store 内购、恢复购买、系统评分弹窗等，这些能力由设备系统或苹果平台提供支持。
相关数据处理规则可能同时受到苹果平台政策与系统权限机制约束。建议您同时参考苹果官方相关说明。
由于我们未通过自有服务器收集您的个人信息，因此不存在将您的个人信息出售、出租或共享给第三方广告商、数据公司或其他商业机构的情形。
除法律法规另有要求外，我们不会以运营目的披露您的本地学习记录或个人数据。
我们会尽量采用合理方式减少不必要的数据处理，尽可能让应用以本地方式运行。
但也请您理解，任何设备本地数据都可能因设备损坏、系统异常、误删除、卸载应用等原因而发生丢失。建议家长按需自行备份重要设备数据。
如果本应用后续功能发生变化，导致隐私处理方式发生调整，我们可能会对本协议进行更新，并在页面中展示最新版本与更新时间。
如果您对本隐私协议有任何疑问、意见或建议，可通过应用市场页面或相关公开联系方式与我们联系。
This Privacy Policy applies to the iOS application “Study Math” and its related in-app features, including early math learning, level-based challenges, number recognition, counting practice, shape learning, comparison practice, pattern training, addition and subtraction practice, thinking training, rewards center, and parent center.
This Policy explains how we approach privacy, how local data is handled, and how system services and purchase status may be used during app usage.
During normal use of this app, we do not require and do not actively collect the following:
To support math challenges, learning progress, reward display, and parent-facing learning status features, the app may store certain data locally on your device, such as:
This information is mainly used to maintain app functionality and the learning experience on your device. It is not shared externally and is not centrally stored through our own servers.
Study Math mainly provides local early math learning and level-based activities. It generally does not require access to the camera, photo library, or microphone.
This app does not require your precise location information and does not create user profiles based on location.
The app may provide voice prompts, tap sounds, and answer feedback sound effects to improve the child-friendly experience. These settings are stored locally on the device and are not uploaded to a server.
The core learning features of the app are mainly designed to run locally. If App Store in-app purchases, purchase restoration, or system verification are involved, Apple system services may be used.
We take the safety and privacy of children seriously. This app is designed to provide a simple, gentle, and child-friendly early math and thinking training experience.
Because the app does not include an account system and does not collect or retain children’s personal information through our own servers, we do not actively create profiles for child users.
For features such as in-app purchases, parent center, and purchase restoration, we recommend that parents or guardians assist with the operation.
The app may provide App Store in-app purchases or membership unlock features. Related purchase, payment, subscription, and restore-purchase processes are supported by Apple App Store system capabilities.
We do not directly collect sensitive payment information such as bank card numbers or payment passwords. Such payment information is processed by Apple according to its own rules.
The app may use purchase status returned by Apple system services to determine whether certain features have been unlocked locally on the device.
If the app uses official Apple system capabilities, such as App Store in-app purchases, purchase restoration, or system review prompts, those capabilities are provided and managed by the device operating system or Apple platform.
Relevant data handling may also be governed by Apple’s platform rules and system permission mechanisms. We recommend reviewing Apple’s official materials as well.
Since we do not collect your personal information through our own servers, we do not sell, rent, or share your personal information with advertisers, data brokers, or other commercial organizations.
Unless otherwise required by applicable law, we do not disclose your local learning records or personal data for operational purposes.
We try to minimize unnecessary data processing and keep the app as local as reasonably possible.
However, please understand that any data stored on a device may be lost because of device damage, system issues, accidental deletion, or app removal. Parents are encouraged to back up important device data when needed.
If future features change the way privacy-related matters are handled, we may update this Policy and display the latest version and effective date on this page.
If you have any questions, comments, or suggestions regarding this Privacy Policy, you may contact us through the app marketplace listing or other publicly available contact channels.
